If you’re planning a new boiler in Lancing, it’s completely normal to feel a bit unsure about what the actual day will look like. Will the heating be off all day? Is it going to be noisy? How much disruption should you expect? These are the kind of questions we hear all the time. The truth is, once you understand the new boiler process, it’s far less daunting than it sounds. A properly planned boiler installation day is structured, organised and handled with care. Here’s exactly what tends to happen, step by step, so you know what to expect before the van even pulls up. Pre-install preparation Good preparation makes all the difference. Before installation day, you’ll usually have had a survey so the engineer can check your existing system, pipework, flue route and water pressure. This is when decisions are made about boiler location, controls and any upgrades needed to bring things up to current regulations. You might be asked to clear a bit of space around the existing boiler, airing cupboard or kitchen unit. Moving cleaning products, coats or stored bits and pieces makes access quicker and safer. If the boiler is in the loft, making sure the hatch is clear and there’s a safe working platform is important too. On the day itself, floors are usually protected with dust sheets from the front door to the work area. Most homeowners are pleasantly surprised at how tidy it is. Modern boiler fitting steps are far more contained than they were years ago.   Arrival and safety checks Installation normally starts first thing in the morning. The engineer will confirm the plan with you, talk through what’s happening and answer any last-minute questions. It’s a good time to mention anything specific, like needing heating back on early because you’ve got young children coming home from school. Before any tools come out, safety checks are carried out. These typically include: Isolating the gas supply Turning off the water supply if required Checking electrical connections Ensuring ventilation and flue routes are correct Gas Safe regulations are strict for good reason. Every step is methodical. Nothing gets rushed. You may hear tapping on pipework or see pressure gauges being checked. That’s all part of making sure the system is safe to work on.   Removal of the old boiler This is often the noisiest part of the boiler installation day. The old boiler is drained down and disconnected. Water from the system is carefully released and captured, though you might hear some gurgling through the pipes while it empties. Once isolated, the boiler casing comes off and connections are removed. Older boilers can be surprisingly heavy, especially traditional floor-standing models. If it’s mounted on a kitchen wall, that cupboard you’ve had since the early 2000s suddenly feels a bit roomier once it’s gone. If the new boiler is being fitted in a different position, additional work may be needed to reroute pipework or adjust the flue. In homes around Worthing and Shoreham-by-Sea, we sometimes see awkward older flue positions that need updating to meet modern standards. The old appliance is then taken away for proper disposal and recycling. Nothing gets left behind.   The installation process Mounting and pipework Now the new unit goes in. If it’s a combi boiler replacing a combi in the same spot, this part is fairly straightforward. The boiler is mounted securely on the wall and levelled. New brackets are used rather than reusing old fixings. Pipework is connected carefully and neatly. One of the key boiler fitting steps is making sure water flow and return pipes are set up correctly for efficiency. Magnetic filters are often added at this stage to protect the new boiler from sludge and debris. Flue and condensate The flue is fitted or adjusted to ensure combustion gases exit safely. Modern boilers produce condensate, which is a slightly acidic water by-product. This needs to drain away correctly, usually to a waste pipe. In colder coastal areas like Southwick, positioning of the condensate pipe matters to help prevent freezing during winter. A good installer will insulate and route this properly. System cleanse and filling Before firing up the new boiler, the system may be flushed to remove debris. If it’s not a full powerflush, at the very least the water is treated with inhibitor to reduce corrosion. The system is then refilled and pressurised. Radiators might be bled to remove trapped air. You’ll often hear the engineer moving from room to room briefly during this stage.   Testing and certification With everything connected, the boiler is powered up and tested. This isn’t just a case of switching it on and hoping for the best. Detailed checks are carried out on gas pressure, combustion readings and system performance. Controls and thermostats are set up and paired if needed. If you’ve opted for smart controls, this is when you’ll be shown how to use the app and adjust timers. Many homeowners admit they’ve never fully understood their old heating controls, so this is a good opportunity to start fresh. Once testing is complete, the installation is registered with Gas Safe and you’ll receive certification. This paperwork is important for warranty and if you ever sell your home.   Aftercare tips and what to expect next By late afternoon, in most straightforward installations, your heating and hot water should be fully operational again. The engineer will tidy up, remove debris and walk you through the basics: How to adjust temperature settings How to top up pressure if it drops What normal sounds are When to book annual servicing It’s common to hear slight expansion noises in the first few days as the system settles. That’s usually nothing to worry about. If something doesn’t seem right, you should always feel comfortable calling your installer for advice. A well-installed boiler should run quietly, heat your home evenly and provide consistent hot water without those sudden cold bursts older systems sometimes produce. Many customers tell us the first

If you’ve ever looked into upgrading your heating system in Lancing, you’ve probably come across combi boilers. They’re now one of the most common types of boilers in UK homes – but a key question many people ask is: can you actually convert your current system to a combi boiler? The short answer is yes – many homes can be converted. However, whether it’s the right choice depends on your property, your water usage, and how your existing system is set up. This guide explains how combi conversions work, when they’re suitable, and what to consider before making the switch. What Does “Converting to a Combi Boiler” Mean? A combi boiler conversion involves replacing a traditional heating system—typically a regular (heat-only) or system boiler – with a combi boiler. Traditional systems usually include: A hot water cylinder (often in an airing cupboard) A cold water storage tank (usually in the loft) A combi boiler removes the need for both. Instead, it heats water directly from the mains whenever you turn on a tap or shower. This creates a more compact and simplified system overall.   Is It Possible to Convert Any Home? In many cases, yes – it is technically possible to convert most homes to a combi boiler. But “possible” doesn’t always mean “ideal.” The suitability of a combi conversion depends on a few key factors: Mains Water Pressure Combi boilers rely entirely on mains pressure. If your water pressure is low, you may find: Weak showers Reduced flow from taps Homes with strong, consistent water pressure tend to get the best results from a combi system. Size of the Property Combi boilers are typically best suited to: Flats Small to medium-sized homes Properties with one bathroom Larger homes with multiple bathrooms may struggle with a combi system if several hot water outlets are used at the same time. Hot Water Demand Because combi boilers heat water on demand, they have limits. If your household regularly uses: Multiple showers at once Hot water in different rooms simultaneously You might find a combi system less effective than a system or regular boiler.     What Happens During a Combi Conversion? A combi conversion is more involved than a simple boiler swap, because it changes how your whole heating system works. The process usually includes: Removing the hot water cylinder Removing the cold water tank Installing the combi boiler Modifying pipework to suit the new system Connecting the boiler to the mains water supply Because of this, conversions take longer than straightforward replacements.     How Long Does It Take? Most combi conversions take between: 2 to 4 days This can vary depending on: The complexity of your existing system Whether the boiler is being relocated Any additional upgrades required     What Are the Benefits of Switching to a Combi Boiler? Space Saving Removing tanks and cylinders can free up valuable storage space—especially useful in smaller homes. Instant Hot Water There’s no need to wait for a tank to heat up. Hot water is available whenever you need it. Energy Efficiency Modern combi boilers are highly efficient and only heat water when required, which can help reduce energy waste. Simpler Setup With fewer components, combi systems are generally more straightforward to maintain compared to traditional setups.     Are There Any Downsides? Limited for High Demand If multiple taps or showers are used at once, water pressure can drop. No Backup Hot Water With no storage tank, you don’t have a reserve of hot water if demand suddenly increases. Reliance on Mains Pressure Performance depends entirely on your incoming water supply.     Do You Need to Upgrade Your System? Sometimes, yes. A combi conversion may require additional work, such as: Pipework adjustments System cleaning (powerflush) Upgraded controls or thermostats These changes help ensure the new boiler works efficiently and reliably.     Is It Always Worth Converting? Not necessarily. While combi boilers suit many modern homes, they’re not always the best option. A conversion is often worthwhile if: You want to save space You have moderate hot water usage Your home has good mains pressure However, if your home has high water demand or multiple bathrooms, sticking with a system boiler could be the better choice.     So, Can You Convert to a Combi Boiler? In most cases, yes, you can convert to a combi boiler. But whether you should depends on your home’s setup and your household’s needs. It’s less about what’s possible and more about what’s practical. Understanding how your current system works, how much hot water you use, and what your water pressure is like will help you decide if a combi conversion is the right move.     Final Thoughts Combi boilers have become a popular choice for good reason, they’re compact, efficient, and convenient. But like any heating system, they’re not one-size-fits-all. If you’re considering a combi boiler conversion in Lancing or the surrounding areas, contact us today, we can assess your property and see if it’s suitable for a combi boiler.

If you are looking at getting a new boiler installed in Shoreham and you have a typical three bedroom house, one of the first questions you will ask is simple enough: what is the best boiler for a 3 bed house? It sounds straightforward, but the answer depends on how your home is laid out, how many bathrooms you have and how your family actually uses hot water day to day. We get this question all the time from families upgrading an older system. Some are dealing with a noisy heat-only boiler in the airing cupboard. Others have just moved in and found the current boiler is struggling to keep up. In this guide, we will walk you through boiler types, sizing and efficiency so you can make a confident decision. Boiler types explained Before choosing a model, it helps to understand the main types of boiler available. Most three bedroom homes will suit one of the following. Combi boilers A combi, short for combination boiler, provides heating and hot water directly from the unit. There is no separate hot water cylinder or cold water tank. When you turn on a tap, the boiler fires up and heats the water instantly. They are compact and ideal where space is tight. We often fit them in kitchen cupboards or small utility rooms. For many homes with one bathroom and decent mains pressure, a combi is a practical, tidy solution. System boilers A system boiler works with a separate hot water cylinder, usually kept in an airing cupboard. Unlike older conventional setups, most key components are built into the boiler itself, which keeps installation fairly straightforward. This type is a good option for homes with more than one bathroom or where several people may want hot water at the same time. Because hot water is stored, you can run a shower and a tap together without as much drop in performance. Heat-only boilers Also known as regular or conventional boilers, these use both a cylinder and a cold water tank in the loft. They suit certain older properties, particularly where the pipework is already set up that way. However, for most upgrades in a three bedroom house, homeowners tend to move towards combi or system options. Read more about the differences between combi, system and regular boilers.     Sizing considerations Choosing the correct output is just as important as choosing the type. This is where a proper boiler size guide comes in. Boiler size is measured in kilowatts and it relates to the heating and hot water demand of your home, not the physical dimensions of the unit. For a typical three bedroom house with one bathroom and around 8 to 12 radiators, you are generally looking at: 24 to 30kW combi boiler 18 to 26kW system boiler for heating plus an appropriately sized cylinder That said, there are always exceptions. A well insulated modern estate home in Shoreham might need less output than a draughty older property near the seafront in Worthing where we often find solid walls and higher heat loss. Loft conversions, underfloor heating and large towel rails all add demand too. An oversized boiler will not necessarily heat your home better. In fact, it can cycle on and off too frequently, which reduces efficiency and increases wear. Undersizing can leave you with lukewarm radiators on colder days. A proper heat loss calculation carried out in person is the safest way to get it right.     Combi vs system boiler: which is better for a 3-bed house? The combi vs system boiler debate comes up on almost every quote. The truth is, there is no one-size-fits-all answer. It depends on how your household uses hot water. A combi boiler is usually the best boiler for a 3 bed house if: You have one main bathroom Mains water pressure is good You want to free up space by removing tanks and cylinders Hot water demand is spread out rather than all at once A system boiler is often the better choice if: You have two bathrooms or an ensuite Showers are used at the same time in the morning You prefer the reassurance of stored hot water For example, we recently spoke to a family of five in Lancing. With back to back showers before school, their old combi was struggling. In that case, upgrading to a system boiler with a correctly sized cylinder made much more sense and gave them consistent performance.     Energy efficiency and running costs Modern boilers are far more efficient than those fitted 15 or 20 years ago. Most new models are rated A for efficiency and use condensing technology to capture and reuse heat that would otherwise be lost. Efficiency is not just about the boiler itself. Controls play a part too. Smart thermostats, weather compensation and properly balanced radiators all help reduce gas use. We often find older systems where the radiators have never been balanced properly, which means some rooms overheat while others stay chilly. Upgrading your boiler gives you the opportunity to improve the whole system. Over time, lower gas consumption can make a noticeable difference to annual bills, especially in a busy family home.     Recommended models for a 3-bedroom home There are several reliable manufacturers on the UK market. The right choice will depend on budget, warranty preference and system type, but in a typical three bedroom property we often recommend models from well known brands such as: Worcester Bosch for solid build quality and long warranties Vaillant for quiet operation and strong hot water performance Ideal for good value and compact combi options Rather than focusing purely on brand, we advise looking at the warranty length, availability of local parts and how straightforward the boiler is to service. A good installation matters just as much as the badge on the front.   Expert advice before you decide If you are unsure which boiler is right, it is worth having a proper home visit

If you’re a landlord in Worthing, you’ve probably heard the term landlord gas safety certificate more times than you can count. It comes up when you’re buying a rental property, signing new tenants, or sorting renewals. But I still get plenty of calls from landlords asking what it actually involves and when it’s needed. It’s one of those jobs that sounds straightforward but has very clear legal responsibilities behind it. As heating engineers working across Worthing and the surrounding areas, we see first-hand how important it is to get this right. Not just to tick a box, but to protect your tenants and yourself.   Legal requirements for landlords If you rent out a property in the UK, you are legally responsible for making sure all gas appliances, pipework and flues are safe. That applies whether it’s a single flat above a shop or a three-bedroom house with a combi boiler in the kitchen. The law requires you to have a valid landlord gas safety certificate for each rental property. This is formally known as a Gas Safety Record. It must be carried out by a Gas Safe registered engineer and renewed every 12 months. Once completed, you need to: Give a copy to existing tenants within 28 days of the check Provide it to new tenants before they move in Keep a copy on file for at least two years I often get asked, “Does it matter if my tenant says everything’s working fine?” The short answer is yes, it still matters. Even if the boiler seems perfect, the annual check is a legal obligation. It’s not optional and it’s not something you can leave until there’s a problem.     What the inspection includes A proper gas safety inspection is more than just a quick look at the boiler. When we carry out a landlord gas safety certificate, we follow a set process to make sure the entire system is safe. Appliance checks We test every gas appliance provided by the landlord. That usually includes the boiler, gas hob, oven and sometimes a gas fire. We check that each appliance is operating at the correct pressure and burning gas safely. If you’ve got an older property in Worthing with a back boiler or an ageing gas fire that tenants rarely use, it still needs to be inspected if it’s connected. Flue and ventilation checks We check that flues are properly fitted and not blocked. In coastal areas like ours, corrosion can be an issue, especially with external flue terminals exposed to salty air. Ventilation is also important. Boilers in cupboards need adequate airflow. We often come across situations where cupboards have been boxed in or altered after a kitchen refit, restricting ventilation and creating a risk. Gas tightness test We carry out a tightness test to make sure there are no gas leaks on the system. Even a small undetected leak can become dangerous over time. If everything is safe and compliant, we issue the landlord gas safety certificate. If we find a fault, we’ll explain clearly what needs to be done. In some cases, we may have to cap an appliance straight away if it poses immediate danger. It’s not something landlords like to hear, but safety always comes first.     Renewal rules and timing A landlord gas safety certificate is valid for 12 months from the date of the check. However, there’s a bit of flexibility that many landlords don’t realise. You can renew the certificate up to two months before it expires without losing the original renewal date. So if your certificate runs out at the end of June, you can have the inspection done any time from 1 May and still keep the June renewal date for the following year. This is particularly useful if you manage multiple properties. It allows you to keep them all on a similar schedule rather than juggling inspections throughout the year. One common question we’re asked is what happens if tenants refuse access. As a landlord, you’re expected to take reasonable steps to arrange the inspection and keep records of your efforts. Emails, letters and appointment reminders should all be documented. It’s about showing that you’ve done everything you reasonably can to comply. Leaving it until after the expiry date can lead to serious consequences, including fines and difficulties with insurance claims. It’s simply not worth the risk. If you’re managing property in Littlehampton, Rustington, East Preston, Ferring, Worthing, Lancing, Shoreham-by-Sea or Southwick and need straightforward advice, we’re always happy to talk it through. At N J Lees Plumbing & Heating Ltd we work with landlords across the local area every week, from single-property owners to those with growing portfolios. N J Lees Plumbing & Heating Ltd understands that compliance can feel like paperwork and deadlines, but it’s really about keeping people safe and protecting your investment.

If you’ve got a boiler tucked away in a cupboard somewhere in Worthing, there’s a good chance you don’t think about it until something goes wrong. We see that all the time. The heating packs up on a cold morning, or there’s no hot water before work, and suddenly it’s urgent. One of the most common questions we get from homeowners is about boiler repair vs servicing. Aren’t they basically the same thing? Not quite. They’re both essential, but they serve very different purposes. In this post I’ll break down what each one involves, when you need them and why keeping on top of boiler maintenance is usually cheaper and far less stressful in the long run.   What Boiler Servicing Involves A boiler service is preventative. It’s about checking that everything is working safely and efficiently before problems develop. When we carry out a service, we’re not just giving it a quick once-over. A proper annual service includes: Checking the appliance casing and seals Inspecting internal components for wear or corrosion Cleaning key parts like the burner and heat exchanger if required Testing gas pressure and flow Checking flue integrity and combustion readings Making sure safety devices are working correctly We’ll also look at the system as a whole. That might mean checking the pressure, bleeding a radiator if needed or spotting early signs of sludge build-up. In homes near the coast around Worthing and Ferring we often see corrosion a bit earlier because of the salty air, so that’s something we keep an eye on. A service is usually planned. It’s booked in advance, done once a year and keeps your manufacturer’s warranty valid. Most importantly, it helps prevent breakdowns in the first place. Think of it like an MOT for your boiler. You wouldn’t wait for your car to fail before getting it checked. The same logic applies here.   What Boiler Repairs Involve A repair is reactive. Something has already stopped working or isn’t working properly. Typical calls we get out to include: No heating or hot water Boiler making loud banging or whistling noises Error codes on the display Leaks underneath the boiler Pressure constantly dropping In these cases, we diagnose the fault, identify the failed component and replace or repair it. Sometimes it’s something straightforward like a faulty thermostat or diverter valve. Other times it can be more involved, especially if the boiler hasn’t been serviced regularly. A repair focuses on fixing that specific issue. It doesn’t automatically mean the rest of the boiler is in good condition. That’s where people can get caught out. The immediate problem is sorted, but underlying wear and tear is still there ticking away. So when homeowners ask about boiler repair vs servicing, I often explain it this way: a service aims to stop breakdowns happening, a repair deals with them once they have.   Why Both Matter Some people think if their boiler is running fine, there’s no need for a service. Others assume if they’ve just had a repair, they can skip the annual check. In reality, both play different roles. Regular servicing helps: Keep your boiler running efficiently which can lower energy bills Extend the lifespan of the appliance Maintain manufacturer warranties Reduce the risk of unexpected breakdowns Ensure the appliance is operating safely Repairs on the other hand are sometimes unavoidable. Even well-maintained boilers can develop faults over time. Components wear out. Sensors fail. That’s normal. What we find across homes in this area is that boilers which are serviced every year tend to have fewer major breakdowns. When they do need a repair, it’s often smaller and less expensive because problems were picked up early. I’ve been into properties where the boiler hasn’t been touched in five or six years. By the time it fails, there are multiple issues stacked on top of each other. At that point the decision can sometimes shift from repair to replacement, which is a much bigger expense. Understanding the difference between boiler repair vs servicing helps you plan properly. A service is routine maintenance. A repair is problem solving. They’re not interchangeable.   Final Thoughts If you’re a homeowner in Littlehampton, Rustington, East Preston, Ferring, Worthing, Lancing, Shoreham-by-Sea or Southwick, it’s worth thinking about when your boiler was last properly checked. If you can’t remember, it’s probably due. At N J Lees Plumbing & Heating Ltd we carry out both repairs and annual servicing across the local area. We’ve worked in all sorts of properties from older seaside terraces to newer-build estates and the approach is always the same: honest advice, clear explanations and no unnecessary work. If you’re ever unsure whether you need a repair or just routine maintenance, just ask. N J Lees Plumbing & Heating Ltd will walk you through it and explain your options in plain English. The simplest way to avoid unexpected breakdowns is to stay ahead of them. Book a boiler service  

If you own a home in Worthing, chances are your boiler is quietly getting on with the job in a cupboard, loft or kitchen corner without much attention. That is until it stops. One minute you have heating and hot water, the next you are boiling kettles and ringing round for quotes. It is at that point many homeowners start asking about boiler finance options UK. We speak to people every week who were not planning to replace their boiler this year. The breakdown forces the decision. This guide is here to explain what your options are, in plain English, and help you decide what feels manageable for your budget. Why Boilers Are Often Financed A new boiler is not a small purchase. Even when everything goes smoothly, you are paying for the appliance itself, the installation and often upgrades to controls or pipework to meet current regulations. Very few homeowners have a boiler fund sitting ready and waiting. More often, it is an unexpected failure in the middle of winter. I have lost count of the times I have stood in someone’s kitchen while they say, “We just weren’t ready for this.” Financing spreads the cost over monthly payments rather than one larger upfront sum. For many households, that makes the difference between patching up an old unreliable boiler yet again and replacing it properly with something efficient and covered by warranty. It can also allow you to choose a better model. Instead of going for the cheapest option just to keep the upfront cost down, finance can give you access to a more efficient boiler that lowers your gas bills long term.   Common Boiler Finance Options Interest-Free Finance Some installers offer interest-free credit over a fixed term. This means you spread the cost over, say, 12 or 24 months without paying extra in interest. This tends to suit homeowners who can comfortably manage the monthly payments and want to clear the balance relatively quickly. Low Interest Monthly Payments Another common option is a longer-term agreement with interest included. The repayment period might be several years, which reduces the monthly amount. For families juggling mortgages, childcare and everyday bills, this can feel more realistic. It makes a new boiler affordable without putting too much pressure on monthly outgoings. Buy Now, Pay Later Some plans offer a short deferred period before payments start. This can be useful if you are dealing with other unexpected costs at the same time, such as roof repairs or electrical work. As with any credit agreement, it is important to understand what happens when the deferred period ends and what interest may apply. When people ask us about boiler finance options UK, the key thing we say is this: the right option depends on your own circumstances. There is no single best answer for everyone.   The Benefits of Financing a Boiler The most obvious benefit is affordability. You get heating and hot water back quickly without waiting to save up the full installation cost. There is also the comfort factor. Modern boilers are far more efficient and reliable than older models. I still see 18 year old units in lofts around Worthing and the surrounding areas, often struggling along and costing more in repairs each winter. Replacing them sooner rather than later can reduce breakdown stress. Financing can also help with: Upgrading to smart controls Improving energy efficiency Gaining longer manufacturer warranties Avoiding repeated repair costs on old systems When customers compare the monthly finance cost to what they were spending on repeated callouts and parts, it often makes financial sense.   Key Considerations Before You Decide Before signing any agreement, take time to look at the total amount repayable, not just the monthly figure. A lower monthly cost over a longer term may mean paying more overall. Think about your circumstances over the next few years. Are there changes ahead such as moving house or other major expenses? It is worth checking whether you can settle the agreement early and if there are any charges for doing so. Make sure the boiler being installed is genuinely suitable for your home. Finance should not be used to oversell you something far bigger than you need. A three bedroom semi in Lancing does not need the same output as a large detached property in Shoreham-by-Sea. Correct sizing is key. Finally, choose an installer you trust. Financing is only one part of the decision. The quality of the installation matters just as much. Poor installation can invalidate warranties and cause years of frustration.
