Is your boiler approaching the end of its life? Are you considering upgrading to a more efficient heating system? Getting a replacement boiler doesn’t have to be stressful. This guide walks you through the process step-by-step, helping you understand what to expect from start to finish.
Step 1: Assess Your Current Boiler
The first step is determining whether your boiler needs replacement. If your boiler is over 15 years old, requires frequent repairs, or is no longer energy-efficient, replacement is likely a smart decision. Modern boilers are significantly more efficient than older models, which can reduce your heating bills by up to 30%. If your current boiler is still under 10 years old but has broken down, repair might be the better choice, but our engineers can advise you on this.
Step 2: Choose Your New Boiler
Selecting the right boiler is crucial. At NJ Lees, we’re Worcester Accredited Installers, meaning we specialise in Worcester Bosch boilers, reliable, efficient, and backed by excellent warranties. Consider your home size, the number of bathrooms, and your heating demands when choosing a boiler type. Combi boilers are ideal for smaller properties, while system boilers or conventional boilers suit larger homes with higher hot water demands.
Our engineers will help you select the most suitable model for your property and budget. We can also discuss renewable heating options like solar hot water systems if you’re interested in going green.
Step 3: Get a Professional Survey and Quote
Before any work begins, one of our Gas Safe registered engineers will visit your home to conduct a comprehensive survey. They’ll assess your current heating system, check the condition of your pipework and radiators, and discuss your heating needs. Based on this survey, they’ll provide you with a detailed quote that outlines the cost of the boiler, installation, removal of the old unit, and any additional work required such as system flushing or pipe upgrades.
Step 4: Discuss Installation Timeline
Once you’ve accepted the quote, you’ll schedule an installation date. Most boiler replacements can be completed in one or two days, depending on the complexity of the work. We’ll confirm the date in advance, and our team will arrive on time with all necessary equipment. During installation, you’ll be without heating and hot water temporarily, so plan accordingly.
Step 5: Professional Installation
Our team will remove your old boiler safely, install the new one, and connect it to your existing heating system. We’ll perform full testing and commissioning to ensure everything works perfectly. Safety checks are completed to meet legal requirements, and you’ll receive all necessary documentation and certificates.
Step 6: Aftercare and Support
Your new boiler comes with comprehensive support. We’ll provide you with all manuals and warranties, and we’ll be available for any questions or support you need. We recommend booking an annual service to keep your boiler running efficiently and maintain your warranty.
