Expert Boiler Installation in Chelsea
Replacing an old or unreliable boiler is one of the best ways to cut your energy bills and keep your home warm. Chelsea Plumbers 247 provide professional boiler installations across Chelsea and the surrounding SW3, SW7, SW6, SW5, SW10, SW1V, SW1X and SW1W areas. As Worcester Bosch and Vaillant accredited installers, our Gas Safe registered engineers fit high-quality, energy-efficient boilers built to last.
Every installation starts with a free, no-obligation survey. We look at your current system, your hot water demand and the layout of your home before recommending the most suitable boiler — whether that's a combi, system or conventional unit. You'll receive a clear written quote up front, so you know exactly what's included with no surprises later.
We install boilers to suit Chelsea homes, from period conversions near Sloane Square to newer apartments in World's End, taking account of space, demand and the mineral content of local water.
Our engineers work cleanly and tidily, protecting your home throughout the job and leaving everything spotless. Once fitted, we fully commission the boiler, walk you through the controls and register the installation so your manufacturer's warranty is in place. It's a straightforward, professional service from a family-run team you can trust.
Not sure if you need a new boiler or just a repair? Our boiler repair service includes an honest assessment — we'll tell you which option makes more sense for your situation.

Boiler installation and replacement in Chelsea
If you need a plumber in Chelsea for a new boiler, our team handles installs for flats, period conversions and family homes across SW3 and nearby postcodes. We can advise on the right setup for your property, whether you are replacing an old unit or planning a full heating upgrade.
Combi Boiler Installation
A combi boiler is often a practical choice for smaller homes and apartments, especially where space is tight and hot water demand is straightforward. Our engineer checks your gas supply, water pressure and existing pipework, then sizes and installs a model that suits the property and daily usage.
System Boiler Replacement
System boilers work well where there is a stored hot water cylinder and more than one bathroom to serve. We assess the current layout, replace the old unit with the correct output, and make sure the controls, venting and system pressure are set up properly for reliable performance.
Back Boiler Removal
Back boilers in older Chelsea houses can be inefficient, awkward to service and costly to run. We safely remove the unit, cap or reroute any affected pipework, and install a modern replacement boiler so you gain better efficiency and a cleaner, more practical heating setup.
Boiler Relocation Work
Moving a boiler is often needed during a kitchen refit, loft conversion or when improving the flow of a compact flat. We plan the new position carefully, check flue routes and condensate drainage, then move the boiler with minimal disruption to your home and heating system.
Boiler Cost Quotes
Boiler installation costs depend on the type of boiler, the condition of the existing system and any extra work needed on flueing, controls or pipework. We provide clear quotes after assessing your property, so you know what is included before any work starts, with no vague allowances.
Warranty And Servicing
Most manufacturers require annual servicing to keep the warranty valid, and that also helps catch wear before it turns into a breakdown. We fit boilers from trusted brands, register the warranty correctly and can arrange yearly servicing to keep the system running efficiently and safely.
Frequently Asked Questions
A straightforward like-for-like combi boiler swap typically takes one day. If the installation involves moving the boiler to a new location, changing the flue, or upgrading pipework, it may take a day and a half to two days. We'll give you a clear timeline before work starts so you can plan accordingly.
The right boiler depends on your home's size, the number of bathrooms, and your existing system. Combi boilers are popular for smaller homes with one bathroom as they heat water on demand. System boilers suit larger homes with multiple bathrooms. Our engineers will assess your property and recommend the most suitable option for your needs and budget.
We always give you an honest opinion. If your boiler is less than 10 years old and working reasonably well, a service and repair may be all that's needed. If it is older, frequently breaking down, or no longer efficient, a new boiler installation will save you money on energy bills in the long run.
Yes. We stand behind our workmanship and all installations are completed to manufacturer and Gas Safe standards. Worcester Bosch and Vaillant boilers come with manufacturer warranties — we can advise on registration and the terms for your specific model. If anything goes wrong after installation due to our workmanship, we'll come back and sort it at no extra charge.
Yes — we remove and responsibly dispose of your old boiler as part of the installation service. You don't need to arrange anything separately.
