Replacing your boiler, from the first survey to the final test
Most boilers give you warnings before they fail. Frequent breakdowns, a pilot light or display that keeps cutting out, banging or whistling from the unit, rising gas bills and visible leaks or rust are all signs. If the boiler is more than 10 to 15 years old, replacement usually makes more sense than another repair.
We start with a survey of your home: how many bathrooms, how much hot water you use, the pipework and where the flue can safely go. Then we recommend one of three types. A combi heats water on demand and suits most flats and smaller homes. A system boiler works with a hot water cylinder for busy households. A regular boiler suits older homes with a tank in the loft.
A full installation includes:
- Removing and disposing of your old boiler
- Fitting the new boiler, flue and condensate pipe
- A magnetic filter and system cleaning to protect the new unit
- New controls or a smart thermostat if you want one
- Commissioning, Building Regulations notification and your paperwork
- A walk-through so you know how to use it
Four stages, no surprises on the day
A boiler swap is a gas job, so every stage is done to Gas Safe and manufacturer requirements.

Survey and written quote
We check the existing boiler, pipework, flue route and hot water needs, then give you a clear quote and a recommendation, not a hard sell.

Strip out and prepare
We isolate the gas and water, drain down, remove the old boiler and protect your floors. The system is then flushed to clear sludge and debris.

Fit and connect
The new boiler is mounted, the flue and condensate pipe are run to the manufacturer's instructions, and the magnetic filter and controls are fitted.

Boiler replacement questions, answered
Should I repair or replace my boiler?
If it is under about 10 years old and the fault is minor, repair is usually sensible. If it is older, breaking down often or parts are hard to find, replacing it tends to cost less over time. We will give you an honest view after inspecting it.
Which type of boiler do I need?
It depends on your hot water demand and space. Combi boilers suit most smaller homes. System or regular boilers are better where several bathrooms are used at once. We explain the options at the survey.
How long does a replacement take?
A like-for-like swap is often completed in a day. Moving the boiler, changing the type or running a new flue takes longer. We confirm the timing in your quote.
Will I need new radiators or pipework?
Not always. Many existing radiators and pipes can be reused after a proper system clean. We will tell you if anything is worn or unsuitable before work starts.
What paperwork do I get?
You get the commissioning checklist, the manufacturer's warranty details and confirmation that the installation has been notified under Building Regulations. Keep these safe, as they matter when you sell your home.
What affects the cost of a new boiler?
The type and output of the boiler, the brand, whether the flue or boiler position changes, the condition of the existing system, and extras such as smart controls or a new cylinder.
