Affordable, Efficient, and Professional Boiler Replacement Services
4.3/5 from 8 Trust Pilot
4.8/5 from 189 Google Reviews The right boiler depends on more than the number of radiators you have. Your bathrooms, hot water usage, existing system and available space all matter. We check your current setup before recommending a replacement. That includes the boiler location, pipework, flue route, controls and any hot water cylinder. You receive practical advice and a written quotation, so you know what you’re buying and what the installation involves.

A breakdown does not always mean you need a new boiler. We can assess the fault and explain whether repair or replacement makes more sense.
Replacement may be worth considering when:
Breakdowns and repair costs are becoming frequent.
Suitable replacement parts are difficult to obtain.
Your boiler no longer meets your household’s hot water needs.
A major repair would be expensive compared with replacement.
You’re changing your heating system or renovating your home.
We explain your options so you can make an informed decision.
A combi boiler provides heating and hot water without a separate hot water cylinder. It can be a practical option where space is limited, depending on water supply and household demand.
A system boiler works with a separate hot water cylinder. It may suit homes with several bathrooms or greater demand for hot water.
Also called regular or conventional boilers, these work with a separate cylinder and usually feed tanks. They can be suitable for homes with an existing traditional heating system.
We explain the options and recommend a suitable type and output after assessing your property.
Your quotation sets out the work required for your particular installation, including:
The recommended boiler and model.
Installation labour and materials.
Removal and disposal of the existing boiler.
Flue arrangements and any necessary pipework changes.
Heating controls and any agreed upgrades.
System cleaning or flushing appropriate to the installation.
Testing, commissioning and installation paperwork.
Manufacturer warranty arrangements.
Any additional work identified during the assessment is explained before you approve the quote.
The price depends on the boiler you choose and the work needed to install it.
A replacement in the same position usually involves less work than moving the boiler or changing the system type. Flue access, pipework alterations, controls and the condition of your heating system can also affect the cost.
