What moves the price
- Boiler type and output — a larger output boiler, or a system boiler with a cylinder, costs more than a small combi for a compact home.
- Installation complexity — changing from a conventional system to a combi means removing tanks and rerouting pipes, which takes far longer than like-for-like.
- Any necessary upgrades to existing systems — a new flue, updated controls or a power flush of old radiators add to the replacement.
- Gas lines — moving the boiler or upgrading the gas pipework adds work to the replacement.

How to pay less
- A like-for-like boiler replacement in the same spot avoids new pipework and flue changes, so it costs less than a system change.
- Choosing a boiler with an output that suits your home, rather than an oversized model, keeps the price and running costs down.
- Replacing an ageing boiler before it breaks down lets you book at a time that suits, instead of paying for an emergency job.
- Booking the boiler replacement in summer, when heating engineers are less busy, can give you more choice of dates and prices.
- Adding new heating controls during the boiler replacement costs less than booking them as a separate visit later.
Before you book
- Access to the area where the boiler is installed.
- Information on the current boiler's performance and any issues experienced.
- Details about the home's heating requirements and preferences.
- Any specific requests regarding the type of boiler or features desired.
- You can ask whether the installer is registered for gas work, and what warranty the new boiler and the installation carry.
