A new system boiler with installation usually costs between £2000 and £3500. The exact price depends on the boiler size, brand, and how straightforward the installation is.
Extra costs can apply if you need a new hot water cylinder, upgraded pipework, a boiler relocation, or smart heating controls. These factors can increase the overall price of your installation.
Yes, larger homes or properties with multiple bathrooms usually need a higher-output system boiler and sometimes a bigger cylinder, which raises both equipment and installation costs.
A like-for-like replacement is normally cheaper because it involves less disruption and minimal changes to your heating system. Prices are usually toward the lower end of the range if the new boiler is installed in the same position.
Yes, keeping the boiler in the same location is more cost-effective. Moving it to a new position, adding a longer flue, or working in a hard-to-access area will increase the price. Labour costs can also vary by region.
