Central Heating Installation — Compare Local Engineers

Central heating installation with new radiators and pipework

Whether you're installing central heating from scratch, extending it to a new room, or replacing an old, inefficient system, you need a qualified engineer to do it safely and properly. BoilerFinder UK lists Gas Safe registered heating installers across the UK.

What a central heating system includes

The boiler (the heat source)
Radiators in each room
Pipework connecting it all
Controls, a thermostat and often smart heating controls

A well-designed system heats every room evenly, runs efficiently, and keeps your energy bills down.

What to expect from an installation

A good installer will survey your home, recommend the right boiler size and radiator layout, give you a fixed quote, and then fit the system, balance it, and register the work. They'll also talk you through the controls before they leave.

How much does central heating installation cost?

Installing a full central heating system typically costs £3,000–£5,000+, depending on the size of the property, the number of radiators and the boiler you choose. Adding a single radiator to an existing system is far cheaper.
