New Boiler Installation

01

New Boiler Installation

Combi, system and regular boilers from A-rated brands

A new boiler is the biggest single upgrade most homes make to their heating, and it's the work we're best known for. As a Gas Safe registered, Worcester Bosch accredited and Vaillant approved installer, we fit A-rated combi, system and regular boilers — with the longer manufacturer warranties registered for you.

Power Flushing

05

Power Flushing

Clears sludge to restore heat — free with a new boiler

Cold spots at the bottom of radiators, noisy boilers and slow warm-ups usually mean sludge in the system. A power flush clears it out, restoring circulation and protecting a new boiler. It's included free with every new boiler installation, and available on its own.

Central Heating System Extension

06

Central Heating System Extension

Adding radiators, extending pipework and upgrading zones

Not every heating job is a new boiler. We also extend and improve existing systems — adding radiators to cold rooms, running new pipework to an extension or loft conversion, and upgrading the zones and controls so different parts of the house heat independently.

Magnetic Filter Installation

07

Magnetic Filter Installation

Catches sludge before it reaches the boiler

A magnetic filter is a small device fitted to the pipework that catches metallic sludge before it can reach and damage the boiler. We fit them as standalone protection for an existing system, and include one free with every new boiler installation.
