Boilers
Installation, Replacement & Servicing

Boilers

A new, energy-efficient boiler can cut your heating bills significantly while keeping your home reliably warm. Our Gas Safe engineers install all leading brands including Worcester Bosch, Vaillant, Viessmann, and Baxi.

What's Included

New Boiler Installation

Full supply and installation of combi, system, or heat-only boilers. We survey your property, recommend the right output, and complete the job with minimal disruption — usually in a single day.

Boiler Replacement

Upgrading an old, inefficient boiler to a modern A-rated unit. We handle removal of the old boiler, all pipework modifications, and commissioning of the new system.

Annual Boiler Service

A thorough safety and efficiency check covering the heat exchanger, burner, flue, controls, and all seals. Keeps your warranty valid and catches problems early.

Boiler Repairs

Fast diagnosis and repair of faults including no hot water, pressure loss, ignition failure, and error codes. We carry common spare parts to resolve most issues on the first visit.
