How It Works

01

Survey and recommendation

A Gas Safe engineer surveys your property, assesses current pipework, flue route and heating demand, then recommends a suitable condensing boiler and controls with a written, no-obligation quote.

02

Professional installation

Our team removes the old boiler where required, fits the new unit, installs or adapts flue and pipework, and integrates controls. We follow manufacturer instructions and Gas Safe regulations throughout.

03

Commissioning and handover

We commission the system, perform combustion and safety checks, balance radiators where needed and leave full documentation. Installations include a 12-month workmanship guarantee and manufacturer warranty where applicable.

Condensing boilers fitted correctly, not just dropped in. We regularly install Viessmann, Worcester Bosch and Vaillant condensing boilers, selecting the correct size and flue configuration to match your property. Proper commissioning and modulation setup are essential to achieve the factory-rated efficiency and reduce fuel bills over time.

Local, accountable team. Installations are planned and supervised by David Hurst, an Eng Tech MCIPHE engineer, and completed by Gas Safe registered operatives.

Frequently Asked Questions

Installation times vary with complexity and property type. A like-for-like swap in a standard house is usually completed within a day, while system upgrades, flue reroutes or work in period properties can take longer. Your survey will include an estimated timescale before any work starts.

Liked David's experience & credentials so asked him to quote for a boiler replacement, multiple radiator replacements, systems upgrade etc, due to poor heating. Very professional and easy to deal with fair quote and no surprises. He was thorough, methodical and you knew you were in safe, reliable hands. CH & HW system now working the best it has for many years. Highly recommend David & GRT.
