— Our Process

How It Works

01

Site survey & sizing

A Gas Safe engineer visits to survey pipework, flue route and heat loss — then recommends the correct combi, system or conventional boiler and controls for your property.

02

Supply & warranty registration

We order the chosen make (Vaillant or Worcester Bosch options), register the manufacturer warranty and confirm parts lead times to keep the install on schedule.

03

Installation, commissioning & handover

Engineers fit, pressure-test and commission the system to Gas Safe standards, provide paperwork and show you controls, maintenance needs and warranty documentation.

— Benefits

Why Choose us for Boiler Installation?

Accredited installers & backed warranties

Vaillant Advance Plus and Worcester Bosch accredited installers with Gas Safe, F‑Gas and NICEIC credentials — manufacturer warranties registered at handover.

Local, family-led team

Based in Coventry with 19 years’ experience, a hands-on management team and local engineers for rapid responses and reliable aftercare.

Right-size, futureproof design

We size systems for real performance, fit modern controls and advise on future upgrades (heat pumps, controls or solar compatibility) to protect your investment.

— FAQ

Frequently Asked Questions

Installation time varies by property and boiler type. A straightforward combi swap in a standard house can be completed in a day, while system or conventional installs that require cylinder work or pipe alterations may take longer. Your survey will confirm a realistic timescale before we start.
