How It Works

On-site heat-loss check, property assessment and radiator inspection to size the boiler and specify required controls, flue route and any cylinder or unvented works.

Full commissioning, performance checks, manufacturer registration and user demonstration. You receive certification and guidance on controls and servicing schedules.
Benefits
Why Choose us for Boiler Installation?
Two decades of proven expertise
20 years in domestic heating and a background as a British Gas engineer mean installations are efficient, compliant and built on real-world experience.
Gas Safe and manufacturer-backed
Gas Safe registration, G3 unvented and WaterRegs competence protect safety and compliance, while partnerships with Worcester, Vaillant and Glow-worm secure genuine parts and warranty registration.
Local, reliable service
A small Wirral-based team focused on domestic customers — responsive surveys, considerate installers, tidy finishes and clear commissioning paperwork.
What we install: We supply and fit combi, system and regular boilers from recognised manufacturers. Each installation starts with a heat-loss calculation and radiator appraisal so the boiler is correctly sized (kW) for your house type — whether a terraced Victorian in Birkenhead, a semi in Heswall or a detached home on the Wirral peninsular. Options include condensing flues, balanced flues for sealed-room installations and unvented cylinder connections where hot-water demand requires it.
Safe, compliant workmanship: All gas work is carried out by Gas Safe-registered engineers, and unvented systems are installed to G3 regulations with WaterRegs compliance for plumbing work. Installations include primary pipework, magnetic filters, automatic air vents, commissioning checks and manufacturer registration to protect warranties. We explain controls and programme a simple-to-use schedule, and leave a commissioning certificate and guidance so you know exactly how to operate and maintain your new system.
FAQ
Frequently Asked Questions
Most straightforward combi replacements are completed in a day, while system or regular-boiler installs that require cylinder work, new flue routes or radiators can take 1–3 days. Times depend on property access, boiler location and whether pipework or radiator upgrades are needed.
