BOILER SERVICING, DIAGNOSTICS & REPAIRS IN BELFAST

01.

Boiler Servicing

Keep your boiler running safely and efficiently with a full service. I check combustion, flue performance, safety devices, seals, and key components to ensure everything is operating correctly.
Clear pricing and honest advice, with no hidden costs. Any faults identified during a service are explained clearly and quoted before any repair is carried out.

02.

Boiler Fault Diagnostics

Faults diagnosed correctly before any repair is recommended. If your boiler has lost pressure, stopped heating, or is showing a fault code, I’ll diagnose the issue and repair it quickly. I carry common parts for Baxi, Vaillant, Worcester, Ideal, and more, aiming for same-day fixes wherever possible.

03.

Landlord Gas Safety Certificates (CP12)

Landlords must renew certificates every 12 months. I provide fast, same-day CP12 checks and email certificates directly to you or your letting agent. Multi-property discounts are available.

04.

Plumbing Support

I handle smaller plumbing jobs – leaks, tap replacements, radiator issues – and I work with trusted plumbers for larger repairs when needed. You get one reliable point of contact for both gas and plumbing support.

05.

CENTRAL HEATING CARE

Keep your central heating running smoothly and efficiently. I balance radiators, bleed air, check pumps and valves, and make sure your boiler isn’t overworking or wasting energy.

06.

BOILER Replacements

Need a new boiler? I’ll help you choose the right model for your home, install it safely, and ensure everything meets Gas Safe standards. Honest advice and quality workmanship guaranteed.
