Boiler Servicing in West & North West London
A boiler service is an annual Gas Safe check that keeps your boiler safe, efficient and protected for warranty purposes.
The Happy Heating Co services combi, system and regular boilers across West and North West London, checking combustion, flue performance, ventilation, seals, controls, pressure and visible signs of wear. Servicing can catch small faults before they turn into breakdowns, especially before winter when boilers work hardest.
If your boiler is making odd noises, using more gas than usual, showing intermittent faults or has not been serviced in the last 12 months, a proper service is the safest next step.
An annual boiler service by Gas Safe engineers keeps your boiler safe, your bills down and your warranty valid. Fixed price, full manufacturer checks and a clear written report.

Boiler servicing FAQs
Quick answers about boiler servicing, annual safety checks, warranty protection and Gas Safe engineers across West London and North West London.
Ask on WhatsAppHow much does a boiler service cost?
A standard boiler service with The Happy Heating Co costs £120, and our comprehensive service — a full strip-down and internal clean with new seals and electrodes, genuine manufacturer parts included — is £225. Both include key safety checks, flue checks, gas pressure checks, combustion testing where required and a clear service record.
How often should I service my boiler?
You should service your boiler once a year. An annual boiler service helps keep your boiler safe, efficient and reliable, and most manufacturers require yearly servicing to keep the warranty valid.
What is included in a boiler service?
A boiler service includes checks on the boiler, flue, ventilation, gas pressure, combustion performance, safety devices, seals, controls and visible signs of wear or leaks. The engineer will also explain anything that needs attention.
What’s the difference between a standard and a comprehensive boiler service?
A standard service is the full annual safety and performance check. A comprehensive service adds a full strip-down and internal clean of the boiler, with new seals fitted and the electrodes checked or replaced — worth it for older boilers, boilers that have missed services or ones running rough. We’ll tell you honestly which yours needs.
Are your boiler servicing engineers Gas Safe registered?
Yes. Boiler servicing is carried out by Gas Safe registered engineers. This is important because gas appliances should only be checked, serviced or repaired by a qualified Gas Safe engineer.
How long does a boiler service take?
A standard boiler service usually takes around 45 to 60 minutes, depending on the boiler type, condition, access and whether any issues are found during the inspection.
Do I need a boiler service to keep my warranty valid?
In most cases, yes. Many boiler manufacturers require an annual service by a Gas Safe registered engineer to keep the warranty valid. We provide a service record so you have proof the boiler has been checked.
Can you service all boiler brands?
We service most major domestic boiler brands, including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton, Vokèra and Alpha. Tell us your boiler make and model when booking.
Do landlords need boiler servicing as well as a gas safety certificate?
A landlord gas safety certificate checks gas safety at the property, but it is not the same as a full boiler service. Many landlords book both together to keep the boiler safe, reliable and properly maintained.
