Why service matters
A service isn’t just a box-ticking exercise. It keeps your manufacturer warranty valid, catches small faults before they become breakdowns, and keeps your boiler running at its most efficient — which shows up on your energy bill.
What’s included
Gas tightness, ventilation and flue all tested to Gas Safe standard.
Combustion and burner performance tested and adjusted if needed.
Casing, seals and pipework checked for wear or corrosion.
Small tweaks made on the day where it’s safe to do so.
Logged and given to you — proof for your warranty or CP12.
If something needs attention, we’ll tell you and quote it separately.

Pick a slot that works for you — no need to wait in all day.
Usually 45 minutes to an hour, start to finish.
You'll get a written record and honest advice on anything worth watching.

Have used Gavin at GH Heating for a few years for our boiler. Earlier this week I had a problem with our water supply upstairs and rang GH on the off chance they could help. Gavin arrived first thing next morning and identified the problem, went for a new part and fitted and tested system before lunchtime that day. Excellent service as always and would not hesitate to recommend him and his company.Read full review
Gavin and his team are very professional from start to finish. Excellent installation of our boiler which had to be relocated within our property which was quite challenging but this was no problem for them , I would highly recommend GH Heating services if you want a stress free competent experience from a great companyRead full review
Gavin has been servicing my gas boiler since he had to replace it's 38 year old predecessor, after I called him out to attempt to get it working. I now have to protect the 10 year warranty with an annual service including a filter change. Gavin offers a very reliable service, with a reminder and invitation to book a time slot to maintain the service history. I am always happy with the service offered and Gavin is a very friendly engineer.Read full review
Is it overdue?
Most manufacturers require an annual service to keep the warranty valid.
Should always burn blue — get this checked promptly.
Banging, kettling or an unusual smell are worth investigating.
Often a sign something needs adjusting or replacing.
Common questions
Once a year, in most cases — check your manual, but annual servicing is the standard requirement to keep a manufacturer warranty valid.
Usually 45 minutes to an hour, depending on the boiler and how easy it is to access.
We’ll tell you and quote it separately before doing any extra work — a service is a check, not an invitation to add costs on the day.
