A thorough once-a-year inspection and tune-up by Gas Safe registered engineers — the single visit that keeps your manufacturer warranty alive, your gas bills in check and your heating reliable when winter arrives.
What happens
A boiler service is not a quick glance and a sticker. Our Gas Safe registered engineers work through the checks the manufacturer specifies for your particular model, measuring how the boiler is actually burning rather than assuming it's fine because it fires up.
The core of the visit is a combustion and flue gas analysis: an electronic analyser samples the flue gases to confirm the burner is running clean, safe and efficient, and the readings are recorded on your service sheet. The engineer then inspects the components that fail most often — heat exchanger, burner, seals and safety devices — and checks that system pressure, the expansion vessel and the heating controls are all doing their jobs.
Anything drifting out of tolerance is adjusted on the spot, and anything genuinely wrong is explained to you with a fixed quote before it's touched. For most homes the visit takes somewhere between 45 minutes and an hour.
Why it matters
Most manufacturer warranties — including the long 7- and 10-year ones — are conditional on an annual service by a Gas Safe registered engineer. A missed year can void the years that remain. We complete the service record on every visit so your warranty file is always claim-ready.
A burner drifting out of adjustment or a scaling heat exchanger makes the boiler work harder for the same heat. Servicing restores efficiency, so the boiler burns less gas to keep the house at the same temperature — quietly repaying the cost of the visit.
If you let the property, combine the service with the annual CP12 gas safety certificate: one engineer, one access arrangement with the tenant, both jobs done. It's the tidiest way to keep the legal and the practical in step.
Warranties don't lapse because owners stop caring — they lapse because a date slips by. We log your next service date and remind you before it's due, so the record stays unbroken for as long as you own the boiler.
Safety, too. The service confirms the boiler is burning cleanly and that the flue and seals are intact — the same defects that, left alone, can lead to carbon monoxide escaping into the home. If the property doesn't yet have an audible CO alarm near the boiler, we can fit one during the same visit — see carbon monoxide alarms.
How it works
Send the make and model (a photo is fine) and the property postcode. We reply with a fixed quote, usually the same working day.
The engineer needs access to the boiler, its controls and the flue. For tenanted properties we can arrange access with the tenant directly.
The completed service record — with the analyser readings — goes into your warranty file, and to your agent if you'd like a copy sent on.
We remind you before the next service falls due, so the history stays unbroken without you keeping a diary.
If the service uncovers a fault, you'll get a fixed quote for the boiler repair before any work starts — and if the boiler is genuinely near the end of its life, we'll say so and quote a new boiler installation as a comparison, so you can weigh the numbers rather than take anyone's word for it. See all our boiler services, or get in touch to book.
Common questions
It depends on the boiler type and the property's location — a modern combi is quicker to service than an older floor-standing or back boiler unit. Send the boiler make and your postcode via WhatsApp or the quote form and we'll reply with a fixed quote, usually the same working day.
Late spring to early autumn, when the heating is off anyway and any fault found can be fixed without leaving you cold. If the boiler is under warranty, book before each anniversary of the installation date so the service history has no gaps.
Almost every manufacturer warranty requires an annual service by a Gas Safe registered engineer, evidenced by a completed service record. Miss a year and the remaining warranty can be refused when you come to claim — so keep the record safe and let our annual reminders do the remembering.
No. The CP12 gas safety certificate is a legal inspection covering every gas appliance in a rented property, while a service is preventative maintenance of the boiler itself. Landlords benefit from both, and we can complete the two in a single visit.
You get a plain-English explanation of what's wrong, how urgent it is, and a fixed quote for the repair before any work goes ahead. Nothing is replaced without your say-so.
