Upfront cost — no obligation An annual boiler service keeps your boiler running safely and efficiently — and on most newer boilers it’s a condition of keeping the manufacturer’s warranty valid. Gas First services boilers of every make right across Dagenham, from a local base, including the Becontree estate and the RM8, RM9 and RM10 postcodes. It’s a small yearly job that prevents expensive breakdowns and keeps your heating reliable through the winter.
Why service your boiler every year in Dagenham
A yearly service does three things: it keeps your boiler safe (catching issues like poor combustion or a blocked condensate before they become dangerous), it keeps it efficient (a clean, well-tuned boiler uses less gas), and on most modern boilers it keeps the manufacturer’s warranty valid — miss a service and you can void years of cover. A lot of Dagenham’s housing is older Becontree stock where reliable heating really matters through winter, and a serviced boiler is far less likely to let you down when you need it most. We service all makes, from a local base, at a time that suits you.

What's included in a Gas First boiler service
Our service is a proper one, not a quick glance. We carry out a full inspection and flue gas analysis to check the boiler is burning safely and efficiently, clean the magnetic filter, clear and check the condensate trap, check and recharge the expansion vessel where needed, and inspect seals, controls and safety devices. We run a gas soundness check and confirm the boiler is operating to the manufacturer’s spec. If we spot anything that needs attention we explain it clearly and tell you the cost before doing any further work — you’re never caught out.
Keeping your warranty valid, from a local team
If you’ve had a new boiler fitted, the manufacturer almost always requires a documented annual service by a Gas Safe registered engineer to keep the warranty in force — so an annual service isn’t just good practice, it protects the cover you’ve paid for. We service every make and keep the paperwork right. We’re Gas Safe registered (587401) and fully insured, and being based locally in Dagenham means an appointment that fits around you. Landlords can combine a service with a landlord gas safety certificate (CP12) in the same visit.

A recent boiler service in Dagenham
A homeowner in Dagenham had recently had a new Vaillant Pure combi boiler installed and called us to carry out its first annual service — needed to keep the manufacturer’s warranty valid. Everything was in good order, exactly as you’d want on a newer boiler. We cleaned the magnetic filter, cleared and checked the condensate trap, recharged the expansion vessel, and carried out our full flue gas analysis and safety checks. A quick, clean service that kept the boiler running at its best and the warranty firmly in place — a good example of why that yearly visit is well worth booking.

“Highly recommend for any boiler issues. We used them for our annual service and to fix several other issues. The engineer was incredibly thorough, he even took the time to overhaul the system. It's rare to find an engineer who is this transparent and knowledgeable. Fair pricing and excellent communication throughout. Will definitely use them again next year and any time we need them.”
