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 across Upminster and the RM14 postcode, from our Dagenham base — the village, Corbets Tey and Cranham. It’s a small yearly job that prevents expensive breakdowns and keeps your heating reliable.

Why service your

Why service your boiler every year in Upminster

A yearly service does three things: it keeps your boiler safe (catching issues before they become dangerous or expensive), 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 service is also the best time to pick up the small, common wear items that develop on any boiler, and put them right before they turn into a breakdown. We service all makes across RM14, at a time that suits you.

What's included in

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.

A service that catches wear early, from a local team

Going through the whole boiler on a service is how we catch small faults before they leave you cold. We’re Gas Safe registered (587401) and fully insured, we service every make and keep the warranty paperwork right, and our Dagenham base is a short run out to RM14. Landlords can combine a service with a landlord gas safety certificate (CP12) in the same visit.

A recent boiler

A recent boiler service in Upminster

We carried out an annual service on a Vaillant boiler for a customer in Upminster. During the inspection we found the automatic air vent (AAV) was leaking — a common wear item across all makes of boiler as the seals age. We replaced the AAV and then completed the full service: flue gas analysis, cleaning the condensate trap and the magnetic filter, and our full safety checks. The boiler came away serviced, leak-free and running efficiently — a good example of how a proper service catches and fixes the small things before they become a problem.
