Why Your Boiler Needs an Annual Service (And What Happens If You Skip It)

Every autumn our phones light up with the same story: a boiler that's been 'fine for years' suddenly dies on the coldest night. In almost every case, the warning signs were there months earlier — and an annual service would have caught them for £85.99.

So what does a proper service involve? We strip the boiler down and clean the burner and heat exchanger, check the flue for safe operation, run a flue gas analysis to confirm clean combustion, test gas pressure and tightness, inspect seals and the condensate trap, and check your system pressure and expansion vessel. It's an 18-point check, and it takes about an hour.

There's a money angle too. A boiler burning cleanly uses less gas — a sooty heat exchanger can quietly add 10% to your bills. Most manufacturers also require annual servicing to keep your warranty valid. Skip the service and a failed part that should have been free suddenly isn't.

And the safety angle is the one that matters most. A faulty boiler can produce carbon monoxide — colourless, odourless, and dangerous. A service includes the combustion checks that catch it. If you remember one thing: book the service before winter, not during it.
