Get your central heating ready before the first cold snap
Updated 1 October 2026 · 2 minute read · From our Gas Safe heating engineers
The week the weather turns is the week everyone in Bridgend searches for a heating engineer near me at once. Most of those calls are problems that were already there in September. An hour this weekend can keep you off that list.
Run it before you need it
Put the heating on for an hour on a mild day, with every thermostatic valve turned up. You are looking for anything that has changed since last winter.
- Walk round every radiator. Cold at the top means air: bleed it. Cold along the bottom means sludge. Cold all over, check the valves are open; thermostatic heads can stick after a summer of not moving.
- Listen to the boiler. Banging or kettling means scale or sludge on the heat exchanger. Worth acting on now rather than in January.
- Watch the pressure gauge. Cold, it should sit roughly between 1 and 1.5 bar. If it climbs well over 2 bar when hot and drops low when cold, the expansion vessel needs looking at.
Outside
- The condensate pipe. Find the plastic pipe that runs from the boiler to a drain. If it is long and exposed, it is the one that will freeze first. Make sure it is lagged and has a steady fall, with no dips.
- Outside taps. If yours has an isolating valve inside, turn it off and drain the tap so it cannot split in a frost.
Book the service early
An annual boiler service is £84, usually takes under an hour, and keeps the manufacturer warranty valid. On a service we take flue and combustion readings with an analyser, check the gas pressure and rate, check the seals and casing, look at the condensate route and its fall, and test every safety device. Anything that needs attention comes with what, why and what it costs.
Booking in the autumn means a choice of dates before the diary fills up.
Brackla, Coity, Broadlands and the rest of town
We cover all of Bridgend from our base in Pencoed, ten minutes away: Brackla, Coity, Litchard, Broadlands, Wildmill and Pen-y-fai, plus Sarn, Aberkenfig and Tondu north of the M4. If the check turns something up, tell us what you found and we will tell you whether it is a quick fix or a visit.

- Cold radiators: how a heating engineer tells bleed, balance and flush apart Where a radiator is cold tells you the fix. Cold at the top, cold at the bottom, or whole rooms never warm: three symptoms, three different jobs, and only one of them needs a powerflush.
- Boiler pressure keeps dropping: how often is too often? Topping up once or twice a year is normal. Weekly is a fault. How to read your pressure gauge, the two usual causes, and why topping up every week costs more than the repair.
- Radiators hot, taps cold: why a combi stops making hot water When a combi boiler heats the radiators but not the taps, the fault is usually one part: the diverter valve. What it does, what to check first, and why it is a repair, not a new boiler.
