Burgess Hill grew fast through the second half of the twentieth century and it shows in the housing. Large tracts of similar-age property means large tracts of similar-age heating systems, all reaching the end of their working lives at roughly the same time.
Local knowledge
Predominantly post-war and later, with substantial 1960s through 1980s estate development and continuing modern building on the edges. Older villages nearby at Ditchling and Hurstpierpoint add genuine period stock. The estate housing typically has boilers on their second or third replacement and original pipework underneath that has never been properly cleaned.
Because so much Burgess Hill housing went up in the same era, we see the same faults in waves. A system that is thirty years old with original steel radiators and no inhibitor history is a magnetite problem waiting to happen, and fitting a new boiler onto it without a proper flush is the fastest way to void a manufacturer warranty. We check system water condition here as standard before quoting a boiler.
Burgess Hill’s water comes from chalk aquifers, like much of the South Downs area, and it is very hard, at around 280 parts per million. Heating that water drops the hardness out as scale, and we find the results here regularly: blocked heat exchangers, scaled-up immersion heaters, and combis whose hot water side has furred up until it cannot hold a steady temperature. A water softener or scale reducer on the incoming main, and an annual boiler service, are the cheapest defence. Where scale and sludge have already built up in the radiators, a powerflush clears the heating side.
If the hot water is weak in a Burgess Hill house, there are three usual suspects.
Each has a different fix: descaling or replacing the plate heat exchanger, converting to a combi or an unvented cylinder, or replacing the worst pipe runs. We work out which it is before you spend anything. Our guide to low water pressure covers the checks you can do first.
The newer developments on the edges of town have mains pressure systems, with combis or unvented cylinders, that perform well and are more sensitive to scale than the older gravity systems on the estates. A combi’s plate heat exchanger has narrow waterways that fur up, and an unvented cylinder’s coil, immersion and relief valves all collect scale. Keeping to the annual service protects the manufacturer warranty, and the cylinder’s safety checks need a G3 qualified engineer, which we are.
Ditchling and Hurstpierpoint add older village property to the mix. Converting a period cottage from tank-fed hot water, or finding a route for a new flue through an old wall, is a different job from an estate boiler swap, and we survey it in person before quoting. See boiler installation.
Leave the property, do not touch any switches, then call the National Gas Emergency Service on 0800 111 999. Once it is made safe, call us and we will handle the repair and recommissioning as Gas Safe registered engineers.

Reviews
Excellent job. Nice guy. totally reliable. Thank you!
Had an emergency water leak, they responded immediately. Easily the best plumbing and heating company I've used in the Crawley. very fairly priced
It was 11pm at night last night and we had water gushing into our kitchen due to the bad weather. So we called 'Mend your home' and they got to us within minutes to assess the situation promptly. The guy was…
Questions
Usually one of three things: scale from the very hard local water narrowing the hot water side of a combi or the pipework, an ageing gravity-fed system of the kind still common on the 1970s and 1980s estates, where pressure depends on the height of the loft tank, or a partly closed stopcock. We test which it is before recommending a descale, a repair or an upgrade to an unvented cylinder.
Very hard, typically around 280 parts per million, because it comes from chalk aquifers. It scales boiler heat exchangers and immersion heaters, and left alone it is a major cause of heating inefficiency and early boiler breakdowns. A water softener or scale reducer on the incoming main, plus an annual service, is the practical answer, and it costs far less than the repairs it prevents.
Yes. We cover Burgess Hill and the RH15 area, plus Wivelsfield, Keymer, Hassocks, Hurstpierpoint and Ditchling. It is around 30 minutes south of our Crawley base. In an emergency, call and we will give you a straight answer on timing based on what is already booked, and talk you through isolating the water while we get there.
On a thirty-year-old estate system with original radiators and no inhibitor history, usually yes. We test the system water first so you only pay for a flush if it is needed. A powerflush is from £400, typically £400 to £780 for an average three-bedroom house, and skipping it when the water is dirty can void the new boiler's manufacturer warranty.
From £105, at a fixed price. Our Gas Safe registered engineers check the combustion, the safety devices and the hot water side, which matters in a hard water town. Annual servicing is a condition of most manufacturer warranties, and in newer homes with an unvented cylinder the cylinder needs its own yearly check by a G3 qualified engineer. Landlords save by combining the service with a CP12.
