Boiler Servicing, Repair and Installation in Coulsdon

Coulsdon is two towns as far as heating is concerned. There is the brand new housing on the old Cane Hill Hospital site, where the boilers are still inside their manufacturer warranty and the job is keeping that warranty alive. Then there is Old Coulsdon up on the ridge, where the housing is largely nineteen thirties and the job is the opposite one entirely.

What we do in Coulsdon

Housing in Coulsdon, and what it means for your heating

Cane Hill Park added several hundred new homes off Coulsdon South, and those properties came with modern condensing boilers, sealed systems and smart controls already fitted. Old Coulsdon and the streets running up towards Farthing Downs are a different era: interwar semis, solid floors in places, and a fair number of systems that have been extended piecemeal as families added a downstairs loo or a back extension.

  • On the newer Cane Hill properties the critical thing is the annual service. Nearly every manufacturer voids the warranty after a missed year, and on a boiler that is only three or four years old that is an expensive thing to lose over a job that takes an hour.
  • We email the service report the same day, which is the document the manufacturer asks for if you ever need to claim. Keep them together in one folder from the first year.
  • In Old Coulsdon the recurring find is a system that has been added to without ever being rebalanced. Two extra radiators on a circuit that was already at capacity does not warm the extension, it cools the rest of the house.

The work we do most in Coulsdon

Split fairly evenly between warranty servicing on the newer estates and heating repairs on the older housing. On the new builds it is mostly annual services, the occasional commissioning fault that nobody spotted on handover, and setting up smart controls properly so the system actually modulates instead of firing flat out and cycling. Up in Old Coulsdon it is more often radiators that never get hot, pipework that was buried under a solid floor by somebody in a hurry, and boilers coming to the end of a long life. The two halves of the town rarely need the same visit.

Questions we get asked in Coulsdon

My house on Cane Hill Park is new, does it still need a service?

Yes, and more urgently than an old one. Almost every manufacturer warranty requires an annual service by a Gas Safe registered engineer, and missing a single year can void cover on a boiler that has barely been used. It is the cheapest insurance in the house.

Why does my extension never get warm in Old Coulsdon?

Usually because radiators were added to a circuit that was already at its limit, and nobody rebalanced the system afterwards. The fix is sometimes just balancing, and sometimes a genuine capacity problem that needs the pipework or the boiler looking at. We test before we quote either.

Do you cover both Coulsdon and Old Coulsdon?

Both, along with the streets up towards Farthing Downs and Chipstead Valley Road. It is all inside the standard callout area at the same prices.

After being messed around by a different company, we were recommended Go Fix and we couldn't be happier with the work they have done. Friendly, clean and they turned up everyday on time which seems hard to come by these days.
