Boiler service in Harrow
- Semis in Metroland now on a second or third heating system, with pipes left over from each
- Loft conversions built on top of a system nobody resized to suit them
- Old controls that no longer work the way the owner believes
Loft conversions in Harrow’s 1930s semis often moved the boiler too, either into the eaves cupboard of the new room or into what is left of the roof space. An eaves boiler can be serviced, but the engineer needs the cupboard emptied and enough room to take the case off and put test equipment into the flue. Where the flue goes straight up through the roof rather than out through a wall, the terminal can only be checked from inside and by eye from the ground, so any damage to it needs a separate visit with ladders or scaffolding. Houses still on a cylinder have a pump, a motorised valve and a programmer sitting outside the boiler, and those are part of what gets looked at, because a stuck valve can look like a boiler fault. Most roads here have driveways or easy kerbside parking, which keeps the visit to the time the work actually takes.

Questions we often get
Do you work in Harrow?
We do. Harrow falls within Harrow, covering the HA1, HA2, HA3, HA5 postcodes, and our engineers are out across Greater London from our Fulham office every day.
We are on our third boiler. Does the old pipework make any difference?
It might. Each new installation tends to leave behind dead legs, redundant pipes and valves no one has touched for twenty years. On its own none of that is dangerous, but it hampers circulation and slows down any diagnosis. A service is a sensible time to record what is really there.
Our boiler is in the eaves cupboard of the loft conversion. What do I need to clear?
Take out everything stored in front of and around it, including boxes resting against the pipework. The engineer needs to kneel in front of it, get the cover off and put a probe in the flue. If the cupboard door is small or the boiler sits a long way back, let us know when you book so we allow the time. If the installer fitted vents to the cupboard, keep those clear too.
How much will it cost?
Before an engineer starts, you are given a price for the job. Should something hidden in a wall change what is needed, we stop and discuss it with you first, instead of pressing on and sending the bill later.
