Home Boiler servicing Bristol

Boiler service in Bristol

One Bristol household in ten lives in a flat carved out of an older house, and those boilers have their own quirks. We put you in touch with Gas Safe registered engineers who cover your BS postcode.

The 2021 Census found 10.2% of Bristol households living in a converted or shared house, a high share for an English city. Clifton, Redland, Cotham and Bishopston are full of Georgian and Victorian houses split into two, three or four flats, each with its own small combi tucked into a kitchen or hall cupboard.

In those flats, the boiler is usually easy to reach. The flue often is not. It may run horizontally through a ceiling void or up through a shared wall, and a full service should include checking the flue along its length.

Flues in converted buildings

If your flue runs through a void, building rules since 2011 have required inspection hatches so it can be checked. If the engineer cannot see the flue, they may classify the installation as at risk. Find out where the hatches are before the visit, and if there are none, ask the engineer what access is needed.

Tell the engineer which flue terminal on the outside wall belongs to your boiler. In a building with several flats, terminals can sit close together.

Scale in Bristol water

Bristol Water describes all its supply as moderately hard to very hard. On a combi, ask the engineer to check how steady the hot water temperature is and whether a scale reducer is fitted on the incoming main. Scale is easier to deal with early.

If you let the flat

About a quarter of Bristol households rent privately. Landlords must have all gas appliances and flues checked by a Gas Safe engineer every 12 months, give the record to tenants and keep it for two years. Ask for a full service at the same visit so the boiler is maintained, not just certified.

Tenants do not book the check themselves, but should give access and ask for a copy if they have not received one.

Servicing across Bristol homes

Victorian terraces on the city's hills

Terraces in Bedminster, Southville and Easton often have a combi in the back kitchen or the loft. Steep streets and narrow fronts mean parking can be tight, so tell the engineer about access.

Flats in converted Georgian and Victorian houses

Clear the boiler cupboard and know where any flue hatches are. If the building has a shared gas meter cupboard, check the engineer can get in.

Interwar and post-war semis on the outskirts

Homes in Fishponds, Horfield and Kingswood often still have a cylinder. Ask for its thermostat and valves to be checked as well as the boiler.

Areas covered

Engineers who cover Bristol work across areas including Clifton, Bedminster, Southville, Bishopston, Redland, Easton, Fishponds, Horfield, Kingswood and Keynsham.

Questions people in Bristol ask

Does a flat boiler need servicing as often as a house boiler?

Yes, once a year. Small combis in flats work hard because they provide all the hot water on demand.
