Boiler installers and housing in the South West

The South West mixes gas towns such as Bristol and Exeter with rural villages that run on oil or LPG. Where gas is available a combi is the straightforward choice, and installers in the region fit the main makes in similar numbers.

Across the South West, many homes are older stone or rendered cottages and farmhouses, some off the gas grid, so the choice between gas, oil, LPG and electric is a real one here. Check what fuel is available at the property before you compare boiler types.

South West conversions often involve older cottages and farmhouses where moving a boiler means a longer gas or oil run and a flue through thick stone walls. Allow for extra days and ask the installer to survey the route before quoting.

Across the South West, many boilers sit in older stone houses with long pipe runs, so a service may take longer and a repair may need a part that has to be ordered. Rural homes on oil or LPG need an engineer qualified for that fuel, so say which you have when you book.

The South West has one of the highest proportions of solid-wall housing in England. Stone is the norm across Devon and Cornwall, cob survives in quantity in Devon, and Bath and the Cotswolds are built in limestone that carries its own conservation rules. Bristol adds a large Victorian terraced belt. Much of this stock has no cavity at all, and lime rather than cement is often the correct material for repairs.

Planning and building rules in the South West

Dartmoor, Exmoor and a string of National Landscapes cover much of the region, and Bath is a UNESCO World Heritage Site with correspondingly strict controls. Cornwall and Devon have high concentrations of listed buildings, where like-for-like repair in traditional materials is usually the only route.

The weather

Mild and wet, with the wettest ground on Dartmoor and Exmoor and rainfall well above the English average through the west of the region. The long coastline means salt exposure is a routine consideration rather than an edge case: fixings, flashings and renders all weather faster within a mile or so of the sea, and specifications should account for it.
