New Boiler Bournemouth & Poole: Gas Safe Installers

Over a third of BCP households live in a detached house, against fewer than one in ten in a terrace. Bigger homes with two or more bathrooms often need stored hot water, so a straight swap to a combi isn't always right.

At the other end, flats make up about 37% of homes, and for most of those a compact combi is the obvious choice.

Sizing it right

Oversized boilers short-cycle and waste gas. Ask the installer to work out the heat loss rather than just matching the old boiler's output, which was often oversized.

For a detached house with two bathrooms, a system boiler with an unvented cylinder runs showers at the same time. For a bungalow with one bathroom, a combi is usually enough.

Mains pressure matters for a combi or an unvented cylinder. Ask the installer to measure the flow at the kitchen tap before recommending either.

Water and protection

Bournemouth Water rates its supply as moderately hard, so scale is less of a worry than further east. A magnetic filter, a system flush and inhibitor still matter; manufacturers usually require them for full warranty.

What a good quote includes

Boiler, flue, controls, flush, filter, removal of the old boiler, and Gas Safe notification leading to a Building Regulations certificate. Our new boiler cost guide gives national ranges to check prices against.

Boilers for BCP homes

Interwar and post-war semis and detached houses

Detached houses with a cylinder already in place are good candidates for a system boiler, or for a heat pump if you're open to one.

Flats in converted villas and purpose-built blocks

A combi in the same kitchen cupboard is usually cheapest. Check the lease before moving the flue.

Bungalows across the suburbs and Christchurch

Bungalows with the cylinder in a hall cupboard can go either way. A combi frees space; keeping the cylinder makes a later heat pump easier.

Areas covered

Engineers who cover Bournemouth work across areas including Boscombe, Southbourne, Westbourne, Winton, Charminster, Kinson, Moordown, Pokesdown, Christchurch and Poole.

Questions people in Bournemouth ask

Should I consider a heat pump instead?

Detached homes and bungalows with gardens are often good candidates. With £7,500 off through the Boiler Upgrade Scheme, a heat pump quote alongside your boiler quotes is worth having for a BCP home with outdoor space.

How long does a swap take in a bungalow?

A combi for combi swap is usually a day. Converting from a regular boiler with loft tanks to a combi takes longer, because the tanks and old pipework come out.
