What's different about Bristol
The South West has a high share of off-gas and oil-heated homes, which is where a heat pump usually makes the strongest running-cost case. Solid stone walls are common, so insulation is often assessed first.
Installers quoting in Bristol usually cover Bath, Weston-super-Mare, Thornbury, Clevedon and Yate. If an installer doesn't routinely work in your postcode, travel and return-visit costs tend to be built into the price — which is exactly why we match on postcode first.
What moves your quote up or down
- Heat loss calculation — A room-by-room heat loss survey sets the unit size. An oversized unit costs more to buy and more to run.
- Radiators and pipework — Heat pumps run at lower flow temperatures, so some radiators may need to be larger.
- Hot water cylinder — Most homes need a new cylinder, plus somewhere to put it.
- Insulation — Loft and cavity work is often recommended first, and changes both the unit size and running cost.
