What's different about Swansea
Wales uses the Boiler Upgrade Scheme like England, and has a high share of off-gas and oil-heated rural homes — the situation where a heat pump usually beats the incumbent system on running cost. Solid stone walls are common, so insulation is often assessed first.
Installers quoting in Swansea usually cover Neath, Port Talbot, Llanelli, Gorseinon and Mumbles. 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.
