We cover Carlisle and nearby Penrith, Keswick and the rest of Cumbria. A heat pump is a whole-system change, so the survey looks at radiators, pipework, the hot water cylinder and the best spot for the outdoor unit.

Grants and rules for heat pumps in England
Homes in Carlisle can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Heat pumps in Carlisle: questions
How long does a heat pump survey take in Carlisle?
A home survey in Carlisle usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How long does installation take in Carlisle?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Carlisle home states the expected time.

Yes. We arrange surveys and installation in Penrith, which is about 17 miles south-east of Carlisle, and across Cumbria.
Can you service a heat pump in Carlisle that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Carlisle, whoever fitted them. Tell us the make and model when you book.
