What to know about air source heat pump installation in Keswick
Most homes can run on a heat pump if the system is designed properly, and Keswick is no different. The key is matching the heat pump and radiators to the home's heat loss.
For older properties in Keswick, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Terraced streets in Keswick often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Households with room for a hot water cylinder
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it

Homeowners across Cumbria can arrange a survey in Keswick for a room-by-room design and a written quote before committing to anything.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Keswick quote.
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.
Guide prices for air source heat pump installation in Keswick
The ranges below are typical installed prices for homes in Cumbria, including VAT. A survey sets the exact figure, because two similar-looking houses in Keswick can need quite different radiators and pipework.

Short winter days in Keswick and what they mean
On the shortest day Keswick gets only about 7 hours 15 minutes of daylight and the noon sun sits around 12° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.
How installation works in Keswick
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Keswick home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Keswick: questions
What size heat pump does a Keswick home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Keswick home.
Do you cover Cockermouth as well as Keswick?
Yes. We arrange surveys and installation in Cockermouth, which is about 10 miles north-west of Keswick, and across Cumbria.
Where would the outdoor unit go on a Keswick house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Keswick home.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
