Air source heat pump installation for Windermere homes
In Windermere, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Terraced streets in Windermere often mean a compact unit position at the rear, so siting and sound levels are checked carefully. For older properties in Windermere, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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.
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- Free home survey and room-by-room heat loss calculation
- Radiator and pipework changes where the design needs them
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
Installers working in Windermere plan the order of work so heating and hot water are off for as short a time as practical.
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 Windermere 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.
Air source heat pump installation prices in Windermere
These are guide prices for Cumbria, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

Winter daylight and heating in Windermere
Windermere sees roughly 7 hours 18 minutes of daylight in December and 17 hours 14 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.

Air source heat pump installation in Windermere: questions
How soon can you survey a home in Windermere?
Survey dates depend on how busy installers are in Cumbria. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Windermere?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Windermere home gives a room-by-room list.
Do you cover Kendal as well as Windermere?
Yes. We arrange surveys and installation in Kendal, which is about 7 miles south-east of Windermere, and across Cumbria.
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.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
