Before you book: air source heat pump installation in Horncastle
Homes around Horncastle range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Installers working in Horncastle plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Horncastle 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.
- Owners who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
What's included
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- Outdoor unit, hot water cylinder and weather compensation controls
- System design, unit sizing and a written quote
- Boiler Upgrade Scheme application in England and Wales where eligible
For older properties in Horncastle, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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 Horncastle quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Designing for Horncastle's winters
Horncastle has about 7 hours 31 minutes of daylight at midwinter and 16 hours 59 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Air source heat pump installation in Horncastle: questions
What size heat pump does a Horncastle 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 Horncastle home.
Where would the outdoor unit go on a Horncastle 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 Horncastle home.
Can you service a heat pump in Horncastle that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Horncastle, whoever fitted them. Tell us the make and model when you book.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
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.
