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.
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.

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.

How soon can you survey a home in Horncastle?
Survey dates depend on how busy installers are in Lincolnshire. We offer the next available dates when you enquire and confirm them in writing.

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.
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.
How long does a heat pump survey take in Horncastle?
A home survey in Horncastle 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.
