Grants and rules for heat pumps in England
Homes in Daventry 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.

Designing for Daventry's winters
On the shortest day Daventry gets about 7 hours 42 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.
Heat pumps in Daventry: questions
How long does installation take in Daventry?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Daventry home states the expected time.
Do you cover Towcester as well as Daventry?
Yes. We arrange surveys and installation in Towcester, which is about 11 miles south-east of Daventry, and across Northamptonshire.
Where would the outdoor unit go on a Daventry 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 Daventry home.
What size heat pump does a Daventry 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 Daventry home.
