We cover Stowmarket and nearby Ipswich, Bury St Edmunds and the rest of Suffolk. A heat pump is a whole-system change, so the survey looks at radiators, pipework, the hot water cylinder and the best spot for the outdoor unit.

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

How long is the heating season in Stowmarket?
Stowmarket has about 7 hours 42 minutes of daylight at midwinter and 16 hours 46 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.
Heat pumps in Stowmarket: questions
Can you service a heat pump in Stowmarket that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Stowmarket, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Stowmarket 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 Stowmarket home.
Where would the outdoor unit go on a Stowmarket 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 Stowmarket home.
Do I need new radiators for a heat pump in Stowmarket?
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 Stowmarket home gives a room-by-room list.
