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 Southwold 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.
Heat pump guide prices in Southwold
The ranges below are typical installed prices for homes in Suffolk, including VAT. A survey sets the exact figure, because two similar-looking houses in Southwold can need quite different radiators and pipework.

Winter daylight and heating in Southwold
Southwold has about 7 hours 41 minutes of daylight at midwinter and 16 hours 48 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 Southwold: questions
Can you service a heat pump in Southwold that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Southwold, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Southwold 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 Southwold home.
Do I need new radiators for a heat pump in Southwold?
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 Southwold home gives a room-by-room list.
How soon can you survey a home in Southwold?
Survey dates depend on how busy installers are in Suffolk. We offer the next available dates when you enquire and confirm them in writing.
