Grants and rules for heat pumps in England
Homes in St Albans 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.

Short winter days in St Albans and what they mean
St Albans has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 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 St Albans: questions
What size heat pump does a St Albans 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 St Albans home.
Do you cover Radlett as well as St Albans?
Yes. We arrange surveys and installation in Radlett, which is about 4 miles south of St Albans, and across Hertfordshire.
How soon can you survey a home in St Albans?
Survey dates depend on how busy installers are in Hertfordshire. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in St Albans that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in St Albans, whoever fitted them. Tell us the make and model when you book.
