What to know about air source heat pump installation in Truro
Homes around Truro range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
In Truro, cylinder space is planned with you, often in an airing cupboard, utility room or garage. For older properties in Truro, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Households with room for a hot water cylinder
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
What's included
- Boiler Upgrade Scheme application in England and Wales where eligible
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
- Removal of the old boiler or heaters
- Radiator and pipework changes where the design needs them
Many homes in Truro have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Grants and rules for heat pumps in England
Homes in Truro 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.

Air source heat pump installation in Truro: questions
Do I need new radiators for a heat pump in Truro?
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 Truro home gives a room-by-room list.
Can you service a heat pump in Truro that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Truro, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Truro?
A home survey in Truro 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.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
