Heat loss survey for Basingstoke homes
A heat pump suits most Basingstoke homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Houses in Basingstoke built in different eras can need very different heat pump sizes, which is why each is calculated room by room. Design outdoor temperatures for Basingstoke and the wider Hampshire come from local cold-weather data, not a national average.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Basingstoke home to measure each room, window and wall before any heat pump is sized.
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 Basingstoke 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.
Guide prices for heat loss surveys in Basingstoke
Guide prices for Basingstoke and the rest of Hampshire are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£410 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Winter daylight and heating in Basingstoke
Basingstoke sees roughly 7 hours 52 minutes of daylight in late December against 16 hours 36 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat loss surveys in Basingstoke: questions
How long does installation take in Basingstoke?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Basingstoke home states the expected time.
Where would the outdoor unit go on a Basingstoke 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 Basingstoke home.
Do I need new radiators for a heat pump in Basingstoke?
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 Basingstoke home gives a room-by-room list.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
