Before you book: heat loss surveys in Haslemere
Most homes can run on a heat pump if the system is designed properly, and Haslemere is no different. The key is matching the heat pump and radiators to the home's heat loss.
Houses in Haslemere built in different eras can need very different heat pump sizes, which is why each is calculated room by room. Homeowners in Haslemere thinking about insulation work can use the survey to see how it would change their heat pump size.
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.
- Anyone getting a heat pump quote, as the first step
- Landlords comparing properties before deciding where to switch first
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Recommended heat pump size and design flow temperature
- Outdoor unit siting options and noise check
For Haslemere homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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 Haslemere 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.
What to budget for heat loss surveys in Haslemere
These are guide prices for Surrey, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £160–£430 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Haslemere's winters
Haslemere sees roughly 7 hours 54 minutes of daylight in late December against 16 hours 34 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 Haslemere: questions
Can you service a heat pump in Haslemere that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Haslemere, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Haslemere?
A home survey in Haslemere 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.
Where would the outdoor unit go on a Haslemere 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 Haslemere home.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
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.
