What to know about heat loss surveys in Petersfield
Most homes can run on a heat pump if the system is designed properly, and Petersfield is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners in Petersfield thinking about insulation work can use the survey to see how it would change their heat pump size. For Petersfield homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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.
- Homes with an existing heat pump that seems undersized or expensive to run
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
What's included
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
Houses in Petersfield built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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 Petersfield quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
Heat loss survey prices in Petersfield
Guide prices for Petersfield 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 Petersfield
On the shortest day Petersfield gets about 7 hours 55 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat loss surveys in Petersfield: questions
Can you service a heat pump in Petersfield that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Petersfield, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Petersfield?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Petersfield home states the expected time.
Do I need new radiators for a heat pump in Petersfield?
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 Petersfield home gives a room-by-room list.
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.
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.
