Before you book: heat loss surveys in Frome
Most homes can run on a heat pump if the system is designed properly, and Frome is no different. The key is matching the heat pump and radiators to the home's heat loss.
Design outdoor temperatures for Frome and the wider Somerset come from local cold-weather data, not a national average. Houses in Frome built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Self-builders and architects who need emitter and system sizes early
What's included
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
The survey in Frome includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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 Frome 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 Frome
These are guide prices for Somerset, 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 | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Frome's winters
Frome sees roughly 7 hours 52 minutes of daylight in late December against 16 hours 35 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.
What happens after you enquire in Frome?
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Frome home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Frome: questions
Can you service a heat pump in Frome that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Frome, whoever fitted them. Tell us the make and model when you book.
Do you cover Warminster as well as Frome?
Yes. We arrange surveys and installation in Warminster, which is about 6 miles east of Frome, and across Somerset.
How long does installation take in Frome?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Frome home states the expected time.
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.
