Heat loss survey for Okehampton homes
Homes around Okehampton range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For Okehampton homes with extensions or loft conversions, each part of the house is assessed on its own construction. Homeowners in Okehampton 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
- Homes with an existing heat pump that seems undersized or expensive to run
- Landlords comparing properties before deciding where to switch first
What's included
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
Houses in Okehampton 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 Okehampton 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.
What to budget for heat loss surveys in Okehampton
The ranges below are typical installed prices for homes in Devon, including VAT. A survey sets the exact figure, because two similar-looking houses in Okehampton can need quite different radiators and pipework.
| 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.
How long is the heating season in Okehampton?
On the shortest day Okehampton gets about 7 hours 57 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.

- We commission the heat pump, show you the controls and register the installation.
Heat loss surveys in Okehampton: questions
Do I need new radiators for a heat pump in Okehampton?
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 Okehampton home gives a room-by-room list.
How long does installation take in Okehampton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Okehampton home states the expected time.
Can you service a heat pump in Okehampton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Okehampton, whoever fitted them. Tell us the make and model when you book.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
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.
