Heat loss survey in Dunstable: what to expect
Homes around Dunstable range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Houses in Dunstable built in different eras can need very different heat pump sizes, which is why each is calculated room by room. For Dunstable 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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
What's included
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Dunstable 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 Dunstable 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 costs around Dunstable
These are guide prices for Bedfordshire, 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–£410 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Dunstable?
Dunstable has about 7 hours 46 minutes of daylight at midwinter and 16 hours 43 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat loss surveys in Dunstable: questions
How soon can you survey a home in Dunstable?
Survey dates depend on how busy installers are in Bedfordshire. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Dunstable that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Dunstable, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Dunstable 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 Dunstable home.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
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.
