What to know about heat loss surveys in East Grinstead
Homes around East Grinstead range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Design outdoor temperatures for East Grinstead and the wider West Sussex come from local cold-weather data, not a national average. The survey in East Grinstead includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
A surveyor visits your East Grinstead 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 East Grinstead 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.
Guide prices for heat loss surveys in East Grinstead
The ranges below are typical installed prices for homes in West Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in East Grinstead 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 | £160–£420 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in East Grinstead?
East Grinstead sees roughly 7 hours 53 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 East Grinstead: questions
Do you cover Crawley as well as East Grinstead?
Yes. We arrange surveys and installation in Crawley, which is about 8 miles west of East Grinstead, and across West Sussex.
How long does a heat pump survey take in East Grinstead?
A home survey in East Grinstead 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.
Do I need new radiators for a heat pump in East Grinstead?
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 East Grinstead home gives a room-by-room list.
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.
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.
