Heat loss survey for Heathfield homes
A heat pump suits most Heathfield homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Design outdoor temperatures for Heathfield and the wider East Sussex come from local cold-weather data, not a national average. For Heathfield 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.
- Landlords comparing properties before deciding where to switch first
- 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
What's included
- Radiator schedule with any upgrades needed for each room
- Outdoor unit siting options and noise check
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
Homeowners in Heathfield thinking about insulation work can use the survey to see how it would change their heat pump size.
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 Heathfield 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.

How long is the heating season in Heathfield?
On the shortest day Heathfield 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 Heathfield: questions
Where would the outdoor unit go on a Heathfield 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 Heathfield home.
How long does a heat pump survey take in Heathfield?
A home survey in Heathfield 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 you cover Uckfield as well as Heathfield?
Yes. We arrange surveys and installation in Uckfield, which is about 7 miles west of Heathfield, and across East Sussex.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
