What to know about heat loss surveys in Glastonbury
Most homes can run on a heat pump if the system is designed properly, and Glastonbury is no different. The key is matching the heat pump and radiators to the home's heat loss.
Design outdoor temperatures for Glastonbury and the wider Somerset come from local cold-weather data, not a national average. For Glastonbury 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
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
A surveyor visits your Glastonbury home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
Homes in Glastonbury can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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 Glastonbury
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.
How long is the heating season in Glastonbury?
Glastonbury 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.
How installation works in Glastonbury
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Glastonbury 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 Glastonbury: questions
What size heat pump does a Glastonbury home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Glastonbury home.
Where would the outdoor unit go on a Glastonbury 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 Glastonbury home.
Can you service a heat pump in Glastonbury that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Glastonbury, whoever fitted them. Tell us the make and model when you book.
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.
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.
