Before you book: heat loss surveys in Gloucester
Homes around Gloucester range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For Gloucester homes with extensions or loft conversions, each part of the house is assessed on its own construction. Design outdoor temperatures for Gloucester and the wider Gloucestershire come from local cold-weather data, not a national average.
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
- Self-builders and architects who need emitter and system sizes early
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
The survey in Gloucester includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Gloucester 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.
What to budget for heat loss surveys in Gloucester
These are guide prices for Gloucestershire, 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.
Winter daylight and heating in Gloucester
Gloucester has about 7 hours 46 minutes of daylight at midwinter and 16 hours 42 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 Gloucester: questions
How long does installation take in Gloucester?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Gloucester home states the expected time.
What size heat pump does a Gloucester 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 Gloucester home.
How long does a heat pump survey take in Gloucester?
A home survey in Gloucester 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.
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.
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.
