Heat loss survey in Great Barr: what to expect
Homes around Great Barr range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Houses in Great Barr built in different eras can need very different heat pump sizes, which is why each is calculated room by room. For Great Barr 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.
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
- Room-by-room heat loss calculation using the MCS method
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
A surveyor visits your Great Barr home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
Homes in Great Barr 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Heat loss survey prices in Great Barr
The ranges below are typical installed prices for homes in the West Midlands, including VAT. A survey sets the exact figure, because two similar-looking houses in Great Barr 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 | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Winter daylight and heating in Great Barr
On the shortest day Great Barr gets about 7 hours 38 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat loss surveys in Great Barr: questions
How long does installation take in Great Barr?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Great Barr home states the expected time.
Do I need new radiators for a heat pump in Great Barr?
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 Great Barr home gives a room-by-room list.
What size heat pump does a Great Barr 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 Great Barr home.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
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.
