What to know about heat loss surveys in Crowthorne
In Crowthorne, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
For Crowthorne homes with extensions or loft conversions, each part of the house is assessed on its own construction. Design outdoor temperatures for Crowthorne and the wider Berkshire 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.
- Homes with an existing heat pump that seems undersized or expensive to run
- Self-builders and architects who need emitter and system sizes early
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
The survey in Crowthorne 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 Crowthorne 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.
Guide prices for heat loss surveys in Crowthorne
The ranges below are typical installed prices for homes in Berkshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Crowthorne 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.
Winter daylight and heating in Crowthorne
On the shortest day Crowthorne gets about 7 hours 51 minutes of daylight, and the winter sun reaches only around 15° 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.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Crowthorne: questions
Can you service a heat pump in Crowthorne that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Crowthorne, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Crowthorne?
Survey dates depend on how busy installers are in Berkshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Sandhurst as well as Crowthorne?
Yes. We arrange surveys and installation in Sandhurst, which is about 2 miles south of Crowthorne, and across Berkshire.
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.
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.
