What to know about heat loss surveys in Croydon
In Croydon, 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 Croydon homes with extensions or loft conversions, each part of the house is assessed on its own construction. Homeowners in Croydon thinking about insulation work can use the survey to see how it would change their heat pump size.
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.
- Anyone getting a heat pump quote, as the first step
- 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
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
A surveyor visits your Croydon home to measure each room, window and wall before any heat pump is sized.
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 Croydon 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.
Heat loss survey prices in Croydon
The ranges below are typical installed prices for homes in Greater London, including VAT. A survey sets the exact figure, because two similar-looking houses in Croydon 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 | £170–£450 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Croydon?
On the shortest day Croydon 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.

Heat loss surveys in Croydon: questions
Where would the outdoor unit go on a Croydon 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 Croydon home.
How soon can you survey a home in Croydon?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Croydon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Croydon home states the expected time.
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.
