Heat loss survey in Kingston upon Thames: what to expect
Most homes can run on a heat pump if the system is designed properly, and Kingston upon Thames is no different. The key is matching the heat pump and radiators to the home's heat loss.
For Kingston upon Thames homes with extensions or loft conversions, each part of the house is assessed on its own construction. Homeowners in Kingston upon Thames 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
- Homes with an existing heat pump that seems undersized or expensive to run
- Self-builders and architects who need emitter and system sizes early
What's included
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Kingston upon Thames home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
Homes in Kingston upon Thames 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.
What to budget for heat loss surveys in Kingston upon Thames
These are guide prices for Greater London, 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 | £170–£450 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Short winter days in Kingston upon Thames and what they mean
On the shortest day Kingston upon Thames gets about 7 hours 50 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 Kingston upon Thames: questions
How long does installation take in Kingston upon Thames?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Kingston upon Thames home states the expected time.
Do I need new radiators for a heat pump in Kingston upon Thames?
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 Kingston upon Thames home gives a room-by-room list.
Where would the outdoor unit go on a Kingston upon Thames 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 Kingston upon Thames home.
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.
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.
