Heat loss survey in Hampstead: what to expect
The question for a Hampstead home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Homeowners in Hampstead thinking about insulation work can use the survey to see how it would change their heat pump size. For Hampstead 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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
What's included
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
Houses in Hampstead built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
Grants and rules for heat pumps in England
Homes in Hampstead 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 Hampstead
Guide prices for Hampstead and the rest of Greater London are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| 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 Hampstead and what they mean
On the shortest day Hampstead gets about 7 hours 49 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 Hampstead: questions
Do you cover West Hampstead as well as Hampstead?
Yes. We arrange surveys and installation in West Hampstead, which is about a mile south-west of Hampstead, and across Greater London.
How long does a heat pump survey take in Hampstead?
A home survey in Hampstead 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.
What size heat pump does a Hampstead 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 Hampstead home.
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.
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.
