What to know about heat loss surveys in Wanstead
Every property in Wanstead is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
For Wanstead homes with extensions or loft conversions, each part of the house is assessed on its own construction. The survey in Wanstead includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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.
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
What's included
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
A surveyor visits your Wanstead home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in England
Homes in Wanstead 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 costs around Wanstead
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 Wanstead 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.
Designing for Wanstead's winters
Wanstead sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat loss surveys in Wanstead: questions
How long does installation take in Wanstead?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Wanstead home states the expected time.
Can you service a heat pump in Wanstead that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wanstead, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Wanstead 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 Wanstead home.
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.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
