What to know about heat loss surveys in Peckham
In Peckham, 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.
A surveyor visits your Peckham home to measure each room, window and wall before any heat pump is sized. Houses in Peckham built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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
- Anyone getting a heat pump quote, as the first step
- Landlords comparing properties before deciding where to switch first
What's included
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
- Recommended heat pump size and design flow temperature
Homeowners in Peckham thinking about insulation work can use the survey to see how it would change their heat pump size.
Grants and rules for heat pumps in England
Homes in Peckham 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.
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 Peckham
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.

Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Short winter days in Peckham and what they mean
On the shortest day Peckham 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 Peckham: questions
Where would the outdoor unit go on a Peckham 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 Peckham home.
Can you service a heat pump in Peckham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Peckham, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Peckham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Peckham home states the expected time.
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.
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.
