What to know about heat loss surveys in Wood Green
A heat pump suits most Wood Green homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For Wood Green homes with extensions or loft conversions, each part of the house is assessed on its own construction. Homeowners in Wood Green 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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
Houses in Wood Green 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 Wood Green 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.

Short winter days in Wood Green and what they mean
On the shortest day Wood Green 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 Wood Green: questions
How long does installation take in Wood Green?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Wood Green home states the expected time.
How long does a heat pump survey take in Wood Green?
A home survey in Wood Green 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.
How soon can you survey a home in Wood Green?
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.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
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.
