Before you book: heat loss surveys in Tottenham
In Tottenham, 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.
Homeowners in Tottenham thinking about insulation work can use the survey to see how it would change their heat pump size. A surveyor visits your Tottenham home to measure each room, window and wall before any heat pump is sized.
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.
- Homes with an existing heat pump that seems undersized or expensive to run
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
What's included
- 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
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
Design outdoor temperatures for Tottenham and the wider Greater London come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Tottenham quote.
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 Tottenham
Guide prices for Tottenham 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 Tottenham and what they mean
Tottenham 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.
From survey to switch-on in Tottenham

- A surveyor visits your Tottenham home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Tottenham: questions
Can you service a heat pump in Tottenham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tottenham, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Tottenham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Tottenham home states the expected time.
Do you cover Wood Green as well as Tottenham?
Yes. We arrange surveys and installation in Wood Green, which is about 2 miles west of Tottenham, and across Greater London.
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.
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.
