Heat loss survey in Hornchurch: what to expect
Most homes can run on a heat pump if the system is designed properly, and Hornchurch is no different. The key is matching the heat pump and radiators to the home's heat loss.
Houses in Hornchurch built in different eras can need very different heat pump sizes, which is why each is calculated room by room. A surveyor visits your Hornchurch 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.
- Landlords comparing properties before deciding where to switch first
- 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
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
The survey in Hornchurch includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Hornchurch 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 surveys in Hornchurch: questions
How soon can you survey a home in Hornchurch?
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.
Do I need new radiators for a heat pump in Hornchurch?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Hornchurch home gives a room-by-room list.
Do you cover Upminster as well as Hornchurch?
Yes. We arrange surveys and installation in Upminster, which is about 2 miles east of Hornchurch, and across Greater London.
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.
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.
