What to know about heat loss surveys in Maldon
In Maldon, 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.
The survey in Maldon includes a check of where the outdoor unit could sit and how its sound would reach neighbours. For Maldon homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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
- Self-builders and architects who need emitter and system sizes early
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Recommended heat pump size and design flow temperature
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
Design outdoor temperatures for Maldon and the wider Essex come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in Maldon 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 Maldon: questions
How long does installation take in Maldon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Maldon home states the expected time.
How soon can you survey a home in Maldon?
Survey dates depend on how busy installers are in Essex. We offer the next available dates when you enquire and confirm them in writing.
How long does a heat pump survey take in Maldon?
A home survey in Maldon 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.
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.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
