Before you book: heat loss surveys in Hemel Hempstead
A heat pump suits most Hemel Hempstead homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Houses in Hemel Hempstead built in different eras can need very different heat pump sizes, which is why each is calculated room by room. A surveyor visits your Hemel Hempstead 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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Self-builders and architects who need emitter and system sizes early
What's included
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
Design outdoor temperatures for Hemel Hempstead and the wider Hertfordshire 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 Hemel Hempstead quote.
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.
Heat loss survey prices in Hemel Hempstead
The ranges below are typical installed prices for homes in Hertfordshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Hemel Hempstead can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £160–£420 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Hemel Hempstead?
Hemel Hempstead has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat loss surveys in Hemel Hempstead: questions
How soon can you survey a home in Hemel Hempstead?
Survey dates depend on how busy installers are in Hertfordshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Berkhamsted as well as Hemel Hempstead?
Yes. We arrange surveys and installation in Berkhamsted, which is about 5 miles west of Hemel Hempstead, and across Hertfordshire.
Do I need new radiators for a heat pump in Hemel Hempstead?
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 Hemel Hempstead home gives a room-by-room list.
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.
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.
