Before you book: heat loss surveys in Hertford
Homes around Hertford range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For Hertford homes with extensions or loft conversions, each part of the house is assessed on its own construction. A surveyor visits your Hertford 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
- Landlords comparing properties before deciding where to switch first
What's included
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
The survey in Hertford 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
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 Hertford 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 costs around Hertford
These are guide prices for Hertfordshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

| 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.
Short winter days in Hertford and what they mean
On the shortest day Hertford gets about 7 hours 47 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat loss surveys in Hertford: questions
Where would the outdoor unit go on a Hertford house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Hertford home.
Can you service a heat pump in Hertford that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hertford, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Hertford?
Survey dates depend on how busy installers are in Hertfordshire. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
