Before you book: heat loss surveys in Bishop's Stortford
The question for a Bishop's Stortford home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
The survey in Bishop's Stortford includes a check of where the outdoor unit could sit and how its sound would reach neighbours. A surveyor visits your Bishop's Stortford 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
- Homes with an existing heat pump that seems undersized or expensive to run
- Anyone getting a heat pump quote, as the first step
What's included
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
Homeowners in Bishop's Stortford thinking about insulation work can use the survey to see how it would change their heat pump size.
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 Bishop's Stortford 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 surveys in Bishop's Stortford: questions
What size heat pump does a Bishop's Stortford home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Bishop's Stortford home.
Can you service a heat pump in Bishop's Stortford that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bishop's Stortford, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Bishop's Stortford?
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 Bishop's Stortford home gives a room-by-room list.
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.
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.
