What to know about heat loss surveys in Chester-le-Street
In Chester-le-Street, 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.
Homeowners in Chester-le-Street thinking about insulation work can use the survey to see how it would change their heat pump size. A surveyor visits your Chester-le-Street 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
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
What's included
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
The survey in Chester-le-Street 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 Chester-le-Street 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 Chester-le-Street: questions
Can you service a heat pump in Chester-le-Street that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Chester-le-Street, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Chester-le-Street?
Survey dates depend on how busy installers are in County Durham. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Chester-le-Street?
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 Chester-le-Street home gives a room-by-room list.
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.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
