Heat loss survey in Yarm: what to expect
The question for a Yarm 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.
A surveyor visits your Yarm home to measure each room, window and wall before any heat pump is sized. For Yarm 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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
What's included
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- 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
Homeowners in Yarm 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 Yarm quote.
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.
What to budget for heat loss surveys in Yarm
The ranges below are typical installed prices for homes in North Yorkshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Yarm 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 | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Yarm?
On the shortest day Yarm gets only about 7 hours 16 minutes of daylight and the noon sun sits around 12° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.

Heat loss surveys in Yarm: questions
What size heat pump does a Yarm 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 Yarm home.
Do you cover Thornaby-on-Tees as well as Yarm?
Yes. We arrange surveys and installation in Thornaby-on-Tees, which is about 3 miles north-east of Yarm, and across North Yorkshire.
Can you service a heat pump in Yarm that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Yarm, whoever fitted them. Tell us the make and model when you book.
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.
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.
