What to know about heat loss surveys in Stockton-on-Tees
A heat pump suits most Stockton-on-Tees homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For Stockton-on-Tees homes with extensions or loft conversions, each part of the house is assessed on its own construction. A surveyor visits your Stockton-on-Tees 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.
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
The survey in Stockton-on-Tees 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
Homes in Stockton-on-Tees can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.
What to budget for heat loss surveys in Stockton-on-Tees
The ranges below are typical installed prices for homes in County Durham, including VAT. A survey sets the exact figure, because two similar-looking houses in Stockton-on-Tees 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–£390 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Stockton-on-Tees's winters
On the shortest day Stockton-on-Tees gets only about 7 hours 15 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 Stockton-on-Tees: questions
Can you service a heat pump in Stockton-on-Tees that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Stockton-on-Tees, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Stockton-on-Tees?
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.
What size heat pump does a Stockton-on-Tees 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 Stockton-on-Tees home.
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.
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.
