What to know about heat loss surveys in Berwick-upon-Tweed
The question for a Berwick-upon-Tweed 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.
For Berwick-upon-Tweed homes with extensions or loft conversions, each part of the house is assessed on its own construction. Houses in Berwick-upon-Tweed built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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
- Self-builders and architects who need emitter and system sizes early
- Anyone getting a heat pump quote, as the first step
What's included
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
Design outdoor temperatures for Berwick-upon-Tweed and the wider Northumberland come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in Berwick-upon-Tweed 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.

Short winter days in Berwick-upon-Tweed and what they mean
On the shortest day Berwick-upon-Tweed gets only about 7 hours 00 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Heat loss surveys in Berwick-upon-Tweed: questions
How soon can you survey a home in Berwick-upon-Tweed?
Survey dates depend on how busy installers are in Northumberland. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Berwick-upon-Tweed that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Berwick-upon-Tweed, whoever fitted them. Tell us the make and model when you book.
Do you cover Alnwick as well as Berwick-upon-Tweed?
Yes. We arrange surveys and installation in Alnwick, which is about 28 miles south-east of Berwick-upon-Tweed, and across Northumberland.
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.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
