Heat loss survey in Alnwick: what to expect
Every property in Alnwick is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Houses in Alnwick built in different eras can need very different heat pump sizes, which is why each is calculated room by room. For Alnwick 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.
- Homes with an existing heat pump that seems undersized or expensive to run
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
A surveyor visits your Alnwick home to measure each room, window and wall before any heat pump is sized.
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 Alnwick 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 Alnwick: questions
Do you cover Morpeth as well as Alnwick?
Yes. We arrange surveys and installation in Morpeth, which is about 17 miles south of Alnwick, and across Northumberland.
How soon can you survey a home in Alnwick?
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 Alnwick that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Alnwick, whoever fitted them. Tell us the make and model when you book.
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.
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.
