Heat loss survey in St Neots: what to expect
A heat pump suits most St Neots homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Design outdoor temperatures for St Neots and the wider Cambridgeshire come from local cold-weather data, not a national average. For St Neots 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
- Anyone getting a heat pump quote, as the first step
What's included
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
Houses in St Neots built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
Grants and rules for heat pumps in England
Homes in St Neots 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.

Designing for St Neots's winters
St Neots has about 7 hours 42 minutes of daylight at midwinter and 16 hours 47 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat loss surveys in St Neots: questions
How long does installation take in St Neots?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a St Neots home states the expected time.
What size heat pump does a St Neots 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 St Neots home.
Can you service a heat pump in St Neots that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in St Neots, whoever fitted them. Tell us the make and model when you book.
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.
