Heat loss survey in Wymondham: what to expect
A heat pump suits most Wymondham homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Houses in Wymondham built in different eras can need very different heat pump sizes, which is why each is calculated room by room. For Wymondham 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.
- Landlords comparing properties before deciding where to switch first
- 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
- Radiator schedule with any upgrades needed for each room
- Written results in your quote, or a stand-alone report if you order one
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
Homeowners in Wymondham 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
Homes in Wymondham 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 Wymondham and what they mean
On the shortest day Wymondham gets about 7 hours 38 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat loss surveys in Wymondham: questions
Do I need new radiators for a heat pump in Wymondham?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Wymondham home gives a room-by-room list.
Do you cover Norwich as well as Wymondham?
Yes. We arrange surveys and installation in Norwich, which is about 9 miles north-east of Wymondham, and across Norfolk.
Can you service a heat pump in Wymondham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wymondham, whoever fitted them. Tell us the make and model when you book.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies 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.
