Heat loss survey for Romsey homes
Every property in Romsey 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 Romsey built in different eras can need very different heat pump sizes, which is why each is calculated room by room. A surveyor visits your Romsey 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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
What's included
- Room-by-room heat loss calculation using the MCS method
- Radiator schedule with any upgrades needed for each room
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
The survey in Romsey 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 Romsey 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Winter daylight and heating in Romsey
On the shortest day Romsey gets about 7 hours 55 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat loss surveys in Romsey: questions
How long does installation take in Romsey?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Romsey home states the expected time.
Do I need new radiators for a heat pump in Romsey?
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 Romsey home gives a room-by-room list.
Do you cover Totton as well as Romsey?
Yes. We arrange surveys and installation in Totton, which is about 5 miles south of Romsey, and across Hampshire.
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.
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.
