Heat loss survey for Eastleigh homes
Most homes can run on a heat pump if the system is designed properly, and Eastleigh is no different. The key is matching the heat pump and radiators to the home's heat loss.
Houses in Eastleigh built in different eras can need very different heat pump sizes, which is why each is calculated room by room. A surveyor visits your Eastleigh 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.
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- 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
The survey in Eastleigh 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 Eastleigh 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.
Guide prices for heat loss surveys in Eastleigh
The ranges below are typical installed prices for homes in Hampshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Eastleigh can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£410 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Eastleigh?
On the shortest day Eastleigh 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 Eastleigh: questions
Do you cover Southampton as well as Eastleigh?
Yes. We arrange surveys and installation in Southampton, which is about 5 miles south-west of Eastleigh, and across Hampshire.
Do I need new radiators for a heat pump in Eastleigh?
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 Eastleigh home gives a room-by-room list.
How long does a heat pump survey take in Eastleigh?
A home survey in Eastleigh usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
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.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
