What to know about heat loss surveys in Littlehampton
Every property in Littlehampton 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.
A surveyor visits your Littlehampton home to measure each room, window and wall before any heat pump is sized. Homeowners in Littlehampton thinking about insulation work can use the survey to see how it would change their heat pump size.
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.
- Self-builders and architects who need emitter and system sizes early
- 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
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Room-by-room heat loss calculation using the MCS method
Design outdoor temperatures for Littlehampton and the wider West Sussex come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in Littlehampton 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.
Heat loss survey prices in Littlehampton
The ranges below are typical installed prices for homes in West Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Littlehampton 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 | £160–£420 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Littlehampton?
Littlehampton sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat loss surveys in Littlehampton: questions
What size heat pump does a Littlehampton 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 Littlehampton home.
How long does installation take in Littlehampton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Littlehampton home states the expected time.
Can you service a heat pump in Littlehampton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Littlehampton, 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.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
