What to know about heat loss surveys in Shoreham-by-Sea
Every property in Shoreham-by-Sea 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.
Design outdoor temperatures for Shoreham-by-Sea and the wider West Sussex come from local cold-weather data, not a national average. Houses in Shoreham-by-Sea built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Radiator schedule with any upgrades needed for each room
The survey in Shoreham-by-Sea 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
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Shoreham-by-Sea quote.
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 costs around Shoreham-by-Sea
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 Shoreham-by-Sea 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.
Designing for Shoreham-by-Sea's winters
On the shortest day Shoreham-by-Sea gets about 7 hours 56 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.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Shoreham-by-Sea: questions
Can you service a heat pump in Shoreham-by-Sea that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Shoreham-by-Sea, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Shoreham-by-Sea 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 Shoreham-by-Sea home.
How soon can you survey a home in Shoreham-by-Sea?
Survey dates depend on how busy installers are in West Sussex. We offer the next available dates when you enquire and confirm them in writing.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
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.
