Heat loss survey for Worthing homes
Every property in Worthing 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.
The survey in Worthing includes a check of where the outdoor unit could sit and how its sound would reach neighbours. Houses in Worthing 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.
- 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
- Radiator schedule with any upgrades needed for each room
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
Homeowners in Worthing 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 Worthing 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 Worthing
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 Worthing 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.
Short winter days in Worthing and what they mean
Worthing 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 Worthing: questions
Do I need new radiators for a heat pump in Worthing?
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 Worthing home gives a room-by-room list.
Can you service a heat pump in Worthing that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Worthing, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Worthing?
A home survey in Worthing 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.
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.
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.
