Before you book: heat loss surveys in Folkestone
The question for a Folkestone home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
A surveyor visits your Folkestone home to measure each room, window and wall before any heat pump is sized. Houses in Folkestone 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.
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
What's included
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
- Recommended heat pump size and design flow temperature
- Outdoor unit siting options and noise check
For Folkestone homes with extensions or loft conversions, each part of the house is assessed on its own construction.
Grants and rules for heat pumps in England
Homes in Folkestone 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 Folkestone
The ranges below are typical installed prices for homes in Kent, including VAT. A survey sets the exact figure, because two similar-looking houses in Folkestone 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.
Short winter days in Folkestone and what they mean
Folkestone sees roughly 7 hours 54 minutes of daylight in late December against 16 hours 34 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.

- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Folkestone: questions
Do I need new radiators for a heat pump in Folkestone?
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 Folkestone home gives a room-by-room list.
How long does installation take in Folkestone?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Folkestone home states the expected time.
What size heat pump does a Folkestone 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 Folkestone home.
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.
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.
