Heat pumps in Longfield Hill: local notes
About 48% of homes in and around Longfield Hill date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 86% of households live in detached or semi-detached houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder. Listed buildings are part of the picture here: about 3 within half a mile of the centre, such as Ivydew Cottage (grade II). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the local planning authority (normally Dartford council).
Live in one of the older houses around Church of St Mildred? Expect the survey to look closely at heat loss and at the building’s planning status.

Air source heat pumps in Longfield Hill, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. If you are dealing with checking eligibility for a heat pump grant and no space for a hot water cylinder, we can sort it out.
Space for an outdoor unit is rarely an issue near Longfield Hill, so the design focuses on heat loss and radiators.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Longfield Hill questions
Is Longfield Hill within the area you cover?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is the heat pump grant available in Longfield Hill?
Longfield Hill is covered, as the scheme runs across England and Wales. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How much time does a heat pump install need?
It takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
How much does an air source heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
How it works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes from a couple of days to around a week, depending on the system and how much of the heating changes. Seeing the property in photos first means the trip to Longfield Hill can be planned properly.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Arrange for someone to be there to let us in
- Dig out any previous service or F-Gas records
- Let us know where the consumer unit is

Looking after it afterwards
After the visit, a few habits help:
- Keep the MCS certificate with the manufacturer’s paperwork
- Read the manufacturer’s warranty terms for your brand
- Check eligibility for the Boiler Upgrade Scheme early
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside, so keep it clear all year.
What the work involves, system by system
The Boiler Upgrade Scheme
Eligibility depends on the property and the scheme rules, so we check before you commit.
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed building consent is a separate matter, and we check the position for your property.
Common problems we fix in Longfield Hill
Extensions, renovations and loft conversions are a natural time to rethink the heating. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
Keep an eye out for these signs:
- Planning and permitted development questions
- Deciding which kind of heat pump suits the home
- Working out where a cylinder could go
With Cobham College about 2.8 miles east, it’s worth asking whether your own home is listed before planning a heat pump.
