Air source heat pumps in Crayford
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. The work covers hot water cylinders, homes heated by oil, LPG or gas and underfloor heating, and people most often call us about an oil, LPG or gas boiler near the end of its life and questions about where the outdoor unit can go.
Homes around Crayford normally have space for an outdoor unit and a hot water cylinder, so the main questions are heat loss, radiators and the electrics.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Heat pumps in Crayford: local notes
About 42% of homes across Crayford and its surrounding area were built between the wars, according to VOA council tax data. For homes of that age, the survey checks the insulation, the radiators and the hot water setup.
If your home is near Crayford station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Live in one of the older houses around Church of St Paulinus? Expect the survey to look closely at heat loss and at the building’s planning status.

Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. A unit used solely for cooling is not covered, so check with the council.
Hot water cylinders
Cylinder size is based on your household’s needs.
How it works
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. On site, the work 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. Visits to a place like Crayford are planned ahead, so we arrive with what the job needs.
- First we find out about the property, the heating you have now and what you are hoping for.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Getting ready for the visit
- Plan for pets to be kept clear during the visit
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the consumer unit or fuse board

Crayford questions
Will a heat pump in Crayford need planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Crayford holds about 15 listed buildings and structures. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Crayford, typically Bexley council).
Can I get the Boiler Upgrade Scheme grant in Crayford?
Crayford is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You do not apply yourself: the MCS certified installer does, which is us.
Do you work in Crayford?
Yes. Our engineers work in Crayford, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Are my radiators big enough for a heat pump?
It varies from room to room. We check them all during the survey, so the quote covers any changes.

Before you call an engineer
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
