Air source heat pumps in Biggin Hill
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. Typical jobs include not knowing whether a grant applies and a boiler that’s getting old, on air-to-air heat pumps, radiator systems and underfloor heating.
For flats in Biggin Hill, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, and we check before designing.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Air source heat pumps in Biggin Hill: the local picture
The Valuation Office Agency’s council tax figures date about 42% of homes in the Biggin Hill area to the post-war years, 1945 to 1972, and about 67% of households live in detached or semi-detached houses, according to Census 2021 figures. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
With Down House about 1.7 miles north-east, it’s worth asking whether your own home is listed before planning a heat pump.

VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that, under HMRC Notice 708/6. It doesn’t apply to businesses.
The Boiler Upgrade Scheme
In England and Wales, the Boiler Upgrade Scheme offers grants towards heat pumps: £7,500 for air-to-water (and ground source), and £2,500 for air-to-air with strict conditions. The application goes through the installer.
When to call us in Biggin Hill
Homes with electric heating sometimes look at heat pumps as an alternative. The survey tells you whether it’s practical and what’s involved along with whether any grant could apply.
The things we are asked about most include:
- An oil, LPG or gas boiler near the end of its life
- Choosing between air-to-water and air-to-air
- Checking eligibility for a heat pump grant
Period properties close to St Mark's Church can suit a heat pump, though insulation and any heritage protection are checked first.
Questions to ask before booking
- Proof of F-Gas company certification
- Whether testing, commissioning and paperwork are included
- Whether the quote is a fixed price
Landlords, agents and facilities managers
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Facilities teams in offices, schools and public buildings book us too across Greater London. Larger buildings can be done in stages to keep disruption down.
Biggin Hill: your questions answered
Can I get the Boiler Upgrade Scheme grant in Biggin Hill?
Yes, if the home and the heat pump meet the scheme’s rules: Biggin Hill is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
Can I have air conditioning in a flat in Biggin Hill?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.
Do you survey before quoting?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
How quickly will you reply?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Do you work in Biggin Hill?
Yes. Our engineers work in Biggin Hill, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
The process
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 we test, record and explain. The middle part takes longest, and that takes a few days on site, depending on the cylinder, the radiators and the pipework involved. In a London area like Biggin Hill, parking and access are worth sorting out before the day.
- We talk through your home, your current heating and what you want from a heat pump.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- 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.
- The system is commissioned and registered under MCS, and we show you how to use it.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Dig out any previous service or F-Gas records
- Move furniture away from the wall where we will be working
Get a fixed-price quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
