About our air source heat pumps in Kevington
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler does not qualify. Common call-outs are for planning and permitted development questions and finding a place for the outdoor unit, on underfloor heating, homes heated by oil, LPG or gas and radiator systems.
In a flat in Kevington, the lease and the freeholder usually decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

What affects the cost of air source heat pumps
Jobs vary more than people expect. The main factors:
- The pipe route between the units
- Whether it’s a simple split or a larger system
- The brand, model and parts involved
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll explain what it covers.
What we need to know
Simple jobs can often be priced from pictures and some basics. Useful things to send:
- Any error code or flashing light on the display
- Where the outdoor unit is, or where you’d like it
- The postcode and whether it’s a home, flat or business
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.
How the visit works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, 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. Some blocks in Kevington need contractor details in advance, so tell us what your building needs.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Let us know where the consumer unit is
- Mention any roof access, ladders or high-level work
- Keep pets and children away from the work area
Getting a price
Photos are enough for some jobs; others need a visit first. 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.
Advice
Kevington questions
Can you fit air conditioning in a London flat in Kevington?
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.
Can I get the Boiler Upgrade Scheme grant in Kevington?
Yes, if the home and the heat pump meet the scheme’s rules: Kevington is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Do I need new radiators for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Kevington and across Greater London. Tell us who should receive the paperwork.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Does servicing affect my warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.

Signs you need air source heat pumps in Kevington
An ageing boiler is often the moment people start thinking about a heat pump. Starting early leaves time for the survey, the design and any grant application, rather than rushing a replacement in winter.
If any of these sounds familiar, it’s worth a diagnosis:
- Questions about where the outdoor unit can go
- Choosing between air-to-water and air-to-air
- Checking whether planning permission is needed
Live in one of the older houses around Unity Church? Expect the survey to look closely at heat loss and at the building’s planning status.
Questions to ask before booking
- Whether the quote is a fixed price
- Exactly what the price includes, from supply and fitting to commissioning
- Whether a new circuit is included and who certifies it
Heat pumps in Kevington: local notes
About 43% of homes in the Kevington area date from 1945 to 1972, according to Valuation Office Agency council tax records. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Lullingstone Castle lies about 3.2 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
