- Finding a place for the outdoor unit
- Checking whether planning permission is needed
- Checking eligibility for a heat pump grant
The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. 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. If a lane or gateway near Leigh is tight for a van, let us know and we will plan for it.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Mention any roof access, ladders or high-level work
- Keep pets out of the rooms we’re working in
- Tell us about parking and loading

Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
Air source heat pumps in Leigh, done properly
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. Common call-outs are for a boiler that’s getting old and finding a place for the outdoor unit, across radiator systems, underfloor heating and homes heated by oil, LPG or gas.
Homes around Leigh usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Homes in Leigh and heat pumps
About 43% of homes in Leigh and the neighbourhoods around it date from 1945 to 1972, according to VOA council tax data, and about 82% 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. Houses typically have space for an outdoor unit and a hot water cylinder.
For a home near Leigh (Kent) station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

FAQs for Leigh
Can I fit a heat pump in Leigh without planning permission?
It depends on the property. The centre of Leigh is in a conservation area. 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 don’t 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 Sevenoaks council, which is usually the planning authority for Leigh.
Is Leigh within the area you cover?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
What does an air-to-water 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.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.

Rented and managed buildings
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Do you need air source heat pumps in Leigh?
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Starting early leaves time for the survey, the design and any grant application, rather than rushing a replacement in winter.
The things we are asked about most are:
- Questions about the Boiler Upgrade Scheme
- Comparing heat pump types
- Working out whether radiators need upsizing
Historic houses such as Penshurst Place, about 2 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.
Questions to ask before you book
- Which VAT rate the quote uses, and why
- Whether the quote is a fixed price
- Who does the electrical work, and whether they can certify it
Different systems, different jobs
Outdoor unit position and planning
The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
Heat loss surveys
Getting the survey right avoids undersized or oversized systems and that matters for comfort and running.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
