About our air source heat pumps in Cadnam
A £2,500 grant is available for some air-to-air heat pumps, with conditions. 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. If you are dealing with comparing heat pump types and deciding on the outdoor unit position, we can help.
For a home around Cadnam that’s off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Whatever the visit, you get a written record: 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. File it with the manual, because it helps with any later warranty question.

What the work involves, system by system
Radiators and underfloor heating
Underfloor heating works well with heat pumps because it uses lower temperatures, and we can connect to it where it’s already in.
Air-to-air heat pumps
The £2,500 grant for air-to-air applies only when the system replaces the fossil-fuel heating and covers the whole home’s demand. It also has to be fitted by an MCS certified installer, in a home.

How it works
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Rural lanes and tight entrances are worth mentioning before a visit to Cadnam.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by 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
- Clear a path to the units and the space around them
- Let us know where the consumer unit is
- Plan for pets to be kept clear during the visit
Getting a price
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
Air source heat pumps around Cadnam
The 2021 Census found about 90% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder.
Landford Manor lies about 4.6 miles north-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. If your home is one of the older properties near Church of St Mary, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

What air conditioning will not do

- A grant for a home that does not meet the scheme rules
- Tax rulings, which only HMRC can give
- Any gas work on the existing boiler

FAQs for Cadnam
Is Cadnam 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 planning permission needed for a heat pump in Cadnam?
That depends on the building and where the outdoor unit goes. The Forest Central North Conservation Area is close to the centre of Cadnam. 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 the planning department at New Forest council, typically the authority for Cadnam.
Will I get records for the system?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Will skipping a service affect the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Cadnam and across Hampshire. Tell us who should receive the paperwork.
What does an air-to-water heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
