How we handle air source heat pumps in Milton
For an air-to-water heat pump, the price is £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 air-to-water heat pumps, homes heated by oil, LPG or gas and underfloor heating, and people most often call us about questions about listed buildings or conservation areas and a boiler that’s getting old.
If your home near Milton has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Homes in Milton and heat pumps
At about 1 mile from the coast, Milton is close enough for sea air to matter. Near the coast, we choose the outdoor unit position with salt-laden wind in mind. The Valuation Office Agency’s council tax figures put about 52% of homes across Milton and its surrounding area before 1919, and the last census (2021) found about 62% of households in terraced houses. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. In a terrace, the outdoor unit position and the MCS noise check need particular care.
Period properties close to Church of St James can suit a heat pump, though insulation and any heritage protection are checked first.

Other services in Milton
After we’ve gone
Think of this as the after-treatment advice, short and simple:
- Seal draughts where you can
- Do not block radiators or indoor units with furniture
- Avoid switching the heat pump on and off often
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
Keep radiators and indoor units unobstructed so the heat can get into the room.
For landlords and property managers
We regularly work with managing agents. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Questions from Milton
Can I fit a heat pump in Milton without planning permission?
That depends on the building and where the outdoor unit goes. There’s a conservation area, the Essex Road Conservation Area, close to central Milton. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Portsmouth council, usually the authority for Milton.
Will you come out to Milton?
Yes. Milton is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Do I get paperwork after the visit?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
How long will it take to install a heat pump?
An installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The survey lets us set a firm programme, and you can call 07833 053749, or email if that’s easier to book it.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: a look first, a fixed-price quote and written records.
Signs you need air source heat pumps in Milton
A common reason is wanting to stop burning gas, oil or LPG. A heat pump runs on electricity and takes heat from the outside air, which is why it fits that aim.
Customers normally contact us when they notice something like this:
- Deciding which kind of heat pump suits the home
- Checking whether planning permission is needed
- Deciding on the outdoor unit position
For a home near Fratton station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.
What your quote should include
- Whether a new circuit is included and who certifies it
- What’s in the price and what is not
- What happens if the job turns out to be different on the day
How it works
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we clear up before we go. Send pictures of the space and the outside wall, and we can plan the work near Milton.
- 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.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- After commissioning, you get the MCS certificate and a handover.
How to prepare
- Make sure we can reach the outdoor unit, or where it will go
- Keep pets out of the rooms we’re working in
- Mention any managing agent or landlord rules we need to follow
Getting a price
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 before any work starts.
