Air source heat pumps for homes and businesses in South Down
An air-to-water heat pump costs £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. We are often asked to deal with checking eligibility for a heat pump grant and checking emitters for a heat pump, on underfloor heating, radiator systems and air-to-water heat pumps.
In a place like South Down, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
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 and it’s worth keeping safe.

For landlords and property managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side and send the records to whoever needs them.
Common questions in South Down
Will you come out to South Down?
Yes. South Down is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I get the Boiler Upgrade Scheme grant in South Down?
South Down is in England, where the Boiler Upgrade Scheme runs. 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. The installer applies, and we are MCS certified.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Homes in South Down and heat pumps
The 2021 Census found about 72% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. 2 conservation areas lie within a mile of central South Down. On the National Heritage List, around 3 entries fall within 0.5 miles of the middle of South Down; Bourne House (grade II) is one. Where a home is affected, the outdoor unit position is settled with the local planning authority (usually Winchester City council) before the heat pump design is finished.
If you live near Shawford station, the survey compares air-to-water and air-to-air for your home before anything is quoted.

The process
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. Pictures of the space and where the outdoor unit could go let us plan the work in South Down.
- We start with your plans and the property.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Name a contact who can meet us at the agreed time
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets and children away from the work area

How we price air source heat pumps
We quote each job individually. These are the things that affect it:
- Access, including height, roofs and ladders
- The type of system, from a single split to a larger system
- What electrical work the job needs
What you pay reflects the actual work. That’s why we look at the job first, from pictures or on a survey, and why the quote is fixed before any work starts.
What to send for a quote
When you call or email, it’s useful to have:
- The remote or wall controller showing any error
- Your consumer unit or fuse board
- The rating plate or label on any existing unit

What we’re called out for in South Down
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.
Look out for these signs:
- Questions about where the outdoor unit can go
- No space for a hot water cylinder
- Planning and permitted development questions
Period properties close to Church of All Saints can suit a heat pump, though insulation and any heritage protection are checked first.
