Safe owner checks
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Air source heat pumps in Sway
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 doesn’t qualify. Typical jobs include working out whether radiators need upsizing and checking whether planning permission is needed, on underfloor heating, air-to-water heat pumps and homes heated by oil, LPG or gas.
For a house near Sway, space outside is rarely the problem, so the main questions are heat loss, radiators and the electrics.
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, because it helps with any later warranty question.

Different systems, different jobs
Outdoor unit position and planning
Under permitted development, the outdoor unit must be 1.5 m³ or less and must meet MCS 020(a) and not be used solely for cooling. Listed building curtilages are excluded.
The Boiler Upgrade Scheme
The Boiler Upgrade Scheme covers England and Wales: £7,500 for air-to-water and ground source, and £2,500 for air-to-air in limited cases. The application goes through the installer.
Why act early in Sway
The two types suit different homes and needs. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions. We explain which makes sense for you. An early booking makes the visit to Sway easier to arrange.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will explain each part.

What happens on the day
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. The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. A few pictures let us plan a visit to a place like Sway.
- First we find out about the property, the heating you have now and what you are hoping for.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Let us know if the building has a permit or sign-in process
- Mention any roof access, ladders or high-level work
Ask for a quote
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. Tell us the address and what you need, and many jobs can be priced from that.

What else we do in Sway
Air source heat pumps around Sway
On the National Heritage List, around 3 entries fall within 0.5 miles of the middle of Sway; Forest Heath Hotel (grade II) is one. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at New Forest council, which normally handles Sway. About 84% of households live in detached or semi-detached houses, according to the last census (2021). Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Live in one of the older houses around St Luke's Church? Expect the survey to look closely at heat loss and at the building’s planning status. If your home is near Sway station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

Common questions in Sway
Will you come out to Sway?
Yes. Sway is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Sway?
Sway is covered, as the scheme runs across England and Wales. 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’re MCS certified.
When will I hear back?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source, and we explain which suits your home.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Which accreditations do you hold?

How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
