Air source heat pumps in Keyhaven, done properly
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. Eligibility depends on the property, so we confirm it before anything is agreed. The work covers hot water cylinders, radiator systems and homes heated by oil, LPG or gas, and people most often call us about an oil, LPG or gas boiler near the end of its life and checking emitters for a heat pump.
Homes around Keyhaven typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Signs you need air source heat pumps in Keyhaven
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
Look out for these signs:
- A boiler that’s getting old
- Comparing heat pump types
- Replacing a combi boiler with a heat pump
Every heat pump design starts with a room-by-room heat loss calculation.
What to look for in a quote
- Whether the company is F-Gas certified, and whether you can check it
- Whether you get F-Gas records where refrigerant is involved
- Whether they looked at the job before pricing it
Keyhaven: your questions answered
Does sea air affect air conditioning in Keyhaven?
It can, as Keyhaven is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Is Keyhaven within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Will my radiators work with a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Only in limited cases, with a grant of £2,500. The system must replace the existing fossil-fuel heating, meet the home’s full heating demand, be installed by an MCS certified installer and be in a home.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book, and we are happy to show ours.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.

How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit 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. Seeing the property in pictures first means the trip to Keyhaven can be planned properly.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Clear the space around the indoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area

Advice
Before you call an engineer
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone 07833 053749 or email us.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Homes in Keyhaven and heat pumps
The coast is only about 1 mile from Keyhaven. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. The last census (2021) found about 71% 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. Keyhaven’s centre falls inside the Keyhaven Conservation Area. There are 2 conservation areas within a mile of the centre of Keyhaven. Listed buildings are part of the picture here: about 8 within half a mile of the centre, such as Aubrey House (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Live in one of the older houses around Church of All Saints? Expect the survey to look closely at heat loss and at the building’s planning status.

Hot water cylinders
An older cylinder may not suit a heat pump, and we explain whether yours can stay.
Heat loss surveys
Getting the survey right avoids undersized or oversized systems, and both cause problems.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
