What you get

Heating that costs less to run, with £7,500 off the price

An air source heat pump takes warmth from the outside air, even on a frosty morning, and moves it into your radiators and hot water. For every unit of electricity it uses it delivers three to four units of heat, which is why a well-designed system costs less to run than a gas boiler and far less than electric heating. The south coast’s mild winters suit it better than almost anywhere in Britain.

Our team surveys every room and does the heat loss calculation properly, then MCS-certified partner engineers fit and commission the system. The £7,500 Boiler Upgrade Scheme voucher is applied for before any work starts and comes off your quote. If your home is not ready for a heat pump yet, we tell you what would make it ready rather than sell you one that struggles.

Included in every install

Free survey
Every room measured: insulation, windows, radiators and hot water. The heat loss calculation that sizes the system, done to MCS rules.
Air source heat pump
Sized to the heat loss, not to a package. Placed where it is quiet for you and for your neighbours.
Hot water cylinder
Most homes need one, in the airing cupboard or garage. Sized to the household.
Radiators checked
Each one assessed. The few that need to be larger are in the quote, not sprung on you later.
MCS-certified install
Fitted and commissioned by MCS-certified engineers, usually in two to five days. Certificate and handover included.

What we supply

Heat pumps we fit

Units chosen for the home, from manufacturers with a UK service network and a long warranty.

Is your home ready?

Who a heat pump suits, and who should wait

A heat pump works brilliantly in the right house and badly in the wrong one. The survey exists to tell them apart before you spend anything.

A good fit now
Most houses built since the 1990s, anything with cavity wall and loft insulation, homes on oil, LPG or electric heating, and anywhere with space outside for the unit and inside for a cylinder.
Worth a conversation
Older homes with some insulation done, homes with microbore pipework, and anyone whose boiler is on its last legs and wants a heat pump quote beside a boiler quote before deciding.
Not yet
Uninsulated solid-wall homes, flats with nowhere for the outdoor unit, and listed buildings where consent is unlikely. We say so at the survey, and tell you what would change it.

Straight answers

Heat pump questions from Dorset and Hampshire

Not here? The number at the top reaches a person who can answer it.

How much of the cost does the £7,500 grant cover?
A good share of it. The Boiler Upgrade Scheme pays £7,500 towards an air source heat pump, or £9,000 until March 2027 if your home runs on oil or LPG with no mains gas. The installer applies for the voucher before the work starts and the amount comes straight off your quote, so you never pay it and claim it back. The installation is also zero-rated for VAT until 31 March 2027. The rest depends on the size of the system, whether you need a hot water cylinder and how many radiators change, which is why we quote in writing after a survey rather than guess here.
Will a heat pump keep my house warm in winter?
Yes, if it is sized properly. Every system we fit starts with a room-by-room heat loss calculation, done to MCS rules, which works out what each room needs on the coldest day of a south coast winter (the design temperature here is around minus two degrees). The heat pump and radiators are chosen to meet that, and the unit keeps producing heat well below freezing. A heat pump runs at a lower temperature for longer than a boiler, so the house sits at a steady temperature instead of heating up and cooling down.
Is it cheaper to run than a gas boiler?
At today’s capped prices, slightly. A heat pump delivers three to four units of heat for each unit of electricity, so at 27p a unit the heat costs about 8p per kWh. A modern gas boiler turns 8p of gas into about 9p of heat once you allow for its efficiency, and you pay a separate gas standing charge on top. The gap widens on a heat pump tariff, which several suppliers now offer, and it is far bigger against electric radiators or storage heaters, which cost the full 27p for every unit of heat. Against oil it depends on the oil price that year; for off-gas homes the £9,000 grant does most of the work.
Do I need new radiators?
Sometimes a few. Because the water runs cooler than from a boiler, some radiators need to be a size larger to give off the same heat. The survey tells you which, and most homes change only a handful. Underfloor heating suits a heat pump perfectly. Microbore pipework or very small radiators throughout can make a home a poor fit, and we would say so at the survey.
Do I need planning permission for the outdoor unit?
In England, usually not. Since May 2025 an air source heat pump on a house is permitted development if the unit is under 1.5 cubic metres, it meets the MCS noise standard at your neighbours’ windows and the building is not listed. The old rule that it had to be a metre from the boundary has gone, and a detached house can have two units. Flats, listed buildings and conservation areas need a check, and Wales has its own rules. We confirm which applies to you at the survey.
How noisy is it?
The outdoor unit is about as loud as a fridge when you stand next to it. It is placed and sized so that what reaches your neighbours’ nearest window stays within the planning limit of 37 decibels. Indoors there is nothing to hear: no boiler, no fan, no flue.
Can I keep my gas boiler as a backup?
You can, but you lose the grant: the Boiler Upgrade Scheme does not fund hybrid systems. For most homes the heat pump is sized to do the whole job and the boiler goes, which also removes the gas standing charge. If you cook on gas, that connection can stay.
Does it work with solar panels and a battery?
Very well. In spring and autumn the panels cover a good part of the heating. In winter a battery charged on a cheap overnight rate runs the heat pump through the morning at a fraction of the daytime price. If you are thinking about solar too, one survey covers both.
