Most heat pumps that disappoint were sized wrong.

We do the room-by-room heat loss calculation before we quote, not after you have signed. It takes a morning, it decides everything, and roughly a third of the time it tells us to walk away.

45°

A heat pump runs cooler than a boiler

Around 45 degrees rather than 70. Everything that follows is a consequence of that one number.

So a radiator does about half the work

The same radiator that was adequate at 70 degrees is not adequate at 45. Some of yours will need to change. Not all of them.

Which is why there is one calculation

Room by room, measured in your house. It names the unit size and the exact radiators. Skip it and you get a system that is loud, expensive and cold.

Before you talk to anyone

Does it pay back, for your house?

Drag your current heating bill. The chart is ten years of it, against the same ten years with a heat pump, with the Boiler Upgrade Scheme already taken off the install. We have set the assumptions to the cautious end on purpose.

Staying as you are Heat pump, install included

The assumptions, so you can argue with them
  • Gas at 6.4p and electricity at 25.8p per kWh, a boiler running at 86% in the real world rather than on the badge.
  • Install between £9,000 and £16,000 depending on the house, with the £7,500 Boiler Upgrade Scheme grant deducted. Larger bill, larger house, larger install: the slider moves both.
  • £105 a year from dropping the gas standing charge once the gas is disconnected.
  • No price inflation on either fuel, which flatters your current boiler rather than the heat pump.
  • No maintenance difference, no resale value, no export income from solar.

This is a model, not a quote. The number that matters comes from the heat loss calculation we do at the survey, and that one is specific to your house.

What we do

Four things, done properly,
rather than everything.

01

Air source heat pumps

The main job. Survey, heat loss calculation, radiator sizing, install, commissioning.

 02

Solar and battery

Panels sized around the heat pump rather than sold separately from it, because a heat pump turns your heating bill into the bill solar reduces.

 03

Radiators and pipework

The part that decides whether the finished system is quiet, cheap to run and actually warm, and the part most quotes leave vague until it is too late.

 04

Servicing and aftercare

Annual service, remote monitoring, and a number that a person answers.

How it goes

Five steps, and you can
stop after any of them.

01

A call, not a visit

Fifteen minutes on the phone tells us whether this is worth either of our time. Roughly a third of these calls end with us saying not yet, and that is a fine outcome.

02

The survey

Two to three hours in the house. Every room measured, every radiator recorded, the fabric assessed. You get the heat loss calculation itself, not a summary of it.

03

The quote

One price, itemised, with the grant already deducted. If radiators need changing they are on the quote as a line, never a surprise after the units arrive.

04

The install

Three to five days for a typical house. The old system stays live until the new one is commissioned, so you are never without heating overnight.

05

Commissioning and handover

Flow temperature set against the actual calculation, controls explained once properly, and the paperwork for the grant filed by us.

What people say

They turned down the first job we asked them for, told us the loft insulation was the better spend, and came back a year later to do the heat pump. That is the reason we recommend them.

Marianne T. · Knaresborough

Came off oil. The survey took most of a morning and the quote matched it to the pound. Two radiators changed, not the eight another firm insisted on.

David and Ruth P. · Thirsk

The flow temperature was set to the calculation rather than to a default, which apparently is unusual. House is warm, running cost is what they said it would be.

Simon A. · Harrogate

Where we work

Within about an hour
of Harrogate.

We keep the radius tight on purpose. A system we can be at in an hour is a system we actually monitor and service, rather than one we commission and forget.

Start with the calculation,
not with the quote.

Fifteen minutes on the phone tells us both whether this is worth a survey. If it is not, we will say so and tell you what to spend the money on instead.
