Heard heat pumps don't work in UK homes?

Most heat pumps that disappoint aren't a failure of the technology. They were sized from a guess, fitted to radiators that were too small, or set to run at the wrong temperature.

A heat pump works when it's designed around your home's actual heat loss. That's the step that usually gets skipped, and it's the first thing we do.

Check if my home suits a heat pump
  • Cold rooms after install

    A unit sized by rule of thumb instead of a room-by-room heat loss calculation.

  • Higher bills than promised

    Flow temperatures turned up to make up for undersized radiators, which kills the efficiency.

  • Old boiler, rising costs

    A gas, oil or LPG boiler that's due for replacement anyway, with fuel prices you can't control.

  • Unsure where to start

    Radiators, cylinders, controls and insulation. Too many moving parts to judge on your own.

What's Included

  • Low-carbon heating suited to residential and commercial properties
  • Installed by our Gas Safe and in-house accredited team
  • Vaillant and Ideal Heating equipment options
  • Can be paired with insulation upgrades for greater efficiency

Air Source Heat Pump Installation Done Properly

An air source heat pump draws heat from the outside air and uses it to run your heating and hot water, so you're no longer relying on gas, oil or LPG. As MCS certified air source heat pump installers, we design every system around your home's measured heat loss, fit Vaillant and Ideal Heating units sized to your property, and tell you upfront if your radiators, pipework or insulation need attention first.

Because we also handle insulation and general heating work, your heat pump can go in alongside loft insulation or external wall insulation  in the same programme of work. That pairing makes the biggest difference to how much a heat pump actually saves you.

  • Heat loss calculated room by room before we quote
  • Radiators and cylinder upgraded only where they need to be
  • Controls set up for low flow temperatures and efficient running
  • MCS certificate and written warranty at handover

Case study

Air Source Heat Pump Conversion

A semi-detached home converted from a gas boiler to an air source heat pump, with the old system stripped out and a new heat pump, hot water cylinder and pipework installed by our own engineers.

This project took a semi-detached property off gas heating completely. We removed the old boiler and the pipework that was no longer needed, then installed an air source heat pump outside, a new hot water cylinder indoors, and the pipework and controls that tie the whole system together.

Like every semi detached heat pump installation we carry out, it started with a room-by-room heat loss survey. That survey sets the size of the unit and shows which radiators can stay as they are and which need upsizing for the lower flow temperatures a heat pump runs at most efficiently.

We required an urgent new boiler installation due to the old one breaking down and being unrepairable. Greentek Energy supplied and fitted a new one at very short notice so our tenants could have heating and hot water again. We are very grateful to Greentek Energy and would recommend them highly.

What it costs

Air Source Heat Pump Cost

The cost of an air source heat pump depends on your home, not on a price list. A heat pump is sized from your home's heat loss, not its floor area, so we measure that room by room at a free survey and then give you a fixed price in writing.

  • Your home's heat loss

    The calculated heat demand, which sets the size of the heat pump.

  • Radiators and cylinder

    Which radiators need upsizing for lower flow temperatures, and the right hot water cylinder.

  • Siting and pipework

    Where the outdoor unit goes, and the pipe runs back to the cylinder and heating system.

  • Grant eligibility

    How well your home holds its heat. A well-insulated home needs a smaller heat pump, which costs less to buy and to run.

Every quote includes

  • A free site survey, with no obligation to go ahead
  • A fixed price agreed in writing before any work starts
  • Materials, labour and making good, in one price
  • Our own team throughout, with no subcontractors
  • A written workmanship warranty on completion

We don't quote over the phone from a postcode, because the survey is what makes the price fixed rather than an estimate that moves. Heat pump finance is available through Ideal4Finance, subject to status.

Frequently asked questions

How much does an air source heat pump cost to install?+
The cost of an air source heat pump depends on your home's heat loss, the unit size, whether radiators or the hot water cylinder need upgrading, and the pipework involved. We calculate heat loss room by room, then give a fixed-price quote for the whole system.
Is there a grant for an air source heat pump?+
The government's Boiler Upgrade Scheme contributes towards replacing a fossil-fuel boiler with a heat pump for eligible properties in England and Wales. The installation must be carried out by an MCS-certified installer, and we'll confirm your eligibility and the current grant at survey.
Will a heat pump heat my home properly?+
Yes, when it's designed for your home. The unit is sized from a heat loss calculation, and radiators are checked room by room so they can deliver enough heat at the lower temperatures a heat pump runs at efficiently.
Do I need new radiators for a heat pump?+
Not always. Heat pumps run at lower flow temperatures than a boiler, so some rooms may need a larger radiator to stay warm. The room-by-room calculation shows exactly which, rather than replacing everything by default.
How efficient is an air source heat pump?+
A well-designed system typically delivers around three units of heat for every unit of electricity it uses, which is why sizing and flow temperature matter so much. We design for efficiency, not just for the unit to switch on.
Do I need planning permission for an air source heat pump?+
Most homes can install an air source heat pump under permitted development, subject to conditions on siting and size. Listed buildings, conservation areas and flats can differ, and we check what applies before quoting.
Can I spread the cost of a heat pump?+
Yes. Finance options are available through Ideal4Finance, subject to status, and can be combined with any grant you're eligible for.
