With advanced technology and our skilled, accredited engineers, we install high-quality air source heat pump systems that keep your home warm for less. Every installation is tailored to your property and carried out to MCS standards.
With a high coefficient of performance (COP) and DC inverter technology, our heat pumps deliver efficient heating and hot water using a fraction of the energy of conventional electric heating.
Rated A+++ under the ErP energy-efficiency standard, our heat pumps offer some of the best performance available, helping to lower both your energy use and your bills.
Brushless DC inverter fans, dual shock-absorption mounting and multiple sound-insulation features keep noise levels as low as 42 dBA so your heating runs quietly in the background.
Manage your system from anywhere over Wi-Fi. Our integrated CAREL and CGK control technology lets you control multiple units from a single panel, with simple, intuitive operation.
A built-in PID intelligent defrost mode automatically detects when defrosting is needed and switches over seamlessly reducing energy use and keeping the system running smoothly through winter.
A DC inverter compressor adjusts to the outside temperature, maintaining strong heating performance even on cold days, with heating capacities from 6 kW to 32 kW to suit homes of every size.

An air source heat pump is a heating and hot water system that draws warmth from the outside air and transfers it into your home. It's an energy-efficient alternative to a gas boiler or electric heating and it works even when it's cold outside.
A refrigerant in the heat pump absorbs heat from the outside air. A compressor raises that heat to a higher temperature, and a heat exchanger transfers it to your home's heating system and hot water cylinder. Because it moves existing heat rather than burning fuel, it delivers far more energy than it consumes.
The heat pump unit sits outside your home in a suitable spot and connects to your hot water cylinder and, where needed, a buffer tank. From there it feeds your radiators or underfloor heating. Our engineers handle the full installation and talk you through how to get the best from your system.

There are real, lasting benefits to installing an air source heat pump:
A temporary uplift to £9,000 is available from 21 July 2026 for eligible off-gas-grid homes that rely on heating oil or LPG. Most gas-heated homes remain on the £7,500 grant. Installations also qualify for 0% VAT.
How efficient are heat pumps? Very. Heat pumps typically reach 300–400% efficiency (a COP of 3–4), meaning they produce three to four units of heat for every unit of electricity used.
What are the benefits of a heat pump? Lower energy bills compared with fossil-fuel heating, reduced carbon emissions, and a long service life — typically 15–20 years with proper maintenance.
Eligible applicants include:
We’re giving customers who install an Ideal heat pump free electricity for the whole of December 2025, saving you approximately £200 (usage and savings may vary). This saving is based on a heat pump usage of 541 kWh, 23% off-peak consumption, 2,700 kWh Ofgem average annual electricity usage, average December usage 10.1% and based on Standard Variable tariff rates that apply from 1 October 2024 to 31 December 2024.
This includes 4 in-person services and 3 remote services. If a remote survey flags anything concerning, Ideal Heating will perform an in-person service free of charge.
As of October 2024:
Market value of in-person services = 4 x £225 = £900
Market value of extended warranty = £250
Total value = £1,150
A typical customer can save £164 per year versus the current single-rate price cap tariff. This is based on the following; Savings are based on a customer using Ofgem’s typical domestic consumption of 2700 kWh electricity and with heating provided by an ASHP with COP of 3.1 providing equivalent heat to that from a 94% gas boiler using 11,500 kWh of gas.
This is dependent on what system you’re replacing. To check the efficiency of your system, visit Product directory – MCS (mcscertified.com).
