Clade has a history stretching back 36 years, when the founder started a family business servicing refrigeration plant. The business, then known as A1 Engineering Services, grew steadily in both revenue and expertise.

Growth accelerated under the leadership of the current Managing Director adding manufacturing capacity and moving into natural refrigerants. Over the next few years Clade manufactured and deployed over 500 natural refrigerant products across the UK.

As the heat in buildings challenge became clearer Clade began the R&D for a new range of heat pumps which would provide a solution for a growing market. The first heat pump was installed in a Co-Op store and achieved a staggering SCOP of 3.7. The rebrand to Clade in 2021 and expansion of the leadership team cemented the move into the heat pump market.

Clade Timeline


Through integrated refrigeration and heating solutions Clade’s R&D team are leading the way in the use of reduced energy, low carbon products combined to supply heating and cooling. With the close coupling of CO2 plant and heat pumps using the same refrigerant the company is developing a range of solutions which are suitable for all sectors, from agriculture to food retail.

With its internal R&D team based at Clade’s Technology Hub in Leeds the company is available to advise its customers on the latest legislative changes. The Clade R&D team are on hand to support the early stages of any project’s development, through feasibility to a finalised design, supporting the customer through the complete product or project journey.


In order to reach the UK’s Net Zero 2050 target, heating emissions will need to reduce by 95%. All users of fossil fuel heating will have a similar target. Decarbonising heating offers substantial carbon savings that will contribute towards this net zero target. Through the use of its CO2 heat pump technologies, the company offers a range of solutions to support decarbonisation throughout the UK.

Through the close coupling of refrigeration and heat pump heating technologies, it is possible to further reduce carbon emissions. Clade has rapidly become a specialist in this area and has taken huge strides to deliver this technology to all parts of industry, including sectors as diverse as agriculture, food storage, the built environment and food retail, to name but a few.

With ability to design, manufacture, install and support, the Clade team is well placed to help customers equally with both their refrigeration and heating requirements.

Clade Engineering is able to provide heat pumps as either air, ground, or water source. The most suitable type of heat pump depends on several factors related to your property. Generally, air source heat pumps are the most popular because they have the fewest requirements to install. Any type of heat pump can provide hot water and heating to your building.

Heat pumps using CO2 refrigerant as the heat source are friendly to the environment because the CO2 they use stays contained within the appliance and does not get released into the atmosphere. Furthermore, the CO2 we use in our heat pumps has the lowest global warming potential (GWP) of 1 compared to 1000’s for other refrigerants which will all significantly reduce the carbon footprint of your building.

Clade are the industry leaders in heat pump technology. As the heat in buildings challenge became clearer, Clade began the R&D for a new range of heat pumps which would provide a solution for a growing market. The first heat pump was installed in a Co-Op store and achieved a staggering SCOP of 3.7. We have over 36 years of experience and all of our systems are designed and manufactured in the UK.

Our heat pumps meet environmental standards by using a natural refrigerant like CO2. It has a Global Warming Potential (GWP) of 1, which reduces both cost and emissions.

Clade offers a full start to finish heat pumps solution. Our team of engineers design your system, manufacture and supply your heat pumps from our product range, our installation team ensures your heat pump is fully functional and our after sales support team provides ongoing maintenance. You can pick and choose as many or as few of our services to suit your requirements.

We ensure that your heat pump system continues to function. Our heat pumps can generate heat from 50kW to multi mega-watt, with a maximum water temperature of over 80 degrees Celsius and a minimum external air temperature of -20 degrees Celsius. Each of our heat pumps also comes with total cooling recovery to ensure a high quality of continued functionality.
