About Us

Since 2003 we've been a driver for environmental change in products for the commercial sector.

Green Earth is the UK's leading commercial solutions provider in the fight to reduce carbon emissions. Our mission is to create a world where multinational organisations achieve their carbon footprint goals.

To realise our mission, we're finding ways to help transform the future for the world's commercial buildings; pushing for a reduction in carbon emissions to avoid tragic climate change, and pressing for measures to help organisations conduct business more sustainably, within the means of our earth.

We're acting now to make this happen.

We help commercial sites achieve their carbon emission goals.

Introducing EndoTherm

Save 15% on your heating costs.

EndoTherm is a low cost, high impact energy saving additive that can be introduced into any wet heating system – commercial or domestic, reducing the energy consumption by up to 15%, thus reducing bills and greenhouse emissions.

Save energy. Save money. Reduce emissions.

  • Proven in laboratories to use less gas and energy.

  • Heat exchangers stay hotter for longer, costing less.

  • Systems heat up quicker and more efficiently.

  • 100% Organic and Environmentally Friendly.


With low installation costs, no system downtime, no capital outlay and effectiveness for 7-10 years, the return on investment with EndoTherm is less than one year.


EndoTherm now has more than 200 commercial case studies proving its savings.

Variance between systems mean efficiencies range from 10% to as high as 30%, while on average EndoTherm will save commercial sites 15% on energy and fuel costs.

EndoTherm is the first technology of its kind to be recognised by the Energy Saving Trust as a heating additive.


Patented. Laboratory tested.

EndoTherm has been performance tested by leading, independent authorities including Enertek International, University of the West of Scotland, Uclan and by the Energy Saving Trust themselves. They all agree — EndoTherm significantly reduces both fuel costs and carbon emissions.


How it works.


The inclusion of EndoTherm reduces the impact of steam bubbles, which in turn restrict heat transfer in nucleated boiling sites. This allows the water to heat up quicker and more efficiently.


The improvement in thermal contact area effectively increases the size of the emitter, improving heat transfer efficiency and reduces the boiler operation time for each cycle.


Testing on EndoTherm-dosed systems shows they cool down over a longer time period, increasing the time between cycles and reducing the number of cycles over a given period.


The increase in heat loss from the system emitters reduces the temperature of the bulk water as it returns back to the boiler, allows them to condensate more and recover more heat.


Installed in more than 100,000 buildings throughout the UK.
