Air source heating and cooling for our net zero future

British Land has committed to achieving a net zero carbon portfolio by 2030. As part of this transition, we are testing low carbon technologies and have proved that air source heating and cooling works effectively in major commercial buildings: reducing gas use by over 80%, moving away from fossil fuels, cutting energy costs for customers and making workspace more comfortable.

Air source heating and cooling is a renewable energy technology which uses outside air to heat and cool buildings. We started testing this technology seven years ago; at the time, there was apprehension across the industry about whether air source pumps would work for the UK, where commercial buildings traditionally use gas boilers. We went out of our way to understand the equipment, including its limitations.
