• Install solar panels if this is affordable for the company – this is a long-term investment, but will reap benefits & save money over time. You will first need to get an evaluation to check that your building receives a decent amount of sunlight.
• Save energy by reducing the need for heating by insulating the building or checking any insulation that is already installed is up to standard; this will also save money if you can cut down on heating costs
• Efficient air heating systems- heat recovery (‘recycling heat’) systems- help your heating systems to work more efficiently. See here.
• If the building/ space is rented, switching energy suppliers or installing renewable energy technologies might be out of your control, so get in touch with your landlord and start a discussion, first finding out which energy supplier they use (if you don’t already know).
