Charities expecting a hike in energy costs can turn to HeatingSave's smart microprocessor controller to cut heating bills and save money. The premises of small businesses are sometimes more 'variable occupied'. HeatingSave Small Business automatically drops the heating when buildings are unoccupied, so all the more reason to install it. Even if your heating bill is only £2,500 per annum you could still be looking at a payback of less than three years, and much sooner if the cost of energy goes up further.
