Insulation can make winters cosier and less costly for most home-owners and businesses. The Energy Saving Trust is a good place to look for advice on draught proofing and other energy-efficient home improvements. Landlords can get tax relief and lower rates of VAT on energy saving measures implemented on their properties. Uncontrolled draughts admit too much cold air and allow too much warm air to escape. Draught proofing is an inexpensive way of reducing winter heating expenses.
