Insulate your loft space

In an un-insulated home, you could be wasting as much as 15% of your heating costs and releasing an extra tonne of carbon dioxide (CO₂) into the atmosphere unnecessarily. Insulating your loft or adding another layer on top of your existing insulation isn't very expensive and could save around £200 on heating bills every year, year after year. The recommended depth for mineral wool insulation is 270mm, which is about 10 inches. [Source: Energy Saving Trust]
