Notice a chilly draught in the dead of winter? Now that the weather has picked up - it's a great idea to get outside and make sure the areas around your windows and doors are completely airtight.
Small air leaks should be easy enough to patch-up with a DIY silicone sealant. Alternatively if you live in a less well insulated draught proofing your window, doors, skirting boards and floor boards could save you around £25 to £35 a year on energy bills.
