Without adequate attic insulation you are losing energy and money through your roof. If your attic insulation is currently less than 250 mm, you should add further layers. There are a variety of suitable materials including mineral wool, rock wool, sheep’s wool, polystyrene, cellulose fibre and multi-layered foil. The water tank and pipes should also be insulated to prevent freezing. The area under the cold water tank should not be insulated.

Check the attic hatch or door for cold draughts and, if required, seal with draught proofing to prevent heat escaping.
