Things to check for yourself

• Make sure all your pipework in the loft is properly lagged to alleviate the possibility of pipes freezing
• Check that your storage tank is lagged and has a proper plastic snap-fit lid.
• Check that your loft insulation doesn't actually extend beneath the storage tank. This allows warmth from below to take the chill off the tank.
• If your boiler is in an exposed position, i.e. garage or outbuilding, make sure a frost stat is attached. If not, get this rectified!
• Take extra care with pipes in cold weather. Open the loft door to warm the roof area.
• Have your boiler regularly serviced.
• If you own or are in a rented property, all gas appliances must be serviced annually and the tenant should have sight of an up-to-date Gas Safe Register Landlord Certificate.
• Make sure there is a stopcock on the header tank in the roof.
• Only allow Gas Safe Register qualified plumbers to service your gas appliance.
• Do not allow any unqualified person to touch your gas appliances. They could, if reported, receive a huge fine.
