Questions about pipe and tank lagging in Cornwall
Which council covers my address in Cornwall?
Councils in Cornwall include Cornwall and Isles of Scilly. Your council matters for building control questions and some funding schemes.
Are your prices the same across Cornwall?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.
Is pipe lagging included with loft insulation?
Yes. A tank jacket and pipe lagging in the loft are included in every loft insulation and top-up price. If you only need lagging, it is priced on its own.
Should I insulate under the water tank in the loft?
No. Leave the ceiling directly under the tank uninsulated so a little warmth from the house reaches it. Insulate the top and sides instead.
