Rules that apply in Southport
- Building regulations
- Insulating more than half of a wall, or more than a quarter of the whole building envelope, counts as renovating a thermal element under the Building Regulations, so the wall should reach 0.30 W/m²K where that is technically, functionally and economically feasible, and building control must be involved.
- VAT
- Installing insulation in a home is zero-rated for VAT until 31 March 2027, then 5%.
