Building regulations in Wales
Wales has its own Approved Document L under the Building Regulations 2010 as they apply in Wales. Insulating more than half of a loft counts as renovating a thermal element and must meet the Welsh energy standard. Insulation alone is not normally notified, but rafter insulation that is part of a conversion is building work that needs building control. We confirm the route for your address on the quote.
