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.

- Warm Homes Nest, run for the Welsh Government, offers free improvements to eligible low-income households.

Questions about loft insulation in Cardiff
Is loft work in Cardiff different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Do you take on jobs outside Cardiff?
Yes. We also work in Penarth and Trowbridge (South Glamorgan) and elsewhere in South Glamorgan.
How soon can you visit a home in Cardiff?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
