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 Monmouth
Do you charge extra to travel to Monmouth?
Not normally. Our guide prices include normal travel to Monmouth. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can you visit Monmouth outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Is loft work in Monmouth 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.
Will I get a written quote for work in Monmouth?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
