Planning and safety in Wales

Wales

Bedroom and escape windows

Wales has its own Approved Documents under the Building Regulations. Approved Document B for Wales sets out escape window provisions for dwellings broadly in line with England's, including minimum opening sizes. We only fit grilles over escape windows with a keyless internal release.

Grilles in rented homes

Under the Renting Homes (Wales) Act 2016, landlords must keep dwellings fit for human habitation, which takes fire hazards into account. Grilles over windows a contract-holder may need for escape should open from inside without a key.
