As part of the review of the English Building Regulations, which includes the amendments to Part L, The Approved Document to Part K is being changed to incorporate the guidance given in Approved Document N and the stairs related parts of Approved Document M. A consultation document has been published in a new format for Approved Documents which sets out the guidance in a clearer and more accessible way. Under this review the new guidance applies to England only as Building Control powers for Wales have been devolved to the Welsh Assembly.
