English & Welsh Building Regulations Part L2 - Section 3 - Building Log Books
Since April 2002 it has been a duty of the English and Welsh Building Regulations Approved Document L2 for the proprietor or denizen of a edifice to be provided next to a Log-book upon completion of any complex connected to the vivacity bodily process of the property. This may be a new building, the installation of new steam boiler factory or new windows. Subsequent amendments to the Building Regulations have strengthened the requirements.
