approved by a member of the EEA (e.g., DIN/VDE 0100); guidance given in installation manuals that are consistent with BS 7671, such as the IET On-Site Guide and IET Guidance Notes Nos. 1 to 8. In Scotland, the Building (Scotland) Regulations 2004 apply. Installations in commercial and industrial premises must satisfy various safety legislation, such as the Electricity at Work Regulations 1989. Again, recognised standards and practices, such as BS 7671 "Wiring Regulations", are used to help meet the legislative requirements. Regulations All new electrical work in England and Wales within a domestic setting must comply with Part P of the Building Regulations first introduced on 1 January 2005, which are legally enforceable. One way of achieving this is to apply British Standard BS 7671 (the "Wiring Regulations"), including carrying out adequate inspection and testing to this standard of the completed works. British Standard BS 7671 (the "Wiring Regulations") is not statutory, thus someone doing electrical work is allowed to deviate from the wiring regulations to some degree, but it is generally accepted that it is best to follow the wiring regulations to the highest standard possible. Electrical work does not have to be compliant with BS 7671, but if a casualty or fatality occurs as a direct result of that electrical work, and this results in a legal action, then it may be necessary to justify major deviations from the principles of BS 7671 and other appropriate standards. Some of the restrictions first introduced with the 2005 version of Part P of the Building Regulations were highly controversial, especially the rules surrounding work carried out by unregistered electricians, builders and DIYers. Under the new regulations, commencement of any work other than simple changes became notifiable to the local building control authority; "other than simple" in this context meant any work in a kitchen or bathroom other than like-for-like replacement, work in other areas more than just adding extra lights or sockets to an existing circuit, or meeting certain other criteria, such as outdoor wiring. To coincide with the new regulations, the Government approved several professional bodies to award "competent persons" status to enterprises which meet the minimum agreed criteria for Scheme entry. Scheme membership allows an enterprise to "self-certify" work that they carry out without the requirement to have undergone any formal installation training or to hold relevant qualifications in electrical installation practices - since practical competence can be
