It looks like the first amendment to BS 7671:2008 Requirements for Electrical Installations may be published on the 1st July 2011 and looks like it will come into force on the 1st January 2012, This does not come as a surprise to me, and I am sure other electricians will also not be surprised!
The IET prepares regulations for the safety of electrical installations for buildings, the IEE Wiring Regulations (BS 7671) now having become the standard for the UK and many other countries.
