Hi ever one ,may sound boring ,but has any one heard or know any thing about Part P. A really good idea Part P was introduced to protect the public.Unfortunately it has never been policed partly due  to the responsibility being solely hung on local council building control.A hard pressed group.Part P was introduced to protect people like us the public. look up the statistics how many Fires are electrically generated,bad land lords ,cowboy electricians, I think the government has looked at Part P as a way to generate extra income Name address, national ins no, TELLS ALL.Even so just remember if an electrical co is Part P certified with ID you can feel safe.That is NICC  ELCSA  NAPIT All these can be found at www.mylocalelectrician.co.uk which I am a free subscriber.
