If you want your house insurance to be valid it must be installed by a qualified spark.

Iceman is right. New EU legislation was adopted by the UK as of January 1 2005. Anything other than adding a spur to the lighting circuit needs to be inspected and approved by a certified electrician. Also, any work involving electricity and water, e.g. in a kitchen, bathroom, garden etc MUST be actually done by a certified electrician.

"Qualified" is a difficult term in this legislation, since you may be qualified yet not certified. It is the certification that matters.
