Hi Gary, You can also check the website below.This will also tell you if the person is actually registered and to which organization they work under i.e NICEIC,NAPIT etc. As Matt says If they are governed by an organization you can complain to them and they will take it up on your behalf. If they are not registered you would perhaps need to go to trading standards electricalcompetentperson.co.uk Thanks Russ
