Hi all, this is my first post so be gentle! I'm a qualified electrician to the 16th edition, and also have my c&g 2391 (inspection and testing). My girl friends Dad owns a furniture shop and is the landlord of the two flats above it. He requires a periodic inspection and test to be carried out on all three installations. He has asked me to do the job as i'm looking to go self employed so am starting to look into getting bits of work like this as a kick start. So my query is am I legally permitted to carry out a periodic inspection and test, and sign off the certificate if i'm not registered with a specific scheme? Can I down load template certificates from the internet to use? With the shop been classed as a commercial property and the flats a domestic would this make a difference to any regulations regarding 'Part P'? Any guidence at all would be apprciated. Thanks guys.
