I will PAT test my own equipment next month. Its quite straight forward to do once you have bought the tester.
I went online and watched a DVD for an hour on PAT testing and then did a 30 question test online. I passed with 29 out of 30. You can then down load a certificate and off you go. They send you a Dvd out as an aid memouir and also can get help nline if you need it. I bought a decent PAT tester for just over 200 quid online including all the labels, record book etc. Job done. Now every Jan I just PAT test the stuff myself or at any other time of year if the equipment needs it
Just do a google I think it cost me about 60 quid to do it. You dont even need to leave the house
