I have been asked to do some testing where others have done some installation - I always explain that I can only give it a PIR because I did not do the installation and therefore would not issue a EIC. Done a job where this happened because the electrician did a runner ( but good electrician, some personal dispute). Anyway I did a PIR and LBC will not accept it. I don't see how we can overcome this without cheating. Any ideas, oh wise ones!
