Apart from the overly complex and time consuming process to upload the numerous photos needed prior to making arrangements, and that only one fitter arrived believing it was a sub-15 metre cable run (it should have been two fitters because the cable run I had paid for was actually 28.5 metres), the fitting was arranged quickly and was done exceptionally neatly (although it took the single fitter 9 hours on one of the hottest days of the year!). All works very well, I received the certificate by e-mail a few days later, and I am very happy with the final product.
