I too get thoroughly fed up off the way the system works (or rather doesn't work) these days!!!! I have quite a few occasions when I have had to get the POCO to either do a temp disconnect or change to PME and it is almost impossible to do it easily. In fact one elderly customer called me 12months after I had arranged with British Gas to change his tails, to ask when they were going to do it!!! If anyone knows how to get round this mish mash of a set-up I'd love to know. As to the BS 3036 service - I have seen those years ago, usually in a metal enclosure, very rare these days.
