Totally agree with Stevels4, stick to what you know. If you are not lv authorised then you should not be messing with the the dno's system, whether you think you are capable or not. Having said that I still don't think that dnos are being awkward, as I have said before it was a regular job for me to isolate an installation for the sparks, sometimes calling back later in the day to re-connect, and there was no charge as far as I know. That was with ENWL. Of course, you can always just take off the meter terminal cover and drop the tails out, nothing to do with dno then!
