My metre set up is HUGE Its mounted on even larger backing board. There is the box that comes from outside, mounted on a board that is 12 inches wide by 18 inches high ... next to that is a tiny metre (digital) that is connected to a frame that is 14 inches high by 18 inches wide. Followed by a fuse box. I have just been getting some new kitchen units, and cannot fit the one over the meter, as it would take up almost the entire 1000mm unit. What can I do?

Have it moved. In theory you need to talk to your electricity meter supplier. I say in theory...

You have to speak to your supplier.
Our electric meter is on the wall of our garage, 9 or 10 feet off the ground(just sat in the middle of the wall:loopy:) obviously it causes problems when they come to read it/we need to read it. Some of the readers won`t even attempt to look at it, so for years it was estimated.
We asked them to move it and they quoted us a fortune to shift it. Apparantly its suppliers responsibility till it goes on your property, your responsibilty from the meter to fuse board but the bit inbetween is very complicated.:confused:
We decided to leave it where it was.
