Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This one, about how close a consumer unit has to be to the supply company's meter, is answered by MK Electric:

Answer: Consumer units should be installed within one meter of the supply energy meter. However, you may extend this to two meters without any dim views!
Installing a switch fuse rated to less than the main service cut out would enable you to install the consumer unit some distance from the main service.
