Meter, Consumer Unit Wires

[timtheenchanter]

I today discovered that there is a plastic box, about 4"x6", with contacts inside wiring the meter to the consumer unit, the cover is held on by a small thumb screw, is this legal/sensible, as it requires no tools to give access to non-isolatable supply, there seems to be lugs on it for sealing, but no seal there,

Help please

Photo would be good - are the cables simply connected inside?

Is it in the tails before or after the meter?

To me it sounds like a contactor for economy 7 (i.e. old night storage heating or immersion heater) However as mentioned above a photo would be good.
