I one I have makes a very quiet beep (you can rarely hear) when the credit runs out, & to use the emergency you have to remove & reinsert the key
Quiet!!!!!!
Lucky you, you must have a broken one.
I'm starting to hear it when I'm not at work lately.
(Could be tinnitus
)
You have to remove/insert the key so the meter knows you know it's going to run out.
Lots of people are quick to complain about the key meter.
It does have benefits over over prepayment types tho.
One is that if they run out of the EMERGENCY credit, and the paypoint's are closed (ie you can't go and top up) the meter will still let you have electric until the Paypoint opens they next day.
It also thinks all shop's are closed on bank holidays and sunday's.
And I usually fit them for elderly people (like my mum) who like to top up when they get their pension etc and not have to worry about a big bill droppin through the door, or People who don't like paying bills get one with a debt set on it so they can pay the debt off over time.
Back on to topic........
If it's the metering company that will be moving your meter a couple of inch's down your board don't expect them to fix your board to the wall.
I pass them to mains, I don't want to be moving the cable more than I'm paid for.
Tell mains that the CUTOUT is hanging off the wall and they should be round same day to sort it( work depending of course
