I need to turn the electric off at the meter??

[Gpxbiker]

I am having a sub meter installed in a property (to separate out cost of the hallway lighting and a flat). An electrician has been to the property and told me there is no isolation switch after the meter to turn the power off. He said the meter is a liberty 100 and the manufacturer should have a code to do it. The manufacturer told me there is a code but I need to contact my energy provider. My energy provider has told me it’s a job for an electrician.

I feel I’m running in circles and not sure what to do. So thought I’d reach out here and ask if anyone knows if there is a way to kill the power in order the let the electrician to install a sub meter before the consumer unit but after the meter?

I have to say that even if there is a 'code' which enables one to switch off the output from the meter, I would personally not want to trust my life to that being an adequate means of isolation if I were working on things downstream of the meter.

If one forgets new-fangled meters, the traditional approach would be to get the DNO to remove their supply fuse, making the whole installation 'safe' and then replace the fuse after the electrician had done his work. It would be sensible if, at the same time, the electrician also installed an isolator (after the main meter), so that you never have the same problem in the future.

Kind Regards, John

Option 1 - have a separate metered supply installed for the hallway and whatever else, which will then have it's own meter and will be billed individually by whichever electricity supplier you choose. Circuit(s) for that will need to be in the own entirely separate consumer unit. This is the appropriate choice is the flat is being rented to someone else, and that someone is the person who will be paying for the electricity in that flat.
If you want this, then the process is to contact the network operator for your area (NOT the electricity supplier) to have a separate service cutout installed and allocate an MPAN for the new supply. You then contact an electricity supplier of your choice to set up an account and install a meter.

Option 2 - if this is just for your own use, such as you living there and you just want a separate indication of how much the hall lighting uses, put that lighting onto it's own circuit if it's not already, and install a kWh meter in the consumer unit for that individual circuit. If no space in the CU, the meter can go in a small separate enclosure. This is a typical example of such a meter: https://www.cef.co.uk/catalogue/pro...-rail-mounting-with-lcd-display-single-module
No need to do anything with the existing meter or supply as it's installed in or after the existing consumer unit.
