I believe this to be a quite normal practice. When a house is empty the meter is removed so that no monthly standing order bills are incurred. This was the case with our house, purchase d eight years ago.
On the day we moved in the electricity board installed a new meter and registered the property in my name for future bills. There was no charge for this, and it was arranged by the estate agent.
Note, I live in a village, towns may well have other systems in place, but the. Principal should be the same.
