As above..
I rented a small flat many years ago..
It had a card meter,i thought it rather expensive, i later found out i was paying off the owners 400 quid unpaid leccy..
I suspect you will be fine if its in the contract But evidence can be priceless when dealing with utilities
We always insisted on a meter reading by someone in "authority" whenever going into a new property
When in Quarters it would be the guy handing over the property, or when renting it was the Landlord.
When we bought our house, it was the Estate Agent selling the property when the keys were handed over.
Then a letter to the provider with a copy of the statement and a request for a formal edging or record of the starting figures.
