A bit of good news to start this article - in the UK, there is no danger of the gas or electricity being cut off, even if you take time to sign up!
The utility companies never cut off supply (except in extreme circumstances), and the system is designed so that new tenants have time to choose a new supplier and/or switch the new gas or electricity contract in their name.
However, that does not mean you should delay. You should sign up for your own utility account as soon as is practical. This is because utility bills are invariably required as proof of address, and so it is very handy to have them in your name.
