You can exit your contract simply by sending a termination letter to your supplier.

Just ask our Squeaky sales team if you need a hand writing it, but they usually go something like this...

This is for the meter with MPAN number [insert 21 digit number] at the address mentioned above with the last date of supply being [insert final date].
