what notice do I need to give ?
You don’t need to give any notice. Just ask another supplier to switch you to them and they’ll take care of it all. We don’t have any exit fees or anything, so there is no penalty for leaving.
@Dylan, despite not having to give any notice, bear in mind that it takes a minimum of 21 days for a switch to a new supplier to complete. This is an industry standard rather than something down to Bulb though.
