How long does a switch take, and what happens next?

It depends on the service. Energy switches should complete within five working days of your new supplier receiving the request, unless you've chosen a later start date. Broadband providers will confirm your switch date, and there may be a short changeover. Updates from helloBill and your new providers land in your inbox (keep an eye on spam). Once you're switched, your new providers handle billing, any meter readings and your service directly with you.
