Yes, you can switch to Bulb. We have a simple join form that will get you on your way.
To sign up using a referral link, just add 'quote.' in the URL before the referral link so that 'bulb.co.uk/refer/example123' becomes 'quote.bulb.co.uk/refer/example123'.
We're currently in a beta for traditional prepayment meters. You can read more about it in our Community article.
We're not quite ready to take Smart Prepay meters. If you have one and want to switch to Bulb, we’ll have to switch the meter to credit. This means you would make a fixed monthly payment, taken in advance.
