A cheaper Smart Pay As You Go plan

Our Smart Pay As You Go plan reflects the true cost of energy, so you’re always on our best deal. And we don’t believe in fixed-price contracts or exit fees, which means you’ll never pay a loyalty tax by sticking around. You need a compatible meter to switch to this plan.

Top up online, with the Bulb app, or in store

It’s easy to top up online, or with the Bulb app. But we’ll send you a card too, so you’ll always be able to top up at one of the 28,000 PayPoint stores if you prefer. And if you don’t have a smart meter yet, you can switch to our traditional Pay As You Go plan.

We’re rated excellent on Trustpilot

We're easy to get hold of by phone, email or online chat. We don't like to toot our own trumpet (so it's lucky that our members do it for us).
