Yes, provided it's a tariff we can switch you to. Like all energy comparison sites we're paid (though unlike others, we don't hide tariffs that don't pay), and also we chose to give you cashback (£20 dual fuel, £10 single fuel).
You wouldn't get this going direct (not that all deals are available directly anyway), so it's a win-win. The rest helps cover our substantial costs and hopefully makes us some profit.
For full disclosure, £10 per fuel is slightly lower than we’ve paid before. We usually aim to give you back around half what we’re paid for the switch, but we’re giving slightly lower right now as the market is so volatile. Hopefully we can increase this in the coming months.
