Once you switch, Taupia keeps watching the market and tells you if it is worth moving again.
How the estimate works
Enter your postcode and pick your address. Taupia finds the meters, names the supplier, and prices today's market for a home like yours. Both figures use the same usage, so the gap between them is the rate and nothing else.
Switch here, in about two minutes
Pick a rate, add a few details and a Direct Debit, and the switch goes to your new supplier. Nothing is sent until you confirm it, and you have 14 days to change your mind at no cost.
What happens after you switch
Once you are on a better tariff, Taupia keeps watching the market behind the scenes. If a cheaper deal turns up, you hear about it, and nothing moves without you saying so first.
This app was a great tool and introduction for setting up bills. I had no idea what I was doing but Taupia was able to walk me through everything.
