We have seen a number of queries about the ability to see all of OVOs current tariff, even if you subsequently have to phone up to choose some or all of them.
Unfortunately OVO don't make it easy. So you have to phone up.
Some providers do let you access some or all of their rates, for example by entering your postcode on their website. Others let you download a document.
For example here is a download of the current price cap rates for economy 7 from EDF.

For Octopus simply enter your postcode at the bottom of this page rather than select the "Get a quote" button.

Then you can see all the current Octopus tariff.
It really isn't difficult functionality to build. OVO have all the data already.
It would really help if there was a self service way of customers seeing the current OVO rates all time, even if customers then had to phone up to choose one of the rates. I am a big believer in self service facilities to free up the OVO Support Team for more serious queries. It is not a good use of peoples time. At some stage hopefully rates will start to fall and some people on high fixed rates may then want to consider cancelling their current fixed rate, even after considering any exit fee.
