Tick tock.
Octopus’s prices aren’t changing til midnight on Saturday 2nd in any case - and I’m pretty sure that you can backdate the date of a reading up to 5 days (maybe more?) on their site, so you’ve got all next week to get the reading in.
More info (and slightly more accurate info at that) on this for other octopus customers: prices change from 00:00 (midnight) on Saturday, indeed, but that means in about 2 hours and 20 minutes from now (I’d assumed 24 hours later, erroneously).
However if you submit them a reading taken on Saturday (on Saturday, or up to 5 days later*) they will apply it from that time (ie the beginning of Saturday) at the old rate. So you can effectively get your Saturday usage (up to the point of reading) at a discount to the then applicable rate.
* I’m not 100% certain about the 5 days later, so for safety read and submit on Saturday.
