Sorry if I’ve missed it (A lot of comments on here) but if you all take a look at IFTTT they have the 1p savings challenge on there! An automated thing which will transfer the money to a pot for you.
Also, even better news, Plum now works with Monzo! https://friends.withplum.com/r/2NNg86
Give the link a click and sign up to Plum. They also now do Investments. It’s helped me save a decent amount over the months.
