I wish Monzo well with this idea but as has already been mentioned in an earlier post, MSE’s Cheap Energy Club basically does all that for you if you’re signed up to it. I’ve been signed up to it for the last 3 years or so and it’s saved me a lot of time, effort and money.
I can see the benefit in switching energy suppliers, and have used them frequently in the past to my benefit. However, I have a heathy wariness of them as it’s very hard to see why they recommend one provider over another; many/most don’t make it clear whether they receive commission from the suggested suppliers. I can appreciate that for many getting the lowest price is important, but equally there are other less quantifiable factors at play, for example, the suppliers energy sources (green or not), the level of customer service, responsiveness to difficulty in paying, etc.
Linking with just one provider means that this is not a comparison service, it’s just my bank trying sell me energy so they get a £50 bung.
Someone suggested linking to smart meters and I think this could be really powerful. When you enter details into a comparison site it often asks for your last months bill and makes recommendations based on this. If Monzo were to get access to a full year of smart meter data prior to making a switch suggestion it could do so with a much better understanding of how a household uses energy. This would have to be across ALL suppliers making it clear where commission is being paid (and maybe split it 50/50 with the customer?)
I have not been part of the trial so I have not experienced this first hand.
Like @Ordog, I switched to Octopus when it was first trialled, so I thought I would’t see either the previous screens (showing £50) or the new screen (showing £40)
However…
Going back through my Home feed , the item (dated 12-Feb) states “Switch energy supplier, get £50” and if I tap on it, I then get the same ‘£40’ display as the one you’ve posted above.
Now then, which is correct? The initial advertised refund value is £50, but the detailed refund value is £40…
The customer credit you receive from Octopus will soon be changing from £50 to £40; however this has not happened yet and so if you have already signed up, you will still receive the £50 as advertised.
Gas 3.213p kWh (plus 16.8p per day)
Electric 14.858p kWh (plus 20.15p per day)
It’s now even more useful as it allows you to enter your own usage 
(You can add gas & electricity kWh)
And I was right about the new reminder asset 
(that’s when I asked it to remind me)
I cheated to get them to show up 
time
