This a terrible idea, I thought Monzo was a bank.
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.
