each different provider has their own protections under their own licences…extremely lazy as it was only 4 clicks away in the create a savings pot section , Time management sir - you could have found out with less effort than creating then typing the query
Monzo and each provider of a savings pot has it’s own FSCS protection and limits, like iansilversides says. You make a claim with FSCS if needed. So, 85k with Monzo, 85k with Charter Savings Bank etc.
To be clear regular pots are just an extension of your Monzo current account. They are not seperate savings accounts. Therefore your main account and any regular pots you may have are all covered by the same FSCS protection (not each pot).
If you have a specific savings pot from an external provider like OakNorth or Paragon, you will also have protection for that pot (or including as many pots from that same provider) separately.
