Only half joking. Guessing that returns on large amounts of cash in retail banks are utter shite, plus the faff of having to limit the deposit sizes to whatever the FSCS limit is. Whereas bung it all in PBs, no worries.

Is there not such a thing as a term deposit over here where you bung in a chunk of cash and get paid over the normal rates for it? No idea about bonds other than 007.
Saving for house deposit, chunk of cash, where to put it to earn highest interest (leaving it as cash, ie. no shares or any weird shit)?
