    I had a one year fixed ISA mature today and the interest was calculated as AER % X 366/365

    The standard interest calculation for current accounts is actual/365 or actual/366. I’d be interested to know which organisations go act/365.25. 
    Hargreaves Lansdown uses this method for calculating their charges and, I think, the (tiny) interest that they pay on ISAs. Yes, I agree that it's a very odd way of doing it, and Iit surprised me when I discovered it. I'm not aware of any others. However, if one firm does it this way, it's possible that others will.
    Seems a weird way of doing things. There are quite a few options for calculating interest and I once saw a USD bond based on act/365 but other than that it's always been pretty standard stuff.
