Sounds like 0.25%. The rates on many ISAs and savings accounts drift down to these sorts of levels (I saw one recently paying 0.01%!) in the hope you don't notice or can't get round to changing your account.
I don't see any case of misselling if that's what you are wondering.
It's time to shop around and get something nearer 1%- that's another £75 a year.
The best rates are not normally ISAs now but if the tax free interest is important to you because you have significant interest income from other accounts then maybe an ISA is still attractive.
I vaguely recall you posted something similar quite some time ago.
