I wouldn't stray past £85k unless my interest at end of year pushed it beyond £85k.
Well if you start with £85k and your interest is paid at the end of the year and you reduce the balance back to £85k immediately then your excess is at risk for a very short time.
Presumably if the bank went bust 10 months into your 1 year account......you wouldn't get the interest payment anyway !
The risk is minimal, but as you can avoid it then you might as well.Also many posters on here are chasing best rates, often with relatively small and not well known institutions, so more reason to be safe rather than sorry.
