So I have 2 TMOs which I will share once I get home - but in short, it says prescribed hours - nothing about term time only. Therefore, with Redbridge now covering up the words "Term Time Only", it means that these restrictions are likely to be in place every day - including Christmas Day, Easter Monday.
I do know that not all signs have been removed as some still had the words "Term Time Only" displayed - but I think these will be covered up in a matter of days/weeks.
