@Tommy My sub was £5/month for 3 months, which started on 16 Sept. BKOOL states "Your current renewal price remains the same for the time being. If anything changes, we will let you know in advance." So I expect to hear something either when BKOOL retires on 30/11, or in advance of my subscription ending on 16/12.
UPDATE. Just got an email from Rouvy saying that they will give a 50% discount for 2 months. It would be cheaper to join a group of 4 or 5, and split an annual subscription. I don't know what happens if one wants to pause over the summer. Although with the cost shared, keeping it going would not be too expensive.
