£200ph does seem to be the going rate these days
The impression I got was that its was a process of elimination by SP's during lockdown to get few clients and also to make-up for loss of earning - but the taste of some extra $$$ can be irresistible they might want to keep the status quo

reminds me of FKK Palace some SP's were over charging as much as €200 for 1/2 hrs instead of the normal €50, when we complained to management - the Manager said its been €50 for 1/2 for years & as the industry is not properly regulated with ie no unions to lobby the government, some girls try to charge what they think is a fair rate ( crazy

) there again the establishment's location attracts mostly newbie's and tourist that will pay the fee without realising they've been taken to the dry cleaners.
