Hello anyone else had this Email from Paypal.
I have given a full explanation on the Auction Payments Page
As part of our ongoing effort to make PayPal an even safer place for you and your customers to do business, we're holding a percentage of the total payments you receive each day as a reserve in your account. This reserve helps make sure that you have money in your PayPal balance to cover any payment reversals or chargebacks. We're going to start holding 100.00% of your daily sales until you reach a minimum reserve of 102.71 USD.
I know it says dollars but it must also refer to UK as mine are on hold.
