I don't know whether this is of any help as I don't know which airport you use! but....
"Airport operator BAA said the new rules on hand luggage, which will allow passengers to take certain items on board, should have come into force at its airports at Stansted, Glasgow, Edinburgh and Aberdeen from noon on Monday.
Southampton airport confirmed on Monday that it has implemented the changes. But BAA said the relaxed rules would not be implemented at Heathrow and Gatwick until Tuesday.
The company says it will need to brief its thousands of security staff, who will not be aware of the change because it was announced overnight. "
Manchester Airport has implemented the changes as of 9am today
