Gatwick ExpressTest have made some more tests available for Gatwick for this month. I managed to book some tests for my family on Thursday next week. If you need them, don't hang around.
The same company is now offering testing at Heathrow. Cost is £99 or £80 if you have a flight from Heathrow. The ExpressTest drive-through is located on the Northern Perimeter Road opposite the exit to Business Parking (Terminals 2 and 3).
Edit (12/12):Just to add to the fun, Heathrow test centre has disappeared from their web site today!
