I have also managed to book this morning! Firstly I tried after midnight and slots appeared for September. But I needed for August so checked again this morning at about 10.30am and 11am and there were slots for August in Glasgow, Sheffield and Croydon. They disappeared pretty quickly but I managed ...

I have been trying since last week to get an appointment also. I have called them today and they say there is no issue with the booking system. But it sounds ridiculous not to have any single slot for the whole country for the next 45 days. Has anybody managed to book any slot recently?
