It will vary depending on cancellations but test centres throughout the UK are generally around 3 weeks. Having said that, I booked some yesterday in Nottingham for today. But that’s unusual. You probably know you can book your own theory tests via the DSA website. If you know your driver number you can keep trying to get your test before you’ve received your licence. It wont make a lot of difference probably but that’s as quick as it can be. The system will allow you to book the test when the licence has been issued - which is a different matter to waiting for it to arrive.
Thanks guys I wasn’t aware I could book without my license.
I’ve not got both theory test and hazard perception booked for the same morning, my license needs to have arrived back by then but that shouldn’t be an issue.
