The DVSA – the agency overseeing driving tests – has confirmed as of 20 March that driving theory tests have now been suspended for a month while practical tests have been halted for three months with immediate effect. More information and further updates are available on the Gov.UK website
“A testing service will still be available to those who have a critical need, such as the NHS and drivers delivering goods across the UK,” a DVSA spokesperson told us. A specific email address for those seeking an emergency theory or practical test is available at the site linked above.
If you don't meet these criteria and your theory test has been cancelled you'll get an email and a refund, though the site advises this may take a few weeks to come through.
If your practical test has been cancelled at short notice and left you out of pocket you can apply for a refund of "out-of-pocket" expenses - see the link on the Gov.UK website above for more. Either way, you will get an email offering a new test date, likely to be around three months after your original one. Confirmation of this may take some time to come through and the DVSA advises the customer care line will not be able to help with questions relating to this. Alternatively, you can cancel your test altogether and get a full refund - to do this you'll need your licence number, your theory pass certificate number and your test booking reference.
No bookings are currently being taken for driving tests and, when they do recommence, priority will be given to those who had theirs cancelled so it may well be in your interests to accept the revised date in the first instance. Note that if your theory test expires before that you'll need to do another one so you arrive at your practical with a valid certificate.
