From Monday, April 6, 2020, the RSGB started handling bookings for remotely invigilated online Foundation amateur radio exams that people could take in their own home, since then 3,000 people have passed Foundation

On 7th March 2021, the RSGB made this announcement on Twitter:

Prior to last April only around 1,350 people would pass the Foundation each year , the availability of exams to everyone, regardless of where they live, has led to a welcome upturn in numbers.

The previous exam system was essentially club based but the problem was only a minority of clubs were able to provide Foundation training and exams. This often resulted in would-be amateurs having to travel large distances to find training and to take the exam. This resulted in some parts of the country having virtually no new radio amateurs due to the difficulties in accessing training/exams.
