That’s a very vague question. Why are you interested in whether other people are granted or refused a visa?
The refusal rate is normal and is in line with previous refusal rate, if not lower.
One possible explanation that it seems higher is that previously there would be a lot of short visit/family visit/tourism related visas, which have a much higher success rate. With these no longer being issued during the pandemic, the rest will be purely for work, study and join family. They surely will have a higher refusal rate than short visits.
If you want to see London’s decisions, just ask them.
