got this from another forum
London Visa Office Status:
Processed AOR
June and Before = 99%
July AOR = 80%
August AOR = 60%
September AOR = 45%
October AOR = 20%
November AOR = 10%
December and after = less than 10%
London is processing applications in two batches. Firstly, October then August. Secondly, November then September. They will process 80% of Nov AOR and 60% of Sep AOR by the end of April. The standard trend in London nowadays is as follow:
1 month from AOR to R10 Pass
2 months from R10 Pass to CIO Decision
3 months from CIO Decision to LVO Decision
1 month from LVO Decision to Background Decision (unless Security Screening)
1 month from Background Decision to PPR
