Update on my DTV application at London embassy. I applied on 29th August and it arrived approved on the 5th September.
In the documents I provided my booked flight was leaving on 2nd September (my mistake), however this was never questioned. So the flight I actually got was on 9th September.
I had a hotel booked for a week, but that was also a refundable / cancellable booking that I never used. I'm now in a condo with a long term rental contract.
I provided a copy of my companies employment contract, recently updated to include some vague details relating to remote work.
I also moved some funds around a few days before applying so I could show the 11k GBP in the bank in an official bank statement (not a screenshot or transaction history).
Seems like the London embassy is still a good place to apply for this visa.
