What are the requirements and processing times for applying for a DTV visa at the Thai embassy in London?

Hey everyone, I'm looking to apply for the DTV from the UK later this year using Muay Thai as my soft power.

The general website said 3months of bank statements with the financial evidence but my friend said 6 and as it can vary by embassy, can anyone advise what the London embassy may ask for?

I looked on the website but couldn't find it.

Also how long did yours take to process, I was hoping to apply about a month/6weeks before flying.

What have people been approved for using as proof of current location? I am not on any of the utilities as its a share house

Other than the letter from the gym it says I need proof to attend the activity, does that mean I need to write a confirmation letter or send them a receipt or am I missing something?

Thanks in advance 😊
