What documents are needed for a Workcation Visa in Thailand, and how long does it take to get approved?

Was issued a my DTV a few days ago and just wanted to update the group as I found a lot of the info on here helpful. So hopefully my experience might help others when applying.

Applied for the visa at the thai embassy in London on 8th of Dec (Sunday morning). Went with workcation visa based on remote work. Submitted the usual docs. Passport, photo, used driving licence for proof of location, bank statement with 500k thb (statement dates from start of Dec to the 6th), and a letter from my employer confirming that they were happy for me to work remotely and they support my application.

On Monday they asked for additional docs. They wanted a better copy of my passport and photo. Plus a copy of my work contract and an e-ticket showing my name and departure dates from the UK. My work provided a temporary flight reservation but never confirmed the booking, which I thought might be an issue and I supplied the rest.

On Thursday afternoon I received my 5 year visa.
