There's a Thaiest FB page dedicated to Thailand ASQs. More info on there than you could shake a stick at!

Olive Health and Travel are in Gants Hill, East London. Guaranteed turnaround but you'll pay between £200 - 250 depending on how fast you want result. The 72 hours is from time of the result to departure. But if you have a connecting flight other regulations may apply eg: Emirates via Dubai- 72 hours from result to departure for Thai requirements but UAE requirement is the test itself must be within 96 hours of departure.

Glad you've sorted it now, mate. Just wanted to say, you were not alone! Reading your post brought back memories of when I spent two days trying to do exactly the same thing! I just downsized everything to the point of not being able to see anything and it was accepted! All the best with the rest of the process.

Is this actually a government mandate issued for all ASQ's? Looks more like something that a particularly risk averse lawyer would draw up for individual hotel(s) wanting to cover their backsides.

I sent exactly the same as you are planning to do. I thought I'd get an email if they required further doc's. After a week with no email I posted all the stuff you have listed only to receive an email requesting further docs (eg, declaration, copy wife's passport and i/d, marriage cert and village book). Personally, I would suggest simply sending what you have listed initially (after all, that's all that they ask for) and then wait to see if they request further details.
