Do I need a RT PCR test to transit through Dubai from Phuket to the UK?

I asked this question a couple days but didn’t get a clear answer. Do I need to do a RT PCR test before I leave Phuket to transit through Dubai back to the UK?

I have tried phoning Emirates many times and just been left on hold and I can’t find no clear information on there website. I know in the uk they do not require you to show a RT PCR test but just fill out your passenger locator form before I depart Phuket.

Can only people who have recently traveled from Thailand to UK with a stop over in Dubai comment and tell me if they had to show proof of a RT PCR test before departure.

Many thanks 🙏
