Do I need to pre-book a PCR test before flying from Bangkok to the UK via Singapore?

You will need to book an arrival day 2 pcr test and then use the reference number for your passenger locator form. Also you need an covid test antigen or pcr in Thailand in the previous two days before departure. With a certificate. For transit changi and uk regulations

I recommend booking with Randox on arrival who are at the airports. Took me 5 mins after exiting baggage area at Manchester and then it was done and didn't need to worry getting to a testing center in the next 2 days.

All I want to say is that people must be a sandwich short of a picnic to go to Thailand for a holiday knowing the hoops and cost just to get back into the UK. My rant over.

Randox home test kit, for day 2, probably cheapest at £43 with discount code. Just check there is a drop box near you. Can use any discount code

You need a pcr or antigen test to board your flight back to the Uk, you need a day 2 pcr test booked for when you arrive back in the Uk. This must be booked and paid before you leave for the Uk as the code you get needs to be added to your passenger locator form which you need to complete from 48 hours from your departure time to the Uk

Well I've just started a thread in the UK group. Absolutely steaming with these providers back in tbe UK, thieving bastards. £15 my arse.

Not trying to de rail the thread as I will be travelling back next week myself via Singapore. I'll be doing a PCR in pattaya somewhere within the 48 hr window.

Go to the gov.uk website and find out

Also transit singapore normally needs test

Been a few posts last couple of days about regulations for flying back to UK.
