Business travel and Covid

I have to attend a meeting in Geneva a week on Monday.

It's in the morning, so I'll fly out Sunday, have the meeting and return to the airport directly afterward, then fly home.

Or - that's how I'd have done it in the old days.

Now I presume that I have to do the following :

• Ensure that I have my proof of double vaccination
  
• Get a PCR test before I fly out
  
• Fill out the PLF stuff
  
• Get another PCR test before I fly back - this is the part I'm concerned about, as I'm assuming I need to wait for the results?
  
• Switzerland is green, which means another PCR test on or before day two of my return
  
  

So! Three PCR tests, two in the UK and one in Switzerland, sound about right?
