Crap
Crap, sorry. I had to pay for the parking even though I paid £50 for the stupid test which is a blackmail. The system is letting these lot get away with it. Thieves!!!

The service was good but unnecessarily complicated
The service was good but complicated by the royal funeral on the day of my departure.
The service would be excellent if their staff were more proactive in taking your last flight details & working backwards in terms of the 48:hours period. The man who initially served me kept refusing to take responsibility.
If Katalyst had regularly updated software that just required destination & last flight departure time, the best option of next day result or same day or express service could be decided efficiently.
Instead, I initially booked express service (my mistake, which wasn't corrected by their staff) then that was cancelled by the royal funeral & I was advised that a next day service was fine. That meant various phone calls and their need to refund part of my payment.
If the service had been more professional/helpful from the start, this changing of appointments & refund could have been avoided.

All the personnel I met were very…Trustworthy clinic
All the personnel I met were very helpful and friendly. They gave me a great sense of trust. The day I made my PCR test is the day of Queen's funeral where many others clinic in London were closed. But Katalyet Health keep their promise to give me the service. I appreciate it very much.
