Most travellers will be required to test upon arrival at the airport in Edinburgh, Glasgow, Aberdeen or Dundee . A further test is required five days later and can be done in the St Andrews Walk In Centre. From 8 am to to 2 pm you can walk to the centre and obtain a booking for the same day for a PCR test. After 3pm you can walk in and pick up up to two box of Lateral Flow Tests containing seven tests each. All of this is provided free of cahrge and should hopefully make it a lot easier to adhere to the applicable rules.
