Please note: Royal Mail DOES NOT deliver samples to our lab on Sunday or Bank Holidays.
e.g. If you post your sample back to us on a Friday, we won’t receive it until Monday.
If you post your sample back to us on a Saturday, we won’t receive it until Tuesday.
Therefore, if you are travelling on a Tuesday or Wednesday and require a test in the 72 hours before you travel, you should consider using a guaranteed courier service to return your sample to us as Royal Mail won’t be a suitable option for you.
