Royal Mail

If you are posting back via our Royal Mail pre-paid box, please ensure you seal the contents in the box securely and make a note of your Royal Mail tracking number from the front of the box.

Post your sample in one of over 35,000 specially selected Royal Mail priority post boxes you can find by clicking here. (Services near you | Royal Mail Group Ltd)

We recommend posting before 12pm for first collections. All our PCR test kits are issued with pre-paid First Class postage, which means if you return your swab sample by post in the morning, we should receive it in our lab the following day. The samples are delivered by Royal Mail to our Manchester lab usually around 12pm. Please note that Royal Mail services do not operate during weekends and bank holidays so if you return your swab then, your test kit will be received by us the next working day. If you post your sample on Friday, Saturday or Sunday, your sample may not arrive at the lab until the following Tuesday or Wednesday.

Your UKAS certified results certificate will be emailed within 24 hours of your swab being received at our laboratory (certificate also available for download from our online portal).

Christmas Weekends & Bank Holidays 24-28 December, 1-3 January

There will be no Royal Mail pick up or delivery on these dates and we recommend using our drop off sites or a private courier.
