Can I return my test to you over the weekend or a public holiday?
It is always safest to hand deliver or courier the sample directly to the lab in London, especially over the weekends and on Bank Holidays.
We provide Royal Mail 24hr tracked return envelopes for your sample but Royal Mail has early last collection times on a Saturday and does not deliver to the lab on Sundays or public holidays. The Covid-19 test kit specific weekend collection times printed on some priority postboxes do not apply to private Covid-19 test kits.
If you need your sample to arrive at the lab on a Sunday or Public holiday then you should drop it off in-person or use a same-day courier.
If you post on a Saturday morning before last collection - your sample should arrive in the lab on Monday morning.
If you post your sample after last collection on Saturday or on a Sunday - your sample will not be collected until Monday and will not arrive in the lab until Tuesday.
On Bank Holidays samples posted after last collection on Saturday will not be collected until Tuesday and will arrive in the lab on Wednesday.
