Any one else taking part in the Office for National Statistics Covid survey. A large OHMS envelope dropped through the door inviting us to take part in the survey. A week later we get a phone call to arrange a visit, a few days later a guy turns up, asks us the usual questions re Covid and we do a Covid test. Apparently we will receive a fifty pound voucher for first visit and survey, followed by twenty five ponds for each monthly test after that.
