All the previous bad reviews reflect our own experience - test results often delayed by several days and we are now certain the Royal Mail is not to blaim. My day 5 early release result arrived in the night between day 7 and 8 and my wife is still waiting for hers (day 8+) - in the meantime she has already submitted her day 8 sample. This company doesn’t appear to be able to handle the current demand for tests (if they ever have….). Best avoid and look for a different provider.
