Just a word of warning that a company being on the government's list of accredited private test providers is no guarantee that they're legit! I booked my day 5 test to release test with Dante Labs and returned it as per the instructions. This was on Thursday and I was told I'd get the results the following day, i.e. Friday. It's now Saturday and I haven't even received a confirmation of receipt. I called and spoke to someone who seemed to have no clue what they were doing, then later there was no reply at all. Trustpilot is full of negative reviews. Please avoid them!! Clearly being on the gov.UK list means very little! Have now paid £150 for a 24-hour turnaround test as I'm climbing the walls...
