I ordered my day 5 Test to Release kit from Confirm Testing. There are now so many providers out there but I wanted to purchase the kit from a reputable provider that did not charge such an extortionate price. The testing kit was reasonably priced and the kit was delivered quickly and efficiently, in fact days prior to my arrival back in the UK. The results were received back just as quickly on day 6. I only wish I had purchased my day 2 and 8 tests from Confirm Testing too - the day 2 test I purchased from another provider was delivered late (on day 4) and at the time of writing (day 6) I still haven't received the test results back! I wouldn't hesitate to recommend Confirm Testing for travel/fit to fly COVID home tests.
