Dec 01,2021What a dreadful customer service experience. I ordered a product from Rainbow Labs and cancelled the order after 15 minutes in line with their cancellation policy. They have now charged my credit card and dispatched the order despite numerous attempts to contact them. Not having a working phone number is a massive red flag. I have wasted a lot of time chasing this up and sending numerous emails and now having to get my bank involved to raise a dispute. AVOID!

Nov 30,2021Never received anything not even a reference number for the locator form although they took the money. I’ve emailed them several time re a refund but have received nothing. Definitely would not recommend this company.

Nov 29,2021It took them 36 hours to send me my test certificate, long after my scheduled flight departure and much longer than the 6 hours they say on their website. I emailed support twice and received nothing aside from '"it's coming soon." The first time I used their service, the certificate came in 3 minutes. Unreliable...

Nov 29,2021Ordered a day 2 lateral flow test 3 weeks ago. It never arrived and was never dispatched. I called multiple times, they now have an automated message saying they are not answering phone calls. I’ve emailed multiple times and never received a response. Took my money and ran.

Nov 29,2021DO NOT WASTE YOUR TIME OR MONEY! I ordered a 2 day LFT 4 weeks before I travelled, nothing arrived after 2 weeks so I chased rainbow labs to be told the item had been lost in the post and they would send another. a few days before I travelled I still had no test kit so I chased them again and they told me the second kit had also been lost and supplied me with a tracking number which was identical to the first kit. My wife also made a separate order and her kit was also lost. they also provided her with the same tracking number even though it was a different order. We have been back 2 days now and still neither of us have our LFT kits we both ordered and paid for 4 weeks ago. This company should not be on the government recommended list.

Nov 29,2021After the most recent sudden change from lateral flows to PCRs for anyone returning to the UK from abroad, Rainbow have refused to refund already purchased day 2 lateral flows or upgrade them to PCRs. What a pathetic company preying on anyone who needs to travel. Avoid.

Nov 26,2021A perfect experience. Received test next working day and reference for locator form. I followed the instructions in uploading results and received my certificate the same day. Cant fault them. Thanks

Nov 26,2021The service was definitely subpar. I picked up my first test from Earl’s Court without issue. I got a negative result and uploaded the photo. An auto-response email said that the test was successfully received and that I would get a certificate in 0-6 hours but if I did not receive it in 24 hours, to call or email. I did not get the certificate within 26 hours, so I called and received a voicemail indicating that they aren’t accepting phone calls anymore and to instead email, which I did. After not hearing back from my email, I decided to upload the test again. Within a few more hours I finally had my certificate. Hard to say if it was the result of my email or my second upload. I purchased another test to exit the country and had it shipped to my hotel. I ordered before noon as indicated but it did not ship in a timely manner. It ended up taking more than 48-hours to reach me, not 24. After 24 hours I was worried it would not come on time (correct assumption) and since I had issues getting my certificate the first time, I decided to go Earl’s Court to pick up a test so that I would have ample time for my certificate. This time the certificate only took a few hours to come in, so I was able to exit the country without hassle. The whole experience caused unnecessary anxiety.

Nov 25,2021I’ve used this company twice now, both times for a day 2 antigen test collected from the hotel at Earl’s Court. Received code promptly to put on my Passenger Locator Form. Got results certificate back in a few hours. No complaints from me

Nov 25,2021I have to agree with all of the bad reviews. I tried to upload my test on the website. It would NOT recognise my valid address. I called but they do not answer calls. I e-mailed 3 times but nothing. This company says they return e-mails in 24 hours. Nope! They just never respond!!!!!

Nov 24,2021Not available by phonecalls, no answering emails within 24h, doesn’t give result of the test. Have the feeling Scammers site. My wife is waiting for 26 hours for the document (test is showing clearly negative, but no documentation is send)

Nov 23,2021Ordered the Day 2 test for my wife and me on 16th Nov for our arrival on 19th Nov. Still we have not received the Day 2 test kit. Initial response to the email was a royal mail tracking number which for last 3 days has not changed the status saying that "This item is on its way to Royal Mail. The sender has advised they've despatched your item to us." We have lost our money. Calling is not an option, have been writing emails to the support@ email address. Just getting the auto response. Government should remove them from the list immediately.

Nov 23,2021I took a day two test with this company, and despite the photo showing two very clear lines, they issued me with a negative certificate. I had complained and asked they issued the correct certificate, and have heard nothing. I seriously question the competence of this organisation, and have since contacted the UK Health Security Agency having having flagged to UKAS who are now monitoring this organisation.

Nov 23,2021I ordered and paid for a day 2 antigen covid test. I haven't received the test, no response to my email and no refund. Truly appaling service, not only to have to pay for those tests that we can get for free from the NHS but to know those private labs are taking advantage of the situation by ripping us off. The NHS would deserve this money far more than those. I have now submitted a complaint to Gov.uk and hopefully something will be done to get rid of all those useless private labs.

Nov 21,2021Scam do not use Over 20 days since ordered and paid for a 2 day Anti gen test no response on calls automated messages to mail and not a response other than an automated mail saying they will respond usually within 24 hours I have requested a refund and guess what no response This company has no scruples and is in my opinion nothing more than an entity to obtain money by deception Trust pilot should remove them as should the Government from their list of accredited Labs
Hannah Jones
Nov 21,2021Rubbish, no active phone line. Haven’t yet responded to my email after 4 days to answer a simple question, as a result we have had to spend money & purchase another test. Considering this is a government approved service it’s embarrassing

Nov 20,2021Bad. I ordered a PCR test and paid £75, they sent me an Antigen test instead which really screwed with my plans.

Nov 20,2021Day 2 test arrived on Day 4 which was too late. Rainbow Labs did in all fairness respond to my email, but as soon as I asked for a refund they conveniently stopped responding. Phone line goes unanswered too. Ref: RNBLB1061719

Dec 03,2021Ordered tests, didn't arrive. I chased and was promised delivery. The tracking still says Royal Mail is waiting delivery from supplier. No response from company. Resorting to a chargeback. AVOID
