They emailed me saying the sample sent did not have enough blood and that I can buy another test kit for £15 to retake the sample. They didn't tell me how to do this so I emailed customer support. T... See more

Ordered the PCR testing kit whilst abroad expecting it to be there for our arrival home, nope, 24 hours late equating to one unnecessary day isolating! Posted and tracked back next day. 3 days later s... See more

Shocking - DO NOT USE. Rainbow Labs is a sham taking advantage of desperate travellers. 0 stars. They operate out of an unlit, disorganised room in an Ibis Hotel. The person at the desk was not w... See more

I am still waiting for my test…
I am still waiting for my test results,my fault I didn't activate it when I sent the test back but been told to activate it and still nothing. I have a Pre Assessment at the hospital Tuesday as having a operation soon.
This site was in the Government website when I was in Spain visiting my son.Why do they recommend a testing agent that told give any information. I came back Wednesday and still nothing. So upsetting .
Absolutely reliable and great customer…
Absolutely reliable and great customer service.
Be warned
Be warned. Still waiting for the result of my PCR test that was tracked and arrived at their lab on 3rd December. It is now 17th December and still not heard anything despite numerous email requests for results and latterly a refund request.
What a scam
What a scam. Paid for a day 2 test - it never arrived. Was provided with a tracking number and they insisted it had been posted. Checked the tracking number and it showed it was stuck at the depot. When I followed up later - they this time said I had provided an incomplete address and would reship it. This was two weeks after I had returned from my trip and so reshipping the test was useless. I am still, nearly a month after my order - trying to get my money back. AVOID.
Rip off, do NOT use
I sent in my test after taking it and since I forgot to write down the barcode on my testtube before sending it in, the test was void and I wasted £50. Customer service phone number doesn’t work and e-mail was very unhelpful. Do not use rainbow labs, they just try to rip you off.
I ordered 2 tests
I ordered 2 tests, 2 day lateral flow, service ok results within a few hours. 2nd a Pcr to do within 2 days of flying back to the uk, results within a few days. Here I am a week tomorrow, no result. I admit I did not read the the email so although I had posted the test back I hadn’t filled in the notification form. I did it straight away but still no communication or result from them. They do not answer the phone. I am supposed to isolate until I get the result. This close to Xmas I am not happy, so much to do. How do you get through to these people?
Scammers. Do not use them.
Absolute garbage outfit. Obviously a one man band who's set up a harley street PO box and not been able to process the tests as they come through, so probably farming them out to a third party lab.
Awful service - take your money then ignore you
Awful service. Spent £36 for 2x basic tests (they were just LFT’s”) for our return home from the Maldives. Received nothing in the post so we used our own LFTs and did a PCR so we knew we were negative. I have sent numerous emails but been ignored every time. Do not use this company they steal your money.
Fraudulent unreliable company
Fraudulent company
Paid money for 2 lateral flows which never arrived
Phone number is not is used , emails not responded to
Do not use this company . Lost our money sadly
Used Randex … no problems with them
Radio silent
I sent my PCR test to Rainbowlabs on Monday. Royal Mail track and trace confirmed it was delivered to them on Tuesday, a day later. One week later and a couple of emails I am still waiting on the result or any kind of feedback. Trying to call is useless as the phone number only states that it will only reply to an email in 24 hours. I can confirm that this 24-hour turnover is inaccurate. I wonder if I get a refund...
Failure of rapid antigen test to arrive on time
We ordered the rapid antigen test to be taken within two days of return from travel. The order was placed two weeks before it was needed. It had not been delivered when we arrived home and was dispatched two days after our return but only after complaining! This was now too late to use.
A refund was expected at least but after exchanging several emails I just gave up.
Appalling service. A company not recommended.
Wish I'd read some of these ratings…
Wish I'd read some of these ratings before I committed to use them!! Ordered 2 and fair enough 1 came through in good time, but the other we're still waiting for!! Of course you can't call them because they're too busy - what sort of an excuse is that - and all 3 emails I sent have been ignored. Total waste of money and no refund possible....one for Watchdog. I used the Which recommendation as the reason I chose them, so I will be contacting them too.
Worse than useless!
I sent my COVID test to their lab as requested. Royal Mail track and trace confirmed it was delivered to them a day later. It is now seven days since they had my test and I’m still waiting to know the result. They won’t answer their phones so emails are the only way to communicate.
Unhappy with this company, a broken promise!
Their product, a pcr test was promised within two days of order for my day 2 test. My test kit did NOT arrive for twelve days from order and six days past my day 2 testing. I had to scramble to find alternative testing during the day of my day 2 test as required by the UK government. This was not what I expected and will write the company to demand a refund of my purchase. Very disappointing when travelling abroad from the US !!!
Terrible company
Terrible company. Do not use. I ordered a day 2 LF and was sent the test but never emailed the code needed for my passenger locator form. They won’t take phone calls and didn’t reply in time for me to use the test so I asked for a refund. Have sent multiple emails asking for a refund and they never get back to me. Avoid at all costs!
No certificate on Fit to Fly PCR Test
I ordered Fit to Fly PCR test, tests arrived safely and promptly... BUT ... the labs delayed the results causing me to miss my flight costing £900 as I had no PCR certificate. I still have no way of obtaining the certificate after sending 7 emails to support. DO NOT USE THIS COMPANY!
Shocking
Shocking. No lateral test results as stated, no way to contact them. Not bothering to answer the phone. Do not use them.
Ordered a test that never arrived
Ordered a test that never arrived. No proper tracking. Can't get in touch with them. Will now miss my flight.
Completely useless
Completely useless. I ordered a Day 2 test almost a week before travelling abroad. They sent a confirmation email with a reference number and took payment from my debit card. But no test arrived. I flew out assuming it would arrive during my two weeks away. Nothing received in that time. Luckily I had already ordered a test from another company who did deliver on time. I sent an email asking why nothing was received. No response other than an automated reply saying they should reply in 24 hours. A company to avoid in future.
