Componentauthority Reviews 

I ordered and received my part within a couple of days.
I found the website easy to use, the price was good and included free delivery.
All along, I was kept informed about the process and it duly arrived very quickly, well - packaged and labelled.

Part ordered and arrived in a few days. Excellent packaged and labelled. Part was a straight swap and easy to fit. Very easy to negotiate the website and would highly recommend.

Ordered an item and thought everything was sorted.
When i received no dispatch.email, i contacted them.
They came back and said I lived on a remote part of the country and would not be delivering the item. They asked me to provide them with an alternative address. Absolute shambles of a company

Do not order from here.

Delivery is very slow (and with EVRI). And then when the order (over £100 worth of parts) finally arrived, it wasn’t complete.

Don’t waste your time or money. Go elsewhere.

They advertised 3day delivery, acknowledged order and said they would inform when shipped so when no notification arrived I queried only to be told they had no stock, but if I waited they could supply, or I could cancel the order but no instructions as to how or when I would receive a refund.
Pay Pal issued a full immediate refund when I opened a case
Tread carefully folks price is not everything!

Not a trustworthy company. I bought an EV charger cable from them in August 2023. In June 2024 it blew up whilst charging my car and could have started a big fire. Luckily it didn't. I contacted CA to notify them of the issue and ask for a refund for the faulty product which was still well within the 12 Month warranty period. They tried to pin the blame on me for improper use!?! Despite having no evidence and me using it solely for charging my car.. which is what it's for! After much back and forth they offered to pay a maximum of 30% of an alternative product or to send me a new charger cable (which I've refused as I don't trust their products- oh and they said I'd have to pay for the £30 postage if I wanted them to send it). I rarely write review posts but I would steer clear of this company if you want peace of mind about the products you're buying from them.

I've now had a CCJ put against them. Terrible, unreputable company

Ordered slave battery for stop start Mercedes C Class. Component tracked and arrived on time. Despite not having the Mercedes logo fitted a treat and works Ok now. Extremely pleased.

Do not buy! It's Chinese products that don't even fit, save your money and buy from somewhere else.

This company is atrocious, they have taken my money then changed the agreement, there is only automated responses to enquiries, and no customer service whatsoever, DO NOT BE TEMPTED TO DEAL WITH THESE PEOPLE, NO CONSCIENCE, NO QUALITY, NO ETHICS OR BASIC HUMANITY...SCUM.

It doesn't fit the rf900 1994 I asked for a refund and apparently my options are either to accept a 30% refund or to pay for postage and a 30% restocking fee either way i have lost 3 quarters of my money spent on a part that was advised wrong.not the best way to do business.

Great service great price

Purchased from these then read the horror reviews well what a load of rubbish.

Best price & best service well done to you 🙌

DO NOT ORDER FROM THIS COMPANY ! They sent me a completely incompatible and faulty part and are now refusing to give me a refund, complete and utter crooks!
Horrendous to deal with, AVOD AT ALL COSTS

I did not recieve the item and I'm starting to think this site is a scam. I have tried emailing them and contacting them using there chat system no answer on either, the telephone number looks suspicious. The delivery company says they have not received the item, it was supposed to arrive in 5 days its now been 8 days and its not even been sent to the delivery firm. I have asked for a refund but no answer so I think my next step is issuing a section 75 before its to late and I lose my money. Not good.

We bought a 3-pin EV car charger which worked seemed to work fine for a couple of months (probably 3 or four uses) and then over heated and blew the fuse.
I replaced the fuse and the same thing happened again.
I got in touch with the seller and was told to try a lower grade fuse! Upon researching whether this was a good idea or not it became clear that it absolutely was not!
In the end we received a 25% discount which wasn’t as much as we hoped - however they were quick to respond and didn’t try to duck the issue too much.

I purchased an electric EV charger in December. By the end of January this had not only stopped working, but had severely overheated, melting the plug, and exploding my electric socket outlet. This item is dangerous and could easily have caused a house fire with children in it. The plug has the wrong amp fuse in it and is just a dangerous product that overheats. I rightfully asked for a full refund and was instead told to repair the plug myself, and accept a 20% refund. Conpletely unacceptable and I will fight my refund through my credit card company. Absolute disgusting treatment from an awful company. I urge you to stay safe and do not buy from this company.

I had some issues with the compatability of the spre part ordered for my printer but thid was quickly resolved

Shocking !!! … ordered a set off bulbs and ballasts for my vw ,checked all the part no.s off the original ballast and after only 3 weeks , one side has stopped working . Multiple emails asking for part no.s , vin plate , car reg …. Stay away !!!

order a part for mercedes over £1000.00 was back and fourth with emails for over 3 months becasue the item never arrived. even tho fedex admitted to the loss of the package they would never even file a email to get refunded from fedex as they was the courier purchaser this resulted in me to do a chargeback from my bank got refunded eventaully from my bank but componany auth would do nothing to help. they pose under fake names and pretent the company is based in the UK but they are actually chinese cheap made products. ORDER AT YOUR OWN DEMISE.

The product I received from them stopped working almost immediately. I reached out to let CA know and they refused to exchange it, which was disappointing. They suggested I try fixing it myself, which I found impractical and frustrating. I believe this might be due to logistical challenges, given their base in the States, making it costly for them to provide adequate aftercare to customers in the UK.

Adding to the frustration, attempts to reach them by phone have been unsuccessful. Instead, I received generic emails instructing all communication to be conducted via email, which lacks the personal touch of human interaction and feels more automated than personable.

A6420900142 for an E350 Mercedes
