TransUnion UK Reviews 

Great service, fast response, couldn’t fault it.

TransUnion still haven't updated my address. I have been registered on the electoral roll for over a year at my new address but according to them I'm not. Because of their incompetence it has dropped my credit score by over 200 points since I moved. Despite contacting them on numerous occasions and speaking to my bank and local council on multiple occasions, and them all stating I do in fact live at my current address, TransUnion are STILL not updating my address. Please avoid at all costs if you, like me are trying to secure funding for a business. You won't get any type of loan because of their incompetence.

I wrote to TransUnion with a complaint about my credit score and the incorrect information contained in it. They wrote back a 'copy & paste' reply which did not consider or investigate my specific concern.

Pulane was brilliant, gave me an understanding of why I may have been declined credit, however they cant go into specifics through the phone which is fine, so currently on the website to gather an understanding of why and hope the issue gets resolved, thank you.

My experience with TransUnion has been nothing short of appalling. They held an incorrect version of my name on the electoral register, and despite providing official council documentation, they repeatedly failed to correct it. Even worse, they invented multiple variations of my name, none of which matched my legal identity.

Their system then distributed these incorrect names to third‑party companies, including insurers and identity‑checking organisations. I discovered this only after obtaining a hard‑copy credit file, which showed that companies such as Aviva and LexisNexis had run searches using the wrong name supplied by TransUnion. This is a serious failure in data accuracy and quality control.

I raised disputes multiple times, and TransUnion repeatedly marked them as “successful” even though nothing had been corrected. Their responses were inconsistent, contradictory, and showed no evidence of proper investigation. I eventually had to file a formal GDPR complaint and send it by recorded delivery because the standard dispute process was completely ineffective.

The amount of time, stress, and unnecessary cost caused by their mistakes is unacceptable. A credit reference agency should be able to handle something as basic as a person’s name, yet TransUnion failed at every stage — storing it incorrectly, sharing it incorrectly, and failing to fix it when notified.

Based on my experience, TransUnion’s data handling and dispute resolution processes are unreliable and deeply flawed. I would strongly advise anyone to check their TransUnion file carefully, because errors are not only possible — they can spread to multiple organisations without your knowledge.

An awful and unlawful company. Unhelpful consumer services. Ongoing dispute that isn’t getting resolved. Credit file containing false information that is significantly impacting my finances and no representative willing to help.

TransUnion lowers credit scores, and I have the impression that this is working against borrowers, encouraging them to take out loans with higher interest rates. If you want to contact them, they make it difficult. For example, when you enter your postcode address in their contact app, they claim it's incorrect, which means you can't contact them.

The staff were very kind an helpful to my problems,
They did what was physically possible and it would be corrected as soon as posible.
So that i can apply for a Credit card without any problems.
As after 6 years the mark was not deleted as t should have been it is now nearly 9 years after my insolvency
and becaouse of the fed mark i was being refused a Credit crad..

Thanks a lot to TransUnion and all th staff who have helped me.

THANKS VERY MUCH.

Hats off to them for being so kind helpful and professional.

very good service response i was given was very positive

Nice service ! No complain until now ; )

TransUnion held incorrect personal data on me and told me it would take 28 days before they could tell me which data source had the incorrect data, in clear breach of UK data protection law. It was their competitor, Experian, who actually had the correct data who found the source, which allowed me to go direct and fix the issue myself. Then this joke of a company, TransUnion, had the audacity to claim that they had the correct data all along when I know and can prove thet had the wtong date of birth. Breaching data protection law, poor service and bad attitude.

By way of update, I emailed TransUnion as requested on 12 March. On 30 March, they replied, once again denying that there was a problem. If I could lower my reveiw score, I would. Don't waste your time with this company.

My credit rating went down recently, which surprised me as the only item that changed was paying off a loan and remortgaging from one provider to another. Surely the fact that a provider was positive enough to offer a new mortgage deal should be a positive?

TransUnion sent a response which read as an off-the-shelf everything in there list, rather than a specific reason why my rating had gone down.

Almost impossible to contact them. Their app does not work.
Took 5 months for them to reply to an email the “sent to the wrong team”.

Poor Company , have had to send them through two disputes in a short period of time to keep advise that I am on the electoral register. Not good enough .

I am very annoyed you have allowed a Hard Search on my credit file,

I have not applied for any credit and the postcode you have used is not mine.

Your website is a joke ,it’s says raise dispute but nowhere to actually do and you just go round in circles

I will be seeking a final response from you so I may take my complaint to The Financial Ombudsman.

Karabo was really helpful

Nice and very helpful

Just not helpful

Simple and good service

‼️ I am adding it that my actual experience with TransUnion has been absolutely diabolical and I have written another review on this! This positive review is for Terry and Terry only! TransUnion are an awful company who most of the time have no idea what they are doing‼️

I am writing this 5 star review for one reason and that is to thank Tery who I spoke to today (24.2.26) she was the only person to help me (out of 6 other people). Months I had been trying to sort an issue out that tery has hopefully sorted in minutes! Thankyou Tery!
She seems to be one of the only competent staff members TransUnion have….i will be writing another review about my experience in due course….
