Many reviewers say Mustard’s website is quick to navigate and helps them find lower car insurance premiums. Several customers mention clear savings at annual renewal. A large group reports unsolicited calls and says their contact details were shared after they requested quotes. A smaller group says the quotes were unusually high or that policy details were recorded incorrectly during the process.
Examples from available reviews (Dec 2021 – Feb 2026).
Reviewer says Mustard is the best way to find the right policy.
“Best way to find the right one”
Reviewer saved nearly £1,000 on their annual premium.
“Mustard have just saved me nearly £1000 from my annual premium for car insurance. Thoroughly recommended.”
Reviewer received an immediate cold call and fears more spam/scam calls.
“Cold call within second from Mustard associate”
Reviewer says their data was shared and they received scam calls.
“Data sent immediately to scammers - totally cowboy operation.”
Several reviewers describe a smooth purchase process with helpful agent support. Others report poor handling, unanswered calls, and agents they considered incompetent. Service experiences appear uneven from one customer to the next.
Many customers report noticeable premium cuts and comparisons that saved them hundreds. Another group says quotes came in far higher than on other comparison sites and calls the pricing a rip-off. Overall, value results vary sharply by user.
Many reviews point to a site that’s easy to navigate, with a fast quote journey and clear choices. People across age groups, including users over 80, describe it as quick and straightforward. Usability complaints are rare in the sample.
Several reviews claim policy details were recorded incorrectly, including changes to licence information and vehicle-use details. Multiple reviewers say their personal data was passed to third parties, leading to scam or nuisance calls. These complaints focus on data accuracy and handling, not policy features.
Unsolicited calls right after requesting a quote come up repeatedly. Some users say their details were shared even after opting out, and that emails continued after they asked to be removed. Most communication complaints point to consent and third-party contact.
Reviews split between customers who saved money and found the site easy, and those who report data-sharing, nuisance calls, or very high quotes. The dataset includes both strong praise and severe complaints, showing very different outcomes. What users experience seems to depend heavily on how their enquiry is handled.

When I went to acquire an insurance estimate for my auto motorbike from Mustard .co.uk, I made the fatal error of recalling my previous experience, and it was much worse this month.
Some of these corporations may be insurance brokers or other similar businesses, but it seems that scammers are also part of the same network of enterprises that sell your information.
There will be communication despite the fact that you ticked the box stating that you do not want any. This communication will not come from Mustard directly.
An insurance agency requested information that was unnecessary and more related to a financial inquiry than an auto insurance request.
As a result, I've been getting a lot of robocall scams and nuisance phone calls lately.
Try to stay away from it as much as possible!
