Why get car insurance from Diamond?
Part of the Admiral Group, Diamond Insurance specialises in providing cover for female drivers. While insurance premium calculations can no longer take gender into account (since the introduction of European anti-discrimination legislation in 2012), Diamond differentiates its policies by offering benefits more likely to appeal to women, such as handbag cover and child car seat cover as standard.
Diamond offers both multi-car and single-car policies and has an admirable five-star rating from industry analyst Defaqto, but you’ll have to pay an extra premium to add breakdown cover to your Diamond policy.
Contact Diamond
You can manage your Diamond policy online via the company website, which includes a webchat service.
You can also report a claim online, or by calling 0330 220 2037 between 8am and 6pm Monday to Friday, 9am and 4pm on Saturday or 10am and 4pm on Sunday.
For emergency accident recovery, meanwhile, call 0800 600 840 at any time.
If you like, you can also write to the company at Diamond Insurance, Ty Admiral, David Street, Cardiff, CF10 2AA.

At MoneySuperMarket, we want to give you clear, accurate and trustworthy information so you can make confident financial decisions for your circumstances.
Every page on our website goes through a careful editorial process before it is published. It’s written or reviewed by one of our experienced experts, checked for accuracy, and updated regularly to reflect the latest information.
We do use AI tools to support our research and drafting, but a human editor is always in the loop to review, fact-check and approve everything before it’s published, so you can trust that what you’re reading is both reliable and up to date.

How does MoneySuperMarket make money?
We get paid by the companies we work with, but the payment we get doesn’t have any bearing on the information we provide. We get paid in different ways, depending on the type of product or service you buy through us. Our goal is to search deals from as wide a range of companies as possible, but we only show results from our partner providers.
Our comparison service is, and will always be, free to use.
Why should I use a price comparison website?
One of the best ways to get the lowest prices and best deals is to compare quotes from different companies. We do the work for you, comparing quotes side-by-side and giving you all the information you need so you can choose the right deal for your needs and your wallet.
We don’t give recommendations or financial advice, but we give you clear information so you can choose financial products that suit your circumstances.
Does MoneySuperMarket work with all the providers on the market?
No, not every company can be included in our service. This is because some companies don’t want their products included on comparison sites, and some decide that they would rather not pay a fee. There are also a few smaller providers who can struggle to cope with the volume of customers that can find their products if they appear on MoneySuperMarket.
Our goal is to search deals from as wide a range of companies as possible so that you can choose the deal that suits you.
