How can you save money on Diamond car insurance?
The first offer an insurer makes isn’t necessarily the best they’re able to provide - especially if you’re renewing. So, before coughing up your cash, check what other insurers are offering for comparable cover and ask if your current insurer can better it.
Carefully consider what’s optionally included in the quote. You may want the confidence of an all-singing, all-dancing policy - but certain add-ons might not be for you, or could duplicate cover you already have separately.
Where you buy your cover can sometimes make a difference to what you’ll end up paying, which is why we recommend checking prices through multiple comparison sites (where available) as well as trying them direct.
