How do I know my details are secure?

How will you respond to my emails?

We won't keep you hanging around for a response. Our friendly and efficient Diamond experts aim to reply within 24 hrs.

What is a No Claims Bonus?

Every year you drive without making a claim or having a claim upheld against you, earns you an additional year of NCB, which can lead to discounts off your renewal premium. Your No Claims Bonus builds up to a maximum of 15 years.

Can you explain what an excess is?

If you make a claim you must pay an excess, regardless of who is to blame.

If you have Comprehensive cover, the total accidental damage excess is calculated by adding together the relevant compulsory and voluntary excesses.

A compulsory excess automatically applies to your policy. This depends on the car that is covered, the age and experience of the drivers on your policy and whether you have protected or guaranteed No Claims Bonus.

A voluntary excess is the excess you agreed to pay at the start of the policy.

Details of all your policy excesses can be found on your Policy Schedule.

Which parts of 'Your Car Insurance Guide' applies to me?

If you have Comprehensive cover all sections of the Guide apply.

If you have Third Party, Fire & Theft cover only, the sections of the Guide that apply to you are 2, 3, 5 and 6.

If you have Third Party cover only, the sections of the Guide that apply to you are 3, 5 and 6.

However, there are Conditions & Exceptions that apply to individual sections of the policy and General Conditions and General Exceptions that apply to the entire policy.

How do I make a claim?

If you need to make a claim or report any incident, just call our Claims Team on 0844 543 4420, they'll be happy to help. Alternatively you can call 62662 from your mobile at a fixed rate of 15p per minute. Remember - it's important to report all accidents within 48 hours of the incident, even if you are not claiming.

Calls to 0844 numbers will be charged at 5p per minute from BT Landlines. Calls from mobiles and other networks may vary.

What if my car or circumstances change?

Your Diamond Policy Booklet gives you all the information you need to know about how to keep your policy up-to-date and what to do if you need to change your details.

It's important to remember that failing to tell us about a change to your personal details could invalidate your policy. If you need to make a change - or are uncertain if you should tell us about a change - please don't hesitate to call our Customer Care Team on 0871 882 2200 (calls to 0871 numbers are charged at 8p per minute plus network extras) or on 62661 from your mobile at a fixed rate of 15p per minute.

What happens to my No Claims Bonus (NCB) if I make a claim?

You can find full details of how your No Claims Bonus entitlement will be affected in your Policy Booklet.

Am I insured to drive someone else's car?

To see whether or not you are entitled to this cover, please refer to Section 5 and 6 of your current Certificate of Motor Insurance. Alternatively, if you call our Customer Care Team on 0871 882 2200 (calls to 0871 numbers are charged at 8p per minute plus network extras) or on 62661 from your mobile (at a fixed rate of 15p per minute), they will be happy to explain to you the terms of your cover.

Am I covered if someone else drives my car?

Only drivers named on your current Certificate of Motor Insurance are covered by Diamond. If you would like to add a driver to your policy please call our Customer Care Team on 0871 882 2200 (calls to 0871 numbers are charged at 8p per minute plus network extras) or on 62661 from your mobile (at a fixed rate of 15p per minute). There may be an additional charge for making this change to your policy. Just make sure you have the following details ready when you call, and one of our Customer Care Team will be happy to assess if we can add the driver.

  • The driver's name, date of birth and occupation
  • The number of years the named driver has held their licence
  • Details of any claims the named driver has had in the last 3 years
  • Details of any convictions the named driver has had in the last 5 years

Am I insured to travel abroad?

Your policy gives you the cover described in your current Certificate of Motor Insurance for events occurring in:

  • Great Britain, Northern Ireland, the Isle of Man and Channel islands
  • Any other country which is a member of the European Union
  • Norway, Switzerland, Iceland, Croatia, Andorra and Liechtenstein

The car is covered whilst it is being transported by air, sea or rail between those countries.

Your policy automatically includes an International Motor Insurance Certificate (on your current Certificate of Motor Insurance) for a maximum of 30 consecutive days in any one trip up to a maximum of 90 days in a year.

The International Motor Insurance Certificate is only valid for the above named countries and there is no need to call us if you are taking your car to any of these countries but you do need to take your Certificate of Motor Insurance. However, should you wish to travel to any country not included in the above list please call us and we may, in some instances, be able to issue a Green Card for you.

Customer services number: 0871 882 2200 (calls to 0871 numbers are charged at 8p per minute plus network extras.
