What is a car insurance 'add-on'?

Even comprehensive car insurance doesn't cover you for every eventually. 

Car insurers offer additional elements of cover, which are optional. If you want to add them to your policy, you'll have to pay extra on your premium.


Types of car insurance add-on

Enhanced courtesy car cover

A courtesy car will usually be offered during a claim while your vehicle is in the garage for repairs. 

However, there can be differences between insurers as to whether the availability of the replacement car is guaranteed and whether it will resemble your own (in terms of size and make), or whether you would get one for a period of time if your car was a total loss or stolen.  

Where the bare minimum is on hand as standard, you may have the option of enhancing your replacement car cover for an extra premium.

Legal expenses insurance

Commonly sold alongside car and home insurance policies, legal expenses insurance (LEI) covers the cost of pursuing legal action.

With a car policy, for instance, this might come in handy when trying to reclaim excesses from another driver's insurer - though LEI can be used in various situations. 

Cover levels vary between £50,000 and £100,000 (usually for around £30) - though you can't draw on it automatically. The insurer must be satisfied that you have a 'reasonable' prospect of winning your case.

Breakdown cover

Breakdown cover is often sold as add-on with car insurance - often with different levels of cover available. For instance, some policies provide roadside assistance while driving in Europe .

Personal accident cover

Basic personal accident cover is included as standard in most policies. However, you can pay around £20 to increase the benefit to £100,000. This can also be bought separately. 

Key cover

Key insurance helps pay for a replacement if your keys go missing. The cover provided will also pay for replacement locks. Some providers will also offer 24-hour assistance.

What car insurance fees do I pay?

Set-up fees and renewal fees 

Set-up and renewal fees are relatively rare and are usually charged by online brokers. For example, Hastings Direct charges £20 for new customers and to renew the policies of existing ones.

Adjustment fees

Having to change your policy is likely to cost you. Amendments can range from changing the name on your policy (if you get married, for instance) to adding a second driver. The fee could be as high as £35 and this is on top of any increase in premiums caused by the changes.

Cancellation and ‘cooling-off’ cancellation fees

If you decide you no longer want your policy, even within the 14-day cooling-off period, your insurer may charge you a fee.

Under the law the fee has to be ‘reasonable’ but can still vary greatly from provider to provider. IGO4, for example, charges £75 if you can cancel at any point, but Age UK lets you cancel for free

Pay monthly APR

Paying monthly for your car insurance may seem like a good way to spread the cost, but it can prove expensive.

Paying monthly means taking out a high interest loan from your provider – sometimes with APRs as high as 40%.
