How to save on your car insurance 

Be experienced

Experienced drivers and have a good driving record can still get a good deal on their insurance. If you are not an experienced driver you can cut car insurance costs by adding a named driver who is older and more experienced to the policy. 

Taking a Pass Plus course if you are a new driver may also reduce your premiums but you will need to check with the insurer first.

The type of car you drive

Having a car with is the type of car you drive, with the car’s speed, security features, and value all playing a big part in increasing the cost of your insurance.

Increase your voluntary excess 

This will result in a cheaper monthly premium. Before you take out car insurance make sure you can afford any voluntary excess. This excess is in addition to the compulsory excess set by your insurance provider. This is what you would have to pay if you ever have to claim. 

Pay upfront 

Pay for your insurance in one go if you can. Spreading the cost of your car insurance over 12 monthly payments may seem cheaper but remember you will be paying interest on top of the amount you pay towards your car insurance premium.    

Drive less

Limiting your miles makes you less of an insurance risk. Simply because you are reducing your risk of having an accident. When you take out your car insurance policy the insurer always asks for an estimate of your maximum annual mileage. You need to try and you’re your mileage low, although you need to be realistic as to how much you will drive. 

Extra security

Having an alarm or immobiliser is considered a theft deterrent and by deterring car thieves you can reduce your car insurance. Not all insurers will offer this, so check first.

Consider black box or telematics insurance 

Black box, or telematics, insurance can help reduce your car insurance over a period of time. 

A small device, the black box is installed in your car. 

Reduce the cost of car insurance when you don’t own a car

You don’t need to own car to get car insurance. Unlike a full car insurance policy, you won’t build up a no claims bonus, but it does mean you can drive someone else’s car, as long as you have their permission. If you are only planning on borrowing a car you can also compare quotes for short-term or temporary car insurance

If you need to insure several cars search multi-car insurance policies.
