The cheapest policy is always the best.

This is not necessarily the case. It always depends on your individual needs so be sure to shop around and seek out the best value to suit your requirements. 

While there are many options available, in a general sense, there are two types of policy to choose from when insuring your private car - comprehensive and third-party, fire and theft. A comprehensive policy will carry a higher cost but in return you receive a higher level of cover.

If you have an accident, your comprehensive insurance policy will pay for the cost of repairs to your car and cover any other damage to another vehicle or injury to third parties. You’re also covered against loss of or damage to your car through fire or theft, loss of personal belongings and often windscreen damage. 

Third Party, Fire & Theft covers damage you cause to another vehicle and or injury to third parties. It also covers loss of or damage to your car through fire or theft.  The difference between this and comprehensive cover is that third party, fire & theft doesn't cover your own vehicle if it's damaged in an accident.
