You can reduce payments by offering a voluntary excess, but keep in mind not to offer a huge sum as you will need to meet it if you make a claim that is your fault. many think they will never make a mistake and it will only be someone else, but statistics shows otherwise.
You should be aware that if you only have third party insurance you are not covered if your car is stolen or if you have an acciden that is your fault. Some car insurance companies do not offer third party only options.
Voluntary excess is an agreement you make with the policy provider to pay a higher percentage of excess at the time of an insurance claim. This also means it would be unlikely you would make a claim for a small amount of cash and risk losing your no claims bonus.
