Third Party Only is consistently the cheapest car insurance type, often costing 20-30% less than comprehensive policies. This is because it provides only the minimum legal cover required to drive: liability for injuries you cause to others and damage to their property or vehicle. It offers no protection for your own car.
The cost difference is significant. Industry data from market comparisons shows that for a standard driver, a Third Party Only policy can average between $500 to $800 annually, whereas a Comprehensive policy for the same driver might range from $700 to $1,200. The exact saving depends heavily on your driver profile, vehicle, and location.
| Insurance Type | Typical Annual Cost Range (Standard Driver) | Covers Damage to Others | Covers Your Vehicle Damage | Covers Theft/Fire |
|---|---|---|---|---|
| Third Party Only | $500 - $800 | Yes | No | No |
| Third Party, Fire & Theft | $600 - $950 | Yes | No | Yes |
| Comprehensive | $700 - $1,200 | Yes | Yes | Yes |
This insurance is legally sufficient but financially risky. It's a calculated choice to self-insure your own vehicle. If you cause an accident, their repairs are covered, but you must pay entirely out-of-pocket to fix or replace your own car.
It's most suitable for drivers of very low-value vehicles, where the annual comprehensive premium might approach or exceed the car's market value. For instance, insuring a car worth $2,000 with a $1,000 comprehensive policy is uneconomical. It can also be a temporary, low-cost solution for experienced drivers with a strong no-claims history who are purchasing a new car soon.
The major limitation is the lack of coverage for your assets. A single at-fault accident could mean losing your primary transportation without financial recourse. It also does not cover windscreen repair, personal accident benefits, or emergency repairs.
While cheapest upfront, it's not always the most cost-effective long-term. Some insurers offer substantial discounts for comprehensive policies that include security features or safe driving monitoring, which can sometimes narrow the price gap. Always get personalized quotes comparing all three levels of cover.

As a new driver in my 20s, I was shocked by quotes. My advisor said Third Party Only was my cheapest ticket to legal driving. I drive a beat-up old hatchback, so it made sense. I’m covered if I hit someone else’s fancy car, which is my biggest fear. But I know if I mess up and crash into a wall, I’m walking home. It’s a budget choice that lets me build my no-claims discount for the future when I get a better car. For now, it keeps me on the road affordably.

After decades of driving, I’ve owned cars across the value spectrum. My current vehicle is a classic, low-mileage sedan from the early 2000s. Its market value is modest, but it’s mechanically sound. I opted for Third Party Only cover after running the numbers. The comprehensive premium was nearly 40% of the car’s total worth. That’s poor value. My risk is manageable—I drive infrequently and have a perfect record. This meets the legal requirement and protects others, which is the core purpose of insurance. I set aside the premium difference into a savings account for potential self-repairs. For a low-value car and a low-risk driver, it’s the most rational financial decision.

I drive for a living, using my personal car for rideshare platforms. My needs are specific. While the platform provides commercial cover when I have a passenger, I need a base policy for when I’m logged off or driving personally. Third Party Only is the baseline minimum I can legally have. It’s the cheapest option and fulfills that basic requirement. However, it’s a vulnerable position. If I’m at fault in an accident during a personal errand, my work tool is out of commission with no insurance help. Many professional drivers in my network use this as a stopgap, but we all acknowledge the financial risk. It prioritizes low cost over business continuity.

Choosing for our family’s second car, an older model used for short trips, led us to Third Party Only. The comprehensive quotes felt like paying for coverage the car’s value didn’t justify. We treat it as a calculated component of our overall financial plan. The significant savings on this policy are redirected into our emergency fund, which acts as our self-insurance pool for that vehicle. We would never choose this for our primary, newer family car. The decision was purely economic, based on the asset’s depreciated value. It works because we can absorb the potential loss of that secondary vehicle without it crippling our finances or mobility. It’s not the right choice for every car or situation, but for a low-use, low-value asset, the math is clear.
