Third Party Property Damage (TPPD) Insurance.
What it might cover: this is the most basic optional car insurance. It usually covers the cost of damage your car causes to other people's property (e.g., their car, fence, house) if you're at fault in an accident.
What it might not cover: it generally does not cover any damage to your own car, regardless of who is at fault. It also doesn't generally cover personal injuries (that's what CTP is for). It's can be the cheapest optional cover.
Third Party Property, Fire & Theft (TPFT) Insurance.
What it might cover: this type of policy usually includes everything covered by Third Party Property Damage, plus it can provide cover for loss or damage to your own car if it is stolen or damaged by fire.
What it might not cover: it generally doesn't cover accidental damage to your own car from collisions (unless it's fire or theft related) if you're at fault.
Comprehensive Car Insurance.
What it might cover: this is usually the highest level of car insurance and offers the broadest protection. It could cover:
Damage to other people's property (like TPPD).
Loss or damage to your own car due to a wide range of events, including accidents (regardless of fault), theft, fire, malicious damage, storms, hail, floods, and vandalism.
It can include optional extras suchas excess free windscreen cover or hire car cover.
Key features: You often have the choice between agreed value and market value for your car's payout in the event of a total loss. This could be the most expensive type of car insurance but usually offers the most comprehensive coverage.
