Property damage liability explained

Reviewed by the Apex broking team · Last reviewed 2026-10-16

Property damage liability is your legal liability to pay compensation when you physically damage, destroy or cause the loss of use of someone else's tangible property. It matters because it is one of the two core triggers, with bodily injury, for public, products and motor liability cover.

Part of: Public liability insurance

In short

In UK liability policies, property damage usually means physical loss of or damage to tangible property belonging to a third party, often extended to loss of use of that property. Public liability covers property damage caused by your business activities, products liability covers damage caused by products you supply, and motor policies must cover damage to property under the Road Traffic Act 1988, with a permitted minimum of £1.2 million per accident. Common gaps include property in your care, custody or control, the cost of redoing your own work, and pure financial loss. Professional indemnity policies often exclude property damage altogether.

What property damage means in a liability policy

Liability policies pay sums you are legally liable to pay as compensation for injury or damage you cause to others. Most UK wordings define property damage along these lines, subject to the policy terms:

Physical loss of or damage to tangible property belonging to a third party, such as a client's flooring, a neighbour's wall or a parked car.
Loss of use of that property, often covered where it follows physical damage, and sometimes where tangible property is obstructed but not damaged. Wordings vary on this point.

Three things usually fall outside the definition. Pure financial loss (a client loses money without any physical damage) is generally a matter for professional indemnity rather than public liability. Electronic data is commonly not treated as tangible property. And damage to your own property is a first-party loss for a property policy, not a liability claim.

Liability also has to exist. The insurer pays where you are legally liable, usually in negligence, nuisance, under statute or (to a limited extent) under contract. A contractual promise to pay for damage regardless of fault may go beyond what the policy covers.

Where property damage sits across policies

Public liability

Public liability insurance covers property damage and bodily injury to third parties arising from your business activities, typically at your premises or while working elsewhere. This is where most trade and contractor property damage claims land, from water leaks to fire spreading from hot works.

Products liability

Products liability covers property damage and injury caused by products you make, supply or repair after they leave your control. Under section 5 of the Consumer Protection Act 1987, the strict liability regime covers property damage only where the property is ordinarily intended for private use and mainly used privately, excludes damage to the product itself, and awards nothing where the property damage is £275 or less. Claims by businesses are usually brought in contract or negligence instead.

Motor

Section 145 of the Road Traffic Act 1988 requires a motor policy to cover liability for damage to property caused by or arising out of use of the vehicle on a road or other public place in Great Britain. Under section 145(4)(b), the policy may cap that property damage cover at £1,200,000 for any one accident (the figure in force since 31 December 2016). The policy need not cover damage to the vehicle itself, goods carried for hire or reward, or property in the insured's custody or control. Many commercial motor and fleet policies offer higher property damage limits, which can matter where a vehicle hits a building or rail infrastructure.

Employers' liability

Employers' liability covers injury to employees, not damage to property, so property damage claims fall to public, products or motor cover.

What it means in practice

These scenarios are illustrative only.

Plumber's leak: a fitting fails and floods a client's kitchen and the flat below. The water damage to the client's and neighbour's property is a classic public liability claim. The cost of replacing the faulty fitting and redoing the work is commonly excluded.
Defective component: a supplied part overheats and damages a customer's machinery. Damage to the machinery may fall under products liability; the cost of the part itself, and of a product recall, usually does not.
Van into a shopfront: a delivery driver mounts the kerb and damages a shop. The motor policy responds to third-party property damage up to its limit, which is usually above the statutory minimum.
Design error: an engineer's design causes a structure to crack. The claim may be for property damage, but it flows from professional advice, which raises the PI question below.

How insurance responds and common exclusions

Issue	Usual position	What to look for
Care, custody or control	Commonly excluded under public liability	Extensions for premises worked on, or customers' goods
Property being worked on	Damage to the part being worked on often excluded	Wording that limits the exclusion to that part only
Faulty workmanship	Cost of rectifying your own work excluded	Cover for resulting damage to other property
Contractual liability	Covered only where liability would exist anyway	Indemnity clauses in contracts
Pure financial loss	Generally outside public liability	Separate PI or financial loss extension

The care, custody or control exclusion trips up many businesses. If you take a client's equipment back to your workshop, store goods for others or work inside occupied premises, damage to that property may fall outside public liability. Extensions are often available, sometimes with a lower sub-limit, and some risks are better placed under goods in trust or contractors' all risks cover.

Check the excess too: property damage claims often carry a higher excess than injury claims, especially for heat or water damage.

Property damage in professional indemnity: the BI/PD exclusion

Many PI policies contain a bodily injury and property damage exclusion, on the basis that those claims belong under public or products liability. The exclusion is commonly drafted with a carve-back, so that property damage arising from a breach of professional duty, such as negligent design or advice, remains covered.

The difference matters. A designer whose drawing leads to a collapse needs the PI policy to respond, because public liability commonly excludes claims arising from professional advice. Read the two policies together so the gap does not open between them. Our guide to consequential loss under PI explains how financial loss following damage is treated.

Property damage vs related concepts

Property damage vs material damage: material damage is a property insurance term for damage to your own assets. Property damage liability is about other people's property.
Property damage vs pure financial loss: if nothing tangible is damaged, the claim is usually financial loss and outside public liability.
Public vs products liability: public liability covers damage from your activities; products liability covers damage caused by products after they leave your control. See PI vs product liability for how they interact.
Motor vs public liability: damage caused by use of a vehicle on a road is a motor risk; damage by plant used as a tool at a site may sit under public liability. Check how your policies split this.

What to check

How the policy defines property damage, and whether loss of use without physical damage is included.
Whether your limit of indemnity suits your work and contracts.
Care, custody or control and property worked on exclusions, and any extensions.
Your motor property damage limit compared with the Road Traffic Act minimum.
For design work, whether the PI exclusion has a professional duty carve-back.

Frequently asked

What counts as property damage in public liability insurance?

Usually physical loss of or damage to tangible property belonging to someone else, often including loss of use of that property. Examples include water damage to a client's home or fire damage to a neighbour's building. Pure financial loss, data and your own property are commonly outside the definition, subject to the policy terms.

What is the minimum property damage cover for UK motor insurance?

Section 145 of the Road Traffic Act 1988 allows a motor policy to limit property damage cover to £1,200,000 for any one accident. That is the legal minimum for property damage. Many commercial motor and fleet policies offer higher limits, which can matter if a vehicle damages buildings or infrastructure.

Does public liability cover damage to property I am working on?

Often only in part. Many public liability policies exclude damage to property in your care, custody or control, or to the specific part you are working on. Extensions are commonly available. The cost of putting right your own faulty work is usually excluded altogether, though resulting damage to other property may be covered.

Does professional indemnity insurance cover property damage?

PI policies commonly exclude bodily injury and property damage, because public and products liability are meant to respond. Many include a carve-back so property damage caused by a breach of professional duty, such as negligent design, is still covered. Check the wording alongside your public liability policy.

Is damage caused by a faulty product covered?

Damage a defective product causes to other property is usually covered by products liability, subject to the policy terms. Damage to the product itself, replacement costs and product recall costs are commonly excluded. Under the Consumer Protection Act 1987, property damage claims of £275 or less cannot be brought.
