What happens if you damage a customer's property?

Cheap mistake, expensive day: when accidental damage has knock-on costs
A drill goes through a pipe you didn't know was there. A tool slips and damages an expensive floor. Something gets knocked onto a worktop and cracks it.
Accidents happen. The damage might stop there. But a relatively small mistake can also have knock-on effects that aren't obvious at first.
There could be other property involved, for example, or extra time and cost involved in putting things right.
And that's before you get into the question of who's responsible.
One accident can lead to another problem
Take the hidden pipe.
The hole itself may be straightforward to repair. But if escaping water reaches flooring, a ceiling or the customer's belongings, the problem may extend beyond the pipe itself.
The same applies elsewhere. Crack a basin and surrounding work may be affected. Damage a floor and individual boards or tiles might not be easy to match.
The first thing that goes wrong isn't always the whole story. What happens as a result can matter just as much.
What if it's someone else's work?
Not everything on a job belongs neatly to you or the customer.
On a larger project, several trades may be working in the same space. An accident could damage something another contractor has already installed. Finished work might also have to be removed or replaced as a result.
That's where responsibility can become less straightforward.
Who owns the damaged property, who did the original work and what happened can all affect who's responsible.
The circumstances can also affect whether insurance cover applies. This depends on the terms, conditions, limits and exclusions of the policy.
It's not always about property
Accidents can involve people as well as property.
A customer could trip over something connected with the work. A falling object could hit someone.
What happened and who's legally responsible can affect whether a business faces costs as a result.
Where public liability insurance comes in
This is where public liability insurance may be relevant.
Public liability insurance may cover a business if its work accidentally causes injury to a third party or damage to their property.
Whether an incident is covered depends on what happened and the individual policy. Terms, conditions, limits and exclusions can all affect whether cover applies.
Accidental damage and faulty work aren't the same thing
There's an important difference between accidentally damaging someone else's property and the cost of correcting faulty work.
Public liability insurance may cover third-party property damage caused by an accident. That doesn't necessarily mean the cost of putting faulty or incorrectly completed work right would also be covered.
For example, accidentally damaging a customer's flooring while carrying out a job is different from having to redo flooring because the original work was completed incorrectly.
The circumstances and individual policy wording determine what is and isn't covered.
Accidents happen. Knowing what was damaged and how it happened can make the difference between a straightforward mishap and something with wider consequences.
