Hiring a plumber that holds public liability insurance for their business is critical, as it will protect you from paying hundreds or even thousands in repair costs if anything bad were to happen on the job. This is especially important for bigger jobs such as renovations, as there is always a small chance that something may go wrong and your property may be damaged. With an insured plumber, you can have confidence knowing that they will have the means to pay for any repairs if they are needed.
