If your tiling work leads to structural damage due to a mistake in your workmanship, it is unlikely to be covered. Public Liability excludes damage to the specific property you’re working on. Contract Works cover may help protect materials and damage from certain causes during the project, but not defective workmanship.

If the tiles are part of the project you’re working on, Public Liability won’t cover accidental damage to those tiles, as they form part of the property being worked on. To protect materials you’re responsible for, you would need Contract Works cover.
