FREQUENTLY ASKED QUESTIONS

What is the most important cover for construction businesses?
Public liability is the most essential cover, protecting you if someone is injured
or property is damaged due to your work. Employers’ liability is also legally required
if you have staff or labour-only subcontractors.
+-
Do I need contract works insurance?
Yes, if you are responsible for materials, work in progress or temporary works.
It protects the physical part of the project from damage, theft or unforeseen events.

How do I know what liability limit I need?
Many sites require a minimum of £5M public liability. Domestic work may need £1M–£2M.
For commercial contracts or local authority work, £5M–£10M may be mandatory.

What if I only do small projects?
Even small trades benefit from combined liability and tools cover.
Policies are tailored to the scale of your work so you don’t overpay.

Do I need professional indemnity insurance?
You may need PI if you provide design, drawings or specifications,
even informally. Many contractors now use design-and-build contracts, which involve PI exposure.
