Insurance for Domestic and Small Commercial Plumbing

Plumbing domestic and small commercial insurance is for plumbers whose work is mainly in homes, flats, rental properties, shops, offices, salons, surgeries, cafes and similar lower-complexity premises.

The policy should reflect the actual work carried out, including repairs, maintenance, installation, bathroom plumbing, pipework, tap and valve replacement, leak response, drainage-related work and any heating or gas-adjacent activities.

Insurer Questions

  • What percentage of work is domestic, landlord or small commercial?
  • Do you carry out installation, repairs, maintenance, call-outs or bathroom plumbing?
  • Do you undertake gas, heating, hot works, drainage or larger site work?
  • What tools, materials, parts and customer equipment are involved?
  • Do you use employees, subcontractors or work under agency or landlord contracts?

Escape of Water and Finished Premises

Homes and small commercial premises often contain finished floors, stock, furniture, technology and customer belongings. The policy should be reviewed around escape of water, accidental damage and completed-operations wording.

When Cover Needs to Broaden

If the business takes on larger commercial projects, major construction-site work, industrial plumbing, gas work, heating installation or design responsibility, the activity description and insurer questions may need to broaden.
