AT A GLANCE

How the protection works

The proposal should match the work performed, project values, people, tools, plant, locations, heights, depths, hot work and contractual obligations.

Plumber Insurance is not one universal contract. Eligibility, sections, limits and wording vary by insurer and must be matched to the individual risk.

CONTRACTING RISK

What may be covered

  • Public and employers’ liability for insured activities and declared employees or labour.
  • Tools, plant, hired-in equipment, contract works and materials where selected.
  • Professional, environmental, motor or business interruption protection when separately required.

Cover applies only as stated in the quotation, schedule and full policy wording.

BOUNDARIES

Common exclusions and limitations

  • Work, trades, locations or techniques outside the accepted business description.
  • Defective workmanship itself, professional design or pollution unless specifically covered.
  • Unattended tools, inadequate security and contractual liabilities beyond the policy wording.

This is not a complete list. The actual wording, endorsements, excesses and schedule determine the protection.

CLAIMS IN PRACTICE

How a claim might arise

01. Work at a client site accidentally damages existing property.

02. An employee or member of the public alleges injury connected with the work.

03. Tools, plant or contract materials are stolen or damaged during an insured project.

These examples are illustrative only and do not confirm that a particular claim would be covered.

CHOOSING COVER

Questions worth resolving

  • Does the proposal describe every plumbing and heating activity, including domestic, commercial, industrial, gas, hot work or work at height where applicable?
  • Are turnover, largest contract values, employees, subcontractors, tools, plant and territorial exposure accurately stated?
  • Are escape-of-water exposure, hot work, hazardous sites, previous claims and customer contract requirements clearly identified?

For a wider checklist, see the DIBNI Commercial Insurance Proposal Guide.

CONNECTED RISKS

Related protection to consider

  • Property and business interruption where physical damage could stop operations.
  • Public, employers’ or product liability for injury and property-damage exposures.
  • Cyber, professional indemnity or management liability where data, advice or governance creates additional risk.
  • Motor, marine, travel or other specialist protection where the activity requires it.

QUESTIONS

Frequently asked questions

Does the description include every trade and hazardous activity?

The answer depends on the facts presented to the insurer and the terms offered. Accurate, current information is essential.

Are contract values, plant, tools and liability limits sufficient?

Limits and conditions should be tested against realistic loss scenarios, contracts and the time or cost of recovery.

What insurance and indemnity requirements appear in customer contracts?

Documented controls help an insurance professional explain the risk and may affect available terms.
