Why Use a Metal Fabrication Insurance Checklist?

Metal fabrication businesses face a combination of property, liability, fire, pollution and operational risks that are often underestimated by standard insurance policies. Welding, cutting, grinding, heavy machinery, high-value stock and site-based work all introduce exposures that can leave serious gaps if cover is not structured correctly.

This checklist is designed to help workshop-based and site-based fabricators review their insurance arrangements, identify common omissions, and prepare the right information for insurers. It can be used before a renewal, when changing brokers, or when expanding into new types of work.

1. Business Activities & Disclosure

Clear disclosure is critical. Many claims problems arise because insurers were not given a full picture of how a fabrication business actually operates.


  • Have you fully disclosed welding, cutting, grinding and hot works?
  • Do you work on client sites as well as your own workshop?
  • Are you involved in installation, erection or structural steelwork?
  • Do you carry out any design, specification or advisory work?
  • Are subcontractors used (labour-only or bona fide)?
  • Have turnover split and activity percentages been declared accurately?

2. Public, Products & Third-Party Liability

Liability claims can arise from injuries, property damage, defective fabricated items or fire caused by hot works.


  • Is public liability in place at an appropriate limit (£2m–£10m typical)?
  • Does the policy explicitly accept welding and hot works?
  • Is products liability included for fabricated items after handover?
  • Are contractual liability requirements met?
  • Does the policy respond to site-based work?

3. Employers’ Liability & Workforce Risks

Employers’ liability insurance is compulsory in the UK and particularly important in fabrication environments where injury risk is higher.


  • Is employers’ liability in place at £5m+?
  • Are all employees, apprentices and labour-only subcontractors included?
  • Do job descriptions reflect real duties?
  • Are welding fumes, dust and noise risks assessed?
  • Are training and competency records maintained?

4. Property, Machinery & Business Interruption

Fire, theft or flood can stop fabrication operations overnight. Property and interruption cover protects the assets and income you rely on.


  • Are buildings insured on a reinstatement (rebuild) basis?
  • Are contents, machinery, extraction and compressors fully valued?
  • Is stock insured at peak levels?
  • Is tools and portable equipment cover included?
  • Does business interruption reflect realistic restart times?

5. Environmental, Fire & Air Quality Risks

Pollution, fumes, dust and fire-related claims are increasingly scrutinised by insurers and regulators.


  • Are pollution exclusions understood in your liability policy?
  • Is environmental liability needed for your operations or location?
  • Are hot works permits and fire watch procedures in place?
  • Is fume extraction / LEV installed and maintained?
  • Are spill response and waste controls documented?
