Risk Assessment Description:

This gas boiler servicing and maintenance safety checklist template from Health & Safety Zone helps Gas Safe registered engineers and plumbing supervisors ensure safe, compliant boiler service work.

It covers the full range of safety dimensions: planning and documentation, competence, work environment, task‑specific hazards, boiler equipment checks, substances, personal protective equipment, collective safety measures, emergency provisions and post‑work completion. The checklist aligns with the Gas Safety (Installation and Use) Regulations 1998 and relevant HSE Gas Safety Guidance. It guides you through verifying risk assessments, confirming permits, isolating the gas supply, checking ventilation, inspecting burners, pressure relief devices, flues, gas detectors and ensuring proper PPE and fire safety measures.

Use this checklist for:

  • Pre‑service checks – confirm risk assessments, permits and engineer competence before work begins.
  • During the service – verify equipment condition, gas detection, ventilation and PPE throughout the task.
  • Post‑service sign‑off – ensure the boiler is made safe, records are updated and any issues are reported.

Each item is answered Yes, No or N/A – any No answer must be resolved before proceeding. Record responses on site, investigate any non‑conformities immediately, and retain the completed checklist as part of the boiler’s service history.

Fully editable and shareable — customise the questions to your site, download as a PDF and share with your team.

Compliant with: Gas Safety (Installation and Use) Regulations 1998; HSE Gas Safety Guidance.

What types of safety checklist can I create?

We are building specialist checklists across a wide range of subjects and industries — fire safety, workplace inspections, equipment and machinery checks, site inductions, vehicle checks, PPE, first aid and more. Browse by category to find the right one.

It depends on the activity and your risk assessment — many checks are daily, weekly or monthly, while others are done before each task or shift. Completed, dated checklists provide a useful record of your monitoring.

Are the checklists a substitute for a risk assessment?

No. A checklist is a monitoring and inspection tool that complements your risk assessments and method statements — it helps confirm that controls are in place and working. Use them alongside your risk assessments.
