You can expect a structured inspection and testing visit focused on safety, compliance, and clear record keeping. We will explain what we are checking, document the results, and talk you through any findings in plain English. Who is gas safety and certification best suited for? This category is ideal for homeowners who want reassurance, landlords who need compliant records for tenancies, and small commercial sites managing ongoing responsibilities. It is also suitable if you have concerns about appliance performance, odours, or potential leaks. How often should gas safety checks be carried out? Frequency depends on your responsibilities and the type of property, but landlords are typically required to arrange checks at least every 12 months. For owner-occupiers and businesses, regular checks are recommended and may be guided by appliance instructions, insurance requirements, and risk. Will I receive documentation after the visit? Yes. Where certification or reporting is required, you will receive clear paperwork summarising what was checked, the test outcomes, and any actions needed. This can be kept for your records and shared with tenants, managing agents, or insurers as appropriate. What happens if an issue is found during the checks? If a safety concern is identified, we will explain the risk level and the safest next step, which may include isolating the supply to prevent danger. You will then receive clear options for resolving the issue, so you can make an informed decision.
