# Natural Gas Distribution Accreditation

The primary regulatory framework for natural gas distribution in the UK is overseen by Ofgem, the Office of Gas and Electricity Markets, which licenses and regulates gas distribution networks. However, individual engineers and installers working on gas systems should hold Gas Safe Register certification, the mandatory competency scheme for anyone carrying out gas work in the UK. The Gas Safe Register replaced Corgi in 2009 and is the only legally recognised body for gas safety certification. Additionally, organisations may pursue quality assurance through bodies such as the British Standards Institution (BSI), which offers ISO certification, or memberships with industry groups like the Institute of Gas Engineers and Managers (IGEM), though these are not statutory requirements. Understanding these distinctions helps clarify whether you're dealing with a large infrastructure provider (regulated by Ofgem) or smaller installation and maintenance companies (which must have Gas Safe Register engineers on staff).

Verifying a provider's credentials is straightforward and essential. You can check an engineer or company's Gas Safe Register status directly on the official Gas Safe Register website using their registration number or postcode search tool, which confirms they are legally permitted to work on gas installations. For larger distribution companies, you can verify their Ofgem licence status through the Ofgem website. Ask your provider for evidence of relevant qualifications before work begins, and check that any insurance certificates are current and comprehensive. This verification matters because only accredited engineers can legally undertake gas work, and using an unaccredited provider exposes you to safety risks, invalidates warranties, may breach building regulations, and can leave you without recourse if something goes wrong.

Accredited gas engineers and distribution companies typically charge a premium compared to unqualified alternatives, often 10–20% higher for labour and service calls, though this varies by region and complexity of work. This additional cost reflects the genuine
