RGII 5-Year Competency Assessment

It confirms that a registered gas installer's competence is still current five years on. Passing it supports continued registration; it is not a qualification you earn once and keep forever. Treat it as evidence that your knowledge of standards and safety practice has not gone stale.

Questions are multiple choice, covering the full spread of gas work from regulations and combustion through to unsafe situations. Some test direct recall of figures and procedures; others describe a scenario and ask for the correct action or diagnosis. The official RGII website confirms the current format.

Those details are set by the awarding body and can change between assessment cycles, so they are not fixed here. Check the official RGII website for the current question count and duration before you book, and plan your revision around the confirmed format rather than second-hand figures.

Most candidates find the regulatory and unsafe-situation sections straightforward if they work to current standards daily. The usual difficulty is precision: exact test pressures, ventilation requirements and correct terminology. Experience helps, but experienced installers who have drifted into habits can be caught out by questions on current requirements.

Retake arrangements, waiting periods and any fees are set by the awarding body and are not stated here. Contact RGII or check its website for the current retake policy. If you do need to resit, use the result to identify which domain let you down rather than revising everything again.

Start with safety and regulatory requirements, since that domain carries the largest share and underpins the rest. Then work through combustion and ventilation, and pipework and testing, because those feed directly into fault diagnosis. Leave service and maintenance until last; it is largely applied common sense once the fundamentals are solid.

Two areas recur: unsafe situations, where people describe making safe without correctly classifying or reporting the defect, and testing, where tightness-test pressures and durations are misremembered. Ventilation calculations are the third. All three reward practising the actual procedure rather than reading about it.

Not necessarily. Current standards, manufacturer instructions and your registration body's published guidance cover most of the syllabus. Many installers revise effectively from their own site documentation and commissioning records. If you do buy a course, check it is up to date with the current edition of the standards.

Booking windows and centre availability vary, so check the official RGII website for current scheduling rather than relying on what colleagues tell you. Give yourself a realistic revision period, and avoid booking the assessment for a week when you are already carrying a heavy callout load.
