Are the current categories of Immediately Dangerous, At Risk and Not to Current Standards (ID, AR and NCS) really that hard to understand? If something is declared At Risk, the householder has the personal responsibility to ensure the advice is acted upon quickly. Although there may not be an 'immediate' danger to life, circumstances can change to create an immediate risk out of an at risk scenario, which means the person responsible for that property should act to book up any remedial work needed.

Instead it is often the other way round, customers are telling us that an appliance is safe, because it has been working ok without harming anyone for twenty years, and pleading with us not to turn it off, or cap it off.
