The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in year (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 37 candidate sentence(s) were refused by a reviewer with the reason recorded. Derivation as chartered: Two intervals that nobody publishes as one answer, each labelled with whether it is LAW or GUIDANCE. For portable appliances: the initial interval by equipment class and environment (hand-held against stationary, office against construction site against equipment hire), from HSE's own guidance - which says explicitly that no fixed interval is required by law and that the suggested tables are suggestions. For fixed installations: the maximum period between inspections by tenure and premises type (private rented 5 years by statute in all four nations, owner-occupied 10 years by guidance, HMO, commercial, industrial, caravan park, swimming pool), from the statute where a statute sets it and from BS 7671 / IET guidance where it does not. The derivation is the gap: how often the internet's stated interval is a guidance figure being repeated as if it were law.", "embed": "
