What Triggers an Update
Pages on this site are revised when one of the following actually happens — not on a fixed calendar:
- An OGRA tariff or regulatory change — a new determination affecting slab rates, GIDC, or service standards.
- An SNGPL or SSGC process notice — a change to how a service (payment, complaint registration, connection process) actually works.
- A confirmed user-reported correction — see our Corrections Policy for how these are verified.
- A scheduled periodic check — pages covering information that can drift over time (tariffs, contact numbers, procedures) are periodically re-checked against the primary source even without an external trigger.
Review Cadence
We don't operate on a blanket "refresh everything every X months" schedule — that produces exactly the kind of cosmetic date-stamping we're trying to avoid (see below). Instead, pages tied to regulated, changeable information (tariffs, taxes, official processes) are checked more frequently than pages describing something stable (what a consumer number is, how HHM is measured). The full verification process behind this is documented in Research Methodology.
Substantive vs. Cosmetic Updates
A substantive update changes what a page actually says — a corrected figure, a revised process, new information that changes the guidance given. A cosmetic editchanges how a page reads without changing what it says — fixing a typo, improving a sentence, adjusting formatting. Only a substantive update should ever be reflected in a page's displayed "last reviewed" or "last updated" status. This mirrors the distinction we draw between factual corrections and editorial improvements on our Corrections Policy page.
"Last Reviewed" Philosophy
A "last reviewed" or "last updated" date is only meaningful if it reflects something that actually happened on that date. A date that changes automatically every time a page is rebuilt, regardless of whether anything on it changed, doesn't tell a reader anything true — and readers (and search engines) eventually learn to ignore a signal like that entirely. Our commitment is the opposite: a displayed review date should only move when a real, substantive check or correction happened, so that when it does move, it means something.
