What this means if you are pricing work for them
The share paid later than agreed is the number to read first, because a short term makes an invoice late sooner and a long one hides lateness inside the term. SSE Generation Ltd is at or below the median on that measure. The average days to pay sits under the median.
On a 30-day term this company’s average lands inside the term, so a late invoice is the exception. When one is late, the calculator shows what statutory interest and the fixed sum add, which the law lets you charge without a clause.
Against the official benchmark: the Department for Business and Trade’s statistics for 2025, published 14 July 2026, put large construction businesses at 33 days to pay with 14% of invoices late by number (13% by value), and all large businesses at 32 days and 15% late. SSE Generation Ltd is at or inside the sector figure on days. Its late share is at or below the sector figure.
What the register does not show: it is self-reported, large companies only, and the filing covers the whole company, not your contract. Read it alongside the notice rules that decide what you are actually owed, and keep your own dates.
