- When they apply retention
- Our business consists of two main routes to market. The first (and largest - by turnover, orders and numbers of contracts and approximately 80% of the totality of each of these measures) is our hire business. Within our hire business, other than in a small number of cases, construction contracts do not include a retention clause. The second is our sales business. Within our sales business, most construction contracts would include a retention clause.

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. Portakabin Ltd is at or below the median on that measure. The average days to pay sits over the median.
A worked example on a 30-day term: an invoice of £10,000.00 paid on this company’s average, 14 days after the final date, carries £45.07 of statutory interest at 11.75% plus the fixed sum, £145.07 in all, which the law lets you add without a clause. Run your own figures.
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. Portakabin Ltd is slower than the sector figure. 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.
