Their standard terms, in their words
Our standard terms are 45 days from end of month of invoice (for suppliers and subcontractors). Terms for a limited number of subcontractors with a high labour element are 7-30 days. Several large suppliers of materials are on agreed terms of 75 days from end of month of invoice. Invoices must be received by 5th working day following month of invoice to be paid as that month terms. If the invoice is not received by this point, then the invoice will be processed and paid to terms based on the month the invoice was received.

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. Tamdown Group 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, 20 days after the final date, carries £64.38 of statutory interest at 11.75% plus the fixed sum, £164.38 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. Tamdown Group 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.
