How Iron Mountain (uk) PLC compares
Iron Mountain (uk) PLC takes an average of 20 days to pay its suppliers, which is 12 days faster than the UK median of 32 days across 9,336 reporting companies. 26% of their invoices fall outside the agreed payment terms, compared to a national average of 24%.
The “outside agreed terms” percentage measures how often the company pays after its own agreed payment terms, not against a fixed 30-day standard. A company with long payment terms can still be rated “Good payer” if it consistently meets those terms.
