The rules for Gross Payment Status (GPS) have quietly shifted. As of April 2026, the margin for error has effectively disappeared.
In the past, losing your GPS was a 12-month setback. Now, HMRC has the power to revoke your status for five years if they find serious non-compliance or issues within your supply chain. For a subcontractor, this is a fundamental threat to your cash flow.
The 20% Problem
If you lose your status tomorrow:
- 20% of your invoice is withheld by the main contractor before it ever hits your bank.
- Tier 1 firms may stop inviting you to tender, as they increasingly avoid “high-risk” subbies without GPS.
- Five-year lock-out: You cannot reapply for 60 months, regardless of how quickly you fix the original mistake.
Why are firms losing their status?
It is rarely about “dodgy” accounting. Most revocations happen because of simple, avoidable back-office friction:
- One or two late CIS returns in a year can now trigger a full status review.
- A small, disputed VAT amount or a late Corporation Tax payment is often enough for HMRC to pull the plug.
- Under new 2026 “due diligence” rules, you are now expected to ensure your sub-contractors are compliant. If they aren’t, your own GPS is at risk.
Getting the Admin Out of the Way
Most Construction Directors are spread too thin. You are managing sites, sourcing materials, and chasing labor. Compliance often happens late at night at a kitchen table.
This is where the risk lives.
The most successful firms are moving their compliance away from the “site office” and into a dedicated environment. At Agility Outsourcing, we provide the back-office infrastructure to ensure your filings are hit, your subbies are vetted, and your GPS stays secure. We don’t run your site, but we do protect the cash flow that keeps it running.
