Clients check contractors. Contractors should check clients too.

Late payments, poor communication, unfair QS decisions and unapproved extras can destroy profit before a project even starts.

Construction loses more companies to insolvency than any other UK sector — around 4,000 firms a year — and late payment is the most common trigger.

  • Late payments destroy cash flow.
  • Poor QS decisions kill profit.
  • Slow communication delays projects.
  • Unapproved extras become disputes.
  • Contractors usually find out too late.

Every contractor learns the same lesson separately. CIX helps the industry learn together.

What CIX tracks

Six dimensions of project risk

Client Risk

How a client behaves through a project — decision-making, fairness and reliability.

Payment Behaviour

Patterns around on-time payment, retentions, delays and unpaid balances.

PM Risk

Project management quality — instructions, sign-offs, scheduling and coordination.

QS Risk

Quantity surveying fairness — valuations, deductions and contract administration.

Project Risk

Overall delivery risk — variations, scope creep and the likelihood of disputes.

Evidence Level

How well a report is supported — from basic notes to documented, verified evidence.

How It Works

Moderated, evidence-led, privacy-first

Every report follows the same governed process before it can be seen.

  1. 1

    Contractor submits report

    A verified contractor records their real business experience on a project.

  2. 2

    Evidence is uploaded or requested

    Supporting evidence is attached, or requested during moderation.

  3. 3

    CIX moderates the report

    Each report is reviewed before publication — nothing goes live automatically.

  4. 4

    Risk score is calculated

    Payment, communication, variation and dispute risk form an overall picture.

  5. 5

    Sensitive personal data is restricted

    Personal names and exact project addresses are never published publicly.

  6. 6

    Verified contractors access deeper reports

    Restricted detail is available to verified contractors where legally appropriate.

Public Summary

“Subcontractors report late payment, deductions that were not agreed, and extra work requested before costs were approved.”

How to read this

Scores summarise what subcontractors reported: payment gauges are built from real invoice delays, behaviour from contract conduct. Two or more abandoned invoices with a low payment score force the overall risk to High — and the evidence badge shows how well the reports are supported.

CIX reports are based on contractor-submitted experiences and moderated evidence. Reports indicate risk patterns, not legal findings.

Example only. Fictional data for illustration.

Warn others — and others will warn you.

Every project teaches you something about a client: who pays on time, who buries you in unapproved extras, who keeps their word. Right now that knowledge dies with the project. Share it — the next contractor won’t walk into the same trap, and someone else’s report may save you from yours.

Changed the company name, left the debts behind?

CIX links directors to their dissolved and liquidated companies — so a “brand-new” firm with an old track record can’t hide it.

And report the good ones too. A client who pays in 14 days deserves to be found. Good payers win better subcontractors, good subcontractors win better clients — that’s how the industry gets fairer, one honest report at a time.

Before you take the job, check the risk.
