Menzies’ ‘Fixing the Foundations’ report, published 3 June 2026 from a Censuswide survey of 250 UK construction and property finance decision-makers, puts a number on something the sector has felt for years: 93% of firms experience late payment, averaging 53 days overdue.
The second figure is harder to read calmly. 86% of respondents are in, or at risk of, serious financial distress within eight months.
Why late payment in construction matters right now
Fifty-three days overdue is not a delay; it is an unplanned credit facility that contractors extend without pricing it. On a business running at single-digit margins, the financing cost of that gap can exceed the profit on the work itself.
What makes the 86% figure credible rather than alarmist is the compounding mechanism. Late payment received becomes late payment passed on. A subcontractor waiting 53 days for certification cannot pay their supply chain on 30, and distress propagates downward through businesses with progressively thinner reserves.
The uncomfortable part is that most firms cannot see the problem early. Cash position is usually reviewed monthly against accounts that describe the past. By the time a cash-flow problem appears in management accounts, the decisions that caused it were taken six to ten weeks earlier.
Key takeaways
- 93% of UK construction firms surveyed experience late payment.
- Payments run an average of 53 days overdue.
- 86% are in or at risk of serious financial distress within eight months.
- Late payment compounds down the supply chain rather than stopping at one firm.
- Monthly management accounts detect cash problems weeks after they become unavoidable.
What this means for contractors, consultancies and SME AEC firms
For finance directors, the first task is converting a vague sense of tightness into a forecast. A thirteen-week rolling cash view built from live project data behaves very differently from a monthly accounts review, because it shows the gap before it opens.
For commercial managers, the lever is often internal rather than external. A meaningful share of late payment starts as late application: work done, value not applied for, or applied for with documentation that invites a query. That is controllable.
For SME contractors and consultancies, the structural risk is concentration. One slow-paying client representing a third of turnover is a different business risk from the same revenue spread across six. Visibility of that exposure is a reporting question.
Applications are the controllable half
Late payment often begins with late or disputed application. Tightening that cycle is faster than changing client behaviour.
Forecast weekly, not monthly
A thirteen-week rolling cash view shows the gap before it opens. Management accounts show it afterwards.
Know your concentration
Exposure to one slow payer at 30% of turnover is a structural risk, not a collections problem.
Cash-flow visibility: spreadsheets, point tools or one system?
Nearly every construction business forecasts cash somehow. The difference is whether the forecast is connected to what is actually happening on projects.
| Capability | Spreadsheets | Separate point tools | Quantim |
|---|---|---|---|
| Rolling 13-week cash view | Rebuilt manually | Finance tool, disconnected from projects | Built from live project data |
| Application and certification cycle | Email and manual log | Partial | Tracked against the project |
| Client concentration exposure | Rarely analysed | Hard to query | Reportable |
| Work-in-progress visibility | Monthly estimate | Separate from cost control | Continuous |
| Early warning on margin | At invoice stage | Fragmented | At stage level, in flight |
How Quantim helps
Quantim brings invoicing, cost control, profitability and cash-flow reporting into the same place as project delivery. That connection is the point: a cash forecast built from live project data is a forecast, while one assembled monthly from accounts is a history.
For firms in the 93%, the realistic goal is not eliminating late payment. It is shortening the controllable part of the cycle and seeing the uncontrollable part far enough ahead to fund it deliberately.
- Build a rolling thirteen-week cash view from live project and invoicing data rather than monthly accounts.
- Measure your own application cycle. Time the gap between work completed, value applied for and invoice raised — then close it.
- Report client concentration and ageing together so slow payers with large balances are visible as a structural exposure.

Request a demoFifty-three days overdue is not a delay. It is an unpriced credit facility that contractors extend to their clients, often costing more than the margin on the work.
“The revelation was not that clients paid late. It was how much of the delay started with us — applications going out five days after they could have. We fixed our half first.”

Checklist for practice leaders
- Build a rolling thirteen-week cash forecast from live project data.
- Measure the average gap between work completed and value applied for.
- Review debtor ageing alongside client concentration, not separately.
- Identify the three clients responsible for the largest overdue balances.
- Check that application documentation meets each client’s certification requirements first time.
- Agree an escalation point in days, and apply it consistently.
Frequently asked questions
Why are UK construction firms waiting 53 days to get paid?
The Menzies ‘Fixing the Foundations’ survey of 250 UK construction and property finance decision-makers found 93% experiencing late payment at an average of 53 days overdue. The causes are layered: contractual payment terms that are already long, certification and valuation disputes that pause the clock, and a compounding effect where firms paid late pay their own supply chain late. A meaningful share also begins with late or incomplete applications on the supplier side. The full findings are summarised by the CICM report on construction payment delays.
How do you manage cash flow in a construction business in 2026?
Move from monthly review to a rolling thirteen-week forecast built from live project data, so the gap is visible before it opens rather than after. Tighten the controllable half of the cycle: the time between work completed, value applied for and invoice issued, and the quality of application documentation. Then monitor debtor ageing alongside client concentration, because a large overdue balance with one client is a structural risk rather than a collections task.
Is late payment getting worse in UK construction?
The 2026 survey data suggests the problem remains severe and widespread rather than improving, with 93% of firms affected and 86% reporting distress or distress risk within eight months. Legislative reform is moving in the sector's favour — proposed 60-day payment caps and mandatory late payment interest would help — but firms should not plan on the basis of that timing.
Workload is rarely what ends a construction business. Cash is. The firms that come through 2026 in good shape will be those that shortened the part of the payment cycle they control and saw the rest coming.
