Navigating the waters of main contractor insolvency: A toolkit for lenders, investors and developers
In 2024, it was reported that the average profit margin of the top 100 main contractors in the UK was just 1.87%1 . Whilst this improved in 2025 (to 2.4%2 ), clearly, it doesn’t take a lot for this profit margin to be challenged, and it is no surprise that construction firms accounted for 16% of all insolvencies in England and Wales in Q2 20253 (and currently tracking at 17% for 20264).
The insolvency of a main contractor poses a significant risk in real estate development and built environment projects, challenging feasibility through delays, increased costs, and legal complications. Anecdotal evidence from industry experts suggests that contractor insolvency is responsible for an average project delay of three to six months and cost overruns of up to 20%.
This article aims to guide Lenders, Investors, and Developers through the early detection of financial distress, legal implications, and strategies for managing such situations effectively.
Part 1: Optimising your project from the outset
Before entering into contracts, Contractors, Lenders and Investors should rigorously assess the financial health of a proposed Main Contractor, employing a multifaceted approach. This includes:
Reviewing financial reports and conducting covenant strength tests
Looking at liquidity ratios, profitability margins, and cash flow trends, as well as any significant year on year trends
Credit reports from reputable agencies can reveal the contractor's credit history, including any defaults or late payments
Obtaining references from previous clients and suppliers to obtain a ‘real world’ insight in the contractor’s stability
Consulting with professional advisors familiar with the market – questions to ask professional advisors might include:
“What is this contractor's history of dispute resolution?”
“How does the contractor's cash flow management compare with industry standards?”
“What other major projects does this contractor have on at the moment?”
Advisors may also have other anecdotal information which, whilst it must be taken with caution, can be a useful tool to understanding the real risks of appointing any given Main Contractor.
Contractual Protections – legal provisions can provide the Contractor with options to take control of the situation and be proactive in the face of issues.
Suspension and termination: Ensure contracts include clauses that allow for suspension and termination in the event of contractor insolvency. Ensure insolvency is defined broadly – one client I’ve worked with didn’t have the levers they needed in the event of ISG’s administration, giving rise to the need for some careful strategic advice to navigate the issue quickly so as to avoid significant delays to a time-sensitive project.
Escrow accounts and project bank accounts: Consider escrow accounts or project bank accounts that control the flow of funds. Discuss the use of a DiPPA5 . This ensures that payments flow to the right party once work is completed and can protect against misallocation of funds and cashflow black holes when the Main Contractor falls over
Regular financial monitoring: Financial scrutiny is too often only performed at the tender stage. Continuously monitor the contractor’s financial health throughout the project. Some projects last years, and financial health can change fairly quickly in that period
Milestone payments: Avoid upfront payments (certainly not without very strong protection in the form of a bond). Structure payments based on the achievement of specific project milestones (signed off by the certifying consultant). This aligns payments with progress and can help manage cash flow effectively, reducing the amount ‘held’ by the Main Contractor at any given time
Retention mechanisms: (Until we’re no longer able to6) utilise retention mechanisms. With margins so low, a retention provides very real incentive to ensure project completion and can act as a financial buffer in case of contractor issues
Performance security: Performance bonds and parent company guarantees can offer something of a financial safety net, ensuring that funds or resources are available to assist with completing the project should the contractor face financial difficulties. Any restrictions or issues with the Main Contractor being able to obtain a performance bond can often in itself be an indicator that the surety market sees the contractor as a risk – or that the contractor’s bond capacity is already stretched, which may suggest its resources and finances are similarly leveraged. Protection under a PCG can be undermined if a whole company group goes under, of course, and it is crucial to ensure the correct entity is used (beware the ‘shell’ holding company)
Subcontractor management: Directly monitor and, if necessary, approve the appointment of key subcontractors to ensure they are financially stable and capable of completing their portion of the work
Change order management: Implement strict controls on change orders to avoid scope creep and uncontrolled increases in project costs, which can strain the contractor’s financial capacity and cashflow
Contingency planning: Develop and maintain a robust contingency plan that includes scenarios for contractor insolvency. This plan should outline steps for engaging alternative contractors or taking other remedial actions swiftly to minimise project disruption
Open communication lines: Maintain open and transparent communication with the contractor to encourage early reporting of potential financial difficulties. This can facilitate proactive management of emerging issues before they escalate into insolvency
Part 2: The writing is on the wall
Recognising the early warning signs of a Main Contractor's insolvency is crucial to mitigating risks and safeguarding the integrity of your projects. The ability to identify these signs early on can mean the difference between a project's success and a costly, time-consuming failure. Here are some key indicators that a Main Contractor may be having issues:
One of the most telling signs is when a Main Contractor begins to delay payments to subcontractors and suppliers. This not only signals cash flow problems but can also lead to liens against your project, disrupting the supply chain and potentially halting construction.
A noticeable decrease in the pace of work, without justifiable external factors, can indicate that the Main Contractor is struggling to manage resources effectively, possibly due to financial constraints.
If a Main Contractor starts requesting advance payments or changes the terms of payment to earlier stages than previously agreed upon, it may be a sign they are trying to manage cash flow issues. While occasional requests may not always signal trouble, a pattern of such requests should raise red flags.
Frequent and unexplained shortages of labour and materials can suggest a Main Contractor is unable to meet its financial commitments to hire labour or purchase materials.
A sudden drop in the Main Contractor's willingness to communicate openly about project progress, financial matters, or challenges can be a sign of underlying issues. Transparency is key in any construction project, and a lack of it can indicate they are hiding potential financial problems.
These are all signs in a drop in investment and resourcing, and can in turn lead to plant breakdowns, an increase in on-site health and safety incidents, and theft of materials; all of which result in further time and costs implications.
By staying vigilant and monitoring these early warning signs, sophisticated Contractors can take proactive steps to assess the situation, implement contingency plans, and engage in discussions with the Main Contractor to address potential issues before they escalate into full-blown crises.
Part 3: Imminent Insolvency
Engage with legal counsel straight away – insolvency may trigger specific clauses within a well drafted construction contract, but navigating these clauses (and the requirements of insolvency law) must be done carefully to avoid wrongful termination, invalid notices, or falling foul of applicable laws.
In certain circumstances it may be possible to put a stop to outgoing payments – but again this must be very carefully administered.
There will be a balance between wanting to simply terminate the contract and move to the ‘rescue phase’ of a project, against the risks of rushing ahead.
Assemble a Crisis Management Team: comprising senior management, legal advisors, on-site project team, and communication specialists to oversee the response to the contractor's insolvency.
Performance bonds and guarantees: If the contractor provided a performance bond, communicate early with the surety and initiate the process to claim these funds as soon as appropriate. Keep a note of the date of expiry of the bond; it can come around quickly when projects are in distress
Review insurance policies: Examine existing insurance policies for coverage that may apply to losses resulting from the contractor's insolvency, and initiate claims as appropriate. Note that delay in start up insurance requires there to have been some sort of physical damage causing the delay – but business interruption cover operates entirely differently and may offer some protection
Subcontractor engagement: Engage directly with subcontractors to assess their willingness and ability to continue their work. In some cases, the Contractor may need to negotiate new contracts directly with subcontractors or ensure their payment through project bank accounts to maintain project momentum
Assess and adjust financial reserves: Review the project's financial reserves and contingency budgets to accommodate the additional costs associated with completing the project without the original contractor. This may involve renegotiating terms with lenders or seeking additional financing
Insolvency proceedings: The Contractor must navigate the legal landscape of insolvency proceedings, which may involve asserting claims in the contractor's insolvency to recover any amounts owed for breach of contract or unfinished work. Participation in these proceedings is governed by insolvency laws and requires timely and proper filing of claims to protect the Contractor's interests
Creditors’ meetings: Participate in creditors' meetings and insolvency proceedings to represent the Contractor’s interests, potentially recovering some of the losses or negotiating terms that favour the project’s completion
Documentation and claims: Prepare and submit any claims against the insolvent contractor’s estate promptly, ensuring that all documentation is accurate and comprehensive to maximise the potential recovery
Planning for the future
Alternative contractor arrangements and options for project completion
Options for project completion include hiring a replacement contractor or switching to a construction management model. A comparative analysis of these options, considering financial and timeline implications, can aid in making an informed decision:
Traditional procurement: this involves appointing a new contractor to complete the construction based on existing detailed designs and specifications. This option allows for greater control over the quality and cost of the remaining works but may require more time to tender and mobilise a new contractor
Management contracting: the Contractor hires a management contractor to oversee the completion of the project. The management contractor coordinates all construction activities, hiring and managing subcontractors (trade contractors) directly on behalf of the Contractor – but crucially does not take direct delivery risk for the project (which remains with the Contractor). This option can offer flexibility and potentially faster project completion since work packages can be let individually. However, it requires a high level of oversight and management from the Contractor
Construction management: this involves the Contractor taking a more active role, with a construction manager acting as an agent to advise on and manage the construction process. The Contractor contracts directly with trade contractors, while the construction manager coordinates the works. This approach offers high levels of flexibility and control but places significant management and coordination responsibilities on the Contractor
Design and build with a new contractor: This can be an effective approach if the project is at an early stage or if significant design work remains. The new contractor would assume responsibility for both design and construction, providing a single point of responsibility. However, finding a contractor willing to take over a partially completed project can be challenging and will come at a premium cost
Direct appointment of subcontractors: If the Contractor is willing to take on more direct delivery responsibility, it may be possible to complete the project by directly appointing subcontractors to carry out the remaining works. This approach requires the Contractor to assume the role of the Main Contractor (including all of the CDM and Building Regulations requirements that involves), managing contracts and coordinating works directly. While offering maximum control, this option demands significant management input and construction expertise from the Contractor
Joint venture or partnering: finding a JV or other partner (likely another contractor or development company) can provide the necessary resources and expertise to complete the project. This approach can spread the risk and bring additional financial stability and construction expertise to the project. However, it requires careful alignment of interests and objectives between the parties – the incoming partner will need a financial incentive to taking the reins
Stakeholder engagement
Effective communication with all stakeholders is essential. Templates for stakeholder notifications can ensure consistent and clear messaging, helping to maintain project momentum and stakeholder confidence. It is also critical in managing the fallout from such events, mitigating rumours, and maintaining stakeholder trust.
Immediate internal coordination:
Develop a unified message: Craft a clear, concise message that outlines the known facts about the contractor's insolvency and the steps the Contractor is taking in response. This message should be consistent across all communications to prevent misinformation.
Present a clear action plan:
Map out stakeholders: Identify all stakeholders affected by the contractor's insolvency, including investors, lenders, subcontractors, suppliers, regulatory bodies, and the project's end-users
Prioritise communications: Determine the order and method of communication for each stakeholder group based on their level of impact and interest in the project
Outline mitigation strategies: Develop and share a comprehensive plan detailing how the Contractor intends to manage the contractor's insolvency, including timelines for appointing a replacement contractor and any adjustments to project milestones
Demonstrate control: Show stakeholders that the situation is being managed effectively, with a focus on minimising financial impacts and keeping the project on track
Immediate and transparent communication:
Notify Stakeholders (especially lenders) Promptly: Inform lenders or funders of the contractor's insolvency as soon as it becomes known, along with any immediate impacts on the project. Delay in communication can erode trust and complicate negotiations
Provide Regular Updates: Keep lenders informed of developments, including steps being taken to address the insolvency, replacement contractor options, and any changes to project timelines or budgets
Tailored messaging for different stakeholders:
Investors and Lenders: Reassure these groups about the steps being taken to protect their investment and the overall financial health of the project. Discuss any potential impacts on timelines and returns
Subcontractors and Suppliers: Address concerns regarding outstanding payments and the continuation of work. Outline plans to secure the project's completion and how they fit into these plans
Regulatory Bodies: Inform them of the insolvency and your plans for compliance with all regulatory requirements during the transition period
End-Users (Buyers/Tenants): Reassure them about the measures in place to minimise project delays and ensure quality standards are maintained
You survived, but is the system working?
The strategies outlined above offer a robust framework for managing the complexities of Main Contractor failure. Yet, as we delve deeper into these solutions, a fundamental question emerges, challenging the very foundations upon which our contractual relationships are built: Is it time to rethink our approach to construction contracts?
Alternative pricing models such as target cost contracts7 present a compelling vision for a more resilient and equitable construction industry. By aligning the interests of Developers, contractors, and financiers towards shared objectives of project success and financial stability, these models foster a collaborative environment where risks and rewards are more evenly distributed. But any shift represents more than a contractual adjustment; it signifies a transformation in how we conceive project delivery and risk management. It invites us to envision a future where the construction industry is characterised by stronger partnerships, enhanced transparency, and a shared commitment to project success.
