Construction business finance in 2026

Construction has more insolvencies than any other UK sector. But many of the firms at risk in 2026 are not short of work. They are short of the cash needed to fund that work before they get paid. For contractors, developers, installers and specialist trades, the challenge is often timing. Materials need to be bought before a job starts. Labour and subcontractors need to be paid as work progresses. Retentions can be held back long after the project is complete. At the same time, material prices are moving, margins are under pressure and lenders are scrutinising the sector closely. This guide explains where the construction sector stands in 2026, why cash flow gaps are such a persistent problem, and which finance products are most relevant for construction businesses trying to keep projects moving.

Where construction demand is holding up in June 2026

The overall construction sector picture is one of sharp divergence. New build activity is contracting, with private residential development particularly affected as mortgage rates remain high and developer confidence stays weak. The government’s target of 1.5 million new homes this parliamentary term looks increasingly remote, with planning bottlenecks and a renewed financing squeeze compounding regulatory complexity. 

But not every part of the sector is struggling. Repair, maintenance and retrofit work has held up well as homeowners continue to improve rather than move. Infrastructure output is growing, supported by energy generation contracts and the water sector’s AMP8 capital programme. Public sector pipelines also remain the lower-risk end of the market. For a fuller view of the wider economic context behind these trends, read our June 2026 Economic Outlook.

That mixed picture matters because construction businesses are not all facing the same conditions. A housebuilder exposed to private residential demand may be under very different pressure from a contractor working on infrastructure, maintenance or retrofit projects. The businesses best placed to weather 2026 are those that understand where demand is still resilient, price risk carefully, and make sure they have the working capital to deliver the work they win.

Materials, labour and fixed price contracts are putting margins under pressure

Cost pressures are rising again after easing from the 2021-22 highs. The Middle East crisis is pushing up prices for energy intensive materials such as steel, aggregates and cement. A new steel import tariff due in July 2026 will add further pressure. Labour costs remain the more persistent drag, with skilled trades wages continuing to outpace headline inflation.

For construction businesses, these pressures are difficult because costs often move after a job has already been priced. A fixed price contract can look profitable when it is signed, but if materials arrive at a higher cost than expected, the margin can disappear quickly. Once that happens, the impact is not limited to profit. It affects the ability to pay subcontractors, suppliers and staff on time.

This is the real credit risk in the sector. Construction insolvencies account for approximately 17% of all UK company failures, according to the Insolvency Service, the highest of any sector. The problem is not always a lack of demand. In many cases, it is the gap between committing to work, funding the project and waiting to be paid.

The working capital gap behind many construction insolvencies

Construction businesses have a long cash conversion cycle. Businesses often pay for materials and labour weeks or months before the client pays them. Retentions can also create a structural cash flow gap, with a portion of every contract typically held back for 12 months or more. Stage payments add another layer of pressure because invoices can only be raised at project milestones, rather than continuously as costs are incurred. That means a construction business can be busy, profitable on paper and still under cash flow pressure. A full order book does not pay suppliers if payment is still tied up in applications, retentions or delayed client approvals. This is why lenders look carefully at the sector, and why the right finance structure matters more in construction than in many other industries.

Capitalise’s own experience reflects this. “We recently worked with an installation specialist that was importing materials on long lead times and losing contracts as a result, they were effectively quoting around their own supply delays,” said Nick Richardson, Head of Funding at Capitalise. “A working capital facility gave them the headroom to hold stock and commit to delivery dates with confidence, which put them back in contention for work they had been turning away. Access to capital, rather than demand, is now the binding constraint for these businesses.”

That example is important because it shows how finance can be used positively. It is not only about solving a crisis. It can also help construction businesses buy materials earlier, avoid supply delays, quote more competitively and take on work they might otherwise have had to turn away.

The borrowing challenges specific to construction businesses

Construction businesses face a set of funding challenges that standard lending products do not always handle well. These are the issues lenders are likely to focus on when assessing an application:

• Long cash conversion cycles: You may need to pay for materials, labour and subcontractors weeks or months before the client pays you.

• Retentions: A portion of each contract is often held back for 12 months or more, creating a recurring cash flow gap even after the work has been completed.

• Stage payment timing: Invoices are usually linked to project milestones, which means income does not always arrive in line with costs.

• Material price volatility: Quotes agreed months before work starts may no longer reflect the actual cost of steel, aggregates, cement or other materials.

• Higher lender scrutiny: Because construction has the highest insolvency rate of any UK sector, lenders pay close attention to credit profile, contract quality, debtor risk and cash flow management.

These challenges do not mean construction businesses cannot access finance. They mean the application needs to be clear, well supported and matched to the way construction cash flow actually works.

Which finance products work best for construction businesses?

Not all finance products are suited to the same purpose. For construction businesses, the right option depends on whether you are funding a development, buying materials, waiting on certified applications for payment, managing retentions or investing in plant and equipment.

• Development finance: Development finance provides staged lending against a construction or property development project, typically covering up to 70% of build costs and drawn down as work progresses. This makes it relevant for developers, housebuilders and larger commercial contractors because the funding structure reflects how construction costs are incurred. Rather than receiving all the money upfront, businesses can access funds in stages as the project moves forward.

• Working capital finance: Working capital finance can provide the headroom to buy materials, hold inventory or manage supply volatility before client payment arrives. This can be particularly useful for specialist installers, fit-out contractors and SME builders that need to secure materials early or buy when prices are more favourable. For businesses dealing with long lead times, this type of facility can help them commit to delivery dates with more confidence.

• Invoice finance: Invoice finance can help unlock cash tied up in certified applications for payment, unpaid invoices and retention receivables. This is especially relevant for main contractors, subcontractors and firms with significant retention balances, because receivables are often one of the largest assets on a construction business’s balance sheet. Releasing cash from those assets can help bridge the gap between work completed and payment received.

• Trade credit: Trade credit allows construction businesses to buy materials, supplies or services from suppliers and pay for them at a later date, usually within agreed payment terms. This can be valuable when materials are needed before a client payment or stage payment has been received. Used carefully, trade credit can help contractors keep projects moving, manage short-term timing gaps and avoid using cash reserves too early in the project cycle.

• Asset finance for plant and equipment: Asset finance allows construction businesses to spread the cost of plant, machinery, vehicles and specialist equipment through leasing or hire purchase. This avoids large upfront capital outlays that can drain working capital. Because the equipment being financed usually acts as security for the lending, asset finance can be a practical option for contractors that need reliable equipment but want to protect cash for project delivery.

How construction firms can strengthen a funding application

The construction businesses best placed to secure funding in 2026 are those that can show lenders they understand their numbers, their contracts and their cash flow risks. Preparation matters because lenders are cautious about the sector, but that caution can be managed if the application gives a clear and credible picture of the business.

• Build a cash flow forecast around project timing. A forecast should show when materials are paid for, when subcontractors need paying, when applications for payment are submitted, and when cash is expected to arrive. This is more useful than a generic sales forecast because it reflects the actual funding gap in the business.

• Stress test material cost increases. Fixed price contracts are a major risk when material costs rise. Testing what happens if steel, aggregates, cement or other key inputs increase before delivery helps you understand whether the job still works and whether additional working capital is needed.

• Track retentions and applications for payment clearly. Lenders will want to understand how much cash is tied up, when it is expected to be released and whether there are any disputes. Clear records can make it easier to support an invoice finance facility.

• Check your business credit score before applying. Construction lenders scrutinise credit profiles closely because of the sector’s insolvency risk. Checking your business credit score early gives you time to understand how lenders may view your application, identify issues and approach the market with more confidence.

• Credit check customers and main contractors. Your cash flow risk increases when the businesses paying you come under pressure. Credit checking key customers, developers or main contractors can help you spot risk earlier and avoid being overexposed to clients that may delay payment.

• Compare lenders across the market. Your bank may not be the best fit for your situation, especially if you need a specialist construction finance product. Capitalise helps businesses check their business credit score, credit check customers, apply for a range of funding products and compare options from across the market.

What this means for construction businesses in 2026

Construction remains a challenging sector, but the picture is not uniformly negative. New build is under pressure, but infrastructure, maintenance and retrofit work are still showing resilience. Demand still exists for many firms. The question is whether they have the working capital, credit visibility and funding structure to deliver that demand profitably.

The businesses most at risk are often those caught between rising costs, fixed-price contracts, long payment cycles and retained cash. But these are not impossible problems to manage. With better forecasting, stronger credit visibility and the right finance product, construction businesses can reduce the pressure created by materials, labour and delayed payments before it becomes urgent.

For construction business owners, the most useful first step is to understand exactly where the pressure sits. That means reviewing your cash flow, project pipeline, debtor book, retentions, credit position and customer risk. Capitalise helps bring those areas together. You can check your business credit score to understand how lenders may view your application, credit check customers or main contractors to spot payment risk earlier, and compare funding options across the market based on what your business actually needs, whether that is development finance, working capital, invoice finance, trade credit or asset finance. That visibility gives you more control. Instead of waiting until a materials bill, retention gap or delayed payment creates pressure, you can see the risk earlier and understand which funding options may be available. With the right facility in place, construction firms can buy materials earlier, manage retentions, protect working capital and keep projects moving while they wait to be paid.
