We’ve analysed new lending data from across the UK construction and engineering sector, and what we’re seeing is a clear shift in how firms are using business finance. Rather than borrowing to grow, construction businesses are increasingly relying on loans to keep things running.
What Do Construction Firms Use Loans For?
Our data shows a significant imbalance between short-term survival and long-term investment:
61% of loans are used for working capital
Just 6% are used for growth and expansion
The sector accounts for 25% of all SME borrowing
This tells us that most construction companies aren’t borrowing to scale, but borrowing to manage cash flow.
What Funding Do Construction Businesses Use?
We’re seeing UK construction and engineering businesses rely on a mix of funding options:
Business loans for larger, structured borrowing
Invoice finance to unlock cash tied up in unpaid invoices
Business overdrafts for short-term flexibility
Asset finance for plant machinery and high-tech equipment
For many business owners, combining these products is key to managing uneven cash flow cycles.
Why is Cash Flow a Problem For Construction?
Cash flow challenges are particularly acute in the UK’s construction sector compared to others.
Common reasons include:
Long payment terms (often 30-90 days)
Delayed payments or disputes
High upfront raw material and labour costs
Project-based income rather than recurring revenue
This creates a gap between spending money and receiving it, and borrowing is often used to bridge that gap.
How Much Do UK Construction Businesses Borrow?
Metric | Value |
Average loan size | £80,081 |
Approval rate | 77% |
Access to funding remains relatively strong, but usage is clearly defensive rather than growth-focused.
What Does This Mean for Growth in Construction?
A sustained focus on working capital over investment can slow growth across the sector. Potential impacts include:
Fewer new projects
Delayed hiring or scaling of the business
Slower adoption of modern, digital construction methods
Construction businesses are clearly still accessing finance, but what’s changed is how they’re using it. The overwhelming focus on working capital suggests firms are dealing with ongoing cash flow pressures rather than investing in future growth.
For businesses comparing finance options, this underlines the importance of finding flexible products that align with short-term needs, while still allowing room to invest when conditions improve.
Philip Brennan, Founder and Managing Director of BusinessComparison, says:
“This new data reflects the reality for many small construction and trade firms: strong demand and opportunity on one hand, but significant financial strain on the other. Managing project timelines, upfront costs, and late payments can put real pressure on cash flow.
“What we’re seeing at BusinessComparison is a more cautious, survival-focused approach to borrowing. For the wider lending market, it highlights the need for solutions that support SMEs through volatility, not just during periods of strong performance.”
FAQs: Construction Business Finance in the UK
What is working capital in construction?
Working capital refers to the money needed to cover day-to-day operations, including wages, materials, and project costs.
Why are construction firms borrowing more?
Many firms are borrowing to manage cash flow gaps caused by late payments, rising costs, and project timelines.
Is it risky to rely on business loans for cash flow?
It can be if used long-term without a growth strategy. However, short-term borrowing is often necessary in construction.
What’s the best finance option for construction businesses?
It depends on the need:
For short-term gaps: overdrafts or invoice finance
For higher costs: business loans
For new equipment: asset finance
What Should Construction Businesses Do Next?
Based on this trend, we’re seeing a growing need for:
More straightforward cash flow forecasting
In Summary
Borrowing remains strong
Approval rates are healthy
Growth investment is low
Right now, construction companies in the UK are prioritising their financial stability, but the long-term question is when that shifts back toward growth.
About the Data
Proprietary data on real UK businesses and lending activity was collected between June 2025 and May 2026 by BusinessComparison partner Think Business Loans. ‘Approval rate’ refers to the proportion of businesses submitted to a lender for consideration and subsequently approved.
