Construction finance

Construction runs on timing. Materials have to be bought and labour paid long before a certificate is signed off, a stage payment lands, or retention money is finally released. That gap between spending and getting paid is where many otherwise healthy contractors, subcontractors and developers run into cashflow pressure, even when the order book looks strong.

Lending Box is a whole-of-market broker, not a lender, working with UK limited companies, PLCs and LLPs in construction. We compare options across the market to find finance that fits how building businesses actually get paid, from asset finance for plant and vehicles to invoice finance against certified applications. We can't promise approval or a particular rate, but we can show you what's realistic before you apply.

How construction businesses use finance

  • Bridging the gap between buying materials and receiving a stage payment
  • Funding retention periods, which can tie up 3–5% of contract value for months
  • Buying or leasing plant, vehicles and tools without draining working capital
  • Covering payroll and subcontractor (CIS) payments on large contracts
  • Funding mobilisation costs at the start of a new project
  • Paying a VAT or corporation tax bill without disrupting site cashflow
  • Smoothing income between projects when work is seasonal or project-based
  • Funding growth into larger contracts that need more working capital upfront

Funding types that often fit

  • Invoice finance

    Advances cash against certified applications for payment or invoices owed by main contractors, so you're not waiting 30–90 days to get paid.

  • Asset finance

    Spreads the cost of plant, vans, diggers or tools, using the asset itself as security rather than tying up cash.

  • Working capital finance

    General-purpose funding to cover materials, wages and overheads between payment milestones.

  • Unsecured business loans

    A lump sum for mobilisation costs or growth, repaid over a fixed term without needing property security.

  • Bridging loans

    Short-term funding secured against property or land, useful for development-adjacent construction businesses needing fast completion.

What lenders look at for construction businesses

Construction is seen as a higher-risk sector by many lenders because of contract-based income, retentions and the sector's exposure to late payment. Lenders typically look beyond turnover alone at:

  • Contract pipeline and the spread of clients, so you're not reliant on one main contractor
  • How much of your revenue sits in retentions and how long they historically take to be released
  • Bank statements showing regular income despite lumpy invoice timing
  • CIS registration status and subcontractor payment history
  • Existing finance on plant and vehicles, and whether repayments look affordable alongside new borrowing

Sector challenges: retentions, payment chains and seasonality

Construction finance has to account for a few features that are specific to the sector:

  • Retentions held by main contractors or employers, often released only at practical completion or after a defects period
  • Long payment chains where delays higher up filter down to subcontractors
  • Seasonal slowdown over winter months affecting groundworks and external trades
  • Project-based income that makes month-to-month turnover uneven compared with other sectors
  • Rising material costs that can squeeze margins on fixed-price contracts

How to prepare a construction finance application

A well-prepared application gives a lender confidence despite the sector's reputation for volatility:

  • Have 3–6 months of business bank statements ready, plus your latest filed accounts
  • Summarise your current contract pipeline with values and expected completion dates
  • Be clear about outstanding retentions: amounts, clients and expected release dates
  • List any existing asset finance agreements and their monthly cost
  • Be ready to explain CIS deductions showing in your bank statements, as lenders will query these
