In short
Unsecured Business Loan for UK construction businesses combines a sector pattern Lendrly tracks closely with a finance type that has its own underwriting shape. Established SMEs with steady turnover needing flexible-purpose capital. In the construction sector specifically, the lenders that tend to fit are ones already comfortable with the construction cash cycle, asset profile and customer mix. Typical amounts sit at £1k to £500k for most smes, up to £1m with select lenders. and decisions usually land within often 24-72 hours; same-day for smaller automated decisions. Final eligibility, pricing and limits are set by the lender at underwriting and depend on the full trading picture.
What underwriters in the construction sector typically watch for
The list below is specific to UK construction businesses seeking unsecured business loan — distinct from the generic blockers for either the sector or the product on its own.
- Sole-trader subcontractors without limited-company accounts hit a lower ticket ceiling on unsecured lending — asset finance against the van and tools is usually the better lead product.
- Recent CCJs are more common in cyclical construction sub-sectors than the SME average and narrow the unsecured lender pool.
- CIS deductions complicate the affordability picture — lenders model gross turnover but want to see the net cash that's actually arriving in the bank.
- Concentration on a single main contractor is a flag for unsecured underwriting just as it is for invoice finance.
Documents that help in construction unsecured business loan applications
Lenders ask for slightly different documents depending on the sector. Expect to provide most of the following when applying for unsecured business loan as a construction business.
- Last 6 months of business bank statements showing gross receipts and CIS deductions separately if possible.
- Latest filed accounts plus current-year management accounts.
- CIS returns and HMRC reconciliations covering the same period.
- Director ID and details of existing finance facilities including any asset finance on plant or vehicles.
Timing the application
Construction cash cycles tend to drop into the autumn-winter quiet patch and recover from March onwards. Unsecured applications made in May-July often present a stronger 6-month rolling picture than the same application in November-January.
Worked example
A 4-year-old limited-company groundworks contractor with £1.4m turnover, clean director credit and around £150k of net cash through the books might pre-qualify for an unsecured term loan in the £30-80k range from iwoca, Funding Circle or a similar provider. Pricing on this profile typically sits in the low-to-mid teens APR-equivalent. Final terms are subject to full lender underwriting and affordability checks.

Practical lender tips for construction unsecured business loan
- Be open about CIS at first contact — most mainstream lenders have a standard adjustment for it, but a missed disclosure can cause a re-underwrite.
- If the contractor has both an invoice finance facility and an asset finance facility live, a small unsecured loan on top often works better than trying to extend either of the existing facilities.
