The first big contract is where a construction business either levels up or comes unstuck. Not because the work is beyond them. Dorset is full of capable builders, groundworkers, electricians, and mechanical contractors who can deliver bigger jobs than they currently take on. What comes unstuck is the money: the gap between spending on a job and being paid for it grows with every step up in contract size, and a business funded for small jobs cannot safely deliver big ones.

This article covers how construction companies and trades across Dorset typically fund that step up, what the main products actually do, and one honest truth about turnover that saves a lot of disappointment. For a broader local overview, start with our guide to business finance in Bournemouth.

Stage payments and retentions: where the cash goes

On smaller jobs you invoice at the end and get paid reasonably quickly. On larger contracts the rules change. You work to valuations, submit applications for payment, and wait for certification before money moves. In between valuations, everything is funded by you: labour, materials, plant, fuel.

Then there are retentions. A slice of each payment held back, half typically released at practical completion and the rest sometimes a year or more later after the defects period. On thin margins, the retention can be a meaningful chunk of the actual profit on the job, sitting in someone else's bank account.

None of this is unfair in itself. It is simply how the industry works, and it means a growing construction business needs working capital that grows with it. The businesses that get into trouble are usually the ones that won the bigger contract without planning how to fund the gap between valuations.

Materials and subcontractors: the upfront problem

A bigger job means bigger upfront costs. Materials for the first phases often need paying for before the first valuation is certified, and merchant credit limits tend to lag behind your growth: an account limit that comfortably covered your old jobs can be swallowed by week two of a new one.

Subcontractors expect paying on time regardless of when the main contractor pays you, and paying them late is the fastest way to lose the good ones.

This is classic working capital territory, usually funded with an unsecured business loan sized against the contract: enough to cover materials and labour through to the point where valuations are flowing regularly. The key is arranging it when you win the job, or better still while you are pricing it, rather than mid-job when the pressure is already on.

Vans, plant, and tools

Vehicles and plant are the easy part, because they are exactly what asset finance was built for. Vans, trucks, diggers, dumpers, and telehandlers are hard assets with a strong resale market, which means wide lender appetite and sensible terms, for used kit as well as new.

Hire purchase suits kit you will run for years: pay a deposit, fixed monthly payments, and the asset is yours at the end. For plant you only need occasionally, hiring may still beat owning, and the honest comparison is utilisation: kit that sits in the yard most of the month is usually better hired. Our asset finance guide for Dorset businesses explains the main structures in more detail.

There is a third option worth knowing. If your business already owns vehicles or plant outright, asset refinance can release cash from them. For an established firm with a yard full of owned kit, that can fund the working capital for a bigger contract without any new unsecured borrowing.

VAT and tax bills

Tax bill funding is common in construction and there is no shame in it. CIS, VAT quarters, and corporation tax all land whether or not your applications for payment have been certified, and spreading a tax bill over a few months to protect working capital is a legitimate, widely used facility.

One caveat: funding a tax bill occasionally to smooth timing is normal. Needing to fund every tax bill is a sign the pricing or the payment terms on your jobs need looking at, and a decent broker should say so rather than just arranging the next loan.

Invoice finance for construction

Construction is the awkward one in invoice finance. Standard facilities often exclude it, because contractual debt, applications for payment, and the risk of set-off make construction invoices harder to fund than a simple trade invoice.

That does not mean it is off the table. Specialist construction invoice finance exists, funding certified applications for payment and understanding how the sector actually gets paid. For subcontractors working for solid main contractors on long payment terms, it can turn the most frustrating part of the industry into a manageable one. The lender pool is smaller and the setup more involved, which is exactly the kind of placement where using a broker earns its keep. Read our Dorset invoice finance guide for an explanation of how standard facilities work.

Why turnover alone does not demonstrate affordability

Here is the honest section. Construction businesses often have impressive turnover and are then surprised by what lenders offer. The reason is margin.

A builder turning over £800,000 a year might have £600,000 of that going straight back out on materials, plant, and subcontractors. The business lenders are assessing is really the £200,000 that remains, and the borrowing that figure supports is smaller than the turnover suggests. High turnover with thin margins is normal in construction, but it means affordability is driven by what sticks, not what flows through.

Understanding this before applying does two things. It sets realistic expectations, and it tells you what strengthens an application: evidence of margin. A job costing that shows the profit on the contract you are funding does more for an application than a big turnover figure ever will.

What construction lenders commonly request

The core pack is the same as any sector: the last six months of business bank statements, the latest filed accounts, and a clear reason for the borrowing. For contract-related funding, add the contract or order itself, the payment terms, and ideally a simple costing showing the margin. Our guide to what lenders look for when a Dorset business applies for finance covers the wider assessment in detail.

A documented pipeline helps too. Lenders know construction is lumpy, and a forward order book presented properly reassures them that this quarter's bank statements are not the whole story.

Directors should expect a personal guarantee on unsecured lending, and clean bank conduct matters here as much as anywhere: bounced payments and constant reliance on the overdraft ceiling are the first things an underwriter sees.

Frequently asked questions

Can I fund a van or digger through my limited company?

Yes. Vehicles and plant are among the most straightforward assets to finance, new or used, through hire purchase or a lease.

Can I borrow against a contract I have won?

Not against the contract directly in most cases, but a signed contract with a clear margin is strong evidence for a working capital loan sized to deliver it.

Can I get invoice finance as a subcontractor?

Possibly, through specialist construction facilities that fund certified applications for payment. Standard invoice finance often excludes construction, so lender selection matters.

Can I fund a VAT or tax bill?

Yes, this is a common and accepted use of business lending, typically spread over a short term to protect working capital.

I recently moved from sole trader to limited company. Does my old trading history count?

Lenders generally assess the limited company, but a demonstrable trading history as a sole trader in the same business helps, particularly if turnover carried across. Expect a more limited market until the company has its own track record.
