Builder loans: finance for small building firms

Small builders rarely run short of work. They run short of cash between buying materials, paying the team and waiting for a stage payment, often with CIS deductions taken off what does come in. Builder loans come in several forms, and the right one depends on the gap you are trying to close.

The short answer

Builder loans are finance products small building firms use for vans, tools and plant, materials and the gap before stage payments arrive. Asset finance usually funds equipment, invoice finance or a short-term loan covers cash tied up in completed work, and development finance funds building property to sell. Lenders assess your trading record, contracts and credit, and every loan is subject to status.

What are builder loans?

Builder loans is a broad name for the finance small building firms use to buy equipment and keep cash moving between jobs. Loans for builders fall into four groups:

  • Equipment finance. Hire purchase or leasing for vans, plant, tools and scaffolding, secured on the asset itself.
  • Cash tied up in work done. Invoice finance against what customers and main contractors owe you.
  • Short-term working capital. Unsecured loans or advances to buy materials or cover wages before money comes in.
  • Property building finance. Development finance for builders putting up or converting houses to sell.

Our construction finance guide covers the wider funding picture for the sector. This page focuses on the smaller firms and sole traders who make up much of it.

Why do builders run short of cash?

Building work puts cash out before it comes back in, and three features of the industry stretch the gap:

  • Stage payments. Under section 109 of the Housing Grants, Construction and Regeneration Act 1996, a party to a construction contract is entitled to be paid in instalments or stage payments, unless the contract says the work will take, or the parties agree it will take, less than 45 days. Section 106 takes contracts with a residential occupier, such as work on a homeowner's own house, outside these rules, so domestic jobs depend on what the contract says. Either way, you fund each stage until it is paid.
  • CIS deductions. GOV.UK says a contractor deducts 20% from payments to a registered subcontractor and 30% from an unregistered one, as advance payments towards tax and National Insurance. Until you reclaim or set them off, that money is not in your account. Our Construction Industry Scheme guide explains how it works.
  • VAT reverse charge. HMRC says the VAT domestic reverse charge must be used for most supplies of building and construction services between VAT-registered businesses reported within CIS. Ask your accountant how it changes your VAT returns and cash flow.

Add retentions held back by main contractors, materials bought on account and customers who pay late, and a profitable builder can still be short of cash.

How do builders finance vans, tools and plant?

Most builders use asset finance for anything with a resale value. The lender buys the van or machine and you pay for it monthly, so the asset is the main security and your working capital stays free.

  • Hire purchase. You own the asset once the last payment is made. Our guide to hire purchase explains how it works.
  • Finance lease. You use the asset for a rental and do not take ownership in the same way.
  • Refinance. Raising cash against plant or vans you already own.

For vans in particular, our van finance guide compares hire purchase, leasing and contract hire. More on the product type is in our asset finance guide.

How can a builder fund materials and stage-payment gaps?

There are two main routes, and which suits depends on whether you invoice businesses or homeowners.

Funding the gap between paying out and being paid
OptionHow it worksSuits
Invoice financeAn advance against invoices you have raised to business customersSubcontractors and builders invoicing main contractors, developers or councils
Short-term unsecured loanA lump sum repaid over months, usually with a personal guaranteeBuying materials for a job, or covering wages before a stage payment
Business overdraft or credit cardA limit you draw on and repaySmall, frequent gaps
Supplier trade accountMaterials now, pay the merchant laterBuilders with a good record at their merchant

Invoice finance in construction can be harder than in other sectors, because applications for payment, retentions and contra charges make invoices less certain. Some providers work with construction specifically, and some fund single invoices. Our invoice finance guide explains the basics, and our page on short-term business loans covers the loan route.

Do not borrow against a job that is losing money

A loan for materials helps a profitable job finish on time. If a job is underpriced, borrowing only adds interest to the loss. Check the margin first.

Which lenders fund small builders?

These lenders list construction, contractors or construction plant among the sectors or assets they fund, on their own sites. The table comes from their profiles in our lender directory, in alphabetical order, and is not a ranking.

What finance do builders use to build houses to sell?

If you are building or converting property to sell, the product is development finance, not a business loan. It is released in stages as a surveyor signs off the work, and repaid from the sale or a refinance. Affirmative Finance, for example, says it lends to developers of all kinds, from established companies to smaller builders, including first-time developers. Our guide to development finance explains how lenders assess a scheme.

What do lenders look for in a building firm?

  • How long you have traded, and filed accounts or tax returns for that period.
  • Bank statements that show regular income and how you manage outgoings.
  • Your order book: contracts, applications for payment and who your customers are.
  • Any existing finance on vans and plant, and your record of paying it.
  • Your personal and business credit, including any CCJs.
  • For a sole trader, your Self Assessment returns and CIS statements.

Sole traders can usually access asset finance and some short-term lending, but fewer lenders. Our guide to sole trader loans explains what changes when you are not a limited company.

Common questions

It is a general name for finance used by building firms: asset finance for vans and plant, invoice finance or short-term loans for working capital, and development finance for building property to sell.
Yes, though fewer lenders lend to sole traders than to limited companies. Asset finance and some short-term lenders accept sole traders; expect to show tax returns, CIS statements and bank statements.
Common options are a short-term unsecured loan, an overdraft, a trade account with your merchant, or invoice finance if you invoice business customers. Check the job's margin before borrowing against it.
They reduce the cash you receive, which lenders see in your bank statements. GOV.UK says contractors deduct 20% from registered and 30% from unregistered subcontractors, as advance payments towards tax and National Insurance.
Yes. Some providers list construction specifically, and some fund single invoices. Applications for payment, retentions and contra charges can make construction invoices harder to fund than others.
Yes, development finance. It is released in stages as the build progresses and repaid from the sale or a refinance. Some development lenders say they work with smaller builders and first-time developers.
