For a trades business, growth is often blocked by one specific thing: kit. You can't take on the bigger job without the right van, the right tools or the right certification-related equipment — and that's real money, usually more than sits comfortably in the business account. The question isn't whether to fund it, it's how. And the three common routes — a loan, an overdraft, or invoice finance — suit genuinely different situations.

A loan: for a specific, known cost

A business loan is the right tool when you know exactly what you're buying and roughly what it's worth to you. A van, a set of tools, a piece of equipment with a clear price tag. You borrow a fixed amount, pay it back over an agreed term at a fixed or known rate, and the asset starts earning for the business straight away. The advantage is predictability — you know the monthly payment, and it doesn't move around with how busy you are. The downside is that you're committed to that repayment whether the following few months are quiet or not, so it only makes sense once you're confident the extra kit will actually get used, not just once you fancy having it.

Many equipment suppliers also offer asset finance or hire purchase specifically for the item you're buying, which is worth comparing against a general business loan — it's sometimes cheaper because the lender has the asset itself as security.

An overdraft: for smoothing, not buying

An overdraft is a different tool entirely, and trades businesses often misuse it by treating it as a way to buy kit. It's really there for short-term cash-flow smoothing — covering the gap between paying for materials and getting paid on a job, or riding out a quiet fortnight. Using it to fund a £15,000 van means you're paying overdraft rates (usually higher than a loan) on a debt that doesn't clear in a few weeks like it's meant to. If you find your overdraft permanently near its limit rather than moving up and down, that's usually a sign it's being used to plug a hole a loan or an actual pricing fix should be dealing with instead.

An overdraft is for the gap between doing the job and getting paid for it. A van is not a gap — it's a purchase. Fund it like one.

Invoice finance: for a business waiting on its own money

Invoice finance is worth knowing about if your real problem isn't a lack of money so much as money that's tied up in unpaid invoices — common for trades doing bigger commercial jobs with 30 or 60-day payment terms. You borrow against invoices you've already issued but haven't been paid for yet, releasing most of the cash now instead of waiting weeks. It's not cheap, and it works best as a way to keep cash flowing while you wait to be paid for work already done — not as a way to fund a purchase you haven't earned the money for yet. If late payment rather than a lack of demand is your actual bottleneck, this is often a better fix than either a loan or an overdraft.

New versus used, and what it does to the maths

The funding decision doesn't stop at loan-versus-overdraft — what you actually buy changes the sums too. A brand-new van or machine costs more up front but comes with a warranty and years before it needs replacing, which suits a fixed-term loan well because you're not gambling on unknown reliability. A good used one costs less to finance and frees up borrowing headroom, but carries more risk of an expensive repair landing right when you need the vehicle most. Neither is automatically right — a business doing 40,000 miles a year on tight jobs leans towards new and reliable; one adding a second van for occasional bigger jobs can often make a used one work perfectly well. Factor the likely repair and downtime cost into whichever finance route you're comparing, not just the purchase price.

Reading the real cost, not just the monthly figure

Whichever route you pick, look past the headline monthly payment to the total cost of borrowing — the interest rate, any arrangement fee, and what happens if you want to pay it off early or if a job falls through and a payment's briefly missed. A slightly higher monthly figure with no early-repayment penalty is often better value than a cheaper-looking deal that punishes you for clearing it faster once business picks up. It's worth getting more than one quote; rates for the same loan amount can vary more between lenders than most owners expect, and a trades-focused broker or your accountant can often point you towards lenders who understand seasonal trade income rather than treating it as a red flag.

Matching the tool to the actual problem

The mistake most trades businesses make isn't choosing the wrong lender — it's not being honest about which problem they actually have. Need a specific piece of kit you're confident will pay for itself? Loan or asset finance. Need to smooth a genuinely short-term wobble? Overdraft, used sparingly and cleared quickly. Waiting on invoices that are slow to land? Invoice finance, alongside fixing the late payment problem itself, not instead of it. Get the diagnosis right first, and the right funding route usually becomes obvious.
