Business Finance Guide

Which Business Finance Product Is Right for You?

A practical decision tree for UK SME owners and finance directors. Match the right funding structure to the right problem - and avoid the expensive defaults.

14 min read

Most UK businesses raise capital badly. Not because they pick a bad lender, but because they pick the wrong product structure for the problem they are actually solving. A merchant cash advance to fund a piece of equipment, an overdraft to fund an acquisition, an asset loan to fund working capital - each of those is a structural mismatch that ends up costing meaningful money over the life of the facility.

This guide is a practical decision tree. It maps the eight most-used UK business finance products against the commercial problems they were designed to solve, with honest guidance on which to use when and which alternatives to consider. It is written for SME owner-managers, FDs and CFOs who already understand their business and want to understand the funding market.

There is no recommendation algorithm here. The right answer depends on your trading profile, what security is available, how fast you need the cash, how long you need to keep it and what the realistic exit looks like. The job of this guide is to put those variables in front of you so you can have a sharper conversation with whoever ends up arranging the facility.

Start here: the five questions that decide the product

Before you talk to any lender or broker, answer these five questions about your funding need. The answers collapse the product choice from eight options down to one or two.

  • How much do you need to raise? Sub-£100k, £100k-£500k, £500k-£2m or £2m+?
  • What is the cash for? Single asset, working capital, growth investment, acquisition, refinancing, opportunity, tax, dividend?
  • How long do you need it? Sub-12 months, 1-5 years, 5-25 years?
  • What security can you offer? None (unsecured), the asset itself, debtors, property, director real estate, group debenture?
  • What does the exit look like? Trading cash flow, contracted receivable, refinance, sale, capital event?
The wrong product is worse than no product

A 36-month merchant cash advance dressed up to fund a 5-year asset acquisition typically costs three times what the right structure would. Get the product question right before you negotiate price.

Business term loan: the workhorse

A business term loan is the simplest and usually cheapest form of structured business debt. The lender advances a lump sum that you repay in equal monthly instalments at a stated APR over 1-7 years. It can be unsecured (PG backed) or secured (property, debenture, asset charge).

Term loans suit growth investment, defined-purpose capital expenditure that doesn't suit asset finance, acquisitions where security is available, and refinancing of multiple smaller short-term facilities. They are well-suited to predictable, profit-generating uses where the monthly repayment can be planned for at the outset.

What they are bad for: short-term working capital pressure (use an RCF), single-asset purchases (use asset finance), or any situation where you might need to repay early without penalty.

  • Loan size: £25k to £5m+ unsecured; £100k to £25m+ secured against property
  • Term: 1-7 years unsecured; up to 25 years secured against property
  • Pricing: 6-15% APR unsecured; 5-9% APR secured against property
  • Decision speed: 2-5 working days unsecured; 3-6 weeks secured

Revolving credit facility (RCF): the working capital line

An RCF is a pre-approved line of credit you can draw down, repay and redraw repeatedly across the agreement, typically 12-36 months. You pay interest only on the drawn balance plus a small non-utilisation fee on the undrawn portion. It is the modern replacement for the traditional bank overdraft.

RCFs are designed for working capital: smoothing payroll, paying suppliers early, covering VAT and corporation tax timing, funding stock builds, taking on contracts with extended payment terms, or simply holding dry powder for opportunistic moves.

What RCFs are bad for: anything where you need the full headline limit drawn for the entire term. If you are going to be permanently 100% drawn, a term loan is cheaper.

  • Facility size: £25k to £5m+
  • Term: 12-36 months, renewable
  • Pricing: margin over base rate on drawn balance; 0.5-1% non-utilisation fee
  • Decision speed: 1-2 weeks
RCF vs overdraft

An RCF is contractually committed for the agreed term. A bank overdraft can be withdrawn on 30 days' notice. For any meaningful working capital requirement, the RCF is structurally safer.

Asset finance: for the kit your business runs on

Asset finance funds the purchase of identifiable equipment, vehicles or plant by spreading the cost over the useful life of the asset. The asset itself secures the loan, which collapses the risk and the price. It comes in four flavours: hire purchase (own at end), finance lease (off balance sheet), operating lease (return at end) and sale-and-leaseback (release capital from owned kit).

Asset finance is almost always cheaper than the equivalent unsecured business loan for a single asset purchase. Where you would pay 10% on an unsecured loan, you might pay 6-7% on the equivalent asset finance because the lender has hard collateral.

What asset finance is bad for: intangible assets, multiple small items below £5k each, soft assets with poor secondary market, or working capital generally.

  • Loan size: £5k single asset to £10m+ fleet builds
  • Term: 1-7 years aligned to asset useful life
  • Pricing: typically 200-400 basis points below equivalent unsecured loan
  • Decision speed: same day to 5 working days

Invoice finance: turn unpaid invoices into cash

Invoice finance advances 80-90% of the value of unpaid customer invoices, typically within 24 hours of the invoice being raised. The remainder (less a small fee) is released when the customer pays. It comes in two main forms: factoring (disclosed - the funder manages credit control) and invoice discounting (confidential - you continue to manage the ledger).

Invoice finance suits businesses with predictable B2B trade-credit sales cycles where customers genuinely pay on 30-90 day terms and the business needs cash faster than that. Manufacturing, wholesale, recruitment, construction, professional services, logistics and printing are all classic invoice finance users.

What invoice finance is bad for: consumer-facing businesses, cash trading, project work with milestone billing, or one-off contract wins. It is also expensive relative to a term loan if you are using it as permanent working capital rather than a genuine cash flow accelerator.

  • Facility size: scales with debtor book; typically 80-90% of approved invoices
  • Term: rolling, 12-month commitment renewable
  • Pricing: service fee 0.3-2% of turnover plus discount fee on advance
  • Decision speed: facility setup 1-2 weeks; ongoing advance within 24 hours of invoice

Merchant cash advance (MCA): fast, expensive, contextual

An MCA is a sale of future card receipts. The funder advances a lump sum and recoups a fixed percentage of each card transaction until a pre-agreed multiple of the advance is repaid. There is no fixed monthly payment and no stated APR, but the implied cost typically equates to 30-60% APR on an annualised basis.

MCAs suit retail, hospitality and consumer-facing businesses with strong, predictable card turnover that need short-term cash and cannot wait for a term loan. They are also useful for businesses that have already exhausted other options and need bridging working capital while a longer-term facility is arranged.

What MCAs are bad for: anything that can wait 5-10 working days for a cheaper alternative. The implied cost is significantly higher than a term loan or RCF, and the daily repayment can suffocate cash flow if turnover dips.

  • Advance size: typically 80-150% of monthly card turnover
  • Repayment: fixed percentage of daily card receipts, no fixed monthly
  • Pricing: factor of 1.15-1.50 on advance (effective APR 30-60%)
  • Decision speed: 24-48 hours
Use MCAs as a last resort, not a default

An MCA is the right tool when you are funding a short-term, high-return commercial moment and a term loan simply cannot complete in time. It is the wrong tool when you have 5-10 working days to arrange something cheaper.

Commercial bridging: short-term, property-secured

A commercial bridging loan is short-term funding (3-18 months) secured against property the business or directors own. The cash itself goes into the trading entity for whatever the commercial purpose is - acquisition, VAT, tax, refinance, opportunity, working capital. Interest is usually rolled or retained so there is no monthly service.

Commercial bridging suits time-sensitive deals where speed beats price: acquisitions on tight deadlines, HMRC pressure, contractually-imposed refinance windows, off-market opportunities and any situation where the value created by acting fast outweighs the higher monthly cost.

What bridging is bad for: anything where you have time for a term loan or commercial mortgage. Bridging is more expensive precisely because it is faster and more flexible. Use it deliberately, with an engineered exit, not as a default.

  • Loan size: £100k to £25m+
  • Term: 3-18 months
  • Pricing: 0.65-1.25% per month, usually rolled or retained
  • Decision speed: 2-4 weeks completion

Commercial mortgage: long-term property finance

A commercial mortgage is long-term debt secured against UK commercial property, used to purchase the property, refinance existing debt or release equity. Terms run 5-25 years at rates of 5-9% APR depending on the asset, sector and LTV. It is the cheapest form of business borrowing the UK market offers, full stop.

Commercial mortgages suit owner-occupier purchases (rather than renting premises), property investment, refinancing higher-cost short-term debt and equity release from owned property to fund growth or acquisitions.

What commercial mortgages are bad for: anything that needs to complete in under 6 weeks. The valuation, legal and underwriting cycle is slower than a bridge. For speed, bridge first then refinance onto the long-term mortgage.

  • Loan size: £100k to £25m+ (and beyond on syndicated)
  • Term: 5-25 years
  • Pricing: 5-9% APR depending on asset, sector, LTV
  • Decision speed: 6-12 weeks

The decision tree, end to end

Map your need against this sequence. The first match is usually the right product. Where two products both fit, the cheaper one wins.

  • Buying a single piece of equipment, vehicle or plant -> asset finance
  • Need working capital that flexes month to month -> RCF
  • Need to accelerate cash on unpaid invoices -> invoice finance
  • Need to buy or refinance commercial property over 5+ years -> commercial mortgage
  • Need short-term, property-secured cash for a commercial purpose with a clear exit -> commercial bridging
  • Need a lump sum for defined-purpose growth with predictable monthly repayment -> term loan
  • Card-trading business, need cash in 48 hours, term loan too slow -> MCA
  • Need to release equity from owned property to fund the trading business -> property-backed business loan or commercial mortgage refinance

The five most common product mismatches

After 20+ years of arranging UK business finance, these are the structural errors we see most often. Each one is avoidable.

  • Using an unsecured term loan to buy a single asset when asset finance would price 2-4% cheaper.
  • Using a merchant cash advance for anything other than genuinely urgent card-trading cash needs.
  • Using a bridging loan as long-term debt because the bank refused term finance, instead of fixing the term finance.
  • Stacking three or four short-term unsecured loans on top of each other rather than consolidating into a single longer term facility.
  • Refusing to put up property security because of personal preference, then paying 50% more on unsecured pricing across the life of the facility.
The bigger the facility, the more the structure matters

On a £50k loan, picking the wrong structure costs you a few hundred pounds. On a £2m facility, it can cost £100k+ over the life of the deal. Spend the time getting the structure right before you negotiate price.

Next steps

If you have a specific commercial problem to solve, send us a one-line brief: amount, purpose, security, term, exit. We come back within hours with which product structure suits, which lenders are genuinely open to it, what indicative pricing looks like and how fast it can complete.

If you are earlier in the conversation and want to think through the right structure before committing to anything, the same one-line brief still works. We will run the comparison and tell you honestly if the answer is one of the products you already had in mind, or something cheaper you had not considered.

Either way, all conversations are confidential and no upfront fees are charged on facilities over £1m.

Key takeaways

The five things to remember

  • Pick the product structure before you pick the lender. The structure decision drives roughly half the total cost of the facility over its life.
  • Asset finance beats an unsecured loan for any single-asset purchase. Always.
  • An RCF beats a term loan for any working capital need that genuinely flexes month to month.
  • Bridging is a precision tool for short-term, property-secured commercial moments. Not long-term debt by accident.
  • Property-backed business loans are almost always the cheapest growth capital available to a UK SME with usable real estate security.
