When a UK business needs funding—whether for expansion, seasonal cash flow, or fulfilling a major contract—the default move for most directors is to ask their bank.
However, high-street bank underwriting can be slow, rigid, and heavy on Personal Guarantees. The alternative commercial lender market has evolved significantly, offering funding structures that are often faster, more flexible, or lower cost.
The challenge is navigating the options: the lowest headline interest rate is rarely the cheapest facility once fees and drawdowns are calculated. Here is how modern UK business funding options actually compare.
Quick Comparison: Which Funding Fits Your Situation?
| You need to… | Usually best suited | Typical speed | Security / Guarantee |
|---|---|---|---|
| Cover a one-off purchase or project | Unsecured Term Loan | 2–5 Days | Director PG (often required) |
| Smooth seasonal or unpredictable cash flow | Flexible Credit Line (RCF) | Hours to days once set up | Director PG or Debenture |
| Bridge slow-paying customers (30–90 days) | Invoice Finance / Discounting | Days to set up, then 24h draws | Debtor book charge, sometimes PG |
| Buy or upgrade vehicles, plant, or machinery | Asset Finance (HP / Lease) | 2–4 Days | The asset itself |
| Release capital from owned equipment | Asset Refinance / Sale & Leaseback | 5–10 Days | The asset itself |
| Raise larger sums on lower-cost terms | Commercial Mortgage / Property Charge | 3–6 Weeks | Property Security |
| Fund an urgent purchase before long-term debt | Commercial Bridging Finance | 5–14 Days | Property Security |
Indicative only. Speed, rates, and security depend on lender criteria, trading history, and overall asset quality.
1. Term Loans vs. Flexible Credit Lines
Unsecured Business Loans (typically £10,000 to £500,000+) provide a fixed lump sum repaid over 1 to 5 years. They are simple and predictable, but interest runs on the full balance from day one, and many require a Director Personal Guarantee (PG).
Flexible Credit Lines (often referred to as Revolving Credit Facilities or RCFs) operate like a modern business line of credit. You are approved for a limit, draw what you need, repay as customer cash arrives, and redraw throughout the facility term. Crucially, you pay interest only on what you have drawn, making them ideal for inventory management and short-term operational gaps.
What to compare beyond the headline rate:
- Arrangement, drawdown, and monthly facility fees.
- How interest is charged (monthly balance vs. fixed drawdown fee).
- Early repayment charges (some lenders charge zero penalty, others charge heavily).
- Personal guarantee terms and whether the guarantee is capped.
2. Invoice & Payroll Finance: Funding That Scales with Sales
For recruitment agencies, logistics firms, and B2B contractors, cash flow bottlenecks are rarely caused by a lack of sales—they stem from 30, 60, or 90-day payment terms.
- Factoring: Funds the ledger and includes credit control support.
- Confidential Invoice Discounting: Advances capital while leaving customer management entirely in your hands.
- Selective Invoice Finance: Allows you to fund specific high-value invoices as required.
Advances typically range from 80% to 90% of invoice values. Once the facility is live, funds can be drawn within 24 hours of issuing new invoices, creating a funding line that expands automatically as turnover grows.
3. Asset Finance: Letting Equipment Fund Itself
If you need vehicles, machinery, or technology, Asset Finance (Hire Purchase or Equipment Leasing) spreads the cost over time using the asset itself as primary security. This preserves your trading bank lines and unsecured borrowing capacity.
Businesses that already own plant, vehicles, or machinery outright can also utilise Asset Refinance to unlock cash for general working capital.
4. Property-Backed Funding: Lower-Cost Capital for Larger Sums
Unsecured lenders price heavily for risk. If your business owns its premises or holds commercial real estate with equity, securing debt against a property charge can unlock larger facilities over longer terms at often lower interest rates.
Commercial Mortgage LTV Benchmark Positions:
- Standard Owner-Occupier & Investment: Typically 65% to 75% LTV.
- Prime Covenants & Tier-1 Sectors: Up to 80% LTV available with select lenders.
- Sitting Tenant Acquisitions: Up to 90% LTV possible for established business tenants buying their own trading premises (e.g., pub tenant acquisitions).
Important: Property-backed borrowing puts your property at risk. Always ensure repayments remain sustainable before securing debt against real estate.
