High street banks are approving more term loans and overdrafts, although totals remain below pre‑pandemic peaks. Challenger banks and fintechs provide most new lending volume. For pure speed, consider online term loans, revolving credit, or merchant cash advances. For bigger ticket assets, look at asset finance, while recurring cash flow gaps often suit invoice finance. If security or pricing is a concern, check lenders accredited under the Growth Guarantee Scheme. Exporters should also look at UK Export Finance.

With lending to smaller businesses recovering through 2024, funding routes have never been more diverse in 2025. This guide compares high street banks with leading fintechs and shows where each option fits by cost, speed, and eligibility.

The top 10 funding options in 2025

1) High street bank term loans and overdrafts

Core options for established SMEs. You will apply via relationship teams at banks like Lloyds Bank or Barclays. Expect stronger affordability tests, with pricing that can be attractive if you meet criteria. Useful for expansion, acquisitions, capex, or cash flow smoothing via overdraft.

2) Online term loans, eg Funding Circle

Fast, unsecured loans decided via online applications and bank‑data checks. Funding Circle lists starting rates in its help content and supports early repayment with no fee, which suits seasonal cash flow or projects where you expect to repay quickly.

3) Revolving credit facilities and flexible lines, eg iwoca

Great for short‑term working capital. Providers like iwoca offer limits that you draw and repay as needed. Interest is charged only on the amount and days used. Handy for stock purchases or bridging VAT.

4) Merchant cash advance, eg Capify

Repayments flex with your card takings, which helps if revenue is variable. Providers such as Capify collect a fixed percentage of daily card sales until the agreed amount is repaid. Costs are usually higher than bank loans, so match this to short‑term needs and strong card turnover.

5) Asset finance, hire purchase, and leasing

Use specialist lenders for vehicles, plant, and equipment. Asset finance can fund a large portion of UK investment in machinery and vehicles each year, with substantial volumes flowing to SMEs. Consider reputable providers or brokers, and compare total cost of ownership, balloon payments, and end‑of‑term options.

6) Invoice finance and asset‑based lending

Advance a percentage of your unpaid invoices to smooth cash flow or fund growth tied to receivables. Options include invoice discounting, factoring, and full ABL structures with inventory and plant. Fit for B2B firms with predictable debtor books.

7) Government‑backed Growth Guarantee Scheme

The Growth Guarantee Scheme helps lenders offer better terms to eligible SMEs. Facilities are delivered by accredited banks and specialist lenders. Use this route if pricing or security is a blocker with a standard facility.

8) Export finance and insurance, via UKEF

UK Export Finance can guarantee working capital and provide insurance for export contracts, improving access to bank funding and de‑risking new markets. Useful for firms scaling internationally.

9) Equity finance, SEIS/EIS, and venture

For high‑growth firms, equity can be preferable to debt. Activity improved in 2024, with investment picking up from 2023 levels. Explore angel networks, SEIS or EIS funds, and regional co‑investment programmes. Equity is slower to close than debt and dilutes ownership, so plan ahead.

10) Regional and specialist lenders

Challenger banks and regional funds have been growing share of SME lending. Look at newer banks and specialist lenders focused on particular sectors or regions when mainstream routes do not fit. You may find faster decisions and a higher risk appetite than the big five banks.

How to choose the right option in four steps

  1. Define the job to be done. Working capital, asset purchase, project, or export. The use case drives the product.
  2. Map affordability and security. Decide on monthly capacity and whether security or a personal guarantee is acceptable.
  3. Match time to cash. If speed matters, shortlist online term loans, revolving credit, or MCAs. For large assets, prioritise asset finance.
  4. Compare three offers. Request heads of terms that state APR or total cost, fees, term, security, early‑repayment rules, and covenants.

FAQs

  • What rates should I expect in 2025?
  • Pricing varies by risk, security, and product. Banks can be cheaper for strong cases. Online loans and merchant cash advances trade higher cost for speed and flexibility. Always compare total cost, not just rate, and check early repayment rules.
  • How fast can I get funds?
  • Online loans, flexible credit, and merchant cash advances can fund in one to five days for smaller amounts, assuming documents are ready. Bank facilities and asset finance usually take longer due to underwriting and security.
  • Does being a homeowner help?
  • It can improve options where lenders require personal guarantees or additional comfort, but many products are available without property security.
  • When should I use invoice finance over a loan?
  • Choose invoice finance if cash is tied up in receivables and you want a facility that grows with sales. Choose a loan if you have a discrete project with a clear payback.
  • What documents should I prepare?
  • Latest filed accounts, recent management accounts, six months of bank statements, aged debtor and creditor lists if relevant, key contracts or order book, and director ID. Having these ready speeds up decisions.
