UK Business Banking and Finance: The Complete Guide

Business current accounts

A business current account is the foundation of UK business banking. Limited companies, partnerships, and many sole traders separate business finances from personal finances through a dedicated account. Major banks, building societies, and challenger fintechs all offer business accounts, with differing fee structures (monthly fees, per-transaction fees, free banking periods for new customers).

FSCS protection for SMEs

SMEs with deposits in UK banks are eligible for FSCS protection of up to GBP 85,000 per banking licence, on similar terms to personal customers, provided the business meets certain size thresholds. Sole traders are protected on the same basis as individuals.

Credit cards and short-term credit

Business credit cards provide payment flexibility and a short interest-free period on purchases. Charge cards (where the balance must be paid in full each month) are common for larger spend. Business overdrafts and revolving credit facilities provide short-term liquidity but at higher rates than long-term loans.

Term loans

Term loans provide fixed amounts repaid over a set period, typically 1 to 10 years. Loans up to GBP 250,000 are typically unsecured for established businesses; larger loans usually require security (often a property charge or a personal guarantee from the directors).

Asset finance

Asset finance (hire purchase, leasing, finance leases) funds the acquisition of specific equipment, vehicles, or machinery, secured against the asset itself. Asset finance is widely used in transport, manufacturing, and construction. The Finance and Leasing Association publishes UK industry data.

Invoice finance

Invoice finance (factoring and invoice discounting) advances cash against unpaid customer invoices, typically 80 to 90 percent of invoice value. The business repays as customers settle. Factoring includes credit control by the finance provider; invoice discounting leaves credit control with the business.

Equity finance

Equity finance comes from founders, angel investors, venture capital firms, and private equity. The UK has well-developed equity markets at every stage: SEIS and EIS for early stage with tax-advantaged investor relief, VC for growth, AIM and the Main Market for public listing.

Government schemes

The British Business Bank operates several schemes accessible through accredited lenders: the Growth Guarantee Scheme (successor to the Recovery Loan Scheme), Start Up Loans (personal loans up to GBP 25,000 for new founders), and Enterprise Capital Funds (co-investment with private capital).

Bank Referral Scheme

Under the Small Business, Enterprise and Employment Act 2015, designated UK banks must refer SMEs they reject for finance to designated alternative finance platforms. The scheme aims to reduce the proportion of unmet SME finance demand.

Open Banking

The Open Banking framework, implemented under the Competition and Markets Authority order and EU PSD2, allows third-party providers (with the customer's consent) to access bank account data and initiate payments. UK fintech has built a range of business cash management, accounting, and lending services on this infrastructure.

UK business finance and the British Business Bank

The British Business Bank is a state-owned economic development bank founded in 2014 to support UK SME finance. The bank does not lend directly to businesses but operates through accredited commercial lenders. Programmes include the Growth Guarantee Scheme (the current successor to the Recovery Loan Scheme), the Start Up Loans scheme (personal loans up to GBP 25,000 to new founders), Enterprise Capital Funds (co-investment with private capital), and the Regional Angels Programme.

The Bank Referral Scheme, operational since November 2016 under the Small Business, Enterprise and Employment Act 2015, requires the nine largest UK SME-lending banks to refer SME finance applications they reject to designated alternative finance platforms with the applicant's consent. The scheme aims to reduce unmet SME finance demand.

The British Business Bank publishes annual statistics on UK SME finance markets in the Small Business Finance Markets report at british-business-bank.co.uk. The report provides comprehensive data on lending volumes, equity investment, and finance gaps by region and sector. Recent reports have noted the growth of fintech and challenger bank lending alongside the continued dominance of the major incumbent banks.

Sole trader, partnership, and limited company structures

UK businesses operate under several legal structures with different tax and reporting implications. Sole traders report business profits through the self-employment pages of Self Assessment, paying income tax and Class 2 (voluntary from April 2024) and Class 4 NICs on profits above the relevant thresholds. There is no legal separation between the business and the individual; the sole trader is personally liable for business debts.

Partnerships operate similarly with partners sharing profits according to the partnership agreement. Limited liability partnerships (LLPs) under the Limited Liability Partnerships Act 2000 provide limited liability protection while retaining partnership tax treatment. General partnerships under the Partnership Act 1890 do not provide liability protection.

Limited companies under the Companies Act 2006 provide full liability protection, separate legal personality, and access to corporation tax rates. Companies pay corporation tax on profits (19 percent up to GBP 50,000 of profits, marginal relief between GBP 50,000 and GBP 250,000, and 25 percent above GBP 250,000 from April 2023). Profits extracted as dividends are taxed at 8.75, 33.75, or 39.35 percent above the GBP 500 dividend allowance; salary is taxed as employment income with NI.

VAT registration and Making Tax Digital

VAT registration is compulsory where taxable turnover exceeds the registration threshold of GBP 90,000 over a rolling 12 month period from 1 April 2024. Voluntary registration is available below the threshold and can be beneficial where the business's customers are VAT-registered (allowing them to reclaim input VAT) or where input VAT recovery exceeds output VAT.

Standard VAT is 20 percent on most goods and services; reduced rates of 5 percent (energy, certain construction) and 0 percent (food, children's clothes, books) apply to specific categories. Some supplies are exempt (financial services, insurance, education) and some are outside the scope. The VAT return is filed quarterly under Making Tax Digital rules, which require digital record-keeping and software-based submission.

The VAT Flat Rate Scheme allows small businesses to pay a single percentage of turnover as VAT instead of calculating input and output VAT separately. The scheme is available to businesses with VAT-exclusive turnover below GBP 150,000. Different sector rates apply; the scheme often produces a small VAT saving for service businesses with low input VAT.

Companies House and corporate reporting

Limited companies must file annual accounts and confirmation statements with Companies House. Small company accounts under the Companies Act 2006 require a balance sheet and limited disclosures; micro-entity accounts under the FRS 105 framework allow even simpler reporting. Audit is required for companies above the small company audit threshold (turnover above GBP 10.2 million or balance sheet above GBP 5.1 million in two of the last three years).

The Economic Crime and Corporate Transparency Act 2023 introduced significant changes to Companies House powers and reporting requirements. Identity verification for directors and persons with significant control (PSCs) is being phased in; the Registrar of Companies has expanded powers to query and reject filings that appear incorrect.

The Persons with Significant Control register identifies beneficial owners holding more than 25 percent of shares or voting rights. The register is publicly available, providing transparency about ultimate ownership. Trust structures used to hold UK company shares are subject to the Trust Registration Service requirements.

Employer obligations and PAYE

Employers must operate PAYE for employee salaries, deducting income tax and National Insurance contributions and remitting them to HMRC through the Real Time Information system. Employer NICs (15 percent from April 2025 on earnings above the secondary threshold) and the apprenticeship levy (0.5 percent of pay bill above GBP 3 million) apply to medium and large employers.

Auto-enrolment under the Pensions Act 2008 requires employers to enrol eligible workers into a qualifying workplace pension and make minimum employer contributions of 3 percent of qualifying earnings (with total contributions of at least 8 percent). The Pensions Regulator enforces compliance with penalties for failure to enrol or contribute correctly.

Cash flow and working capital management

Cash flow management is the most common cause of UK SME failure. The Federation of Small Businesses (FSB) and successive government studies have documented the impact of late payment, the importance of working capital facilities, and the value of cash flow forecasting. The Prompt Payment Code, voluntary but signed by many large UK businesses, sets a 30 to 60 day payment standard for supplier invoices.

Working capital facilities (overdrafts, revolving credit, invoice finance) bridge the gap between paying suppliers and receiving customer payments. Typical working capital requirements run 30 to 90 days of operating expenses, depending on the business model. Service businesses with regular monthly billing typically need less working capital than businesses with long manufacturing or delivery lead times.

Accounting and bookkeeping requirements

UK businesses must keep adequate records to support their tax returns. Sole traders and partnerships keep records for at least 5 years after the relevant Self Assessment filing deadline. Limited companies keep records for at least 6 years after the relevant accounting period end. The records must include all income, expenses, assets, liabilities, and (where applicable) VAT.

Making Tax Digital (MTD) requires VAT-registered businesses to keep digital records and submit returns through MTD-compatible software. MTD for Income Tax Self Assessment is being phased in for sole traders and landlords with income above specified thresholds. The current government timetable extends MTD for ITSA from April 2026 for the highest income tier; phased introduction below this threshold continues.

The corporate insolvency framework

UK corporate insolvency law operates under the Insolvency Act 1986 (as amended) and the Corporate Insolvency and Governance Act 2020. Options for distressed businesses include the Company Voluntary Arrangement (CVA), administration, the new Restructuring Plan under Part 26A of the Companies Act 2006, and liquidation. Each has different consequences for creditors, directors, and ongoing operations.

The Insolvency Service oversees insolvency practitioners and operates the Bankruptcy and Companies Court. Directors of insolvent companies face potential personal liability under wrongful trading provisions if they continue to trade while knowing insolvency is unavoidable. Professional advice from a licensed insolvency practitioner is essential at the earliest sign of distress.
