How to Write a Business Plan That Banks and Investors Accept

If you’re seeking funding in the UK — whether through a bank loan, private investor, or government scheme — your business plan will be the first thing decision-makers review.

A weak or generic plan often leads to rejection. A strong, well-structured business plan backed by solid financial projections significantly increases your chances of approval.

At TT Accountancy Services (TTAS), we help UK startups and SMEs prepare professional business plans that meet the expectations of banks and investors. In this guide, we explain how to write a business plan that gets taken seriously — and funded.


Why Banks and Investors Reject Business Plans

Before writing your plan, understand why many fail:

  • Unrealistic financial forecasts
  • No clear revenue model
  • Poor cash flow projections
  • Weak market research
  • Lack of risk assessment
  • Inconsistent or missing financial data

Lenders and investors want clarity, realism, and evidence — not just ambition.


1. Start With a Clear Executive Summary

Your executive summary is the most important section. Many decision-makers read only this before deciding whether to continue.

Include:

  • Business name and structure
  • What your business does
  • Target market
  • Funding required
  • How funds will be used
  • Summary of projected profitability

Keep it concise but compelling.


2. Define Your Business Model Clearly

Explain:

  • What you sell
  • Who your customers are
  • How you make money
  • Your pricing structure
  • What makes you different

Avoid vague statements. Be specific and data-driven.


3. Provide Detailed Market Research

Banks and investors expect proof that demand exists.

Include:

  • Industry overview
  • Target audience analysis
  • Competitor comparison
  • Market trends
  • Location advantages (especially for London businesses)

Demonstrate that your idea is viable and scalable.


4. Include Strong Financial Forecasts

This is where many business plans fail.

Your financial section should include:

  • 12–36 month profit and loss forecast
  • Cash flow forecast
  • Balance sheet projection
  • Break-even analysis
  • Startup costs breakdown

Lenders want to know:
✔ Can you repay the loan?
✔ When will the business become profitable?
✔ What happens if revenue is lower than expected?

Professional accounting input makes this section far more credible.


5. Show How Much Funding You Need — and Why

Be precise about:

  • Total funding required
  • How funds will be allocated
  • Expected return on investment
  • Repayment plan (if applying for a loan)

Avoid round figures without explanation.


6. Address Risks and Mitigation Strategies

No business is risk-free. A realistic risk assessment builds trust.

Examples of risks:

  • Market competition
  • Rising operating costs
  • Cash flow delays
  • Regulatory changes
  • Economic uncertainty

Then explain how you will manage those risks.


7. Demonstrate Management Capability

Investors invest in people as much as ideas.

Highlight:

  • Founder experience
  • Relevant qualifications
  • Key team members
  • Advisors or accountants supporting the business

A strong support network increases credibility.


8. Align With UK Compliance Requirements

Your business plan should reflect awareness of:

  • Corporation Tax obligations
  • VAT registration thresholds
  • Payroll responsibilities (if hiring staff)
  • Companies House requirements

Demonstrating compliance knowledge reassures lenders that you understand operating responsibilities.


9. Keep the Plan Professional and Structured

A strong business plan should be:

✔ Clear and easy to read
✔ Professionally formatted
✔ Free from spelling or calculation errors
✔ Backed by realistic assumptions

Presentation matters — especially when dealing with banks.

  • Private lenders

Each funding source has slightly different expectations — professional preparation increases your success rate.


A strong business plan is more than a document — it’s a roadmap for your business and a signal to lenders that you are serious, prepared, and financially aware.

If you want banks and investors to say “yes,” your plan must show:

✔ Clear strategy
✔ Strong financial projections
✔ Realistic assumptions
✔ Risk awareness
✔ Professional presentation
