A business plan template uk business owners can actually use should give you a downloadable structure and explain what goes in each section, which is exactly what company incorporation customers ask us for before they file. Grab the template below, then work through it section by section. A UK business plan should cover what the business does, who it sells to, how it makes money, and what the numbers look like over the next one to three years. Lenders and investors read the financial forecast first, so that section carries the most weight. You don’t need a business plan to register a limited company with Companies House, but most banks will ask for one when you open a business account.

Download the UK business plan template

This free business plan template comes with no form to fill in first. Download it, then use the rest of this page as the instruction manual for each section. It’s built for a UK limited company, so it prompts you for the things a generic or US template skips. That includes your sole trader or limited company decision and your VAT position.

What should a UK business plan contain?

Most working plans run to eight sections. Each one answers a question a reader will otherwise ask you directly.

Executive summary: what the business is, in one page.
The business: what you sell and why it exists.
Market: who buys and how big the opportunity is.
Competitors: who else does this and how you differ.
Operations: how the thing actually gets delivered.
Team: who runs it and what they’ve done before.
Financial forecasts: the numbers over one to three years.
Funding requirement: how much you need and what for.

A good small business plan template keeps these in order but lets you write them out of order. The summary comes first on the page and last on your to-do list.

How do you write the executive summary?

Write it last, even though it sits first. It’s a summary of decisions you haven’t made yet at the start. Keep it to a page. A lender skims it to decide whether to read on, so lead with what you do, who pays, and how much you’re asking for. This is the part of how to write a business plan uk readers most often get wrong: they draft the summary first and then spend weeks rewriting it. Draft the body, then distil it.

How do you describe the business and the market?

The business section states what you sell and the problem it removes. Be concrete: name the product, the price point, and the customer. The market section sizes the opportunity and names your buyer. A uk business plan example that says “everyone needs this” reads as a red flag; a specific buyer reads as a plan.

Why does the financial forecast get read first?

Because it’s where optimism meets arithmetic. A lender or investor turns to the forecast before the prose, so it has to hold up on its own. You’ll typically include three things: a sales forecast, a profit and loss projection, and a cash flow forecast. Cover one to three years, monthly for year one.

Sales forecast: units, price, and the assumptions behind both.
Profit and loss: revenue less costs, showing the margin.
Cash flow: when money actually lands and leaves.

The method behind these numbers is its own discipline. We cover it in depth in our guide to financial forecasting, so this section stays on what a plan needs rather than how to model it. If the numbers are where you stall, this is the part Sleek’s accounting service is built to help with. Our accountants build the forecast, an AI does the heavy lifting on the workings, and you see every step in the audit trail.

Which structure should you choose before writing the plan?

Your structure shapes the numbers, so decide it first. A limited company and a sole trader are taxed differently and read differently to a lender. Most business owners writing a full plan are heading for a limited company, which is what this template assumes. If you’re weighing it up, our guide to what a limited company costs to run lays out the ongoing commitment. Once you’ve decided, registering your company is a same-week job, and your plan can name the entity from the start.

What UK-specific things does a generic template miss?

Off-the-shelf templates are usually American. They skip the three things a UK reader needs to see.

Company structure: your limited-company decision, stated up front.
VAT: you must register once taxable turnover passes £90,000, and many plans note when they expect to cross it. You can check the detail in our the VAT threshold guide.
Companies House: incorporation is a live cost. The digital registration fee rose to £100 on 1 February 2026.

There’s a banking point too. Most lenders expect a plan before opening a business bank account, so the plan and the account tend to happen together.

Why do business plans get rejected?

Rarely for the idea. Usually for the numbers or the gaps around them.

Forecasts with no stated assumptions behind them.
A market defined as “everyone” rather than a named buyer.
No funding figure, or a figure with no use attached.
Costs that ignore VAT, tax, or the cost of running the company.

Fix the numbers and most rejections disappear. That’s the section worth a second pair of eyes.

What does Sleek help with, and what does it not?

To be plain about it: Sleek doesn’t write your business plan. The story, the market, the vision are yours. What we help with is the financial section, the forecast and the numbers a lender scrutinises, plus the incorporation and accounting that follow. A qualified accountant reviews the figures, and you see exactly what was done.

FAQs on business plan template

Do I need a business plan to register a limited company?

No. Companies House doesn’t ask for a business plan to incorporate. You’ll want one anyway for a bank account or funding, and the UK resources hub has the surrounding guides.

How long should a UK business plan be?

Most sit between 15 and 25 pages, plus the financial appendix. A lender wants enough to trust the numbers and not a word more.

Do banks still ask for a business plan?

Yes. Most UK banks ask for one when you open a business account, and it’s the most common reason business owners write a plan at all.

What financial forecasts should I include?

A sales forecast, a profit and loss projection, and a cash flow forecast, covering one to three years. Show year one monthly so the cash position is clear.

Do I need a business plan to open a business bank account?

Usually, yes. Most providers ask for a plan or a summary of it, which is why the plan and the account tend to get done in the same week.

Should I write the plan before or after I incorporate?

Either works, but most business owners draft the plan first and incorporate once the structure is settled. The plan can then name the registered company from page one.

Can I use a US business plan template in the UK?

You can start from one, but it will miss VAT, Companies House, and UK company structure. A UK template prompts you for those, which is why this one exists.
