Business Plan UK: How to Write a Plan British Lenders and Investors Will Fund

A business plan UK lenders take seriously is shorter, more numbers-led and more honest about risk than most first-time founders expect. British banks have read thousands of plans. They skim the story and go straight to the cash flow.

This guide covers what UK lenders and investors look for, which structure to choose, the tax points your forecast has to reflect and where public funding fits. If paperwork makes you uneasy, that’s normal. Most of it is simpler than it looks once you see what each reader actually checks.

What a business plan UK lenders accept needs to show

UK high street banks, the Start Up Loans scheme and angel investors all ask the same three questions. Can this person run this business? Is there real demand? Will the cash last until the business pays for itself?

Your plan answers those with evidence, not adjectives. A café owner in Leeds who shows three competitor price lists, footfall counts from two mornings and a supplier quote is far more convincing than one who writes “strong local demand”.

The sections a UK reader expects

• Executive summary: one page, written last, with the amount you need and what it buys.
• The business and the founder: what you sell, to whom, and why you can deliver it.
• Market and competitors: named local rivals, their prices and your gap.
• Marketing and sales: how the first 100 customers find you, with costs.
• Operations: premises, suppliers, staff, licences and insurance.
• Financials: a 12-month cash flow forecast, profit and loss and a simple balance sheet, with your assumptions written out.

Our guide to writing a business plan walks through each section in order, and the business plan template gives you the headings ready to fill.

Start Up Loans: what the business plan UK scheme asks for

The government-backed Start Up Loans scheme lends up to £25,000 per founder at a fixed 7.5% a year, over one to five years, with 12 months of free mentoring. It’s a personal loan used for business purposes, so your own credit history matters.

The British Business Bank guidance confirms you’ll need a business plan and a cash flow forecast as part of the application. Assessors look hard at the forecast. If your month-three sales jump from £2,000 to £9,000 with no reason given, expect questions.

Choosing your structure: sole trader, partnership or Ltd

Your structure changes the numbers in your plan, so decide it early. Most UK start-ups pick one of three.

Structure	Liability	How profit is taxed	Best for
Sole trader	Unlimited, you are the business	Income tax and National Insurance on profits	Low-risk service businesses, side projects, testing an idea
Partnership	Partners share unlimited liability (unless an LLP)	Each partner pays income tax on their share	Two or more people starting together on a small scale
Private limited company (Ltd)	Limited to what you invest	Corporation tax on company profits, then tax on salary or dividends	Businesses taking on debt, staff, premises or outside investors

A limited company is registered with Companies House, which keeps a public record of directors, shareholders and annual accounts. Investors will almost always want an Ltd, because they can buy shares in it. Sole traders register with HMRC for Self Assessment instead.

Put this sequence, with dates, in the operations section of your plan. It shows the reader you know what has to happen before the doors open.

Tax points your forecast must reflect

Getting tax wrong is the most common error we see in UK forecasts. Three items matter most.

VAT

The standard VAT rate is 20%, with a reduced 5% rate on a short list of goods and services. You must register once taxable turnover passes £90,000 in a rolling 12 months. If you sell to consumers, crossing that line can cut your margin by a sixth overnight unless you raise prices, so show in the plan when you expect to hit it.

Corporation tax

Limited companies pay corporation tax at 25% on profits above £250,000 and 19% on profits of £50,000 or less, with marginal relief in between. Most start-ups sit in the 19% band for their first years. Your profit and loss should show tax as a cost line, not leave it out.

Employment costs

If you plan to hire, budget for employer National Insurance and workplace pension contributions on top of gross pay. A £26,000 salary costs you noticeably more than £26,000, and lenders check that you’ve allowed for it.

Funding routes beyond the bank

The Start Up Loans scheme is the best-known public option, but it isn’t the only one. The British Business Bank also backs regional funds and guarantee schemes that sit behind loans from commercial lenders. In practice, you apply through the lender, and they decide whether to use the guarantee.

Equity investors are the other route. Angel investors in London, Manchester and Edinburgh often ask whether you qualify for SEIS or EIS tax relief, because it reduces their risk. If you’re raising equity, say in your plan whether you’ve applied for advance assurance from HMRC. It isn’t a guarantee, but it shows investors you’ve done the homework.

What investors add to the checklist

Banks want to know you can repay. Investors want to know you can grow. So an investor-facing plan needs three extra things: the size of the market you can realistically reach, how you’ll use their money milestone by milestone, and how they might eventually get it back. A sale to a larger competitor in five years is a perfectly good answer, as long as you can name who might buy.

They’ll also want a cap table showing who owns what today and after the round. Keep it to one simple table.

Grants exist but are narrow, usually tied to innovation, a region or a sector. Don’t build your plan around one you haven’t been awarded yet.

Local costs and how they change your numbers

London rents, rates and wages sit well above the rest of the country, and a plan for Shoreditch shouldn’t use Sheffield numbers. Business rates also vary by property. In England, small business rate relief removes them entirely for a single property with a rateable value of £12,000 or less. Scotland, Wales and Northern Ireland run their own schemes, so check with your council before you fix a figure.

The fix is simple: get two or three real quotes for premises, insurance and key equipment in your actual town, and put them in an appendix. A lender trusts a quote more than an estimate.

Why a business plan UK banks reject usually fails

Rejections rarely come down to the idea. They come down to the maths and the missing detail. These are the five problems we see most often:

1. Sales start too fast. A new salon at 80% capacity in month one isn’t believable. Ramp up over six to twelve months.
2. No owner’s drawings. If you’re leaving a job, you need to live. Put a realistic personal draw in the cash flow.
3. Tax left out. VAT, corporation tax and employer costs all reduce the cash you actually keep.
4. No contingency. Fit-outs overrun. A 10% buffer on start-up costs looks sensible, not weak.
5. Assumptions hidden. If the reader can’t see where a number came from, they assume it was guessed.

Fix those five and your plan is already ahead of most that land on a lender’s desk.

Language and presentation

English is the only language you need. Keep it plain and use pounds throughout, with VAT shown clearly as included or excluded. A business plan UK readers enjoy is 15 to 25 pages plus appendices, with the forecast in a spreadsheet they can open and test.

Writing a business plan UK cities expect

Local detail wins trust. A plan for Glasgow should mention Glasgow competitors and Glasgow rents, not national averages. We’ve written city guides with local market notes for the main UK cities:

• London, Manchester, Birmingham and Leeds
• Glasgow, Edinburgh, Bristol and Liverpool
• Cardiff, Belfast, Sheffield and Newcastle

Moving to the UK to start a business

If you’re coming from abroad, your plan does a second job: it supports a visa application. The Innovator Founder route needs an endorsement from an approved body, and the plan is central to that. Our Innovator Founder visa business plan guide covers what endorsing bodies look for, and the visa business plan hub compares routes in other countries.

Sample business plans you can adapt

Each of these is written for a real UK city, in pounds, with a full financial section you can rework for your own figures:

• Coffee shop business plan (Manchester)
• Barbershop business plan (London)
• Cleaning business plan (Leeds)
• Bakery business plan (Bristol)
• Home care business plan (Liverpool)
• Airbnb business plan (Edinburgh)
