How to fund business growth without giving up equity in the UK
Rook Bristol Editorial · Updated · 8 min read
The short answer
UK business owners can fund growth without giving up equity by using debt and other non-dilutive options: business loans, revolving credit, revenue-based finance, asset finance, invoice finance, retained profit and grants. You repay the funding rather than selling shares, so you keep full ownership and future profits. The best fit depends on what you are funding and how predictable your revenue is.
Equity investment gets the headlines, but most UK small businesses grow on retained profit and borrowing. Selling a share of your company is permanent. A loan ends when it is repaid.
That does not make debt right for everyone. This guide explains the options, what they really cost compared with equity, and how to tell whether your business can comfortably take them on.
Key takeaways: non-dilutive finance lets you grow while keeping 100% of your shares and future profit; the right product depends on what you are funding, from one-off projects to equipment or slow-paying invoices; debt must be repaid whatever happens, so affordability matters more than headline cost; equity can still be the better choice for early-stage, high-risk or pre-revenue businesses.
What does funding growth without giving up equity mean?
It means raising money you repay, rather than money you get in exchange for a share of ownership.
Equity is ownership of a company, usually held as shares. When you sell equity to an investor, they own part of the business permanently, share in its profits and usually gain some say in decisions. Funding that does not require you to give up shares is called non-dilutive, because it does not dilute, or shrink, your percentage of ownership.
Non-dilutive options for UK SMEs include:
- Retained profit: reinvesting what the business already earns.
- Business loans: a lump sum repaid in fixed instalments over an agreed term.
- Revolving credit: a limit you can draw from, repay and draw again.
- Revenue-based finance: funding repaid as a share of your future revenue, so repayments flex with sales.
- Asset finance: spreading the cost of vehicles, machinery or equipment, with the asset supporting the finance.
- Invoice finance: releasing cash tied up in unpaid customer invoices.
- Grants and government-backed schemes: such as Innovate UK competitions, or lending supported by the British Business Bank through accredited lenders.
What is the difference between debt and equity finance?
Debt is repaid with interest over a set period and then ends, while equity is never repaid but permanently gives an investor a share of the business.
| Debt finance | Equity finance | |
|---|---|---|
| Ownership | You keep 100% | Investor owns a share |
| Repayment | Fixed or flexible repayments until cleared | No repayment, investor gains from growth or sale |
| Cost | Interest and fees, known in advance | A share of all future profit and sale value |
| Control | Lender has no say in running the business | Investors may take board seats or veto rights |
| Duration | Ends when repaid | Permanent unless shares are bought back |
| Risk to you | Repayments due even in a bad month; may need a personal guarantee | Investor shares the downside |
| Tax | Interest is usually a deductible business cost | Dividends are paid from post-tax profit |
On tax, the general principle is that loan interest is a business expense for corporation tax purposes, but how it applies to you depends on your circumstances. Check HMRC guidance on GOV.UK or ask your accountant.
How much does equity really cost compared with a loan?
Equity has no monthly repayment, but if the business grows, it is often far more expensive than borrowing.
The cost of a loan is visible up front: the total amount repayable minus what you borrowed. The cost of equity only becomes clear later, when profits are shared or the business is sold. Here is a simple comparison. All figures are illustrative and are not a quote or a prediction.
| Sell 20% equity | Take a loan | |
|---|---|---|
| Money raised | £200,000 | £200,000 |
| Assumed cost of loan interest and fees (illustrative) | None | £50,000 over the term |
| Company value five years later (illustrative) | £2,000,000 | £2,000,000 |
| Value of the stake you gave away | £400,000 | £0 |
| Share of annual profit given away (if profit is £300,000) | £60,000 every year | £0 |
| Total cost to you | £400,000 of value, plus 20% of future profit | £50,000, then it ends |
The flip side is risk. If growth stalls, the equity investor shares the loss, while the loan still has to be repaid in full. That trade-off is the real decision: lower long-term cost and full control, in exchange for a fixed obligation.
To compare loan costs properly, look at the total amount repayable, not just the monthly figure. Our guide on how to read a business finance offer explains what to compare line by line.
Which type of finance fits what I'm funding?
Match the structure of the finance to the thing you are paying for and how quickly it will pay you back.
| What you are funding | Often a good fit | Why |
|---|---|---|
| A one-off project, fit-out or expansion | Business loan | Fixed amount, fixed repayments, a clear end date |
| Ongoing working capital and timing gaps | Revolving credit | Draw and repay as needed, pay only on what you use |
| Marketing or stock for a growing online business | Revenue-based finance | Repayments rise and fall with sales |
| Vehicles, machinery or equipment | Asset finance | Spreads the cost over the asset's working life |
| Bigger orders from slow-paying customers | Invoice finance | Unlocks cash already earned but not yet paid |
Retained profit deserves a mention too. It is the cheapest source of growth funding because there is no interest and no dilution, but it is also the slowest. Many owners combine the two: they fund part of an investment from reserves and borrow the rest, which keeps repayments lower and leaves a cash buffer in the bank.
Grants are another non-dilutive route, but they are usually competitive, tied to specific activities such as research or decarbonisation, and can take months to award. They are rarely a fit for time-sensitive growth. Research and development tax relief, administered by HMRC, can also return cash to eligible companies after the spending has happened. Check the current rules on GOV.UK, as the schemes have changed in recent years.
A common mistake is using short-term money for long-term assets, or the reverse. If a new machine will earn its keep over five years, spreading its cost over a similar period usually makes more sense than squeezing it into twelve months.
How much can my business afford to borrow for growth?
A useful rule of thumb is that your business should generate comfortably more cash than it needs for all its debt repayments, even in a weaker month.
Lenders often measure this with the debt service coverage ratio, or DSCR. It divides the cash your business generates from operations by its total debt repayments over the same period. A DSCR of 1.0 means every pound of cash goes on repayments, leaving nothing spare. Lenders generally want to see a healthy margin above that.
For example, and purely as an illustration: if your business generates £15,000 a month of operating cash and existing repayments are £4,000, a new £3,000 monthly repayment would take total repayments to £7,000. Your DSCR would fall from 3.75 to about 2.14. That still leaves room, but you can see how quickly headroom shrinks. Try your own figures in the DSCR calculator.
Ask yourself honestly: will the growth this money funds pay for itself within the term? And what happens to repayments if sales dip for a quarter?
Do I need a personal guarantee to borrow without giving up equity?
For unsecured business lending in the UK, directors are often asked for a personal guarantee, so it is worth understanding before you apply.
A personal guarantee is a promise by a director or owner to repay the business debt personally if the business cannot. It is how many lenders offer finance without taking security over specific business assets. It means you keep your shares, but you take on personal responsibility for the borrowing.
Read the terms carefully, understand whether the guarantee is capped, and take independent legal advice before signing. Personal guarantees explained sets out what directors are actually agreeing to.
When does equity make more sense than debt?
Equity can be the better choice when a business has little or no revenue, very uncertain returns, or needs expertise as much as cash.
Borrowing works best when there is steady revenue to support repayments. A pre-revenue technology start-up, or a business pursuing a long, high-risk project, may struggle to meet fixed repayments and may benefit from investors who share the risk and bring contacts or experience.
Many owners use both over time: equity in the earliest stage, then debt once revenue is established, so later growth does not dilute them further. The British Business Bank publishes impartial guidance on the different types of finance available to smaller businesses, which is a good place to compare options. This article is general information, not personal financial advice, so speak to your accountant or an adviser about your own situation.
How do I prepare to fund growth with debt?
Get clear on the numbers, the plan and your existing commitments before you speak to a lender.
- Write down exactly what the money is for and how it will generate a return.
- Estimate how long the investment takes to pay back, and choose a term that matches.
- Build a simple cash flow forecast showing the new repayment alongside existing costs.
- List every existing loan, card, overdraft and advance, with monthly repayments.
- Check your Companies House filings and HMRC payments are up to date.
- Gather three to six months of business bank statements. What lenders look for in your bank statements explains what they will check.
- Decide how much you want to borrow and the most you are comfortable repaying each month.
Preparing this way makes you a stronger applicant and, just as importantly, tells you whether borrowing is the right move at all.
