Start a business or buy one? The honest arithmetic

This is a comparison written by a business-for-sale marketplace, so read it with that in mind. We have tried to be straight about the cases where starting something is clearly the better answer, because there are several and they are not rare.

What the data says

Of UK businesses born in 2019, 38.4 per cent were still trading five years later. Regionally that ranged from 43.5 per cent in the South West to 30.6 per cent in the West Midlands.

In 2024 there were 317,000 UK business births and 280,000 deaths. The register itself tells a similar story from a different angle: Companies House recorded 801,864 incorporations in the 2024 to 2025 financial year and 726,735 dissolutions, the highest number of dissolutions on record.

The honest interpretation: most new businesses do not reach five years, and a business that has already been trading for eight has passed the filter. That is a real advantage and it is not the same as a guarantee.

The comparison

| | Starting | Buying | | --- | --- | --- | | Capital on day one | Low | Substantial | | Revenue on day one | None | Established | | Customers on day one | None | Existing | | Time to a salary | Often years | Often immediate | | Main risk | Nobody wants it | You overpaid or missed something | | What you control | Everything | What you inherit | | Funding available | Limited | Lending against the business | | Failure cost | Time and modest capital | Capital, often secured | | Best case ceiling | Unlimited | Constrained by what you bought |

The case for starting

It costs very little to try. Company formation is inexpensive and same-day. A sole trader registration costs nothing. If the idea does not work, you have lost time and a modest amount of money rather than a secured loan.

You are not inheriting anybody's decisions. No legacy customers on bad terms, no staff hired by somebody else, no lease signed in better times, no systems chosen in 2014. Every constraint in an established business was a reasonable decision once and several of them are now problems.

The ceiling is higher. A business built around something genuinely new is not limited by what it was bought for. The businesses worth the most were all started.

Some things cannot be bought. If your idea does not exist yet, there is nothing to acquire. This is obvious and it is also the single most common reason starting is the right answer.

You may not need much. Service businesses, consultancies and most online businesses can be started alongside employment, tested cheaply, and scaled only if they work. That optionality has real value and buying does not offer it.

The case for buying

Revenue on day one. The gap between starting and profitability is where most new businesses fail, and buying removes it. You are paying to skip the period that the survival statistics measure.

Somebody has already proved the demand. The largest risk in a new business, whether anybody will pay for this, has been answered by people who have paid for it.

You can borrow against it. A lender will advance against an established business with a trading record. They will generally not lend against an idea. That changes what scale you can start at.

Staff, systems and suppliers exist. Along with the knowledge of how the work actually gets done, most of which is in people's heads rather than in any document.

Demographics. There were 5.7 million private sector businesses in the UK at the start of 2025, and a significant number are owned by people approaching retirement. Many of those businesses are profitable, unglamorous and will either be sold or will close. That is the supply side of this market and it is substantial.

The case against buying, which gets less attention

You commit capital before you know. Due diligence reduces uncertainty, it does not remove it. You will find something in the first year that nobody disclosed, because nobody knew.

You may be buying a job. A great many small businesses on the market depend entirely on their owner. Buy one of those and you have bought employment with a large entry fee and no notice period.

The price reflects the past. You pay a multiple of what it earned. If the reason it is for sale is that the earnings are about to change, and the seller saw it coming, you are paying for history.

Change is harder than it looks. Staff who have worked a particular way for eleven years, under an owner they liked, do not adopt a new owner's ideas in month two. TUPE means they arrive on their existing terms and with their existing expectations.

The work is finding it. Most buyers spend far longer searching than they expect. The businesses worth buying are not always the ones being marketed loudly.

Which suits which person

Starting suits you if you have an idea that does not exist, you can fund yourself while it develops, you would rather build than manage, you have limited capital, or you want to test something cheaply without committing.

Buying suits you if you need income from the business relatively quickly, you have capital or can raise it, you are better at improving an existing operation than inventing one, you want scale sooner than you could build it, or you have sector experience you can apply to something already trading.

The middle option, which people forget: buy a small business and grow it. Acquiring something established and unglamorous, then applying capability the previous owner did not have, is how a great many substantial businesses were actually built. It is less appealing as a story and the arithmetic is considerably better than starting.

A different way to decide

Answer three questions honestly.

Has anybody paid for your idea yet? If yes, starting is more attractive than the statistics suggest, because you have passed the test most new businesses fail. If no, and you have been at it a while, that is information.

What could you lose, and could you take it? Starting risks time and modest capital. Buying risks substantial capital that is often secured against your home. Neither answer is wrong. They are different bets and you should know which one you are placing.

Do you want to build something, or run something? These are genuinely different activities and most people are better at one. Founders who acquire often find the constraints frustrating. Operators who start often find the years without a system exhausting.

And the honest conclusion

For most people with limited capital and an untested idea, starting is the right answer, and the low cost of trying is the whole argument.

For people with capital or borrowing capacity, management experience and a preference for running something over inventing something, buying is frequently better, and the five-year survival figure is the reason.
