Buying an established business in London can be a safer way into ownership than starting from nothing, because you take on customers, staff, suppliers and a trading record from day one. It is not risk-free. The record may be weaker than it looks, and some of the value can leave with the previous owner. This guide from The London Report sets out the real benefits, what official data says about the odds, and what to check before you rely on each benefit.
It is part of a short series with our guides on buying a business in London, the top industries for businesses for sale in London and how to finance a London business purchase. For more, see our business section. This is general information, not financial or legal advice.
Key takeaways
- Only 38.4% of UK businesses born in 2019 were still trading five years later, according to the ONS. Starting from scratch is the riskier path, though the ONS does not compare it with buying.
- London has a higher business birth rate (12.7%) than the UK (11.1%) and the most high-growth firms (3,540, or 6.6% of firms with 10 or more employees).
- The main benefits are an existing customer base, a trading record, staff, suppliers and quicker cash flow, but each one needs checking in the numbers.
- Staff usually transfer with their terms under TUPE. A genuine going-concern sale can be outside VAT. Buying shares costs 0.5% stamp duty.
- Always do due diligence: a buyer who skips it can inherit hidden debts, weak contracts or lost customers.
Why more people look at established businesses
Starting a business is common, and surviving is harder. The ONS reports that the UK had about 317,000 business births in 2024 and 280,000 deaths, and that of the businesses born in 2019, 38.4% survived to 2024 (ONS, Business demography, UK: 2024). That is a UK-wide figure for new businesses of all types, so it does not prove that every purchase is safer. It does explain why many buyers prefer a business that has already got past the start-up years.
London is a busy place to do this. Its birth rate is the highest of any region, and so is its competition, which is why buyers often want a business with a track record.
Buying an established business vs starting from scratch
The table compares the two routes on the points buyers ask about most. It is an editorial summary, so use it as a prompt for your own checks.
| Factor | Buy an established business | Start from scratch |
|---|---|---|
| Customers on day one | Usually yes, if the customer list is real and stays | No. You build from zero |
| Trading record | Accounts and tax returns you can review | None. Lenders rely on your plan |
| Staff | Often transfer with you under TUPE, on their existing terms | You recruit and train |
| Up-front cost | Purchase price plus legal and due diligence fees | Set-up costs, but no purchase price |
| Main risk | Overpaying, or buying hidden debts and lost customers | Not reaching enough customers before cash runs out |
| Speed to first income | Faster, because trading continues | Slower, usually months of build-up |
Established customer base
A business with regular customers gives you income from the first week, with less pressure on marketing. That is the main reason people buy rather than build. In London, where customers have a lot of choice, a loyal base can be worth paying for.
Check before you rely on it: ask for sales by customer or month for the last three years. If a few customers make up most of the sales, or sales depend on the owner’s personal relationships, the base may not transfer.
A proven business model
When a business has traded for years, you can see which products sell, what the margins are and which months are quiet. You can improve what already works rather than guessing. A London restaurant that has been profitable for five years, for example, knows its peak hours and best sellers.
Check: the accounts. Profit that rests on one unusual year, or on the owner working unpaid hours, is not the same as a proven model.
Brand recognition and online reach
A known name saves years of marketing. Customers who already trust the business may keep coming and recommend it. You can then add new routes to market, such as selling online. Our guide to starting an e-commerce business covers that step.

Experienced employees and TUPE
Staff who know the customers and the routines are one of the most valuable things you inherit. Under the Transfer of Undertakings (Protection of Employment) rules, known as TUPE, employees’ jobs usually transfer to the new owner, their terms and conditions transfer too, and their continuity of employment is kept. Exceptions include redundancies, and in some cases insolvent businesses (GOV.UK: Business transfers, takeovers and TUPE).
Check: who is employed, on what terms, and who the key people are. If one manager holds the customer relationships, plan how to keep them.
Supplier relationships and stock
Established suppliers can mean reliable deliveries and agreed terms. Look at which contracts transfer to you and which end on sale. Once you own the business, tools such as the best inventory control software can help you track stock and cut waste.
Check: supplier contracts, any exclusive deals and how much stock is included in the price.
Easier access to finance
A lender can look at real accounts rather than a forecast, which can make it easier to assess the risk. Do not assume it will be easy, though. Lenders still look at affordability and security. The Growth Guarantee Scheme, for instance, gives lenders a 70% guarantee, but the borrower stays 100% liable (British Business Bank). Our guide to how to finance a London business purchase compares the main routes, and our guide to business loans covers the loan types.
Immediate cash flow
A trading business pays its bills from the start, so rent, wages and utilities are covered by income rather than by your savings. This is the benefit buyers value most after customers. But cash flow can dip after a handover, so keep working capital in reserve.
Check: monthly bank statements against the accounts, and any seasonal swings.
Lower start-up costs
Fit-out, equipment, licences and the first marketing push are often already in place. That can leave more money for improving the business. If you later want to add a new line, our list of profitable business ideas may help. Note that you still pay the purchase price, plus legal fees, due diligence and, if you buy shares, 0.5% stamp duty (GOV.UK).
Market presence in a crowded city
London had an estimated 1.042 million private sector businesses at the start of 2025, the most of any UK region (DBT Business Population Estimates 2025). Being already in the market, with a known location and reputation, helps. It also means competitors are close, so check what you are really buying: the lease, the location and the local competition.
Potential for growth
London also leads on high-growth businesses. The ONS counted 3,540 high-growth firms in London in 2024, a rate of 6.6% of firms with 10 or more employees, against 4.9% for the UK (ONS). That does not mean a bought business will grow, but it shows the city rewards firms that do. A purchase can be a platform: new services, delivery, online sales or a second site.
Legal and due diligence checks
Due diligence means checking the business before you commit. It is where most of the protection is. Start with what you are buying: shares in the company, or its assets. These have different legal and tax effects, so take advice before you agree anything (iwoca).
| Check | What to look for | Source |
|---|---|---|
| Company records | Registered details, officers, charges (security held by lenders) and insolvency history. Free to search | GOV.UK: Companies House |
| Accounts and tax | At least three years of accounts, tax returns and bank statements that agree with each other | Your accountant |
| Staff | Who transfers, on what terms, and any claims | GOV.UK: TUPE |
| VAT | A sale of a genuine going concern can be outside VAT if the conditions are met, so check before you pay VAT on the price | GOV.UK: VAT Notice 700/9 |
| Stamp duty | 0.5% on shares; Stamp Duty applies on a stock transfer form over £1,000 | GOV.UK: Tax when you buy shares |
| Contracts and lease | Which customer, supplier and property contracts transfer, and whether the landlord must agree | Your solicitor |
Understanding the risks
- Hidden debts or claims. Buying shares means you take on the company’s history. Buying assets can limit that, but changes the tax and contract position.
- Customers who leave. Some sales depend on the owner. Ask for a handover period in the contract.
- Overpaying. A price based on one good year can be too high. Have an accountant test it.
- Falling demand or old systems. A business can be established and still be in decline.
- Using too much debt. Check you can repay loans in a weak month, and know what personal guarantee you may be giving.
Cover the practical risks with the right business insurance from day one. A careful buyer lowers these risks, but cannot remove them.
Conclusion
Buying an established business in London gives you customers, staff, suppliers and a trading record that a start-up has to build. The benefits are real only if the numbers back them up. Use the checks above, take legal and tax advice, and plan your funding before you make an offer.
FAQs
What are the benefits of buying an established business?
The main benefits are existing customers, a trading record, staff and suppliers already in place, quicker cash flow and a business model that has been tested. Each should be checked in the accounts and contracts before you rely on it.
Is buying a business safer than starting one?
Often it is less uncertain, but not risk-free. The ONS found that 38.4% of UK businesses born in 2019 survived to 2024, but it does not compare purchases with start-ups (ONS). Due diligence decides how safe a particular purchase is.
What are the risks of buying an established business?
Hidden liabilities, customers who leave with the owner, an inflated price, outdated systems and falling demand. Proper due diligence reduces these risks.
How do I find established businesses for sale in London?
Use online marketplaces and business brokers, and read our business section for guides. Our top industries for businesses for sale in London guide shows which sectors to look at.
How can I finance the purchase?
Most buyers combine a bank or specialist loan, some seller finance and their own deposit. See our guide to how to finance a London business purchase for the UK options.
What is due diligence?
It is the process of checking a business’s finances, contracts, staff, tax and legal position before you buy it. A solicitor and an accountant usually carry it out.
Do the employees come with the business?
Usually, yes. Under TUPE, employees’ jobs generally transfer to the new owner with their existing terms (GOV.UK).
Do I pay VAT when I buy a business?
Not always. If the sale qualifies as a transfer of a going concern, no VAT should be charged. The conditions are strict, so check them (GOV.UK).
Can I change the business after buying it?
Yes, but make changes gradually. Keep what customers value, and review staff, suppliers and pricing once you understand the numbers.
