Starting a business in the UK is surprisingly affordable. You can legally register and begin trading for less than the price of a round of drinks. But the real cost is not the registration. It is everything that comes after: insurance, accounting, a bank account, a website, and the dozen other things you only find out about once you are already in motion.
This guide covers every startup cost you should expect in 2026, whether you are launching a home based freelance business or opening a shop on the high street. We have broken it down into categories so you can build a realistic budget before you commit to anything.
A home based service business can launch for as little as £100 to £500. A typical small business with premises, insurance, and professional support should budget £2,000 to £10,000 for the first year. Retail, hospitality, and trade businesses often need £10,000 to £50,000 or more depending on the sector.
1. Business Registration
Every business in the UK needs to be registered in some form. The cost depends entirely on which structure you choose.
| Business Structure | Registration Cost | Where to Register |
|---|---|---|
| Sole trader | Free | HMRC (online) |
| Limited company (online) | £100 | Companies House |
| Limited company (same day) | £156 | Companies House |
| Business partnership | Free | HMRC (each partner registers separately) |
If you are starting small and testing an idea, registering as a sole trader is the obvious first step. It costs nothing and takes about 15 minutes online. If you want the liability protection and potential tax benefits of a limited company, registration is £100 through Companies House as of February 2026. We cover the full breakdown in our guide to limited company startup costs.

2. Insurance
Insurance is one of those costs that feels optional until something goes wrong. Some types are legally required. Others are practically essential even when they are not.
| Insurance Type | Annual Cost | Who Needs It |
|---|---|---|
| Public liability | £50 to £300/year | Anyone working with the public or on client sites |
| Employers liability | £60 to £300/year | Legally required if you have any employees |
| Professional indemnity | £100 to £500/year | Consultants, advisors, designers, anyone giving professional advice |
| Contents and equipment | £50 to £200/year | Anyone with tools, stock, or expensive equipment |
| Product liability | £60 to £400/year | Anyone manufacturing or selling physical products |
For a solo consultant working from home, you might only need professional indemnity insurance at around £100 to £200 per year. A tradesperson visiting client homes will need public liability as a minimum, and most clients will insist on it before hiring you. If you hire even one employee, including part time staff, you are legally required to hold employers liability insurance. For a deeper look at public liability costs specifically, see our public liability insurance cost guide.
3. Business Bank Account
If you are a limited company, you should keep your business finances completely separate from your personal accounts. Sole traders are not legally required to have a separate account, but it makes life significantly easier when it comes to tax returns.
| Bank Type | Monthly Cost | Notes |
|---|---|---|
| Digital bank (Starling, Tide, Revolut) | £0 to £10/month | Free basic tier, app based, fast setup |
| High street bank (Lloyds, NatWest, HSBC) | £5 to £15/month | Usually free for 12 to 18 months, then monthly fees |
| Premium business account | £15 to £30/month | Dedicated account manager, credit facilities |
The digital banks are the best option for most startups. Starling and Tide both offer free business current accounts with no monthly fees on the basic tier. You can be set up and making payments within a day. The high street banks still have their place if you need to deposit cash regularly, but their onboarding process is painfully slow by comparison.
4. Accounting and Tax
Every business needs to deal with tax. How much you spend on accounting depends on your business structure and how comfortable you are with numbers.
| Service | Sole Trader Cost | Limited Company Cost |
|---|---|---|
| DIY with software only | £0 to £15/month | £15 to £35/month |
| Online accountant (Crunch, Ember) | £150 to £400/year | £300 to £600/year |
| High street accountant | £200 to £500/year | £500 to £1,500/year |
| Specialist accountant (VAT, payroll, tax planning) | £400 to £800/year | £800 to £2,000/year |
Sole traders can realistically manage their own books using free software like Wave or a simple spreadsheet, at least for the first year. A self assessment tax return can be filed for free through the HMRC website. Limited companies have more complex filing requirements and almost always benefit from hiring an accountant. The fee pays for itself through tax savings in most cases.
Accountancy fees are a tax deductible business expense. If your accountant saves you more in tax than they charge in fees, which a good one should, they are effectively free.
5. Website and Online Presence
Almost every business needs some form of online presence. The costs range from nothing to thousands depending on what you need.
| Option | Setup Cost | Monthly Running Cost |
|---|---|---|
| Google Business Profile only | Free | Free |
| Social media pages (Instagram, Facebook) | Free | Free |
| DIY website builder (Wix, Squarespace) | £0 to £50 | £10 to £30/month |
| WordPress website (self hosted) | £50 to £200 | £5 to £30/month |
| Professional website (agency or freelancer) | £500 to £5,000+ | £10 to £50/month |
If you are a local service business, a Google Business Profile and a simple one page website are all you need to start. You can build something decent yourself on Squarespace for under £200 in your first year. If your business depends on attracting customers online, investing in a proper website early on will pay dividends. A .co.uk domain costs around £8 to £15 per year, and professional email hosting through Google Workspace starts at £5.20 per month.
6. Marketing and Advertising
You can start marketing for nothing, or you can spend thousands. Most small businesses fall somewhere in between.
| Marketing Channel | Budget | Mid Range | Premium |
|---|---|---|---|
| Business cards and flyers | £20 | £50 to £100 | £200+ |
| Social media (organic) | Free | Free | Free |
| Google Ads | £100/month | £300/month | £1,000+/month |
| Facebook/Instagram Ads | £50/month | £200/month | £500+/month |
| Logo and branding | £0 (DIY) | £100 to £300 | £500 to £2,000 |
In the early days, word of mouth and organic social media are free and usually more effective than paid advertising. Most new businesses do not need to spend money on Google Ads in their first few months. Focus on building a solid reputation first and let paid advertising amplify what is already working.
7. Premises and Equipment
This is where costs vary most dramatically. A freelancer working from their kitchen table has zero premises costs. A cafe opening on a high street could spend £30,000 before serving a single cup of coffee.
| Premises Type | Monthly Cost | Notes |
|---|---|---|
| Home based (no dedicated space) | £0 | Claim a proportion of household bills as business expense |
| Co working desk (hot desk) | £100 to £250/month | Flexible, no long term commitment |
| Small office or studio | £200 to £800/month | Varies hugely by location |
| Retail unit (high street) | £500 to £3,000+/month | Plus business rates, service charges, deposit |
| Workshop or industrial unit | £300 to £1,500/month | Better value per square foot than retail |
If you can run your business from home, do it. At least for the first year. It keeps your overheads as close to zero as possible and gives you time to figure out whether the business model works before committing to a lease. Once you need premises, co working spaces offer a good middle ground with short term flexibility.
Equipment costs are entirely sector specific. A cleaning business might need £200 in supplies. A barber shop might need £5,000 in chairs and equipment. A cafe could need £15,000 or more in commercial kitchen equipment. We cover these in detail in our industry specific guides.
8. Licences and Regulations
Some businesses need specific licences or registrations beyond basic registration. These are not always obvious, so it is worth checking before you launch.
- ICO data protection registration: £35 to £60/year (required if you hold customer data)
- Food business registration: Free (register with your local council at least 28 days before opening)
- Alcohol licence (premises): £100 to £1,905 depending on rateable value
- Street trading licence: £20 to £500 depending on the council
- Waste carrier licence: £154 for lower tier (free), £170 for upper tier
- DBS check: £18 to £38 (for roles working with children or vulnerable adults)
Total Startup Cost Summary
Here is what you should realistically budget depending on your type of business.
| Business Type | Budget Estimate | Realistic Estimate |
|---|---|---|
| Home based freelancer or consultant | £100 to £500 | £500 to £1,500 |
| Service business (cleaning, gardening, dog walking) | £300 to £1,000 | £1,000 to £3,000 |
| Trade business (plumber, electrician, builder) | £2,000 to £5,000 | £5,000 to £15,000 |
| Online business (ecommerce, digital products) | £200 to £1,000 | £1,000 to £5,000 |
| Retail shop | £5,000 to £15,000 | £15,000 to £40,000 |
| Cafe or food business | £10,000 to £25,000 | £25,000 to £80,000 |
| Salon (hair, beauty, barber) | £5,000 to £15,000 | £15,000 to £40,000 |
The cost of starting a business in the UK depends almost entirely on what kind of business you are starting. A home based service business can genuinely launch for a few hundred pounds. A business that needs premises, equipment, and staff will need thousands. The one constant is this: almost everyone underestimates how much they will spend in their first year. Build your budget, then add 20% on top for the things you have not thought of yet.

Frequently Asked Questions
Can I start a business in the UK with no money?
Technically, yes. Registering as a sole trader with HMRC is free, and you can trade using your own name without any upfront costs. In practice, most businesses need at least a few hundred pounds for insurance, basic tools or software, and accounting support. But there is no legal minimum spend to get started.
What is the cheapest type of business to start in the UK?
Service businesses that you can run from home with no stock and no premises are the cheapest to start. Freelance writing, virtual assistance, social media management, tutoring, and consulting can all be launched for under £500. The biggest costs are usually just insurance and accounting software.
Do I need to register my business before I start trading?
If you are a sole trader, you must register with HMRC by 5 October after the end of the tax year in which you started trading. If you are setting up a limited company, you must register with Companies House before you start trading. Either way, registration should be one of the first things you do.
Should I start as a sole trader or a limited company?
Most people start as sole traders because it is simpler and cheaper. A limited company becomes more tax efficient once you are earning over £30,000 to £40,000 in profit per year, but it comes with more admin and higher accountancy costs. We cover this in detail in our sole trader vs limited company comparison.
What ongoing costs should I budget for after year one?
The main recurring costs are accounting fees, insurance renewals, software subscriptions, and your tax bill. Limited companies also need to file a confirmation statement with Companies House each year (£50 online). Budget for these as fixed monthly outgoings so they do not catch you off guard.
