Setting up a limited company in the UK is one of the cheapest things you will ever do in business. The actual registration costs almost nothing. But the real expenses come from everything around it: accountants, insurance, banking, and the bits nobody tells you about until you are already committed.
This guide covers every cost you should expect when forming a UK limited company in 2026, from day one through to your first year of trading.
Registering a limited company costs as little as £12 online through Companies House. But realistic first year costs including an accountant, insurance, and basic setup sit between £1,000 and £3,000 for most small businesses.
Companies House Registration
This is the only mandatory cost. You cannot trade as a limited company without registering with Companies House. The fees are straightforward and have not changed much in recent years.
| Registration Method | Cost | Turnaround |
|---|---|---|
| Online (GOV.UK) | £12 | Usually within 24 hours |
| Postal application | £30 | 8 to 10 working days |
| Same day service | £30 | Same day (submitted by 3pm) |
The online route is the obvious choice for most people. You fill in a form on the GOV.UK website, pay £12, and your company is usually registered within a few hours. There is no reason to use the postal route unless you are filing unusual articles of association.
The same day service is useful if you need the company number immediately, for example to sign a contract or open a bank account that day. At £30 it is not expensive, but most people do not need it.
Formation Agents
You do not need a formation agent to register a company. The GOV.UK process is simple enough for anyone to complete. However, formation agents offer packages that bundle in extras like a registered office address, digital document storage, and mail forwarding.
| Service | Typical Cost | What You Get |
|---|---|---|
| Basic formation package | £10 to £50 | Company registration only |
| Standard package | £30 to £100 | Registration + registered office address |
| Premium package | £80 to £200 | Registration + office + mail forwarding + documents |
The main reason to use a formation agent is if you work from home and do not want your home address on the public register. A registered office address costs £30 to £80 per year through most agents and keeps your personal address private.
Accountant Costs
You are legally required to file annual accounts and a corporation tax return with HMRC. You can do this yourself, but most limited company directors hire an accountant. It is one of those costs that pays for itself because a decent accountant will save you more in tax than they charge in fees.
| Accountant Type | Annual Cost | What Is Included |
|---|---|---|
| Online accountant (FreeAgent, Crunch) | £300 to £600/year | Software, basic support, filings |
| Local high street accountant | £500 to £1,500/year | Personal service, annual accounts, tax returns |
| Specialist small business accountant | £800 to £2,000/year | Proactive tax planning, payroll, VAT |
For a straightforward one person limited company, expect to pay between £500 and £1,000 per year. If you are VAT registered, have employees, or deal with complex invoicing, that figure moves towards £1,500 or higher.
Your accountant fees are a tax deductible business expense. A good accountant will also help you structure your salary and dividends to minimise your personal tax bill, which can easily save you £2,000 to £5,000 per year.
Business Bank Account
You are not legally required to have a separate business bank account as a limited company director, but you should. Mixing personal and business finances is a headache for your accountant and a red flag for HMRC if you are ever investigated.
| Bank Type | Monthly Cost | Notes |
|---|---|---|
| Digital bank (Starling, Tide, Revolut) | £0 to £10/month | Free basic tier, fast setup, app based |
| High street bank (Lloyds, NatWest, HSBC) | £5 to £15/month | Free for 12 to 18 months, then charges apply |
| Premium business account | £15 to £30/month | Dedicated account manager, credit facilities |
Most new limited companies start with a free digital bank account from Starling or Tide. These are perfectly adequate for a small business. The high street banks offer free banking for the first year or so, but their fees kick in afterwards and their onboarding process is painfully slow compared to the digital options.
Insurance
The insurance you need depends on what your company does. Some types are legally required. Others are technically optional but practically essential.
| Insurance Type | Annual Cost | Required? |
|---|---|---|
| Employers liability (if you have staff) | £80 to £300/year | Legally required with employees |
| Public liability | £50 to £300/year | Not legally required but often contractually required |
| Professional indemnity | £100 to £500/year | Essential for consultants, advisors, creatives |
| Contents and equipment | £50 to £200/year | Optional but sensible |
If you are a sole director with no employees, no premises, and you work from home providing a professional service, you might get away with just professional indemnity insurance at around £100 to £200 per year. If you work with the public or visit client sites, add public liability on top of that.
Other First Year Costs
- Domain name: £8 to £15 per year for a .co.uk
- Email hosting: £0 to £5 per month (Google Workspace starts at £5.20/month)
- Basic website: £0 to £500 depending on whether you build it yourself or hire someone
- Business cards and stationery: £20 to £100
- Accounting software: £0 to £35 per month (often included with your accountant)
- HMRC registration: £0 (free, but you must register for Corporation Tax within 3 months of trading)
- ICO data protection registration: £35 to £60 per year (required if you process personal data)
Hidden Costs Most People Miss
The costs listed above are the ones you will find in every guide. But there are several recurring charges that catch new directors off guard because nobody mentions them until the first invoice arrives.
Confirmation statement filing: Every company must file a confirmation statement with Companies House at least once every 12 months. The fee is £13 if you file online or £40 by post. It is not a large amount, but forgetting to file it is one of the most common reasons companies get struck off the register. Companies House sends reminders, but they go to your registered office address, so if that is a virtual address and you do not check the forwarded mail, you may not see them in time.
Registered office service fees: If you use a formation agent or virtual office provider for your registered office address, the annual renewal fee is typically £50 to £200 per year. The lower end covers a basic address with annual mail forwarding, while the higher end includes scanning of all incoming post and forwarding it to you digitally within 24 hours. Some providers charge extra for Companies House mail specifically, so read the terms carefully before signing up. This is a recurring annual cost that many new directors budget for in year one but forget about in year two.
ICO data protection registration: If your business holds or processes any personal data (which includes client names, email addresses, phone numbers, or employee records), you must register with the Information Commissioner's Office. The fee for most small businesses is £35 per year, rising to £60 if your turnover exceeds £632,000. Failing to register when required is a criminal offence, and the ICO can issue fines of up to £4,350. Most limited companies need to register, and many do not realise it until they receive a letter from the ICO.
Directors' personal insurance: As a company director, you have legal duties under the Companies Act 2006. If something goes wrong, you can be held personally liable for certain decisions. Directors and officers (D&O) insurance covers legal costs and settlements if a claim is made against you personally. For a small company, this costs £100 to £400 per year. It is not mandatory, but it is strongly recommended once your company is trading with clients, suppliers, or employees.
Payroll costs: If you pay yourself a salary (which most limited company directors do for tax efficiency), you need to run payroll. Your accountant may include basic payroll in their package, but some charge extra for this service, typically £5 to £15 per payslip. If you run monthly payroll for yourself as the sole director, that is an additional £60 to £180 per year on top of your accountant's base fee. Alternatively, you can use free payroll software from HMRC (Basic PAYE Tools), but it requires manual setup and quarterly reporting.
Annual accounts preparation: This is technically included in most accountant packages, but if you are doing your own accounts, you will need filing software. Companies House accepts iXBRL format accounts, and the software to produce these costs £100 to £300 per year if purchased separately. This is another reason most directors hire an accountant rather than doing it themselves.
Regional Cost Differences
Where you are based in the UK affects what you pay for several key services. The most significant regional variation is in accountancy fees, but virtual office addresses and insurance premiums also vary by location.
| Region | Accountant (Annual) | Virtual Office (Annual) |
|---|---|---|
| London (Central) | £800 to £2,500 | £150 to £400 |
| London (Outer) | £600 to £1,800 | £100 to £250 |
| South East England | £500 to £1,500 | £80 to £200 |
| Midlands | £400 to £1,200 | £50 to £150 |
| North of England | £350 to £1,000 | £40 to £120 |
| Scotland | £400 to £1,200 | £50 to £150 |
| Wales | £350 to £1,000 | £40 to £120 |
| Northern Ireland | £350 to £1,000 | £40 to £100 |
London accountants charge a premium because their own overheads are higher and because London based businesses tend to have more complex affairs. However, there is nothing stopping you from using an accountant based elsewhere in the country. Online accountancy services like FreeAgent and Crunch charge the same flat rate regardless of where you are, which is one reason they have become so popular with new limited companies outside London.
Virtual office addresses show a similar pattern. A prestigious London W1 address costs £200 to £400 per year, while a business address in Manchester, Leeds, or Birmingham runs £50 to £150. Some directors deliberately choose a London registered office for the credibility it offers, even though their actual business operates from another part of the country. This is perfectly legal and surprisingly common.
Insurance premiums are less affected by region, though businesses in London and the South East do pay slightly higher rates for professional indemnity and public liability cover. The difference is typically 10 to 20% above the national average, reflecting higher claim values in those areas.
When a Limited Company Saves You Money
The main financial advantage of a limited company over being a sole trader is tax efficiency. As a sole trader, you pay income tax and Class 2 and Class 4 National Insurance on all your profits. As a limited company director, you pay yourself a combination of salary and dividends, which is taxed at lower rates.
The table below compares the approximate annual tax bills for a sole trader versus a limited company director at different income levels in the 2025/26 tax year. The limited company figures assume a salary of £12,570 (the personal allowance) with the remainder taken as dividends, and account for Corporation Tax at 19% on profits up to £50,000 (the small profits rate) and 25% above £250,000.
| Annual Profit | Sole Trader Tax Bill | Limited Company Tax Bill | Annual Saving |
|---|---|---|---|
| £25,000 | £3,900 | £3,200 | £700 |
| £40,000 | £8,200 | £6,100 | £2,100 |
| £60,000 | £15,400 | £11,200 | £4,200 |
| £80,000 | £23,100 | £17,500 | £5,600 |
These figures are approximate and depend on your individual circumstances, but they illustrate why most accountants recommend switching to a limited company once your profits exceed £30,000 to £40,000 per year. At £25,000, the tax saving of roughly £700 only just covers the additional admin costs of running a limited company. At £40,000, the £2,100 saving comfortably pays for an accountant, accounting software, and filing fees with money left over. By £60,000, the saving is substantial enough that staying as a sole trader costs you real money.
It is worth noting that these calculations do not account for employer pension contributions, which a limited company can make as a tax deductible business expense. A sole trader can claim pension contributions against income tax, but a limited company director can have the company pay directly into their pension, avoiding both Corporation Tax and personal income tax on that amount. For higher earners, this adds thousands more in annual savings.
The tax figures above change with each budget. Always ask your accountant to model the exact comparison for your situation before deciding to incorporate. The direction of the saving is consistent (limited company is almost always cheaper above £30,000), but the exact amounts shift with each change to tax rates and thresholds.
VAT Registration and Making Tax Digital
VAT registration becomes mandatory once your taxable turnover exceeds £90,000 in any rolling 12 month period. You must register within 30 days of the end of the month in which you crossed the threshold, or immediately if you expect your turnover to exceed £90,000 in the next 30 days alone. Late registration results in a penalty based on the tax you owe from when you should have registered.
Voluntary VAT registration is worth considering even below the threshold if your business sells primarily to other VAT registered businesses (B2B) or if you have significant VAT reclaimable purchases. When your clients are VAT registered themselves, they reclaim the VAT you charge, so it costs them nothing, but you get to reclaim VAT on all your business purchases. This is particularly beneficial for businesses with high expenses on equipment, materials, or subcontractor costs.
Making Tax Digital (MTD) requires all VAT registered businesses to keep digital records and submit VAT returns through MTD compatible software. This means you cannot simply file a VAT return through the HMRC website; you must use software such as Xero, QuickBooks, FreeAgent, or one of the other HMRC recognised providers. Most accounting software packages already include MTD compliance, so if you are using an accountant with a software package, this is likely covered. If you are doing your own VAT returns, budget £10 to £30 per month for MTD compatible software.
MTD for Corporation Tax is expected to become mandatory for companies with turnover above £50,000 from April 2026. This will require quarterly digital updates to HMRC rather than a single annual return. Your accountant should already be preparing for this change, but it is worth confirming that their fees account for the additional quarterly filing work.

Month by Month: Your First Year
Not all costs hit at once. Here is roughly when you should expect to spend what during your first 12 months as a limited company.
Month 1: Companies House registration (£12), registered office address if needed (£30 to £80), business bank account setup (free). Total: roughly £12 to £100.
Month 2: Accountant onboarding (first payment, typically £50 to £150), accounting software subscription (£0 to £35), ICO registration (£35 to £60), domain name and email setup (£15 to £80). Total: roughly £100 to £325.
Month 3: Insurance policies (£100 to £500 depending on what you need), HMRC Corporation Tax registration (free but must be done within 3 months of trading). Total: roughly £100 to £500.
Months 4 to 6: Website if you want one (£0 to £500), business cards (£20 to £100), ongoing accountant and software fees. You may also register for VAT if turnover is approaching £90,000 or if voluntary registration makes sense for your business.
Months 7 to 12: Ongoing monthly costs only. Accountant fees, software, bank charges (if applicable), insurance renewals. Some directors start thinking about pension contributions around this point. The minimum employer contribution is 3% of qualifying earnings.
Total First Year Cost
| Scenario | Estimated First Year Cost |
|---|---|
| Bare minimum (solo, home based, no staff) | £300 to £800 |
| Typical small business (accountant, insurance, basic setup) | £1,000 to £2,500 |
| Professional services (with PI insurance, website, branding) | £2,000 to £4,000 |
| Trade business (with premises, van insurance, tools) | £5,000 to £15,000 |
How to Reduce Your Startup Costs
There are several practical ways to keep your first year costs under £1,000 without cutting corners that matter.
- Register directly with Companies House. The £12 online route is faster and cheaper than any formation agent. Save the agent fee unless you specifically need a registered office address.
- Use a free business bank account. Starling Business and Tide both offer free accounts with no monthly fees for basic banking. You can always upgrade later.
- Start with an online accountant. Services like FreeAgent (from £15/month) or Crunch (from £25/month) include software and basic support. You do not need a specialist accountant until your affairs become more complex.
- Build your own website. A basic one page website on Carrd costs £19 per year. WordPress on affordable hosting costs £30 to £60 per year. You do not need a £2,000 website on day one.
- Bundle your insurance. Buying public liability and professional indemnity together from the same provider is typically 15 to 25% cheaper than buying them separately.
- Delay non essential spending. Business cards, premium email, and branding can wait until you have revenue coming in. Focus on the things that let you trade legally and get paid.
Common Mistakes That Cost You More
New limited company directors regularly make the same avoidable mistakes. Each one costs real money.
- Not registering for Corporation Tax on time. You must register within 3 months of starting to trade. Missing this deadline can result in penalties starting at £100 and increasing the longer you leave it.
- Mixing personal and business finances. Using your personal bank account for business transactions makes your accounts harder to prepare, costs more in accountancy fees, and raises red flags with HMRC if you are investigated.
- Not keeping receipts. Every allowable expense reduces your Corporation Tax bill. At 25% Corporation Tax (the current rate for companies with profits over £250,000) or 19% for smaller profits, losing £5,000 in receipts costs you £950 to £1,250 in extra tax.
- Paying too much salary. A common beginner mistake is paying yourself entirely through salary (PAYE). A blend of salary and dividends is almost always more tax efficient. Your accountant will set this up for you.
- Ignoring the confirmation statement. Companies House requires an annual confirmation statement (£13 online, £40 by post). Forgetting to file it can result in your company being struck off the register.
- Over investing in branding early. Spending £3,000 on a logo and brand identity before you have any clients is a common trap. A clean, simple brand costs under £200 and serves perfectly well until your business is established.
Do You Need Qualifications?
No. There are no qualifications required to set up or direct a limited company in the UK. You must be at least 16 years old, not be an undischarged bankrupt, and not be disqualified from acting as a company director. That is the full list of requirements.
Some regulated professions require specific qualifications before you can trade (accountancy, law, financial advice, healthcare), but these are requirements of the profession rather than the company structure. The limited company itself can be formed by anyone.
How Long Until You Break Even?
Since a limited company is a business structure rather than a business type, break even depends entirely on what your company does. However, the overhead costs of running the company itself are low enough that they rarely affect your break even point.
Low cost scenario (freelancer, consultant): If your only company costs are £100/month for accountant and software, you need to earn just £100/month to cover company overheads. Most freelancers cover this within their first week of trading.
Typical scenario (small business with insurance and website): Monthly company costs of £150 to £250 are covered by most businesses within the first month, separate from your actual product or service costs.
Higher cost scenario (trade business with premises): If you have premises, vehicle costs, and staff, your break even is driven by those costs rather than the company structure costs. Budget 3 to 6 months to reach break even in most trade businesses.
The key point is that the cost of being a limited company (as opposed to a sole trader) is typically only £500 to £1,500 per year in additional admin costs. If your accountant is saving you £2,000+ in tax through salary and dividend planning, you are already ahead.
Starting a limited company in the UK costs £12 at Companies House. But a realistic budget for your first year of proper trading, including an accountant and basic insurance, is £1,000 to £2,500. That is genuinely cheap compared to almost any other country in the world.
Frequently Asked Questions
Is it free to set up a limited company?
No, but it is close. The cheapest route is £12 through the GOV.UK online service. Some formation agents advertise free company registration but charge for the extras you will need anyway.
Do I need an accountant for a limited company?
Legally, no. Practically, yes. Limited company accounts are more complex than self assessment tax returns. A good accountant will save you more in tax efficiency than they charge in fees. Budget £500 to £1,000 per year.
Can I use my home address as the registered office?
Yes, but be aware that your registered office address is public information. Anyone can look it up on the Companies House register. If you want privacy, use a registered office service for £30 to £80 per year.
How long does it take to set up a limited company?
The actual registration takes about 15 minutes online and your company is usually incorporated within 24 hours. Opening a bank account, setting up with HMRC, and getting insurance sorted will take a few more days to a couple of weeks.
What is the difference between a sole trader and a limited company?
A sole trader is simpler and cheaper to run, but you are personally liable for business debts. A limited company separates your personal and business finances, which protects your personal assets. Most people switch to a limited company once they are earning over £30,000 to £40,000 per year because the tax savings outweigh the extra admin costs.
When should I switch from sole trader to limited company?
The crossover point depends on your specific circumstances, but most accountants recommend considering the switch when your taxable profits reach £30,000 to £40,000 per year. At that level, the tax savings from paying yourself through a salary and dividends combination typically outweigh the additional admin costs of running a limited company. Your accountant can model the exact numbers for your situation.
What happens if my limited company makes a loss?
If your limited company makes a loss, you do not pay Corporation Tax for that period. The loss can be carried forward and offset against future profits, reducing your tax bill in profitable years. This is one advantage over being a sole trader, where loss relief rules are more restrictive.
Do I need to register for VAT?
You must register for VAT if your taxable turnover exceeds £90,000 in any rolling 12 month period. Below that threshold, VAT registration is voluntary. Some businesses register voluntarily because they can reclaim VAT on purchases, which is beneficial if you have high business expenses. Your accountant can advise whether voluntary registration makes financial sense for your situation.
