Starting a business in the UK has never been more accessible. If you've been searching for a way to register a company for free, you're not alone - over 2 million limited companies are registered in the UK, and new business owners launch thousands more every month.
This guide walks you through how free company registration actually works in 2026, what's changed since the Companies House fee increase, and exactly how to go from idea to incorporated company without paying a penny upfront.
Key Takeaways
You can register a UK limited company for £0 upfront by using a company formation package that refunds or covers the £100 Companies House fee when you open and use a linked business bank account.
Most "register a company for free" offers are conditional: you usually must open a partner business bank account and meet a minimum spend (for example £100 within 30 days) or subscribe to a low-cost annual plan.
The quick overview is just four steps: choose a company name, complete an online form with your company details, let the provider file with Companies House, then activate your free business bank account.
Free registration applies to private limited companies (Ltd). Sole traders do not register with Companies House and have a different, already-free HMRC registration process.
The whole company registration process normally takes 3–24 working hours in 2026, with all company documents - certificate of incorporation, articles, share certificates - emailed digitally.
How “Register a Company for Free” Really Works in 2026
Let's get the important bit out of the way: registering a company involves a statutory fee to incorporate a company in the UK. Companies House charges £100 for company registration in the UK as of February 2026. That fee previously sat at £50, but it doubled to fund new anti-fraud measures under the Economic Crime and Corporate Transparency Act.
So when a provider advertises that you can register a company for free, they're not bypassing the fee - they're paying it for you. The company formation agent or banking partner covers the £100 Companies House fee on your behalf, and recoups that cost through other revenue streams.
Here's how the commercial model typically works. The provider earns money through a combination of paid annual plans (for example £29/year for address services), commission from business banking partners, or minimum spend requirements on the new business account you open. Free company registration may be available through banks that waive the incorporation fee entirely, while several platforms waive their own service fees for company incorporation when bundled with services like a registered office or compliance support.
The three most common "free" models you'll encounter in 2026 are:
Full fee refund when you open a business bank account and spend a set amount (e.g. £100 in 30 days).
£0 company formation bundled with a paid "business account + address" or hassle free compliance service.
Limited-time offers where the £100 fee is fully waived if you activate a partner business account.
Business banking providers may refund the statutory incorporation fee when you open an account, making this the most popular route for new business owners looking to keep startup costs close to zero.
Before you commit, always check the small print. Look for contract length, renewal prices after year one, and any conditions tied to the business bank account - such as identity verification timelines, sector restrictions, or UK residency requirements.
Step-by-Step: How to Register a Limited Company for Free
This section is your practical, chronological guide through the entire company formation process from idea to trading, focused on UK private limited companies (Ltd) in 2026.
Most readers will register online through a company formation agent rather than directly with Companies House, because agents bundle free registration with a business bank account and compliance tools. The agent files with Companies House electronically on your behalf, handling the paperwork so you don't have to navigate government forms.
Typical timelines look like this:
Form completion: 5–15 minutes if you have your business details ready
Provider review: 1–2 hours
Companies House approval: 3–24 working hours
Business account activation: same day in many cases
Before you start, have these ready: company name ideas, a registered office address, director details, shareholder breakdown, and a short description of your company's business activity.
Step 1: Decide if a Limited Company Is Right for You
Before diving into the company registration process, it's worth spending a few minutes confirming that a limited company structure is the right business structure for you. The alternative for most small businesses is operating as a sole trader, and the two work very differently.
A limited company is a separate legal entity. It owns its own assets, enters its own contracts, and - crucially - limited companies protect personal assets from business debts. This limited liability protection means that if the business fails, creditors generally cannot come after your home, car, or personal bank account. As a sole trader, you and the business are legally the same person, so your personal assets are fully at risk.
The tax treatment differs too. Companies pay 19% corporation tax compared to 20–45% income tax for sole traders. Depending on your profit level and how you pay yourself (salary plus dividends), a limited company structure can be significantly more tax-efficient.
There are other practical advantages. Limited companies enhance professional credibility with clients and suppliers - many larger organisations prefer working with an Ltd. Limited companies can also raise capital by selling shares, which is something a sole trader simply cannot do.
When might a sole trader structure be better? If you're testing a low-risk side-hustle, have modest turnover, and want minimal paperwork, sole trader registration is free and requires only HMRC self-assessment enrolment - no Companies House involvement at all.
When does a limited company make more sense? Higher-risk ventures, bigger contracts, plans to bring in investors, or a desire for brand protection all point toward a limited company registered with Companies House.
This article focuses on registering a limited company for free. Keep in mind that you can switch from sole trader to limited company later, and many UK businesses do exactly this once turnover and risk increase.
Non-UK residents can register a UK company without living in the UK. You'll need a UK registered office address (typically via a virtual office address service) and a bank that accepts overseas directors. More on that in the FAQ section below.
It's also worth knowing the broader landscape. Private Limited Companies (Ltd) make up over 95% of UK companies. But other structures exist:
Public Limited Companies (PLC) can sell shares on the stock market
A community interest company focuses on social or environmental goals
A limited liability partnership combines partnership flexibility with limited liability
Companies Limited by Guarantee are often used by non-profits and charities
For most companies and most new founders, a standard private company limited by shares is the right choice - and it's the structure that qualifies for free formation offers.
Step 2: Choose and Check Your Company Name
Your company name is the first thing clients, suppliers, and Companies House will see. Getting it right from the start saves hassle later.
The company name must be unique and not contain sensitive words or expressions. You can't use a name that's already on the company register, and you can't choose something misleading - for example, implying a government connection or using words like "Royal," "Bank," or "Insurance" without special permission.
Most free company formation offers include an instant company name checker that searches Companies House records in real time. Type in your preferred name and you'll see within seconds whether it's available.
Remember that "Limited" or "Ltd" must appear at the end of the name for most private companies limited by shares. So if your brand is "Greenleaf Digital," your registered company name would be "Greenleaf Digital Ltd" or "Greenleaf Digital Limited."
A few practical tips:
Check domain names (.co.uk and .com) at the same time so your company name and online presence match
Search social media handles to avoid confusion
Keep the name short, memorable, and aligned with your brand and what you actually do
The name is only reserved once Companies House accepts the incorporation application, so submitting early helps secure it before a competitor takes it. If you want the fastest possible approval, choose a straightforward name that avoids sensitive words altogether.
Step 3: Gather Your Company Details
Before you open any online form, collect every piece of information you'll need. This prevents you from stopping halfway through to hunt for a document or make a decision under pressure.
Here's what to prepare:
Registered office address: this must be in the UK and appears on the public register. You need a registered office address for your company - it's a legal requirement. Many founders use their residential address, but if privacy matters, a registered office service or virtual office address from a formation agent is a better option.
Director details: full name, date of birth, nationality, residential address, and occupation. A limited company must have at least one director, but there's no strict upper limit. Each company director can also list a separate service address for official correspondence, keeping their personal address off the public record.
Shareholder details and share structure: for example, one director owning 100 ordinary shares of £1 each. Details of all shareholders must be documented at the time of registration.
People with significant control (PSC) information: a person with significant control holds more than 25% of shares or voting rights. For a single-founder company, this is usually the same person as the sole director and shareholder.
A Standard Industrial Classification (SIC) code that describes the business activity, plus a short description of what the company does.
Understanding the key documents helps too. A Memorandum of Association is signed by all initial shareholders to confirm intent to form a company. Articles of Association govern the rules for running a company and are signed by subscribers. Most formation agents use standard model articles, which work perfectly well for straightforward setups.
Let's clarify the address types:
A company's registered office address is the official legal address filed with Companies House. All business correspondence from government bodies goes here.
A service address can be used by company officers to keep their personal address private on the public register.
A trading or business address is where you actually work from, which can be different from the registered office.
Many company formation agents sell virtual office address services that combine registered office, service address, and mail forwarding. These typically cost £39–£99 per year and are popular with home-based businesses.
Identity verification is now legally required at incorporation. Companies House offers registration with mandatory ID checks via GOV.UK One Login, and in 2026 providers must comply with anti-money laundering checks as an authorised corporate service provider (ACSP). You'll typically verify your identity online using a passport or driving licence and proof of address.
Here's an example setup for a typical single-founder tech consultant:
Company name: Bright Code Solutions Ltd
Registered office: Virtual address in London (via formation agent)
Director: Jane Smith (also the sole shareholder)
Shares: 100 ordinary shares at £1 each
PSC: Jane Smith (100% ownership)
SIC code: 62020 (Information technology consultancy activities)
This kind of straightforward setup takes just a few minutes to enter into any online form.
Step 4: Pick a Free Formation Route and Complete the Online Form
The simplest way to register a limited company for free is to use a company formation agent or business banking provider that:
Files directly with Companies House
Covers or refunds the £100 fee
Bundles in a free starter business bank account
Registering a limited company costs £100 at Companies House, but the right provider can eliminate that cost for you. For comparison, Quality Company Formations charges £1.99 plus a £100 Companies House fee - affordable, but not free. Meanwhile, ANNA offers company registration for just £19 instead of £100, and some providers refund the entire fee when you activate a linked business account.
Once you've chosen your route, the on-screen experience is straightforward:
Create an account with email and password
Enter the approved company name and registered office address
Add director, shareholder, and PSC details with prompts and validation
Confirm share structure and statement of capital
Review a summary page before final submission
The website will submit the application to Companies House electronically, typically using the same day incorporation service or standard digital filing. You won't need to touch any government portal yourself - the formation agent handles that.
Double-check the spellings of names and addresses before you hit submit. These appear on the public record and on your official company documents. A typo in your company name or a director's name can cause delays and require formal corrections later.
One reassuring note: you can change some company details later - such as your trading address, SIC code, and even your company name - through standard Companies House filings. So while accuracy matters, a minor oversight at registration won't permanently derail your new company.
Step 5: Wait for Approval and Receive Your Documents
After submission, the waiting game begins - though it's usually a short one.
Realistic 2026 processing times:
Most companies are registered within 1 working day. Most company registrations are processed within one working day.
It typically takes 1–3 days to confirm company registration during busier periods.
Peak periods (end of tax year, for example) can sometimes take slightly longer, but delays beyond a few days are rare for straightforward applications.
Once Companies House approves your application, you will receive a Certificate of Incorporation after registration. This is the document that confirms your company legally exists, showing your company number and the official incorporation date.
The main company documents you'll receive by email:
Certificate of Incorporation (showing company number and date)
Memorandum and Articles of Association
Share certificates for each shareholder
Companies House authentication code (for future online filings, if supplied via email)
You can receive all company documents digitally. Store them in secure cloud storage plus a backup, because banks, investors, and landlords often request them as proof of the company's existence.
Physical printed copies are optional extras that some formation agents offer for a small charge. The digital versions are fully valid and accepted by banks and HMRC.
The official incorporation date printed on the certificate marks the legal birth of your new company and may matter for tax and anniversary filings.
Step 6: Open and Activate Your Free Business Bank Account
Limited companies must have a separate business bank account. Mixing business finances with your personal bank account creates accounting headaches and potential legal issues. If you used a free formation package, opening the linked business account is typically part of the deal - and often the trigger for your £100 refund.
Here's the usual process:
Choose from the provider's list of business banking partners (for example a UK digital bank or high-street bank)
Complete an in-app or online application, uploading ID and company documents
Wait for approval, which can be as quick as minutes for straightforward applications
You need proof of identity to open a business account. A registered office address is required for business account applications. Most banks require a Companies House registration number for account opening, so have your Certificate of Incorporation handy.
Business accounts can be opened within minutes after registration with many modern digital banks. Typical features of a modern free business bank account include:
No monthly fee for the first 12–18 months
Debit Mastercard or Visa, Faster Payments, and international payments
Invoicing tools, receipt scanning, and simple expense cards for team members
The free company incorporation offer may require:
Opening the linked business account within a set timeframe (for example 30 days from incorporation)
Making a minimum qualifying spend or deposit, such as £1 activation or £100 spend within 30 days
Banks still make independent decisions about account approval based on sector, risk profile, and identity checks. Some high-risk industries (crypto, gambling, adult services) may find fewer free business bank options available. If your application is declined, the refund condition may not be met, so check the terms carefully before relying on a "£0 total" promise.
What You Need Before You Register a Company
Think of this as your pre-launch checklist. Having everything ready means you can complete the online form in one sitting without stopping to search for documents.
Pre-registration essentials:
Confirm UK residency or, for non-residents, confirm you can provide a registered uk office address and suitable ID. A registered office address in the UK is required for non-residents.
Prepare personal ID documents (passport, driving licence) and proof of address for each company director and significant shareholder.
Decide the company name, trading name (if different), and at least one SIC code matching planned activities.
Choose a registered office address and, optionally, a separate office address or virtual business address for business correspondence.
Plan share allocations and roles: who will be the company director(s), shareholders, and PSCs.
Think ahead about tax:
Whether you'll need VAT registration soon (for example approaching the £90,000 turnover threshold)
Whether you'll register for PAYE if hiring staff in the first year
A simple single-founder setup is common: one person acts as sole director, sole shareholder (100 ordinary shares at £1 each), and sole PSC. This is perfectly legitimate and covers the vast majority of uk company formation applications.
Non-residents can open a UK business account through specific services designed for overseas founders. If you're not a uk resident, make sure your chosen formation agent and bank both accept non-UK identification before you start the registration process.
Free vs Paid Company Formation: What’s the Difference?
Free registration is ideal for lean startups and new business owners who want to keep launch costs near zero. Paid company formation packages add value for businesses that need extras from day one.
What's typically included in a genuinely free "register a company" package:
Companies House incorporation fee covered or refunded
Digital copies of core company documents (certificate, articles, share certificates)
Access to at least one free or discounted business account
What paid company registration packages usually add:
Registered office and director service address in a central UK location
Business address for marketing materials and client correspondence
First confirmation statement filing and annual hassle free compliance service
VAT and PAYE registration, bookkeeping or accounting support
For context, GoSolo's Company + Account + Address plan costs £199 per year - a reasonable all-in price that bundles formation, banking, and a registered office service. Sole trader registration is free while limited company formation incurs a statutory fee, so if you're comparing raw costs, the Ltd route always involves at least the £100 Companies House fee unless a provider absorbs it.
Many businesses start with the free minimum, then bolt on address services, a London office address, or a company secretary service later as they grow. Base the decision on your budget, privacy needs (do you want your personal address on the public register?), and how much admin you want to delegate in your first year.
Start lean. You can always upgrade. But you can't un-spend money on services you didn't need.
After Registration: Staying Compliant and Growing Your New Company
Getting your company incorporation email is exciting - but it's just the starting line. The real business journey begins with understanding your legal responsibilities in the first 12 months.
Main compliance tasks for a new limited company:
Registration for Corporation Tax is required within three months of starting to do business. HMRC will send you a letter after incorporation, but don't wait - register proactively.
Keep accurate records of income, expenses, and receipts from day one. Your business finances need to be clean and well-documented.
File annual accounts and a confirmation statement with Companies House on time. The confirmation statement costs £50 per year (digital filing) as of 2026.
Maintain up-to-date PSC and company director information on the public register. Companies House requirements have tightened significantly under ECCTA - non-compliance can lead to penalties.
A hassle free compliance service or company secretarial service can handle much of this for you. Typical services include:
Reminders of filing deadlines
Filing changes of directors, addresses, and share structures
Handling the first confirmation statement and routine resolutions
For most companies, integrating your business bank account with accounting software (like Xero, FreeAgent, or QuickBooks) automates bookkeeping and makes VAT and corporation tax calculations far easier. Many free business bank account providers offer direct integrations.
Private Limited Companies (Ltd) make up over 95% of UK companies, and the compliance framework is well-established. Don't be intimidated by it - the system is designed for businesses of all sizes.
First-year operational costs for a small limited company - including accounting, address services, and compliance - typically land between £1,000 and £2,500 depending on complexity. That's the real cost of running a company in the uk beyond the initial formation.
Forming the limited company is step one. Careful record-keeping, timely filings, and smart use of digital tools are what turn a free registration into a lasting, successful business.
FAQs: Free UK Company Registration
Is it really possible to register a UK company for £0?
Yes, it is possible in practice - but only when a provider covers or refunds the £100 Companies House fee. This usually happens in exchange for:
Opening a partner business bank account
Meeting an activation or minimum spend requirement
Or subscribing to a low-cost annual plan that bundles formation
If you go directly to Companies House yourself in 2026, you will pay the standard digital filing fee of £100 and receive no bundled extras like a business account or registered office service. The fee was historically £50 but increased to £100 from 1 February 2026.
Always confirm there are no hidden monthly fees or long contracts attached before relying on a "£0 total cost" marketing message.
Can non-UK residents register a UK limited company for free?
Non-residents can usually register a uk limited company without living in the UK, but they must:
Provide a registered office address within the UK (often via a paid virtual office address service)
Pass identity and anti-money laundering checks remotely
Choose a bank that accepts overseas directors if they want a UK business bank account
Some free registration offers only apply to UK-based directors, so overseas founders should check eligibility and any additional address or mailing fees before starting.
Tax residency and where profits are taxed can be complex for non-residents. Professional tax advice is recommended, especially around corporation tax obligations and double taxation treaties.
Do I have to open a business bank account to get free company registration?
Most free offers are tied to opening a specific business bank account, because the provider uses business banking partners to subsidise the Companies House fee.
While UK law does not explicitly mandate a business bank account for every company type, in practice:
Limited companies are expected to separate business and personal finances
Banks, accountants, and HMRC all strongly recommend distinct business accounts rather than using a personal bank account for company transactions
If you refuse to open the linked account, you should expect to pay the normal Companies House fee or choose a standard paid company registration package instead.
What if my free registration application is rejected by Companies House?
Most simple applications are approved, but rejections can occur due to:
Invalid or restricted company names
Missing or inconsistent director or shareholder information
Problems identified during identity or anti-money laundering checks
Good formation agents will tell you what went wrong and help correct and resubmit the application at no extra cost, especially where they've promised free registration as part of a secure formation service.
Respond quickly to any information requests and choose a straightforward company name if you want the fastest possible approval.
Can I change my company name or details after registering for free?
Yes, many company details can be changed later, including:
Company name (via a special resolution and Companies House form)
Registered office address and director service addresses
Share structure and PSC information
Some changes attract filing fees or require formal resolutions and updated company documents, so it's worth getting the fundamentals as close to final as possible during initial registration.
A hassle free compliance service or company secretary can manage these updates for you - particularly useful if you used a free company formation package and want seamless ongoing admin support as your new business grows.
