How to Set Up a UK PLC (Public Limited Company) in 2026

UK PLC company formation gives you a public limited company that can offer its shares to the public, raise money from a wide investor base and, later, seek a listing on a stock exchange. It keeps limited liability for its shareholders, pays the same Corporation Tax as any UK company, and carries a name that banks, suppliers and tender panels take seriously.

The hard part is the rulebook. A PLC needs at least £50,000 of allotted share capital with a quarter paid up, two directors, a qualified company secretary and a trading certificate before it can do business or borrow. It also files accounts faster, needs a full audit every year and must hold an AGM.

This is where we come in. We form the PLC ourselves and handle the whole setup: the directors and secretary, identity checks, the articles, the capital, the filing and the trading certificate. You deal with one team, and we quote the full cost in writing before you pay.

Why Set Up a PLC in the UK

A PLC is the only kind of UK company that can offer its shares to the public, and UK PLC company formation is how you get that right from day one. That single right is the main reason to choose it, and it brings a few others with it.

Offer Shares to the Public

A private limited company is barred from offering its shares to the public under section 755 of the Companies Act 2006. A PLC is not. It can invite investment from anyone, which opens up crowdfunding rounds, public offers and wider share ownership.

A Path to a Stock Market Listing

UK companies listed on the London Stock Exchange's Main Market or on AIM are public companies. Being a PLC does not list you, because admission needs FCA approval for the Main Market or a nominated adviser on AIM, but it is the first step on that path.

Credibility With Banks, Suppliers and Tenders

The letters "plc" tell a counterparty that the company has at least £50,000 of capital, a qualified secretary and audited accounts. Some public tenders, large suppliers and investors are more comfortable dealing with a PLC for that reason.

Easier Share Transfers and Investor Exits

Many private company articles restrict who shareholders can sell to. Read more about the benefits of setting up a company in the UK in general. A PLC is built for a wider and changing shareholder base, which makes it easier for investors to buy in and sell out.

The Same Corporation Tax as a Private Company

A PLC pays Corporation Tax at 19% on profits up to £50,000 and 25% above £250,000, with marginal relief in between, exactly like a private company. Its dividends carry no UK withholding tax.

PLC vs Private Limited Company in the UK

For most founders, a private limited company is the better choice. A PLC only earns its extra cost and rules when you need to offer shares to the public or prepare for a listing, which is the real test for UK PLC company formation.

Read the table as a list of costs. Each extra rule for a PLC, the capital, the secretary, the audit and the faster deadlines, costs money every year. If you will not offer shares to the public, those costs buy you very little.

When a Private Company Is Enough

Most start-ups, holding companies and trading companies raise money privately, from founders, angels or funds, and a private limited company does that perfectly well. You can re-register it as a PLC later if you need to. Our UK company registration guide covers the private company route.

A Public Company Is Not a Listed Company

Being a PLC gives the right to offer shares to the public. Listing is a separate, much larger project with its own rules, advisers and costs. Many PLCs are never listed at all.

UK PLC Company Registration Requirements

UK PLC company registration has five requirements that a private company does not face, plus the rules every UK company meets. Plan all of them before you file.

£50,000 Share Capital, a Quarter Paid Up

A PLC must have allotted share capital of at least £50,000, or €57,100 if the capital is in euros, under section 763 of the Companies Act 2006. It cannot mix the two. Each share must be paid up to at least a quarter of its nominal value plus the whole of any premium, so at least £12,500 must actually be paid in. That money is the company's capital, not a fee, and it stays in the business.

Two Directors and a Qualified Company Secretary

A PLC needs at least two directors, and at least one must be a real person. It also needs a company secretary who has the knowledge and experience for the role and a recognised background, such as three of the last five years as a PLC secretary, membership of a professional accountancy or governance body, or qualification as a UK barrister or solicitor.

The PLC Name

The name must end with "public limited company" or "plc". A Welsh company can use "cwmni cyfyngedig cyhoeddus" or "c.c.c.". The usual rules apply too: it cannot be the same as an existing name, and some words need approval. Check the UK company name before you prepare anything else.

Registered Office and Identity Verification

Like every UK company, a PLC needs an appropriate registered office in the part of the UK where it is registered and a registered email address. Our guide to UK registered office address rules explains what counts, and most PLCs register in England and Wales. Since 18 November 2025, every director and every person with significant control must verify their identity before the company can be registered.

The Trading Certificate

A company formed as a PLC cannot do business or borrow until Companies House issues a trading certificate under section 761. You apply on form SH50 once the minimum capital is allotted and paid up, and there is no Companies House fee for it. Trading without one is an offence by the company and every officer in default, and the directors can be personally liable if the company fails to meet its obligations.

How to Set Up a PLC in the UK

To set up a PLC in the UK, you plan the capital and the people first, then register the company, then pay up the capital and get the trading certificate. Knowing how to set up a PLC in the UK mostly means getting this order right.

Plan the Capital and the Shareholders

The first step in how to set up a PLC in the UK is the money. Decide how the £50,000 or more will be split between shareholders, how much will be paid up at the start, and whether any shares will be issued for something other than cash. A share issue for non-cash assets in a PLC usually needs an independent valuation.

Appoint the Directors and the Secretary

Choose at least two directors and a qualified company secretary. Confirm the secretary's qualifications in writing, because Companies House records the appointment and investors will check it.

Verify Every Director and PSC

Each director and each person with more than 25% of the shares or votes verifies their identity and gets a personal code. It works online from any country with a passport.

Prepare the Articles and Statement of Capital

A PLC usually adopts model articles for public companies, adapted where needed. The statement of capital shows the shares, their classes and how much is paid on each.

File the Application With Companies House

The GOV.UK online service only covers private companies with model articles, so a new PLC is usually registered on paper form IN01 for £124. Paper applications take about 8 to 10 days to process, and you then receive the certificate of incorporation and the company number. This is the slowest part of PLC registration in the UK.

Pay Up the Capital and Apply for the Trading Certificate

Once the company is registered, the shareholders pay at least a quarter of the nominal value of their shares plus any premium. Then you apply for the trading certificate on form SH50. Only when it is issued can the PLC trade or borrow.

Re-Registering a Private Company as a PLC

You do not have to start a PLC from scratch. An existing private limited company can re-register as a public company, which is how many growing companies make the move once they are ready to offer shares more widely.

What Re-Registration Needs

The shareholders pass a special resolution to re-register, and the company must meet the PLC capital rules. It needs a balance sheet dated no more than seven months before the application, an unqualified auditor's report on it, and an auditor's statement that net assets were not less than the called-up share capital plus undistributable reserves. Shares allotted for non-cash assets between the balance sheet date and the resolution need a valuation.

Filing Form RR01

The application is made on form RR01, on paper, for £124, with the amended articles and, if the company has no secretary yet, a statement of the proposed secretary. A company that re-registers does not need a separate trading certificate.

When Re-Registration Makes Sense

Re-registration suits a company with a trading history, audited accounts and investors ready to come in. It avoids moving contracts, bank accounts and staff to a new company. Our guide to setting up a UK holding company covers another way groups restructure before a raise.

Documents Needed for UK PLC Company Registration

UK PLC company registration needs more planning than paperwork. Companies House does not ask for certified passport copies, because identity is checked through verification, but it needs exact details of the people, the capital and the secretary.

Details for Every Director, Shareholder and PSC

Full legal name, date of birth, nationality, country of residence, a service address that will be public, a home address that is kept private, and the personal code from identity verification. For the secretary, the same details and a record of the qualification that meets section 273.

Company Details for the Application

• Company name: Ending in "public limited company" or "plc".
• Registered office: In the part of the UK where the company is registered.
• Registered email address: For Companies House contact only.
• Statement of capital: At least £50,000 allotted, with the amount paid on each share.
• Articles of association: Model articles for public companies or your own version.
• SIC code: At least one, describing the main activity.

Evidence for the Capital and the Bank

Keep proof that the capital was paid in, such as a bank statement, because the trading certificate application confirms it. A bank or payment provider will also ask for the certificate of incorporation, the trading certificate, the articles, a passport and proof of address for each owner, a business description and where the money came from.

Cost of Setting Up a PLC in the UK in 2026

The cost of setting up a PLC in the UK is higher than for a private company, and most of the difference comes after formation. Public limited company formation in the UK itself is not the expensive part. We quote a PLC formation in writing with your setup, because the secretary, the capital and the trading certificate change the work. The quote includes the £124 Companies House filing, and a standard private limited company starts from €350 by comparison.

What Moves the Cost of a UK PLC

The audit is usually the largest yearly cost, and it grows with the company's size and complexity. The secretary is the second. The capital is not a cost, but at least £12,500 has to be paid in and stay in the company. A PLC preparing for a public offer or a listing adds legal, advisory and exchange fees that are far larger than anything on this table. Read more: the cost of setting up a UK company.

How Long UK PLC Company Formation Takes

UK PLC company formation takes longer than a private company, mainly because the application goes on paper and the trading certificate comes after registration. Our guide on how long it takes to register a UK company compares the routes. With every document ready, plan for about three weeks from start to trading.

What Adds Days

A secretary without the right qualifications, a statement of capital that does not add up, a name that clashes and a missing identity code are the usual causes. Each one means a rejected paper form and another wait.

Running a PLC After Registration

A PLC carries more duties than a private company, and the penalties for missing them are higher. Put every date in a calendar on the day the company is registered.

Accounts and the Audit

A PLC files its accounts with Companies House six months after the year end, three months sooner than a private company, and it cannot use the small company audit exemption. The late filing penalties are £750 up to one month late, £1,500 up to three months, £3,000 up to six months and £7,500 after that.

The Annual General Meeting

A PLC must hold an AGM within six months of the end of each financial year. The shareholders receive the accounts, can question the directors and usually vote on reappointing the auditor.

Tax Residence and Corporation Tax

A PLC incorporated in the UK is UK tax resident by default and pays Corporation Tax on its worldwide profits. If its directors run it from another country, that country may also treat it as resident. Read whether a UK company is tax resident.

Business Banking for a UK PLC

A PLC needs its account open before the capital is paid in, and many founders abroad get stuck here. UK high street banks usually want a director who lives in the UK. Our banking partners open accounts for UK companies owned and run from anywhere, in days and remotely.

Why UK Banks Are Slow With a New PLC

A new PLC has no trading history and often several shareholders, so the bank traces every owner above 25% and asks where the capital came from. With directors abroad, most high street banks refuse at the residence check.

The Faster Route Through Our Banking Partners

Our partners are licensed electronic money institutions that onboard new UK companies, PLCs included, with owners anywhere. We prepare the file with the certificate of incorporation, the capital evidence and the ownership chart.

UK PLC vs Ireland, Cyprus and Malta

Founders who want public-company status sometimes compare public limited company formation in the UK with an EU company. Ireland, Cyprus and Malta all have their own public company forms with their own capital rules. The main difference is tax and EU access, so the table compares the jurisdictions themselves.

A UK PLC gives you access to London's capital markets, which none of the others match. An EU company makes sense when your investors, customers or a licence need one.

UK vs Ireland

An Irish company pays 12.5% on trading profit and sits inside the EU, and Ireland has its own public limited company form. It needs a company secretary and, if no director lives in the European Economic Area, a Section 137 bond. See our Ireland company formation guide.

UK vs Cyprus

Cyprus charges a flat 15% on company profit from 1 January 2026, and every Cyprus company needs an audit. It is mainly used for holding companies with a wide treaty network. Read about holding company formation in Cyprus.

UK vs Malta

Malta taxes company profit at 35%, then refunds six sevenths to shareholders after a dividend, which brings the effective rate to about 5%. Every Malta company needs an audit. Read how to set up a Malta holding company.

Who a UK PLC Is Wrong For

A PLC is the wrong choice for most small businesses. In these cases, a private limited company saves money every year.

Start-Ups Raising Money Privately

Founders, angels and venture funds invest in private limited companies every day. If you will not offer shares to the public, a PLC adds cost without adding anything you need.

Founders Who Cannot Put Up the Capital

At least £12,500 must be paid in before the PLC can trade. If that money is needed for the business elsewhere, form a private company now and re-register later.

Companies That Want Light Compliance

A PLC files faster, needs an audit and an AGM, and pays higher late filing penalties. If you want the lightest possible compliance, choose a private company.

Common Mistakes When Setting Up a UK PLC

Most problems with a new PLC come from treating it like a private company. These are the mistakes we see most often.

Trading Before the Trading Certificate

A newly formed PLC cannot sign contracts for business or borrow until the trading certificate is issued. Doing so is an offence, and the directors can become personally liable.

Appointing a Secretary Without the Qualifications

The Act sets out who can be a PLC secretary. An unqualified appointment is a breach that investors, auditors and banks will spot.

Forgetting the Six-Month Accounts Deadline

Owners used to private companies plan for nine months and miss the PLC deadline of six. The late filing penalty for a public company starts at £750.

Confusing a PLC With a Listing

Forming a PLC does not list the company or raise any money. A public offer or a listing is a separate project with its own advisers and rules.

Bottom Line

A UK PLC is the only company that can offer its shares to the public, and it is the first step towards a listing. Public limited company formation in the UK is quick once the capital and the secretary are in place. It also needs £50,000 of capital with a quarter paid up, two directors, a qualified secretary, a trading certificate, an audit, an AGM and accounts within six months. If you need public investment, that is a fair price. If you do not, a private limited company does the job for far less. We form either, and we quote a PLC in full, in writing, before you pay.
