Britain's company register keeps growing, even as the rules around it tighten. For anyone planning to start a UK company, the numbers are encouraging and the small print matters more than ever.
Somewhere in the UK, a new company is registered roughly every 40 seconds. Official figures from Companies House show 815,277 incorporations in the financial year ending March 2026, a rise of 1.67% on the year before. Spread across 8,760 hours, that works out at about 93 new companies every hour, around the clock, every day of the year.
The register itself now holds 5,516,377 companies, according to the latest GOV.UK statistics, which cover the period to the end of June 2026. The average company on the register is 9.2 years old, so this is a mature population of businesses being topped up by a steady stream of newcomers.
Is the boom still booming?
The headline numbers are strong, but the picture has become more nuanced this year. Companies House recorded 204,612 incorporations between January and March 2026, up 10.67% on the previous quarter. Analysis published by NatWest and Beauhurst, and reported by SME Web, shows incorporations easing to around 195,000 in the second quarter after peaking at 219,000 in the third quarter of 2025.
The report points to two regulatory changes as likely contributors: mandatory identity verification for directors and persons with significant control, which began on 18 November 2025, and a doubling of Companies House incorporation fees from 1 February 2026. Even so, the same report puts the number of active UK companies at a record 5.66 million, with London still accounting for the largest share of new companies and Scotland and the East Midlands showing the fastest growth in start-up activity.
In other words, the appetite to start a UK company has not gone away. It has simply become a little more deliberate.
What it actually costs to set up
The phrase "cheap company formation" gets used a lot, so it helps to start with what the state charges. According to the official Companies House fee schedule, registering a limited company online costs £100, or £124 on paper. A same-day incorporation through software costs £156. The annual confirmation statement, which confirms that the details held on the register are correct, costs £50 online.
That £100 fee is the statutory floor. Everything else, such as an accountant, bank account, insurance or a business address, is a separate choice. The most economical route is rarely the one with the lowest headline price. It is the one that gets the basics right first time, because a rejected or non-compliant application costs both money and momentum.
The legal basics have not changed
The appeal of UK limited company formation is largely structural. A limited company is legally separate from the people who own it, and GOV.UK explains that owners are responsible for business debts only up to the value of their investment. That protection, together with access to business loans and investment, is why most businesses choose to register either as a limited company or as a sole trader.
The requirements for getting started are modest:
- at least one director, who must be an individual rather than another company
- at least one shareholder, who can also be a director
- identification of any person with significant control, such as anyone holding more than 25% of the shares or voting rights
- a registered office address and a registered email address
- the company's founding documents, including its articles of association and, for a company limited by shares, a statement of capital
A company secretary is optional, and a newly registered company does not have to start trading immediately. GOV.UK confirms that a company can be left dormant.
Identity verification is now part of the process
The biggest practical change for new founders is identity verification. From 18 November 2025 it became a legal requirement for directors and persons with significant control. Companies House describes that date as the start of a 12-month transition period rather than a deadline, giving existing companies time to make sure everyone has verified by their due date.
Most people can verify online through GOV.UK One Login using a biometric passport from any country, a UK photo driving licence, or a UK biometric residence permit or card. Those without suitable photo ID may be able to verify at a Post Office or with bank details, and an Authorised Corporate Service Provider, such as an accountant or solicitor, can also verify identity on someone's behalf. Companies House also warns founders never to sell or lend their identity to anyone setting up a company, because the legal responsibility stays with them.
For overseas founders, the biometric passport route means verification need not involve a trip to the UK, though it is worth completing early so it does not hold up an application.
The registered office: where many applications go wrong
Every company must provide a registered office address, and since 4 March 2024 it has had to be an "appropriate address". GOV.UK says the address must be a physical address in the UK, in the same country the company is registered in. A company registered in Scotland, for example, needs a Scottish address.
"Appropriate" has a specific meaning. Post sent to the address must come to the attention of someone acting for the company, and the sender must be able to obtain confirmation of delivery. Royal Mail PO Boxes and similar services no longer qualify. If a company uses a service provider's address, such as an accountant's or a solicitor's, that address must meet all of the same requirements. A company that fails to maintain a compliant registered office could be struck off the register.
One point catches many first-time founders out: the registered office address is published on the public register. Anyone who does not want their home address visible should not use it. GOV.UK suggests using another address, with the owner's permission, or appointing an agent who provides one. The registered email address, by contrast, is not published.
Where a UK Virtual Office fits
This is why a UK Virtual Office has become a popular choice for freelancers, remote-first teams and overseas founders. The registered office does not have to be the place where the work happens. Wikipedia's overview of private limited companies notes that the registered office does not need to be the usual business address and is often the address of a company's lawyers or accountants. For a founder working from home or from another country, a virtual address can keep personal details off the public record while giving an official post somewhere to land.
The test is the same one the government applies to everyone: is the address real, is the post actually received and acted on, and can delivery be confirmed? Some founders go straight to a specialist such as BusinAssist, while others ask their accountant or solicitor, but whichever route they take, the deciding factor should be whether the arrangement meets the "appropriate address" requirements rather than how little it costs. Founders should confirm in writing that someone will handle and forward post, and check that they have permission to use the address.
What the boom means for founders
The figures suggest three practical takeaways for anyone planning to start a UK company this year:
Competition is real, but so is demand. With more than 5.5 million companies on the register, standing out depends on execution, not just incorporation. Registration costs very little compared with the work of building a customer base.
Compliance is now front-loaded. Identity verification and the appropriate-address rule mean the paperwork has to be right at the start. Sorting out verification, a compliant registered office and a monitored email address before applying avoids delays.
Low cost does not mean low standards. The £100 filing fee is modest, but the confirmation statement, annual accounts and Corporation Tax obligations follow every year. Budgeting for the ongoing costs matters as much as the formation fee.
The UK remains one of the easiest places in the world to form a company, with a clear process, transparent public fees and legal protections that founders understand. The 90-an-hour pace shows that people are still choosing it. For those about to join them, the rules are clearer than ever, and the founders who read them first tend to start the fastest.
