Something has shifted on the UK companies register. Application software is now the most common industry among newly formed companies. The founders behind these businesses write code on laptops, meet clients on video calls and ship products through the cloud. For many of them, leasing an office looks like paying for space they will rarely use.
The legal answer is more straightforward than most founders expect. UK limited company formation does not depend on having workspace. It depends on having a registered office address that meets specific rules. This article looks at what the 2026 formation data shows, what the law requires, and what software and AI founders should weigh when they set up a limited company.
A Register Increasingly Shaped by Software
NatWest and Beauhurst’s New Startup Index reports that 402,000 businesses were registered with Companies House in the first half of 2026, a 5.7% fall on the same period in 2025. Yet application software became the UK’s most active startup category, with 28,100 new businesses incorporated, roughly one in every 14 new companies. Beauhurst puts the growth in application software at 40% year on year, enough to overtake restaurants and property development as the most common sector for new companies.
Official Companies House statistics show the wider picture. They record 5,516,377 companies on the register at the end of June 2026, and 192,287 incorporations between April and June alone, or more than 2,000 a day. London remained the leading hub, with more than 136,000 new companies in the half-year.
Beauhurst’s reading is that a fall in incorporations is not the same as a fall in entrepreneurship. The mix of companies being formed is changing, with software and technology taking a growing share. A company whose main costs are people, tools and cloud services has little reason to commit to a lease before it has customers.
What the Law Actually Requires
When founders ask whether they need a physical office, they usually mean two different things: somewhere to work, and somewhere to be registered. GOV.UK’s guidance on setting up a private limited company deals only with the second.
The registered office 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. The address must also be “appropriate”, which the guidance defines in two parts: you, or someone acting on behalf of the company, will be made aware of post delivered there, and the sender can obtain confirmation of delivery.
A Royal Mail PO Box can no longer be used, and that extends to similar services from other companies. If the address belongs to a service provider such as an accountant or solicitor, it must still satisfy every one of these conditions. The guidance warns that a company could be struck off the register if it does not provide a compliant address. The address must also be in place before the company is registered.
Nothing in these formation rules asks a founder to show that they rent or own workspace. The requirement is about where the company can reliably be reached by Companies House, HMRC and others who need to send it an official post.
Privacy and the Public Register
The registered office address is publicly available on the online register. For a founder working from home, this is often the deciding factor. The official advice is direct: if you do not want an address to be public, such as your home, do not use it as the registered office. Two alternatives are suggested: use the address of an accountant or solicitor, with their permission, or appoint an agent who will provide an address.
Companies must also supply a registered email address. Unlike the registered office, this is not published on the public register, though Companies House may use it to contact the company.
The Cost of Cheap Company Formation
Companies House doubled its incorporation fees from February 2026, a change Beauhurst cites as one factor behind the slower formation numbers. The official fee schedule now lists £100 for online incorporation, £100 through software and £124 on paper. Same-day incorporation costs £156.
For founders seeking cheap company formation, the standard online route is the lowest government charge. Speed costs extra, and paper costs extra, so the cheapest approach is simply to prepare everything in advance and file online without a rush. Any spending beyond the statutory fee, whether on an address, accounting or compliance support, is a separate decision based on what the business needs.
Identity Verification Is Now Part of the Process
Anyone planning to register a new company should also account for identity verification. Under the Economic Crime and Corporate Transparency Act 2023, verification became mandatory on 18 November 2025 for company directors and people with significant control. New directors must verify before their appointment is filed, while existing directors are being phased in over twelve months.
The main route is GOV.UK One Login, which is free and can be completed with an existing ID such as a passport or driving licence. Once verified, the individual receives a personal code from Companies House, which is quoted for each role they hold. Verification is also available through an authorised corporate service provider. For software founders who often operate across borders, completing this step early avoids delays at the point of incorporation.
Separating the Legal Question from the Business One
The practical conclusion is that two decisions often get merged when they should be kept apart. The first is legal: which compliant registered office address will the company use, and who will be told when the post arrives there? The second is operational: does the team need desks, meeting rooms or a client-facing base?
A fully remote engineering team may need nothing beyond a compliant registered office. A startup selling to enterprise customers may decide a physical presence helps credibility, but that is a commercial judgement, not a legal requirement for UK limited company formation. At BusinAssist, we see founders make better decisions once they stop treating these as one question.
Conclusion
Software and AI founders are leading UK company formation because starting is inexpensive and the work is portable. The legal foundations are equally portable: a compliant registered office, verified directors and the current incorporation fee. Founders who check the official requirements before they register a new company can keep their fixed costs low while staying fully compliant.
