How Much Does It Cost to Register a Business in the UK?

Last Updated on August 14, 2026 by Joy Kyalo

Most people asking how much it costs to register a business are expecting a single number. The reality is slightly different. While the Companies House registration fee is currently £100, that’s only one part of getting a business ready to trade.

Depending on your setup, you may also need a registered office address, tax registrations, banking, and ongoing compliance support. Here’s what opening a business in the UK actually costs.

The basic cost to register a UK limited company

A private limited company formed through Companies House is the most popular way of incorporating your company digitally. The current charge for a digital incorporation of a company is £100. The fee applies to the registration itself only – no other charges. Before the process can proceed further, you will need a name, address, a director and the description of the business activity.

Paper forms cost more, and there is an extra charge for same-day incorporation. An online incorporation is the default option for most founders.

There is another important piece of information that you should know. Starting from November 2025, all newly appointed directors, people with significant control and LLP members will have to verify their identities at the moment of appointment. The new procedure will be integrated into the incorporation process. The choice of the route, either GOV.UK One Login or authorized service providers, impacts the costs.

Company registration costs by business structure

Not every business needs to go through Companies House. The right structure changes both the upfront cost and the admin that follows.

Sole Trader:

There is no Companies House charge for a sole trader. This means that you register yourself for Self-Assessment with HMRC and declare your income on the annual tax return form. Generally, there is no registration fee for this procedure. This is one of the most cost-effective ways to set up your own business; however, the cost is high, and you need to understand it: you and your company will be considered one entity under the law. If your company gets into debt, you are personally responsible for it.

Ordinary partnership:

A traditional partnership also doesn’t normally require Companies House registration. Partners register with HMRC and each handles their own tax. A written partnership agreement is advisable regardless of how well the partners know each other, and having one drafted properly adds to your setup costs.

Limited company:

A private limited company gives you a separate legal entity. It carries the £100 incorporation fee and ongoing compliance obligations, but it also limits personal liability and tends to be taken more seriously by clients, banks and suppliers.

Limited liability partnership:

A limited liability partnership is registered at Companies House and has its own filing requirements. It suits professional practices and businesses with multiple active members, but it isn’t simply a cheaper or simpler version of a limited company. Get proper advice before choosing this route.

The costs that sit around incorporation

This is where the realistic budget starts to look different from the headline fee.

Every limited company needs a registered office address in the UK. Since March 2024, companies must provide a physical UK address as their registered office, not just a PO box. That address appears on the public register and receives official statutory correspondence from Companies House and HMRC.

Using one’s own residential address as the founder’s address is acceptable from the legal point of view but it will become public information. In case you want it to be kept confidential or if you are an overseas founder without a UK address, using a registered office is the right choice. BusinAssist offers registered office addresses with mail services included in order to receive the statutory post in a timely manner. The price depends on the region and the extent of mail services provided.

Directors also need to provide an address for the public register. A service address can be used instead of a residential one, keeping personal details off the public record. That’s another cost worth factoring in if privacy matters.

VAT, PAYE and other tax registrations

There is no government charge for VAT registration at HMRC. However, it becomes mandatory when taxable turnover exceeds the present limit, although sometimes, it is voluntarily registered prior to exceeding the limit. The decision to voluntarily register depends on your customers, expenses, and cash flow. If you are running a business which deals with companies registered for VAT, then it might be appropriate for you to voluntarily register.

Registering as an employer for PAYE is also free, though payroll software, pension duties and payslip obligations create ongoing costs. If you’re paying yourself as a director through payroll, that registration needs to be in place before the first payment goes out.

Banking, phone and trading presence

While setting up a bank account for business may be free of cost at entry level, charges related to transactions, international payments and cash management could add to the expense. International entrepreneurs are likely to go through some extra verification processes while setting up the account. You should be prepared with an accurate account of your business idea, ownership and transaction volume.

A UK phone number, a virtual office in UK and post handling services can be just as important as the company registration process in case of a client-oriented business, providing credibility without the overhead cost of renting a physical office space. The packages provided by BusinAssist include all such services.

Ongoing costs after registration

The incorporation fee is a one-off. Staying in good standing requires an annual budget.

The cost of the Confirmation Statement digital filing is £50 per year. This verifies the accuracy of certain information about the company, such as directors, shareholders, people with significant control and the registered office address. This is a compulsory requirement, and failure to file the document within the specified period can result in a fine or, in some cases, even strike the company off the registry.

The annual accounts, Corporation Tax returns, and statutory registers are part of the process as well. The cost varies greatly depending on the complexity of the work. There is a great difference between the preparation of accounts for a dormant company and a VAT-registered one that has employees, international customers and shareholders.

Name changes, share restructures and director or registered office changes may carry additional filing requirements. Some are free; others involve a service charge if you’re using a provider.

A realistic first-year budget

When setting up a simple UK limited company in which the founder has an appropriate registered office address, the first-year fee paid to the government amounts to £100. However, when a professional registered office, director service address, and assistance in setting up the company are added, the cost of setting up the business will increase, and the final cost will vary depending on the service provider.

Overseas founders should budget more broadly. The practical requirement isn’t just a company number. It’s a reliable UK address, the ability to receive official correspondence, completed tax registrations, a professional contact point and filings kept on track after launch.

Choosing the lowest cost without creating risk

The cheapest formation route isn’t automatically the best value. Registering with incomplete information, using an unsuitable address or missing tax and filing deadlines can cost more to fix than professional support would have cost at the start.

A more practical way to do this is to segregate the mandatory charges from the options for the running of the company. Make the payment to the Companies House, pick the correct format, then you can add the services that will offer privacy and help your business run smoothly. BusinAssist offers all these services under one umbrella.

Registration costs are only part of the decision. The businesses that avoid problems later are usually the ones that budget for compliance, tax obligations, and administration from the beginning rather than treating them as future issues.

Get registered correctly, give the company a dependable base to operate from, and the admin side of the business largely takes care of itself.
