How to Register a Limited Company at Companies House

Registering a limited company at Companies House is a straightforward online process that gives your business a separate legal identity from you as the founder. This structure limits your personal liability and is often preferred by early-stage founders and e-commerce sellers who plan to scale or seek investment.

The entire application can usually be completed in under an hour if you have all the information ready, but careful preparation helps avoid common rejections and delays. This guide walks through the exact steps, documents needed and practical tips based on how the system works in practice.

Why choose a limited company over sole trader status

Many first-time UK founders start as sole traders because it requires no formal registration beyond notifying HMRC. However, operating as a limited company creates a distinct legal entity that can enter contracts, hold bank accounts and own assets in its own name. This separation can protect your personal finances if the business faces debts or legal claims.

E-commerce sellers often move to limited status once they begin importing stock, signing supplier contracts or selling on platforms that require business verification. A limited company also tends to look more established to customers, partners and potential investors. Rules, requirements and costs change over time, so always check the latest guidance on GOV.UK before deciding which structure suits your situation.

Documents and information you need before you start

Gather these details in advance to complete the online application without interruption:

• Proposed company name (check availability on Companies House first)
• Registered office address in the UK (this becomes public record)
• Details of all directors (full name, date of birth, nationality, occupation and home address)
• Details of any people with significant control (PSC) – usually the founders who own more than 25% of shares or voting rights
• Share structure – how many shares, classes of shares and who holds them
• Memorandum and articles of association (standard templates are provided during the process)

Directors must usually be at least 16 years old. All addresses are verified against electoral rolls and credit databases, so ensure the information matches official records exactly. Having everything prepared reduces the chance of the application being returned for correction.

Step-by-step registration process at Companies House

1. Go to the Companies House website and select the online incorporation service. You will need a GOV.UK account or be prepared to create one.
2. Search for and reserve your company name. It must end in Limited or Ltd, be unique and not too similar to existing names or trademarks.
3. Enter the registered office address. This can be your home address initially, a serviced office, or an address provided by an incubator if you are accepted into one. Remember it will be publicly visible.
4. Add each director and PSC. Double-check spelling and dates as mismatches cause automatic rejection.
5. Choose your share capital structure. Most early-stage founders use 100 ordinary shares issued at £1 each, split between founders as appropriate. You can change this later.
6. Confirm the standard articles of association or upload custom ones if needed. Most first-time founders use the default model.
7. Pay the incorporation fee and submit. You will receive an immediate reference number.

The system checks for basic errors in real time. Applications submitted during normal business hours are often approved within 24 hours, although it can take longer at busy periods or if manual review is required.

Fees, timelines and what happens after approval

Incorporation fees vary and change periodically, so always check the current amount on the Companies House website before starting. Payment is by debit or credit card during the online process.

Once approved you will receive:

• Certificate of incorporation with your company number
• Digital copies of the memorandum and articles
• Notification that the company is now live on the public register

After incorporation you must register with HMRC for Corporation Tax within a set period – the exact deadline changes so confirm current rules on GOV.UK. You will also need to set up a business bank account, consider VAT registration if your turnover is likely to exceed current thresholds, and arrange for annual accounts and confirmation statements. Timelines for these follow-on tasks are strict; missing them creates penalties that increase over time.

Common pitfalls and how to avoid them

First-time founders often choose a company name that is too similar to an existing trademark or trading name, leading to rejection or later disputes. Search both Companies House and the Intellectual Property Office databases before finalising your choice.

Another frequent error is providing inconsistent address or identity information that fails automatic checks. Use your full official name and ensure the address format matches exactly what is held by credit reference agencies. Using a PO box as the registered office is not permitted.

Many new directors underestimate the ongoing compliance burden. A limited company requires annual confirmation statements, accounts filed on time, and updates to any changes in directors or PSC. Consider these responsibilities before incorporating. Using your home address as the registered office makes it public; if privacy matters, explore virtual office options that comply with Companies House rules.

Finally, do not assume that incorporation automatically handles contracts, terms of sale, GDPR compliance or insurance. These must be arranged separately. For example, your website needs clear terms and conditions and a privacy policy that reflects limited company status.

Next steps after successful registration

With your certificate in hand, open a dedicated business bank account using your new company details. Most high-street and online banks require the certificate, proof of address and director identification. Compare account features for e-commerce sellers such as integration with payment gateways.

Review your contracts and supplier agreements to ensure they are in the company name rather than your personal name. Update any trading platforms, domain registrations and insurance policies. Think about trademark protection for your brand name or logo if you have not already done so.

Keep accurate records from day one. Even simple e-commerce businesses must track income, expenses and stock for Corporation Tax and potential VAT returns. Many founders use accounting software that connects directly to their bank and sales channels.

Support is available for early-stage founders. Organisations such as Loomworks in West Yorkshire offer selected startups free desks, a registered address and mentoring without taking fees or equity. Such resources can help you focus on building the business rather than getting lost in administration.
