How to Open a UK Company for Lawyers

For lawyers who want to build an independent practice, consultancy, legal technology business or specialist advisory firm, setting up a UK company can provide a clear corporate structure and a professional platform for growth. But there is an important distinction: forming a company at Companies House is not the same as being authorised to provide regulated legal services.

That distinction matters. A lawyer may be able to incorporate a standard private limited company for certain commercial or advisory activities, while a business providing reserved legal activities to the public may require authorisation from an approved legal regulator.

This guide explains how lawyers can approach UK company formation, what to consider before incorporation, how regulation affects the structure, and what to do after the company is established.

Can a lawyer open a UK limited company?

Yes, a lawyer can own and operate a UK limited company. However, whether the company can provide particular legal services depends on the nature of those services and the applicable regulatory framework. In England and Wales, the Solicitors Regulation Authority (SRA) states that a legal services business generally needs authorisation if it provides reserved legal activities to the public, subject to specific exemptions. Reserved activities include areas such as:

  • Conduct of litigation
  • Rights of audience
  • Certain reserved instrument activities
  • Probate activities
  • Administration of oaths

The position is different for many non-reserved services. A business providing only non-reserved legal services does not necessarily need SRA authorisation, although it may choose to become authorised depending on its business model and the protections it wants to offer clients. This makes the first question more important than simply asking, "How do I register a company?" The better question is: What exactly will the company do, who will own it, and does that activity require regulatory authorisation?

Why lawyers choose a UK company structure

A private company limited by shares can be useful for lawyers who want to build a scalable commercial business. For example, a lawyer might establish a company for:

  • Legal consultancy
  • Contract and commercial advisory services
  • Compliance consultancy
  • Legal operations consulting
  • Legal technology
  • Training and professional education
  • Legal content and research
  • Corporate advisory services
  • Non-reserved legal services
  • A wider professional-services business

A company also separates the business's legal identity from its shareholders. That can make it easier to bring in investors, appoint directors, transfer shares or develop the business beyond the founder. However, limited liability is not a substitute for professional responsibility. Directors remain responsible for the company's management and statutory obligations, while regulated lawyers remain subject to the rules of their relevant professional regulator.

Before choosing a company structure, define the services you intend to sell. This is particularly important for lawyers because two businesses can look almost identical commercially while having very different regulatory requirements. Consider a lawyer who wants to advise technology companies.

Business A provides general commercial strategy, contract-management processes and legal operations consulting without carrying out reserved legal activities. Business B provides litigation services and represents clients in court. Both might call themselves "legal consultancy" businesses, but their regulatory positions are very different. The SRA explains that certain legal services can only be provided to the public by an authorised person or authorised business.

A practical service test

Before incorporation, list every service you expect to sell and divide them into three categories:

  1. Clearly non-regulated commercial services
  2. Non-reserved legal services
  3. Reserved or otherwise regulated services

If the third category applies, investigate the relevant regulator and authorisation requirements before launching. Do not assume that adding "Ltd" to the end of a firm's name gives the company permission to conduct regulated legal work.

Step 2: Choose the appropriate company structure

For many commercial ventures, the obvious starting point is a private company limited by shares. This structure can work well where the founder expects to:

  • Own shares personally
  • Take profits through salary and dividends
  • Bring in additional shareholders
  • Build a team
  • Enter commercial contracts
  • Develop intellectual property
  • Sell the business later

However, a regulated legal practice may require a more specialised structure or authorisation. The SRA recognises different types of authorised firms, including recognised bodies and licensed bodies. A legal practice operating through a limited company is not simply treated as a sole practice; the company itself may need authorisation. For lawyers, therefore, company formation should be treated as a business-structure decision, not merely an administrative exercise.

Step 3: Choose your company name carefully

Your company name is likely to become part of your professional reputation, so choose it with more care than you might for a short-term side business. You should consider:

  • Whether the name is available
  • Whether it is too similar to an existing company
  • Whether it implies a regulated status you do not have
  • Whether it works internationally
  • Whether the corresponding domain name is available
  • Whether the name can support future expansion

Companies House maintains the UK company register, and company information is publicly searchable. If you intend to operate a regulated legal practice, you should also check the relevant regulator's rules concerning firm and trading names.

Step 4: Decide who will own and control the company

Ownership deserves particular attention when lawyers establish a company with colleagues, consultants or investors. You need to establish:

  • Who the shareholders are
  • How many shares each shareholder owns
  • Who the directors are
  • Who has voting control
  • Whether anyone is a person with significant control (PSC)
  • What happens if a shareholder leaves
  • Whether shares can be transferred freely
  • How new investors could be admitted

Companies House records information about directors, PSCs and shareholding arrangements. For a two-founder law consultancy, for example, simply issuing 50 shares to each founder may appear straightforward. But a shareholders' agreement can become important if one founder later wants to leave, reduce their involvement or sell their shares. A good corporate structure anticipates difficult scenarios before they happen.

Step 5: Prepare the information needed for incorporation

When incorporating a UK company, you will generally need to provide information including:

  • Proposed company name
  • Registered office
  • Directors
  • Shareholders
  • Share capital
  • Persons with significant control
  • Company constitution
  • Intended business activities

Companies House provides an online incorporation service for private companies limited by shares using model articles, while alternative incorporation arrangements are available where appropriate. Company directors and other relevant individuals are also subject to identity-verification requirements as part of Companies House reforms. This is especially relevant to international founders and lawyers establishing UK businesses remotely.

Step 6: Choose an appropriate registered office

Every UK company needs an appropriate registered office address. The registered office is the official address for statutory communications. It is not necessarily the same as the address from which you actually work. If you use your home address, remember that information filed at Companies House can be publicly accessible.

For lawyers working from home or operating internationally, a professional registered office service can therefore be worth considering, provided it meets Companies House requirements. The address must be appropriate for receiving official documents, and current Companies House guidance sets requirements around the suitability of registered office addresses.

Step 7: Select the right SIC code

Your company will need to state its principal business activity using a Standard Industrial Classification (SIC) code. The code should accurately reflect what the company does. A lawyer running a legal consultancy should not select a random code simply because it appears broadly related to professional services. If the company later changes its activities, its SIC information may also need updating. For businesses combining legal work with technology, education, consultancy or other services, choosing appropriate SIC codes deserves particular attention.

Step 8: Incorporate the company with Companies House

Once the structure and information are ready, the company can be incorporated with Companies House. Companies House is responsible for incorporating and maintaining the register of UK companies.

For a straightforward private limited company, online incorporation is generally the simplest route. Once incorporation is completed, the company receives its company registration number and becomes a separate legal entity. But incorporation is only the beginning. A lawyer should not treat the Companies House certificate as evidence that the business is authorised to provide every type of legal service.

Regulation: the issue lawyers must not overlook

This is the biggest difference between opening a normal consultancy and opening a legal practice.

England and Wales

The SRA regulates solicitors and law firms in England and Wales. If your company will provide reserved legal services to the public, you need to determine whether it must obtain SRA authorisation or authorisation from another approved regulator.

The SRA also recognises licensed bodies, sometimes referred to as alternative business structures (ABS). These can have different ownership and management arrangements from traditional lawyer-only practices, subject to the relevant regulatory requirements. Some SRA-authorised licensed bodies operate as limited companies, demonstrating that incorporation and legal regulation can coexist but the regulatory authorisation is an additional layer.

Scotland and Northern Ireland

The regulatory position is different in Scotland and Northern Ireland. A lawyer establishing a practice there should identify the relevant professional regulator and applicable rules before deciding on the final structure. This is particularly important for firms intending to operate across multiple UK jurisdictions.

Step 9: Set up business banking and accounting

After incorporation, establish a dedicated business bank account. Do not mix company money with personal funds simply because you are the sole shareholder. You should also put basic accounting systems in place for:

  • Invoices
  • Expenses
  • Payroll
  • Corporation Tax
  • VAT where applicable
  • Dividends
  • Client payments
  • Management accounts
  • Financial records

A lawyer may understand financial documentation better than many founders, but that does not eliminate the need for proper company accounting. If the company is regulated, additional requirements may apply to client money and financial controls. These should be considered separately from ordinary business banking.

Step 10: Put professional protection in place

Insurance is another area where legal businesses require careful planning. Depending on the services offered and regulatory status, you may need appropriate professional indemnity insurance and other cover.

For regulated firms, professional indemnity and client-protection requirements can form part of the applicable regulatory framework. The SRA, for example, highlights insurance and client protections for authorised firms. A general business insurance policy should not automatically be assumed to satisfy professional or regulatory requirements.

Step 11: Establish contracts, privacy and compliance systems

Before taking on clients, create a clear operational framework. Depending on your business, this could include:

  • Client engagement letters
  • Terms of business
  • Privacy notice
  • Data protection procedures
  • Complaints procedure
  • Conflict-checking process
  • Client onboarding procedures
  • Record retention policies
  • Information-security controls
  • Anti-money-laundering procedures where applicable

For a modern legal consultancy, these systems are not administrative decoration. They influence how quickly you can onboard clients and how confidently you can scale.

What about lawyers based outside the UK?

A UK company can be attractive to international founders who want a UK corporate vehicle. However, incorporation does not automatically give a foreign lawyer the right to practise UK law, live in the UK, provide regulated services, or avoid tax obligations in their country of residence. International founders should consider:

  • Where the business is actually managed
  • Where services are physically performed
  • UK tax obligations
  • Overseas tax residency
  • Permanent establishment risks
  • Professional licensing
  • Immigration requirements
  • Banking requirements
  • Client-location rules

A UK company can be commercially useful, but it should form part of a wider cross-border structure rather than being treated as a shortcut around local regulation. IncorpUK can be relevant in this context as a UK company formation and management platform for global founders, but international lawyers should still obtain appropriate legal and tax advice for their individual circumstances.

Common mistakes lawyers make when setting up a company

Mistake 1: Incorporating before checking regulation

This can create an awkward situation where the company exists but cannot lawfully provide the intended services.

Mistake 2: Confusing a solicitor's qualification with company authorisation

Being personally qualified does not necessarily mean that a separate corporate entity is authorised to provide regulated services.

Mistake 3: Ignoring ownership restrictions

Bringing in non-lawyer investors or business partners may have regulatory implications depending on the firm's structure and activities.

Mistake 4: Treating Companies House compliance as the whole job

A company has ongoing obligations, including accounts, confirmation statements and maintaining accurate company information. Companies House makes company information publicly available and expects it to remain up to date.

Mistake 5: Using a generic consultancy structure for a regulated practice

A structure that works perfectly for a marketing consultancy may be unsuitable for a firm carrying out reserved legal activities.

A practical setup checklist for lawyers

Before launch, work through this checklist:

  • Define exactly what services the business will provide
  • Identify whether any services are reserved or otherwise regulated
  • Confirm the relevant professional regulator
  • Choose the appropriate corporate structure
  • Decide ownership and voting arrangements
  • Choose a compliant company name
  • Select suitable SIC code(s)
  • Arrange an appropriate registered office
  • Complete Companies House incorporation
  • Complete required identity verification
  • Establish business banking
  • Set up accounting and tax processes
  • Review professional indemnity insurance
  • Prepare client contracts
  • Establish data-protection procedures
  • Establish conflicts and client-onboarding procedures
  • Check ongoing regulatory obligations
  • Create a calendar for Companies House and tax deadlines

Frequently Asked Questions

Can a solicitor set up a limited company in the UK?

Yes. A solicitor can establish a UK limited company, but the company may require separate regulatory authorisation if it will provide regulated legal services. The structure should therefore be considered alongside the firm's intended activities.

It can provide certain legal services, but regulated or reserved activities may require authorisation. The requirements depend on the services, jurisdiction and regulatory framework.

Does a law firm have to be authorised by the SRA?

Not every business offering legal-related services requires SRA authorisation. The SRA states that businesses providing reserved legal activities to the public generally need authorisation, while businesses providing only non-reserved legal services do not necessarily need it.

Potentially, but ownership rules depend on the firm's regulatory structure. Alternative business structures can permit certain non-lawyer ownership arrangements, subject to regulatory requirements. This should be established before shares are issued.

Can a lawyer outside the UK open a UK company?

Yes, subject to the company's incorporation requirements. However, owning a UK company does not automatically give the founder the right to practise law in the UK or avoid tax, immigration or professional-regulation requirements in another country.

What SIC code should a lawyer use?

The appropriate SIC code depends on the company's actual business activities. A legal practice, legal consultancy and wider professional-services business may require different classifications. The code should accurately describe the company's activities.

Does a lawyer need a business bank account?

A limited company should maintain separate company finances. A dedicated business bank account makes it easier to distinguish company transactions from personal finances and maintain reliable accounting records.

Does a law firm need professional indemnity insurance?

Requirements depend on the firm's activities and regulatory status. Regulated legal practices may be subject to specific insurance requirements, so firms should check the rules of their regulator rather than relying on ordinary commercial insurance.

Is incorporating a company enough to start a law firm?

No. Incorporation creates the corporate entity, but it does not by itself satisfy professional or regulatory requirements. Lawyers intending to operate a regulated practice must consider authorisation, insurance, client-money rules, professional conduct and other applicable obligations.

Conclusion

Opening a UK company for a lawyer can be straightforward from a corporate-registration perspective, but the real work is deciding what the company is legally and commercially intended to do. For a legal consultant providing non-reserved services, a standard private limited company may provide a practical foundation for building a professional business. For a regulated legal practice, the analysis goes further: the firm's ownership, management, activities, insurance and regulatory authorisation all need to fit together.

The safest approach is to work backwards from the services you intend to provide. Define the activities, identify the regulatory requirements, choose the appropriate structure, incorporate the company, and then build the accounting, contractual, compliance and operational systems around it.

For lawyers, the strongest company structure is not necessarily the simplest one to register. It is the one that supports the firm's commercial ambitions without creating a regulatory problem later.
