The UK legal sector is evolving rapidly, with more solicitors choosing to launch their own consultancies rather than staying in traditional practice. Whether you're leaving a law firm, retiring from partnership, or simply seeking more autonomy, starting a legal consultancy can be incredibly rewarding—if you get the fundamentals right.

This guide covers everything you need

SRA regulations, business structures, tax planning, insurance requirements, and marketing strategies for UK solicitors starting a consultancy. Information is current for the 2024/25 tax year.

Below, we break down each critical area to help you build a solid foundation for your legal consultancy business.

1

Understanding SRA Regulations and Public Practice Rules

Before you start, you must understand the SRA's public practice rules. These regulations determine whether you can offer legal services and how you must structure your business. Authorisation, conduct rules, professional indemnity insurance, and client money handling are all mandatory requirements.

If you're leaving a law firm or closing a solicitor's practice, you need to notify the SRA and ensure you're properly authorised to provide legal services. The SRA's handbook sets out strict requirements around:

Authorisation

You must be SRA-authorised to practise as a solicitor

Conduct Rules

All activities must comply with the SRA Code of Conduct

PII Insurance

Mandatory for any legal work you undertake

Accounts Rules

Client money must be handled separately

Important: The SRA's "reserved legal activities" are particularly important. These include litigation, conveyancing, probate, and notarial activities—if you intend to offer these services, you'll need additional permissions and insurance.

Expert Insight

Many solicitors assume they can simply "go freelance" and advise clients. However, if you're advising on matters that constitute reserved legal activities, you still need appropriate SRA authorisation. The "consultancy" label doesn't exempt you from compliance requirements.

2

Choosing Your Business Structure

Your business structure affects your tax liability, administrative burden, and personal liability. In the UK, solicitors typically choose between sole trader, limited company, or LLP structures. For most new legal consultancies, a limited company (Ltd) offers the best balance of tax efficiency and professional protection.

Structure Pros Cons Best For
Sole Trader Simple, full control, minimal admin Unlimited liability Low-risk, part-time consultancies
Limited Company Tax-efficient, limited liability More admin, Companies House filings Full-time, higher-earning consultancies
LLP Partnership-friendly, tax-efficient Requires multiple members Firms with partners

Corporation Tax rates for 2024/25: Main rate is 25% for profits over £250,000. Small profits rate of 19% applies for profits under £50,000. This can be more efficient than income tax rates of 40-45% on higher earnings from a sole trader structure.

Pro-Tip

If your consultancy turnover exceeds £85,000, you must register for VAT with HMRC. Many legal services are exempt from VAT, but advisory and training services are standard-rated. Get this right from day one to avoid penalties.

3

Tax Planning and HMRC Compliance

Your tax obligations as a legal consultant depend on your business structure, but Self Assessment is universal. HMRC requires registration if you're self-employed, even operating through a limited company. Key areas include Income Tax, National Insurance, Corporation Tax, and allowable expenses.

Key Tax Considerations

Income Tax

Personal tax rates of 20%, 40%, and 45% apply to your drawings or salary

National Insurance

Class 2 and Class 4 contributions apply to self-employed profits

Corporation Tax

25% (main rate) or 19% for profits under £50,000

Dividends

No NICs apply, but income tax on dividend income above allowances

Allowable Expenses

Professional subscriptions, office costs, and travel

Record-Keeping Requirements

HMRC requires you to keep records for at least 5 years after the tax return deadline. Cloud accounting software like FreeAgent or Xero integrates with Making Tax Digital (MTD) requirements and makes compliance straightforward.

Employment Contract Warning

If you're providing services to former clients from your previous firm, check your employment contract for any restrictions on business activities or solicitation clauses.

4

Professional Indemnity Insurance and Protection

Professional indemnity insurance (PII) is not optional in legal consultancy—it protects you and your clients. The SRA requires all solicitors providing legal services to have appropriate PII coverage. Minimum coverage is typically £3m for most work, with additional considerations for retroactive and run-off cover.

When Arranging Insurance, Consider:

Minimum Coverage

The SRA sets minimum indemnity limits—typically £3m for most work

Retroactive Cover

Protects against claims for work done before your policy start date

Run-off Cover

Essential if you close your consultancy, covering past work

Cyber Liability

Increasingly important for consultants handling client data digitally

Other Essential Insurances

Public Liability Employers' Liability Buildings & Contents Key Person Insurance

Expert Insight

Don't confuse your PII with your professional body membership. The Law Society and SRA have different requirements, and you may need additional coverage depending on your client base. Check with a specialist legal insurance broker.

5

Lead Generation, Marketing, and Business Development

Without clients, your consultancy won't survive—no matter how excellent your legal expertise. Effective marketing requires digital presence, networking, and professional credibility. LinkedIn is the primary platform for B2B legal services, while SRA advertising rules must be followed.

Digital Marketing Essentials

Professional Website

SEO-optimised site targeting keywords like "legal consultancy," "solicitor consultant," and your specialist areas

Google Business Profile

Essential for local search visibility and attracting nearby clients

LinkedIn Presence

Primary platform for B2B legal services networking and thought leadership

Content Marketing

Blog posts, guides, and webinars demonstrating expertise and building trust

Networking Power

Building relationships with former colleagues, barristers, and other professionals can generate valuable referrals. Many successful consultancies grow entirely through word-of-mouth recommendations.

SRA Advertising Compliance

Advertising legal services in the UK is governed by the SRA Code of Conduct. You must not make misleading statements, put undue pressure on potential clients, or cold-call individuals about legal services.

6

Financial Management and Pricing Strategy

Setting sustainable fees requires balancing market rates, your expertise, and business viability. Legal consultancy rates in the UK vary by specialism and location, with typical hourly rates ranging from £150-£500+. Cash flow management is critical—setting aside 25-30% of income for tax is essential.

Common Pricing Models

Hourly Rates

Per hour depending on experience and specialism

Fixed Fees

Project-Based

Popular for defined projects like contract reviews

Retainers

Cash Flow Management Tip

Unlike employed solicitors, you'll need to manage your own tax payments, National Insurance contributions, and VAT obligations. Setting aside 25-30% of income for tax is a sensible starting point to avoid cash flow surprises.
