How to Start an HR Consultancy in the UK

HR consultancy is a natural step for experienced HR professionals who want to work independently. Small businesses need HR support but cannot justify a full-time hire — and that is where you come in. This guide covers everything you need to get your HR consultancy started.

Qualifications and Memberships

No mandatory qualifications are required, but clients expect to see professional credentials:

• CIPD membership (Chartered Institute of Personnel and Development) — the gold standard for HR professionals. Associate (Level 5), Chartered Member (Level 7), or Chartered Fellow.
• CIPD qualifications — if you do not already hold one, a Level 5 or 7 qualification demonstrates competence
• Employment law training — essential to keep your advice current

CIPD membership costs £150–£250 per year depending on your level and is a deductible business expense.

Sole Trader or Limited Company?

Most HR consultants start as sole traders. It is simple and low-cost. A limited company becomes worth considering at higher profit levels or if clients prefer to contract with a limited company. If you take on long-term placements through agencies, consider IR35 implications.

Registering with HMRC

Register for Self Assessment within three months. VAT at £90,000 turnover. If your clients are VAT-registered businesses, voluntary registration below the threshold can be worthwhile.

Insurance

• Professional indemnity insurance — essential. Your advice directly affects how businesses manage their people and comply with employment law. Cover starts at around £200–£500 per year.
• Public liability — if you visit client premises
• Cyber insurance — you handle sensitive employee data
• Employers' liability — if you hire staff

Claimable Expenses

• CIPD membership and subscriptions
• Legal reference materials — employment law updates, HR publications
• Software — HR management systems, document templates, CRM, project management tools
• Home office costs — flat rate or actual proportion
• Travel — to client sites, at 45p per mile or actual costs
• Training and CPD — conferences, webinars, courses
• Marketing — website, LinkedIn advertising, networking events
• Phone and broadband
• Professional indemnity insurance
• Accountancy fees
• Co-working space — if you use one

Accounted tracks your expenses and categorises them automatically.

Setting Your Rates

• Day rate — £400–£800 for experienced HR consultants
• Hourly rate — £50–£120
• Retainer — £500–£2,000 per month for ongoing support
• Project-based — redundancy programmes, policy reviews, TUPE projects — priced per project

Retainer arrangements provide predictable income and are worth pursuing once you have established relationships.

Industry-Specific Tax Considerations

IR35

If you work primarily for one client, on their premises, under their direction, IR35 may apply. Maintain multiple clients, use your own equipment, and ensure you have genuine autonomy over how you deliver your work.

Data Protection

If you process employee data on behalf of clients, you are likely a data processor under GDPR. Register with the ICO (£40 per year) and ensure you have proper data processing agreements with your clients.

Professional Development

All training and CPD that maintains or updates your existing HR skills is tax-deductible. Courses that teach entirely new skills (e.g., qualifying as a solicitor) are not.

Building Your Client Base

• Your network — former employers and colleagues are your best source of initial work
• LinkedIn — essential for B2B professional services
• CIPD events — networking with other HR professionals and potential clients
• Local business networks — FSB, Chamber of Commerce, BNI
• Referral partnerships — accountants, solicitors, and business consultants
• Content marketing — write about employment law changes and HR best practice

Bookkeeping Tips

• Separate business and personal finances
• Track retainer income vs project income — understand your revenue mix
• Invoice promptly — corporate clients often have 30-day payment terms
• Set aside 25–30% of profits for tax
• Monitor your pipeline — project-based work can be lumpy
