How To Start A HR Consultancy

A practical guide for experienced HR professionals thinking about starting their own HR consultancy.

HR consultancy is one of the most in-demand professional services for small and medium-sized businesses. Most SMEs cannot afford a full-time HR director but face the same employment law obligations, people challenges and cultural issues as larger organisations. An experienced HR consultant fills this gap — providing expert, practical support on a flexible basis. The market is large, the barriers to entry are manageable and the demand for good HR advice is consistent.

Is This Business Right For You?

Before you invest time and money, it helps to be honest about whether this business suits your skills, lifestyle and goals.

This could suit you if…

  • You have 5+ years of HR experience and a CIPD qualification (Level 5 or 7)
  • You have up-to-date knowledge of UK employment law and HR best practice
  • You are comfortable advising business owners directly — not just supporting internal HR teams
  • You can work independently and manage multiple client relationships simultaneously
  • You want to leverage your HR expertise across multiple businesses rather than one employer

Worth thinking about…

  • Employment law changes regularly — you must commit to ongoing CPD to stay current
  • SME clients often need urgent advice on sensitive issues — you need to be available and responsive
  • Building a consistent client base takes time — most HR consultants take 12–18 months to reach full capacity
  • Professional indemnity insurance is non-negotiable — employment law advice carries real liability risk
  • Some HR work is emotionally demanding — disciplinaries, redundancies and grievances require resilience

Why People Choose This Business

HR consultancy attracts experienced HR professionals who want to work on their own terms, serve multiple clients and earn significantly more than most employed HR roles allow. Here is what draws people to it.

Large, underserved SME market

There are over 5 million SMEs in the UK. Most have fewer than 50 employees and no in-house HR function — but they face the same employment law obligations as large organisations. This is your primary market.

Retainer income model

HR consultants typically work on monthly retainers — clients pay a fixed monthly fee for a defined level of support. Retainers provide predictable, recurring income that makes cash flow far more manageable than project-based work.

High earning potential

Experienced HR consultants charge £400–£1,000+ per day. A consultant with 10 retainer clients at £500/month generates £60,000/year in retainer income alone — before any project work.

Low startup costs

An HR consultancy requires minimal upfront investment — professional indemnity insurance, a laptop, a good employment law reference service and a professional LinkedIn profile. Most consultants start for under £2,000.

Variety of work

HR consultancy spans recruitment, onboarding, performance management, disciplinaries, redundancies, culture, wellbeing and strategic people planning. No two clients are the same — the work is genuinely varied.

Genuine impact on businesses

Good HR advice protects businesses from costly employment tribunal claims, helps them attract and retain talent and builds cultures where people perform at their best. The impact of your work is tangible and significant.

The Opportunity

Why this can be a viable and rewarding business to build.

Market Overview

The UK SME market is the primary opportunity for independent HR consultants. Businesses with 10–250 employees typically lack in-house HR expertise but face complex employment law obligations, regular people challenges and growing expectations from employees. HR consultants who serve this market with practical, accessible advice — rather than overly legalistic or corporate approaches — build loyal, long-term client relationships.

Day Rate Range

Generalist HR: £350–£600/day. Specialist (employment law, TUPE, reward): £600–£1,200/day.

Retainer Income

SME retainers: £300–£1,500/month. 10 retainer clients at £600/month = £72,000/year recurring income.

Revenue Potential

A solo HR consultant with 10 retainers + project work generates £80,000–£150,000+ per year.

Employment Tribunal Risk

The average employment tribunal award is £10,000–£15,000. Good HR advice prevents claims — clients understand this value.

What Could You Earn?

Realistic income figures based on typical HR consultancy journeys. The mix of retainer and project work is the key variable.

Starting Out

  • Retainer clients: 2–5 retainer clients
  • Weekly: £500–£1,500 per week
  • Annual: Around £25,000–£70,000 per year

Building client base, first retainers, establishing reputation

Established Consultant

  • Retainer clients: 8–15 retainer clients
  • Weekly: £1,500–£3,500 per week
  • Annual: Around £75,000–£150,000 per year

Full retainer base, project work, referrals from solicitors and accountants

Senior Specialist / Small Practice

  • Clients: 15+ clients or associate team
  • Weekly: £3,000–£7,000+ per week
  • Annual: £150,000–£350,000+ per year

Specialist positioning, associate network, larger project engagements

Figures are illustrative. HR consultancy income depends on your day rate, number of retainer clients and the volume of project work. Retainer income is more predictable than project income — aim to build a retainer base that covers your fixed costs before relying on project work.

What Could It Cost To Start?

HR consultancy has very low startup costs. The main ongoing investment is employment law reference services and CPD to stay current.

An employment law reference service (such as XpertHR, Croner or Practical Law) is essential — employment law changes regularly and you cannot rely on memory alone. This is a professional necessity, not an optional extra.

What You Need To Know First

These are the fundamentals that determine whether your HR consultancy builds a sustainable practice or struggles to win and retain clients.

Qualifications and Credibility

  • CIPD Level 5 (Associate) or Level 7 (Chartered) is the recognised professional standard for HR
  • Chartered MCIPD or FCIPD status significantly increases credibility with corporate clients
  • Employment law knowledge must be current — the law changes regularly and clients rely on your accuracy
  • Specialist qualifications (employment law, reward, organisational development) command premium rates
  • Membership of CIPD provides access to resources, CPD and professional credibility
  • Case studies and testimonials from satisfied clients are as important as formal qualifications

Professional Indemnity Insurance

  • PI insurance is non-negotiable for HR consultants — employment law advice carries real liability risk
  • If your advice leads to an employment tribunal claim, PI insurance covers your legal costs and any award
  • Cover levels typically start at £500,000 — many clients require £1,000,000+
  • Arrange cover before you provide any paid HR advice to clients
  • CIPD and specialist HR insurance brokers offer competitive rates for HR consultants
  • Review your policy annually as your turnover and client contract values grow

Employment Law Knowledge

  • Employment law is the foundation of HR consultancy — your advice must be legally accurate
  • Key areas: contracts of employment, disciplinary and grievance procedures, redundancy, TUPE, discrimination
  • Employment law changes regularly — subscribe to an employment law update service
  • For complex cases, refer clients to an employment solicitor rather than advising beyond your competence
  • Build a relationship with a specialist employment law firm for referrals and technical support
  • Document all advice given to clients — it protects you and demonstrates professionalism

Pricing and Service Models

  • Retainer model: monthly fee for a defined level of support — the most common model for SME HR consultants
  • Day rate: straightforward for project work — typically £350–£1,000/day depending on specialism
  • Project fee: fixed price for a defined piece of work (e.g. handbook review, redundancy process)
  • Retainers provide predictable income and build deeper client relationships than ad hoc work
  • Price retainers based on the number of employees, complexity of the business and level of support required
  • Review retainer fees annually — most clients accept modest increases if you deliver consistent value

Client Acquisition

  • Most HR consultants win their first clients through their existing professional network
  • Accountants and solicitors are excellent referral sources — they regularly encounter clients with HR needs
  • LinkedIn is the most effective digital channel for B2B HR consultancy
  • Local business networks (BNI, Chamber of Commerce, FSB) generate SME introductions
  • Offer a free HR audit or employment contract review to reduce the risk of a first engagement
  • Ask every satisfied client for a referral — most will not volunteer one without being asked

Business Structure & Tax

  • Sole trader: simple to set up, but you pay income tax on all profits
  • Limited company: more tax-efficient above ~£50,000 profit; salary + dividends structure
  • IR35 may apply if you work through a limited company for a single client who controls your work
  • Keep records of all income, expenses and mileage from day one
  • Use an accountant who understands consultancy and contractor tax structures
  • Register for VAT when turnover exceeds £90,000 — or voluntarily if your clients are VAT-registered

Is The Market Competitive?

Understanding the competitive landscape helps you position your business more effectively from the start.

Competition Level

Medium

The HR consultancy market is competitive but fragmented. Large HR firms serve enterprise clients; independent consultants dominate the SME market. SME owners prefer working with an individual consultant who knows their business rather than a faceless firm. HR consultants who build strong referral networks through accountants, solicitors and business networks consistently win more work than those who rely on cold outreach.

What this means for you

  • SME clients prefer individual consultants over large firms — personal relationships matter
  • Referrals from accountants, solicitors and business networks are the most efficient source of new clients
  • Specialist positioning (e.g. "HR for care homes", "HR for professional services firms") commands premium rates
  • Retainer clients are stickier than project clients — prioritise building a retainer base
  • Employment law expertise is a genuine differentiator — invest in staying current
  • Thought leadership (LinkedIn content, speaking, writing) builds credibility that attracts inbound enquiries

What Could Make You Stand Out?

The HR consultants who build thriving practices are those who are known for practical, accessible advice and who generate referrals consistently.

Specialise in a Sector or Service

  • Sector specialists (care, hospitality, professional services, retail) command premium rates
  • Service specialists (TUPE, reward, organisational design) win larger project engagements
  • A clear specialism makes marketing easier and referrals more targeted
  • You can always broaden your scope later — build credibility in one area first

Build a Referral Network

  • Accountants and solicitors regularly encounter clients with HR needs — build relationships with them
  • Employment solicitors refer HR work they cannot handle themselves — and vice versa
  • Business networks (BNI, Chamber of Commerce) generate consistent SME introductions
  • Reciprocal referral relationships with complementary consultants multiply your reach

Publish Practical HR Content

  • LinkedIn articles on employment law updates and HR best practice demonstrate expertise
  • A regular newsletter to clients and prospects keeps you top of mind
  • Practical guides (e.g. "How to handle a disciplinary") attract inbound enquiries from SME owners
  • Speaking at business events and webinars builds credibility and generates introductions

Create a Suite of HR Templates

  • A library of employment contracts, policies and procedures is a valuable asset for clients
  • Templates save clients time and reduce their legal risk — they are a tangible deliverable
  • Branded HR templates reinforce your professionalism and make your service more tangible
  • Templates can be sold as a standalone product or included in retainer packages

Your Step-By-Step Journey

Follow these steps in order. Qualifications, insurance and your first retainer clients are the foundations of a sustainable HR practice.

1

Ensure Your Qualifications and Knowledge Are Current

HR qualifications guide

Before you advise clients, make sure your HR knowledge and employment law understanding are up to date.

  • Review your CIPD qualification level — Level 5 or 7 is the expected standard

  • Subscribe to an employment law update service (XpertHR, Croner, Practical Law)
  • Identify any gaps in your knowledge and address them through CPD
  • Renew or upgrade your CIPD membership
2

Define Your Services and Target Market

Service design guide

Be specific about what you offer and who you serve. Generalist HR consultants compete on price; specialists compete on expertise.

  • Define your core services: employment law advice, policies and procedures, disciplinaries, redundancy, TUPE, etc.
  • Identify your target client: industry, size, typical HR challenges
  • Decide on your pricing model: retainer, day rate or project fees
  • Research what competitors charge in your area and niche
  • Write a clear one-page overview of your services and the value you deliver
3

Sort the Business Foundations

Business setup guide

Register your business, arrange insurance and set up the systems you need to operate professionally.

  • Register as a sole trader or incorporate a limited company
  • Arrange professional indemnity insurance — minimum £500,000 cover
  • Open a business bank account
  • Set up accounting software and a simple invoicing system
  • Prepare standard client agreements and terms of business
4

Build Your Credibility Assets

Credibility building guide

Before you market actively, build the assets that demonstrate your expertise and track record.

  • Update your LinkedIn profile with a clear, specific headline and summary
  • Create a professional website with your services, your background and client testimonials
  • Develop a suite of HR templates (employment contracts, policies, procedures) to offer clients
  • Gather testimonials from former colleagues, managers or early clients
  • Write 2–3 LinkedIn articles on employment law topics relevant to your target clients
5

Win Your First Retainer Clients

Client acquisition guide

Activate your network, build referral relationships and convert your first clients to retainers.

  • Contact every SME owner and HR professional in your network
  • Build relationships with local accountants and solicitors — they are your best referral sources
  • Offer a free HR audit or employment contract review to reduce the risk of a first engagement
  • Join local business networks (BNI, Chamber of Commerce, FSB)
  • Ask every satisfied client for a referral and for introductions to other business owners
6

Build a Sustainable Practice

Practice growth guide

Once you have a base of retainer clients, focus on deepening relationships, adding associates and building your reputation.

  • Aim for 8–12 retainer clients as your core income base
  • Add project work and specialist engagements on top of retainer income
  • Build an associate network to handle overflow and specialist work
  • Publish HR content consistently — LinkedIn, newsletter, speaking
  • Review your pricing annually — most clients accept modest increases if you deliver consistent value
