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.

Worth thinking about…
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.
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.
Realistic income figures based on typical HR consultancy journeys. The mix of retainer and project work is the key variable.
Starting Out
Building client base, first retainers, establishing reputation
Established Consultant
Full retainer base, project work, referrals from solicitors and accountants
Senior Specialist / Small Practice
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.
HR consultancy has very low startup costs. The main ongoing investment is employment law reference services and CPD to stay current.
Solo HR Consultant (Home-Based)
£500 – £2,500
One person, working from home, serving SME clients.
HR Consultancy (Small Practice)
£3,000 – £8,000
Director plus associates, serving larger SMEs and mid-market clients.
Don't forget ongoing costs
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.
These are the fundamentals that determine whether your HR consultancy builds a sustainable practice or struggles to win and retain clients.

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.
