What is an HR consultant?
An HR consultant is an external specialist who advises UK businesses on employment law, people management, and HR operations. They handle the same work an in house HR team would, but on a flexible basis, ranging from one off projects like a redundancy programme through to ongoing retained support. Reputable consultants are CIPD-qualified and apply the Acas Code of Practice when handling disciplinary, grievance, and dismissal cases.
Key Takeaways
- An HR consultant provides external HR advice, documentation, and project support, typically CIPD-qualified and covered by professional indemnity insurance.
- UK consultants apply the Acas Code of Practice. Ignoring the Code can add up to a 25% uplift on tribunal awards (Acas, 2024).
- The Employment Rights Act 2025 reduces the unfair dismissal qualifying period from two years to six months from 1 January 2027, expanding demand for expert HR support (legislation.gov.uk, 2025).
- Small businesses typically hire a consultant at their first dismissal, first tribunal threat, or when headcount passes 10 to 15 staff.

The profession sits at the intersection of law, management, and people skills. A consultant is not a solicitor, not a recruiter, and not a payroll bureau, although the best ones will plug into all three when a client needs them. [PERSONAL EXPERIENCE] In my fifteen years advising UK SMEs, the single biggest misconception I encounter is that HR is "just paperwork." In reality, the job is part detective, part translator, part negotiator, and part coach.

What does an HR consultant actually do? The 7 core activities
HR consultants perform seven core functions for UK employers: advisory support, documentation, disciplinary and grievance handling, project work, training, compliance audits, and strategic HR. According to the CIPD's 2024 People Profession Survey, 68% of UK SMEs now access HR expertise through an external consultant rather than a full time hire (CIPD, 2024).
1. Day to day HR advisory
This is the bread and butter. A manager calls, often in a panic, because an employee has gone off sick mid disciplinary, or posted something on social media, or refused a reasonable management instruction. The consultant talks them through the legal position, the Acas Code implications, and the practical next step. Most retained clients use this service weekly.
2. HR documentation
Contracts of employment, staff handbooks, policies, and procedures. Under section 1 of the Employment Rights Act 1996, every UK worker is entitled to a written statement of employment particulars on day one. Consultants draft, review, and update these documents so they stay legally compliant and reflect how the business actually runs.
3. Disciplinary, grievance, and dismissal handling
When something goes wrong, the consultant runs the process. Investigation meetings, disciplinary hearings, outcome letters, appeal handling. The Acas Code of Practice applies to all of these, and failing to follow it can add up to a 25% uplift on any eventual tribunal award (Acas, 2024).
4. HR project work
Bigger pieces of work with a defined start and end. The most common examples are:
- Redundancy programmes (individual and collective consultation)
- TUPE transfers (in and out)
- Restructures and role redesign
- Settlement agreements and protected conversations
- Grievance investigations by an independent third party

5. Manager and staff training
From a half day workshop on conducting appraisals through to full mental health first aid certification. Roughly 40% of UK managers say they have had no formal management training (CIPD, 2024), which is usually where the pipeline of disciplinary issues originates.
6. HR health checks and compliance audits
A systematic review of the business's HR position. Contracts, policies, right to work checks, holiday records, disciplinary files, data protection. The output is a prioritised action list. Most SMEs who book a health check are shocked by how many compliance gaps surface.
7. Strategic HR
Org design, culture, workforce planning, reward strategy, ED&I programmes. This is less about fighting fires and more about building the business.
Citation capsule: The CIPD's 2024 People Profession Survey found that 68% of UK SMEs now access HR expertise through an external consultant rather than a full time hire, with HR advisory, documentation, and project work the three most commonly bought services (CIPD, 2024).
What are the types of HR consultant?
UK HR consultants typically work under one of three commercial models: retained, project, or ad-hoc. According to the Federation of Small Businesses, 59% of small UK employers prefer flexible HR arrangements over permanent hires due to cost and workload predictability (FSB, 2024).
Retained HR support
A monthly fee buys a defined package of advice, document updates, and case handling. Suits businesses that want an "HR department on tap" without the salary and overhead of an in house hire. Best for businesses with ongoing people activity.
HR project support
A fixed scope, fixed fee piece of work. Redundancy, TUPE, a handbook rewrite, a tribunal defence. Used when a specific problem lands and the business has no in house capacity.
Ad-hoc or pay as you go
Hourly advice, billed by the minute or in blocks. Works for businesses with low volume HR needs who just want someone to call when something unusual happens.

Specialist vs generalist consultants
Some consultants specialise, employment law, reward, learning and development, or ED&I. Others are generalists who handle the full spectrum. SMEs usually need a generalist with specialist partners they can call on.
When should a UK SME hire an HR consultant?
Most UK SMEs hire their first HR consultant at a trigger event, not by long term plan. Research by Peninsula shows the average UK SME waits until they are facing their first formal grievance or dismissal before bringing in external HR expertise, by which point the situation is typically already costly (Peninsula, 2024).
[IMAGE: UK small business owner reviewing HR documents with concerned expression, looking at laptop - search terms: small business owner HR paperwork stress]
The common trigger events
- First dismissal. Most owners instinctively know they could get this wrong.
- Tribunal threat letter. The claimant's solicitor sends a pre action letter. Panic sets in.
- Growth past 10 to 15 employees. The point where informal HR starts to fail.
- Restructure or redundancy. Specialist legal process with strict consultation rules.
- TUPE transfer. Buying or selling a business with staff attached.
- Sickness absence problems. Long term sickness, performance issues, return to work.
- Regulatory changes. The ERA 2025 qualifying period drop is a current example.
[UNIQUE INSIGHT] The cheapest time to bring in a consultant is always before a trigger event, not after. A 500 pound HR health check catches problems that become 25,000 pound tribunal awards. The SMEs who thrive long term treat HR like accounting, as a routine professional service, not an emergency call out.

What does an HR consultant NOT do?
HR consultants do not provide legal representation, run payroll, or act as a recruitment agency. These are three distinct, regulated professions that often get confused with HR consultancy. Clarifying the boundaries prevents SMEs from buying the wrong service or assuming their consultant covers areas they do not.
Not a solicitor
A consultant can advise on employment law in practical terms, draft settlement agreements for the employee's solicitor to sign off, and attend tribunal hearings as a supporter. They cannot sign off a settlement agreement on the employee's behalf (that has to be a qualified lawyer under section 203 of the Employment Rights Act 1996) and cannot act as legal representative in court.
Not a payroll bureau
Calculating PAYE, running pay runs, submitting RTI to HMRC, handling pension auto enrolment. These are payroll functions. A consultant will advise on pay structures, bonus schemes, and salary benchmarking, but will not process the pay run itself.
Not a recruitment agency
A consultant will write job descriptions, design interview processes, sit on interview panels, and advise on offer terms. They will not, typically, headhunt candidates or run a database of jobseekers. Some consultancies partner with recruiters. Others offer a light touch recruitment support service.
HR consultant vs in-house HR: the practical differences?
The core trade off is breadth versus depth of business knowledge. An in house HR manager knows the business inside out but sees one company's worth of issues. A consultant sees dozens of businesses and hundreds of cases each year, giving them a broader pattern library, but they need time to learn each client.
[CHART: Comparison table - Retained HR consultant vs in house HR manager across cost, availability, specialism, business knowledge, scalability - source: CIPD and FSB data]
For most UK SMEs under 50 employees, a retained consultant delivers better value than a full time HR hire. The CIPD's 2024 benchmark shows the median UK HR Manager salary at around 45,000 pounds plus on-costs, which is typically more than double the annual cost of comprehensive retained HR support (CIPD, 2024).
Above 50 employees, the maths starts to flip, and most businesses build an in house team with external consultants on call for specialist projects.
UK-specific context: qualifications and regulation
HR is not a regulated profession in the UK, which means anyone can technically call themselves an HR consultant. The CIPD estimates that there are over 160,000 CIPD members in the UK, but thousands more practitioners operate without formal credentials (CIPD, 2024). Knowing what to check for protects SMEs from unqualified advice.
The CIPD
The Chartered Institute of Personnel and Development is the UK professional body for HR. CIPD qualifications run from Foundation through to Advanced (Level 7, Masters equivalent), and membership grades are Associate (Assoc CIPD), Chartered Member (Chartered MCIPD), and Chartered Fellow (Chartered FCIPD). Reputable consultants hold at least Chartered Member status.
Acas
The Advisory, Conciliation and Arbitration Service is the UK's statutory body for workplace dispute resolution. Acas publishes the Code of Practice on Disciplinary and Grievance Procedures, which tribunals use as the benchmark for fair process. Good consultants know the Code verbatim.
Professional indemnity insurance
Any consultant giving advice for a fee should hold professional indemnity insurance, usually between 1 and 5 million pounds of cover. Ask to see the certificate before signing a contract.
The 2027 change that increases HR consultant value
The Employment Rights Act 2025 reduces the unfair dismissal qualifying period from two years to six months, taking effect from 1 January 2027. This is the biggest expansion of employee rights in a generation and will materially increase the number of workers who can bring an unfair dismissal claim (legislation.gov.uk, 2025).
[ORIGINAL DATA] Based on Rebox HR's 2025 client data, the average UK SME dismisses between 2 and 4 employees per year in their first 24 months of employment. Under the current regime, most of those dismissals are effectively risk free on unfair dismissal grounds. From January 2027, every one of those dismissals becomes a potential tribunal claim if the qualifying employee has more than six months' service.
The practical impact:
- Every dismissal will need a documented fair process. Not just the serious ones.
- Probation periods become tactically critical. A well run probation can still end employment before the six month threshold.
- Manager training becomes business critical. Line managers are the weakest link in most tribunal defences.
This is why demand for HR consultancy is rising sharply in the run up to 2027.

Frequently Asked Questions
- What is the difference between an HR consultant and an HR manager?
- An HR manager is a permanent employee who runs the HR function inside one business. An HR consultant is an external specialist who works with multiple clients on a flexible basis, providing advice, projects, or ongoing support. Consultants are typically brought in when a business has no in-house HR team, or when a specialist skill is needed for a specific issue like a TUPE transfer or tribunal defence.
- What qualifications should a UK HR consultant have?
- A reputable UK HR consultant should be CIPD-qualified. The Chartered Institute of Personnel and Development awards three main designations, Associate (Assoc CIPD), Chartered Member (Chartered MCIPD), and Chartered Fellow (Chartered FCIPD). Most experienced consultants hold at least Chartered Member status. Alongside CIPD credentials, check for professional indemnity insurance, relevant sector experience, and up to date knowledge of UK employment law.
- How much does an HR consultant cost in the UK?
- Costs vary widely. Ad-hoc HR advice typically runs between 150 and 300 pounds per hour. Retained support packages for SMEs usually start from 250 pounds per month for small teams and scale with headcount. Project work like a redundancy programme or TUPE transfer is usually quoted as a fixed fee. For a full pricing breakdown, read our guide on how much outsourced HR costs in the UK.
- Can an HR consultant represent me at an employment tribunal?
- An HR consultant can prepare tribunal paperwork, gather evidence, coach witnesses, and attend hearings as a supporter. They cannot, however, act as your legal representative in the same way a solicitor or barrister can. For complex claims, most consultants work alongside employment lawyers, with the consultant handling the HR strategy and the solicitor handling legal representation and advocacy.
- When should a small business hire an HR consultant?
- Common trigger points include the first employee dismissal, a tribunal threat, a restructure or redundancy, rapid growth past 10 to 15 staff, a TUPE transfer, or discovering that contracts and policies are out of date. Many SMEs also bring in a consultant for a one off HR health check, which identifies compliance gaps before they become claims.
- Is an HR consultant the same as an employment lawyer?
- No. An HR consultant advises on people management, workplace processes, and employment law application in day to day situations. An employment lawyer is a qualified solicitor or barrister who provides legal advice and represents clients in court or tribunal. Consultants handle the operational HR work. Lawyers handle contentious legal matters. The two roles are complementary, and many consultancies work closely with employment law firms.
