Do I Need an HR Consultant? Signs Your Small Business Has Outgrown DIY HR

Most small businesses don't need a full-time HR person.

But there comes a point where doing HR yourself starts costing more than it saves. Usually in time, stress and the odd problem that could have been avoided.

An HR consultant can help you get the basics right, deal with tricky situations and put things in place so you're not starting from scratch every time. You bring them in when you need them, rather than paying for someone full time.

So how do you know when you've reached that point?

These are the signs I look for.

1. You're making it up as you go along

This is really common, and I don't say it as a criticism.

When a business is small, HR is often whoever has a spare minute. The owner. The office manager. Someone in finance.

People do their best. They Google things. They ask a friend who runs another business.

They copy a template.

That works for a while. But at some point, you end up with contracts that don't match, policies nobody has read, and decisions that aren't consistent from one person to the next.

If you've ever thought "how did we handle this last time?" and nobody knows, that's a sign.

2. You've got a people problem that's keeping you up at night

A difficult employee. A grievance. Someone off sick for weeks with no clear plan. A performance issue that's been going on for months.

These are the situations where getting it wrong can be costly. And they're also the ones that take up a huge amount of headspace.

Having someone to talk it through with, who has dealt with it many times before, makes a big difference. Not only in getting the process right, but in feeling less alone with it.

3. You're growing quickly

Growth is great. It also changes things.

At ten people, you probably know everyone well and can sort most things out with a conversation. At 30 or 50, that stops working.

You'll need clearer roles, a proper onboarding process, consistent pay decisions and managers who know how to manage. Most growing businesses don't have that in place until something forces the issue.

4. Your managers have never been trained to manage

Lots of managers are promoted because they're great at their job. Not because they're great at managing people.

Then they're expected to handle absence, performance, difficult conversations and team conflict with no support.

If your managers keep coming to you with every people issue, or avoiding them altogether, they probably need more help.

5. Your paperwork hasn't been looked at in years

When did you last review your contracts and staff handbook?

Employment law changes. The Employment Rights Act 2025 is bringing in a lot of changes between 2026 and 2027, including unfair dismissal rights after six months' service from January 2027.

If your documents still say what they said five years ago, they're almost certainly out of date.

6. You've got a big change coming

A restructure. A redundancy. A TUPE transfer. A new HR system. Changing shift patterns or contracts.

These are the moments where a clear process really matters. Consultation rules, timelines, letters and conversations all need to be right.

This kind of work often doesn't justify a permanent hire, but it does need someone who knows what they're doing for a few weeks or months.

7. HR is taking up far too much of your time

If you're spending hours on HR admin, chasing forms, writing letters and answering the same questions, that's time you're not spending on running the business.

Sometimes the answer isn't more help. It's better processes. Simple templates, clearer guidance and a bit of automation can save hours every month.

8. You're worried about getting it wrong

This one is simple. If you're regularly unsure whether you're doing the right thing, it's worth getting advice.

Most HR problems don't start with a disaster. They start with a small decision that nobody thought much about at the time.

What does an HR consultant actually do?

It depends on what you need. But typically, an HR consultant will:

• Give practical advice on employee issues as they come up.

• Write or update contracts, policies and your staff handbook.

• Support managers with difficult conversations, absence and performance.

• Help with change, like restructures, redundancies or new systems.

• Provide extra HR capacity when you're stretched.

• Help you put simple processes in place so things run more smoothly.

A good consultant should make you more confident, not more dependent on them.

What should you look for in an HR consultant?

A few things I'd suggest checking:

• Are they CIPD qualified? It's the professional body for HR in the UK.

• Have they worked in a business like yours? Real operational experience matters. I've spent more than 15 years in senior HR roles, most recently leading HR for around 1,300 employees, across sectors like contract catering, hospitality, education and travel.

• Are they insured? Professional indemnity insurance is important.

• Do they speak plainly? You should come away from a conversation knowing what to do next, not more confused.

• Are they clear about what they don't do? An HR consultant isn't a solicitor. A good one will tell you when you need legal advice.

What if someone already does HR alongside their job?

That's really common, and it doesn't mean you need to replace them.

Often the best setup is a mix. Someone in-house who knows the business and handles the day-to-day, with an HR consultant they can call on for the trickier stuff.

It gives them backup. A second opinion before a difficult meeting. Help with a policy they've never written before. Someone to check a process is fair before it goes any further.

It can also help them grow. Lots of people who've ended up "doing HR" are really good at it. They've never had anyone to learn from.

So if you've got an office manager or operations lead picking up HR, an HR consultant can make their life easier rather than taking their job.

Where I've landed

I don't think every small business needs an HR consultant all the time.

But I do think most small businesses reach a point where some expert help would save them time, money and a lot of worry.

The trick is not waiting until something has gone wrong.

Frequently asked questions

What is the difference between an HR consultant and an HR manager?

An HR manager is usually a permanent employee. An HR consultant works with you when you need them, on specific issues or projects, so you're not paying for a full-time role.

Can an HR consultant help with a single issue?

Yes. Many small businesses bring in an HR consultant for one issue, like a grievance, a restructure or updating contracts, and then come back when something else comes up.

Can an HR consultant give legal advice?

No. An HR consultant can give practical HR advice and help you follow a fair process, but they aren't a solicitor. For legal advice, you should speak to an employment lawyer.
