The short version: good HR advice for a growing small business is specific to your headcount, your sector, and your risk right now, not a generic policy pack sold to everyone from a 5-person agency to a 500-person warehouse. Before you pay anyone, ask them how many businesses your exact size they’ve advised in the last year, and if the answer is vague, walk away. The right advisor saves you money by telling you what you don’t need yet, not just by selling you everything they’ve got.
Why generic HR advice breaks the moment you hire employee number six
When you’re a team of two or three, HR is mostly common sense and a decent contract template. The moment you cross five or six people, things change fast: you need a proper disciplinary process, a real probation policy, clarity on holiday accrual, and someone who understands that a bad hire at this size can sink you. I’ve watched founders try to run this stage on the same free contract template they used for their first employee, and it works right up until it doesn’t.
The trouble is that most HR advice sold to small businesses is written for a hypothetical 50-person company. It covers redundancy consultation periods and grievance escalation panels you’ll never need at headcount 8. Meanwhile it skips the thing that trips people up at that stage, which is how to handle an underperforming employee in the first three months without it turning into a legal headache. Advice that isn’t sized to your business isn’t wrong exactly, it’s just expensive noise.
The questions that separate real HR advice from expensive guessing
Before you sign anything or pay a retainer, ask whoever you’re considering these six questions. Their answers tell you more than any brochure.
- How many businesses your exact size (not bigger, not smaller) have you advised in the last 12 months?
- What’s the first thing you’d tell me to fix, and why that one first?
- Do you charge for template documents separately, or are they included?
- What happens if I have an actual dispute, do you handle it or hand me off to a solicitor?
- Can you show me one example of advice you gave that turned out to be wrong, and what you changed?
- What’s your view on flexible or remote working policies for a team under 15 people?
That last question matters more than people think. If you’re building a distributed team, the advice you need looks nothing like the advice for an office-based one, and a lot of HR consultants only really know one model. If your growth plan includes hiring remotely, the same logic that applies when you’re scanning remote jobs for project managers right now to understand what candidates expect applies in reverse when you’re the employer: your HR policies need to match how people want to work, not how your advisor’s other clients work.
My £1,400 lesson in what “good” HR advice costs you
A few years ago, while I was still running a bigger team, I paid a well-regarded HR consultancy £1,400 for a full policy pack: contracts, staff handbook, disciplinary procedure, the works. It looked impressive. It was also almost entirely generic, lifted from a template built for a call centre with shift patterns and a union rep, none of which applied to my small, mostly remote marketing team. When an actual performance issue came up eighteen months later, the disciplinary procedure I’d paid for referenced steps and timelines that made no sense for a five-person business, and I had to pay a solicitor separately to tell me what to do.
The lesson wasn’t that the consultancy was incompetent. It’s that they sold me a document, not judgement. Good HR advice is judgement applied to your specific situation. A document is a starting point at best. If I’d asked the six questions above before handing over that £1,400, I’d have found out within five minutes that they’d never advised a business under 30 people that year. That single fact would have saved me the money and the headache.
What good HR advice looks like at each stage of growth
1 to 5 employees
At this size, you mostly need solid contracts, a clear probation period (three months is standard in the UK, though some businesses use six), and someone on call for the one-off awkward question. You don’t need a full handbook yet. A fractional HR advisor charging by the hour, somewhere around £60 to £120 an hour depending on your region, is usually enough. Anyone trying to sell you a full retainer at this stage is selling you more than you need.
6 to 20 employees
This is where a proper handbook earns its keep, along with written policies on sickness absence, flexible working requests, and disciplinary and grievance procedures. This is also the stage where I’d recommend a monthly retainer with an HR advisor, somewhere between £200 and £600 a month depending on how hands-on you need them, because you’ll hit two or three real situations a year that need judgement, not a template.
20 to 50 employees
Now you likely need someone with employment law depth, not just generalist HR knowledge, because your exposure to tribunal claims goes up with headcount. This is a good point to have a named employment law solicitor on retainer alongside your HR advisor, and to make sure someone internally owns HR day to day even if it’s not their full-time job.
At every one of these stages, the advice should come with a plain answer to “what happens if this goes wrong.” According to the UK government’s own guidance on employment disputes, contesting a tribunal claim costs UK employers thousands of pounds in legal fees even when they win, and that’s before you count the management time and stress. You can read the government’s overview of the employment tribunal process yourself, and it’s worth doing once so you know what you’re trying to avoid.
The uncomfortable bit nobody selling you HR advice wants to say out loud
Here’s the part most advice on this topic skips. A lot of HR advice, especially from people with a corporate background, is built to protect the business from imaginary lawsuits rather than to help it grow. That’s not malicious, it’s just how they were trained. Someone who spent fifteen years doing HR at a company with 3,000 staff and a full legal department has a completely different risk tolerance to what a 12-person business needs. They’ll tell you to document everything in triplicate, run every decision past a lawyer, and treat every new hire like a potential future claimant. That instinct made sense in their old job. In yours, it slows down every hiring decision and makes your managers scared to have honest conversations with underperforming staff.
The uncomfortable truth is that some of the best HR advice I’ve ever had came from people who’d built and run small teams themselves, not from people with the longest CV. Ask any prospective advisor whether they’ve run their own team of under 20 people. If the answer is no, it doesn’t disqualify them, but it should make you push harder on whether their advice is calibrated for your reality or for the one they came from.
Where to find advice you can trust
Three sources are worth more than most paid consultancies at the early stage.
First, peer groups of other small business owners at your exact size. I’ve had more useful HR answers in five minutes from a founder who’d just been through the same situation than from an hour with a paid consultant. Online communities built around live conversation, similar to how a well-run Twitter chat can surface sharp, practical answers fast because people are answering in the moment rather than selling you something, are underrated for this. If you’ve never seen what makes a Twitter chat useful for growing your audience, the same principle applies to finding candid HR advice: real-time peer answers beat polished sales calls.
Second, a fractional HR consultant who works specifically with businesses your size, paid by the hour or on a small monthly retainer, not a full agency contract. Ask for two client references at your headcount before you sign anything.
Third, staying current on how AI is changing HR admin, because a lot of the grunt work (drafting job descriptions, first-pass interview scheduling, writing initial disciplinary letters for a solicitor to check) can now be handled faster with the right tools. I cover this kind of shift regularly in my own AI roundups, including practical tool updates in the 2 August 2026 AI news roundup and the follow-up 9 August 2026 edition. None of this replaces judgement on a real dispute, but it can cut hours off the admin side so your paid HR advice goes toward the decisions that need a human.
Practical systems that make HR advice easier to act on
One small but real fix: if you’re constantly rescheduling interviews, probation reviews, or appraisal meetings by email back and forth, get a proper booking system in place. It sounds unrelated to HR advice until you realise how many small disputes start with “we never had that conversation” because a meeting kept slipping. If you’re not sure where to start, my guide on how to pick an online booking app for client appointments covers the same decision logic that applies to booking staff reviews: pick the simplest tool that gets used, not the one with the most features.
The same goes for training. If your HR advisor recommends a full onboarding programme with live sessions every week, ask whether that’s needed or whether it’s filling time. My piece on how many webinars you should run per month, and when zero is the right answer, was written about marketing content, but the same test applies to HR training: run it because it solves a real gap, not because it looks thorough on paper.
A simple way to check the advice you already have
If you’ve already got an HR advisor or a policy pack sitting in a drawer, run this quick test. Pick your three most likely near-term situations, something like an employee asking for flexible hours, a probation period that isn’t going well, and a minor conduct issue. Ask your current advisor what they’d do in each case, step by step, not what the policy says. If they can only quote the document back at you rather than talk through the judgement calls, you’ve got a document, not an advisor. That’s the difference that matters, and it’s the one thing worth checking before you renew any contract or pay another invoice.

Frequently asked questions
How much should HR advice cost for a small business?
For a business under 20 employees in the UK, expect £60 to £120 an hour for ad hoc fractional advice, or £200 to £600 a month for an ongoing retainer that includes handbook updates and support with occasional disputes. Full agency contracts pitched at this size are usually overpriced for what you’ll use.
Do I need an HR consultant or an employment solicitor?
You need an HR consultant for day-to-day policy, hiring practice, and performance management, and an employment solicitor specifically when a situation has real legal exposure, such as a formal grievance, a potential tribunal claim, or a redundancy process. Many small businesses keep a solicitor on standby rather than on retainer until headcount passes 20 to 30.
How do I know if HR advice is too generic for my business?
Ask your advisor to walk through a real, specific situation you’re likely to face, like a difficult probation review, step by step. If they can only point you back to a document rather than talk through what they’d do and why, the advice hasn’t been calibrated to your business.
What’s the biggest HR mistake growing small businesses make?
Buying a full policy pack or agency contract before they need one, then discovering it doesn’t match their actual size, sector, or way of working. It’s cheaper and safer to start with hourly, specific advice and build up your policies as real situations demand them, rather than paying upfront for documents built for a much bigger company.
