What Is Outsourced HR and Is It Right for Your Business?
If you happen to run a growing business, there's a good chance you have worn the HR hat at some point, Sunday night spent drafting a contract, googling whether a probation extension is even allowed, or having the kind of difficult conversation that keeps you up afterwards. For a while, it works. And then, usually around the 20-to-50 employee mark, it quietly stops working. That's where you start asking the obvious question: Do you hire someone in-house, or is there a smarter way?
At JourneyHR, we have run practical experiments trying to answer exactly that question for forward-thinking businesses, as specialists in the realm of People and Culture. We believe that establishing any kind of HR resource function shouldn't be just a box-ticking exercise bolted onto the business’s operations; it should be a big, worthwhile commercial advantage. So, let's honestly talk about what outsourced HR is, what it costs, where it goes wrong, and how to know whether it's the right fit for any kind of business.
What Is Outsourced HR?
Outsourced HR means bringing in an external partner to manage some or all of your people function, rather than building a full in-house team. All things that can easily be managed with a well-oiled HR setup in place. In practice, outsourced HR services in the UK can cover everything from the day-to-day, including contracts, policies, employee queries, onboarding, right through to the strategic side- organisational design, change management, leadership development, and reward strategy.
It is never a one-size-fits-all, and it shouldn't be forced into that either. Some businesses want a fully outsourced people team that becomes an extension of their own. Others just need a trusted advisor on speed dial for the tricky moments. Good HR outsourcing flexes to your size, your stage, and your culture, which is precisely the point.
The model has moved firmly into the mainstream. The global HR outsourcing and consultancy market grew from around $53.8 billion in 2024 to an estimated $58.69 billion in 2025, and is forecast to reach $81.71 billion by 2029, according to The Business Research Company. This isn't a fringe choice anymore; it's how many productive, well-run businesses now access expertise. At JourneyHR, skilled professionals bring up important conversations related to HR and its field. Having had 16 years of hands-on experience in this sector, they now see the need for small and medium-sized enterprises (SMEs) to tap into expertise in a more flexible way.
Why More UK Businesses Are Outsourcing Their HR
There was a time when outsourced HR was often seen as a cost-cutting measure, something that was avoided to cut back on hiring costs. But now that's changed. Today, businesses outsource because it gives them access to senior expertise. Expert professionals such as Aliya Vigor-Robertson, the founding partner of JourneyHR, also share their unique perspective on the future of HR. Similarly, two major forces are driving the shift, and both are worth understanding before a business makes any decision.
The rising cost of getting people's decisions wrong
Employment law in the UK is getting more complex, not less, and the financial stakes are climbing with it. In 2024-25, more than 42,000 single claims were filed with the employment tribunal, a 23% increase year-on-year according to Ministry of Justice figures. For unfair dismissal claims that reached an award in 2023-24, the average compensation was around £14,000, with the British Chambers of Commerce putting the average all-in cost of a tribunal claim at roughly £8,500, and that's before you factor in management time, legal fees, and the sheer distraction of it all.
The risk profile is about to change again. Under the Employment Rights Act 2025, the qualifying period for unfair dismissal is being significantly reduced, the time limit for bringing many claims is set to extend from three to six months, and the cap on unfair dismissal compensation is due to be removed entirely. In simple terms, more employees will be able to bring claims, they'll have longer to do it, and the potential payouts will be larger. Every performance conversation, probation decision, and dismissal carries more weight than it did even a year ago. This is exactly where having an experienced HR partner pays for itself. Getting one disciplinary process right or settling one grievance well before it escalates can save many times the annual cost of the support.
The hidden cost of doing HR yourself
The other cost is quieter, but just as real: your time. Research by NerdWallet UK, based on a survey of 500 UK business owners, found that HR and team coordination eats up around 7.3 hours of leadership time every week, roughly 21% of the working week, at an estimated cost of nearly £19,000 a year. The Centre for Economic and Business Research has separately estimated that small firms can lose as much as 28 hours a week to admin and red tape.
Now ask yourself what that time is worth when it's spent on sales, product, or strategy instead of chasing emergency contact forms. This is why at JourneyHR, professionals like Sue Shaw talk about the burnout effect on both businesses and founders in relation to the world of HR. That gap between what a founder's time is worth and what they're actually spending it on is the real argument for outsourcing.
HR Outsourcing for Small Businesses: What It Looks Like in Practice
There's a persistent myth that a business needs to be a certain size before HR support is "worth it." We'd gently push back on that. HR outsourcing for small businesses is often where it makes the most commercial sense, precisely because a small team can't justify or afford a full-time HR Director, yet still faces every one of the same legal and cultural challenges a larger company does.
For a business of roughly 25 to 200 people, an outsourced model can be a genuine game-changer. You get HR Director-level thinking on the strategic decisions, and capable consultants and assistants to handle everything else, all without the overheads, recruitment costs, and risk of building a department from scratch.
Bountiful Cow: An apt example comes from one of our own clients, the media agency Bountiful Cow. Their CEO, Adam Foley, described the impact like this: that JourneyHR have become "invaluable as trusted advisors," sitting on the senior management team while also nailing the day-to-day functional basics, and that their forward-thinking, innovative approach even helped the agency craft "one of the best benefits packages in the business”.The fear leaders often have about outsourcing is that they will get a faceless helpline and generic templates. Done well, it's the opposite: a partner who knows your founders by name, understands your commercial pressures, and brings proactivity, empathy, and strategic counsel to the table. The size of your company stops being a ceiling on the quality of HR you can access.
The Different Models of Outsourced HR Support
One of the reasons outsourcing has grown as an option is that it's no longer all-or-nothing. At JourneyHR, we deliberately built several engagement models so businesses can choose the level of support that genuinely fits and change it as they grow. Here's how the main options tend to work.
Retained HR team
This is the closest thing to having your own HR team. We become your HR team in person and remotely, partnering with you on day-to-day people practices without the heavy overheads of permanent hires. You get the strategic horsepower of an HR Director paired with consultants and assistants who deliver the everyday work. For SMEs scaling quickly, retained HR support is often the SME sweet spot: predictable cost, senior expertise, and a team that's already up to speed when something urgent lands.
Client Collective
For businesses with smaller budgets, a lighter-touch retained service gives you monthly remote advice and support through a dedicated HR inbox, with fast response times for the day-to-day employee questions and challenges that crop up. It's a brilliant safety net for leaders who mostly cope, but don't want to be alone when something tricky appears.
Project work
Sometimes you don't need ongoing support; you need a specific job done well. For a fixed fee, an outsourced partner can deliver a defined brief: an organisational restructure, a new appraisal system, gender pay gap reporting, an engagement survey, or a management training programme. This is ideal for in-house teams who are stretched or businesses that need extra firepower for a one-off.
Pay as you go and bulk hours.
For the truly ad hoc, some clients simply want expert advice on tap without being tied into a retainer guidance on a performance issue, a long-term absence, or a live grievance. At JourneyHR, this is charged at a transparent hourly rate, with discounted bulk-hour packages for those who use it regularly. No surprises, no lock-in.
The common thread across all of these is flexibility. You shouldn't have to over-buy HR to get good HR.
Is Outsourced HR Right for Your Business?
Outsourcing isn't automatically the right answer for everyone, and we'd never pretend it is. But there are some reliable signs that it's worth a serious conversation. You might recognise a few of these:
You're spending leadership time on people admin instead of on growth, and it's starting to grate.
You've hit a tricky situation, a grievance, a potential dismissal, a restructure, and realised you're not confident you're handling it correctly.
You're scaling fast, and your informal "we just sort it out" approach is creaking under the weight of more people.
You can't justify a full-time hire yet, but you clearly need more than ad hoc Googling.
You have an in-house HR person who's overwhelmed and needs senior backup or extra hands on specific projects.
Compliance is keeping you up at night, particularly with employment law changes on the horizon.
If two or three of those ring true, outsourcing is almost certainly worth exploring. And the honest counterpoint: if you're a very large organisation with complex, high-volume HR needs across multiple sites, a fully in-house team may serve you better, though even then, many supplement with external specialists for change, employee relations, and leadership development.
Why Choose an Outsourced HR Consultancy in London?
Location still matters, even in a remote-friendly world. Working with an outsourced HR consultancy in London gives you a partner who understands the pace, talent market, and regulatory environment that London and UK-based businesses operate in and who can be in the room when it counts. Our own preference at JourneyHR has always been to build relationships in person where we can, because the best people advice comes from genuinely understanding a business, not just reading its policies.
We were founded in 2010 by Aliya Vigor-Robertson and Sue Shaw on a simple belief: that forward-thinking businesses deserve a flexible, commercially-savvy way to access People + Culture experts. We've grown almost entirely through word of mouth, working with brilliant businesses across the creative, media, and professional sectors. That word-of-mouth growth tells you something important about outsourced HR done properly: it's a relationship business, and reputation is everything.
Making the Decision
Here's our genuinely impartial take. Outsourced HR is right for your business when the cost of not having expert people support in risk, in lost time, in missed culture-building, outweighs the cost of bringing a partner in. For most growing SMEs in the UK, that tipping point arrives earlier than they expect.
The goal isn't to hand off responsibility for your people; it's to get better at looking after them, with experts beside you. Great HR isn't overhead. It's how you attract, keep, and get the best from the people who'll determine whether your business thrives.
If you're weighing it up and want a straightforward, no-pressure conversation about what would actually fit your business, we'd love to hear from you. That's the kind of conversation we have every day, and there's no commitment in simply exploring it.
FAQs
How much does outsourced HR cost in the UK?
Outsourced HR costs in the UK vary depending on the model you choose. Pay-as-you-go advice is typically charged at an hourly rate, fixed-fee project work is priced against a defined brief, and retained support is usually a monthly fee based on your headcount and the level of expertise you need. As a rule of thumb, outsourced HR is designed to cost less than a full-time hire while giving you access to more senior expertise. Many SMEs find that a retained arrangement works out more commercially sound than employing a standalone HR Manager.
What's the difference between outsourced HR and an HR software platform?
HR software helps you manage processes, holidays, records, and payroll data, but it can't give you judgment. An outsourced HR partner brings the human expertise: how to handle a grievance fairly, whether a dismissal is legally sound, how to design a reward strategy, or lead a restructure with care. Most businesses benefit from both: software for the admin, and people experts for the decisions that carry real risk and consequence.
When should a business start outsourcing its HR?
There's no magic headcount, but common triggers include reaching around 15–25 employees, hitting a difficult employee situation you're unsure how to handle, scaling quickly, or finding that leadership time is being swallowed by people admin. If HR is causing you stress, or you're worried about getting compliance wrong, that's usually the signal that expert support would pay for itself.
Can we outsource only part of our HR rather than all of it?
Absolutely. Outsourcing is flexible by design. You might keep an in-house HR person for day-to-day matters and bring in an external partner only for specialist projects like change management, employee relations, or leadership development, or vice versa. The right setup is whatever gives your business the cover it needs without paying for support it doesn't.
