What are outsourced HR services?
Outsourced HR services mean an external team of HR professionals runs some or all of your HR for a monthly fee, instead of you employing an HR department. At Infinity HR that covers recruitment, payroll, absence and performance management, employee relations and dismissals, delivered by a named, CIPD-qualified consultant, set up within 48 hours, with no lock-in contract.
Payroll is the most commonly outsourced HR activity, followed by specialist advice (CIPD). Most small businesses start there, then hand over more as they grow. Only need day-to-day advice? See our HR support for small businesses. Want to know the cost first? Read our guide to HR outsourcing costs.

Who is outsourced HR for?
Outsourced HR works for UK businesses of every size that don't want to employ a full HR department. What you need changes as you grow:
1–10 employees
Small Business
Your first hires bring legal duties from day one: written terms, right-to-work checks, holiday, sickness and a fair disciplinary process. We put the essentials in place and are on call when something goes wrong.
11–50 employees
Growing Business
Recurring HR work arrives: recruitment, absence patterns, performance issues and the first difficult dismissals. We take the day-to-day work off your managers and keep your policies current.
51–200+ employees
Established Business
You need a full HR function without the headcount: payroll, performance frameworks, restructures and reporting. We run it as your outsourced HR department, scaling as you grow.
See what's included at each size on our pricing page.
Outsourced HR vs in-house HR
An honest comparison. For most businesses under 50 staff outsourcing wins on cost and cover; an in-house HR person wins on being physically present.
| Outsourced HR | In-house HR | |
|---|---|---|
| Cost structure | Fixed monthly fee that scales with headcount | Full salary plus employer NI, pension, training and software |
| Range of expertise | A team covering employment law, payroll, recruitment and ER | One person's experience, however good |
| Holiday and sickness cover | Always someone available | HR stops when your HR person is away |
| Employment law updates | Tracked and applied for you | Depends on your HR person's own training |
| Being on site every day | Remote-first, with visits when needed | Physically present, which suits large single-site teams |

Outsourced HR services: common questions
What HR services can be outsourced?
Almost all of them. Payroll is the most commonly outsourced HR activity, followed by specialist advice (CIPD, HR outsourcing factsheet). Beyond that, businesses outsource recruitment, contracts and handbooks, absence and performance management, disciplinaries, grievances and dismissals, or the entire HR function. You choose what to hand over; decisions about your people stay with you.
How much does it cost to outsource HR services?
In the UK, small businesses typically pay from around £200 a month for basic outsourced HR to about £800 a month for a comprehensive package, while pay-as-you-go HR support runs at roughly £60–£80 an hour (Startups.co.uk, March 2026). See our full guide to HR outsourcing costs, or our plans by business size.
Is it cheaper to outsource HR?
For most businesses under about 50 staff, yes. A monthly outsourcing retainer costs a fraction of a full-time HR salary once employer National Insurance, pension, training and software are added, and you are not paying for capacity in quiet months. Larger businesses with constant HR workload sometimes find a hybrid works best: an in-house HR administrator backed by outsourced specialist advice.
What are the disadvantages of outsourcing HR?
Your HR provider is not in the building every day, and a poor provider can feel like a call centre that does not know your business. You also remain responsible for the decisions made. That is why we give every client a named, CIPD-qualified consultant who learns your business, rather than a rotating helpline.
How quickly can you take over our HR?
We can usually have your HR support set up within 48 hours of signing up. For an urgent issue, such as a disciplinary hearing or a tribunal claim, we can give telephone guidance before onboarding is complete. Book a free consultation to start.
Will we be tied into a long contract?
No. We work on a fixed monthly fee with no lock-in contract, so we have to keep earning your business every month.
