How Much Does Outsourced HR Cost in the UK?

If you’re thinking about outsourcing your HR, one of the first questions on your mind is probably “How much does outsourced HR cost UK?”
It’s a fair question — and the honest answer is that it depends on your business size, the level of support you need, and how you choose to work with your HR provider.

At The HR Booth, we believe in being completely transparent about pricing, so you know exactly what you’re paying for and why. Here’s a breakdown of the factors that influence cost, along with ballpark figures to help you plan.

Your business size and number of employees

The more employees you have, the more HR requirements you’re likely to face.

  • Small businesses (under 20 staff) often need occasional advice and compliance support.
  • Medium businesses (20–100 staff) usually require a mix of reactive and proactive HR help, including employee engagement, recruitment, and policy development.
  • Larger SMEs (100+ staff) tend to need ongoing strategic HR management alongside day-to-day issues.

Generally, the bigger the headcount, the higher the HR time requirement — and the higher the outsourced HR cost UK.

Type of service: Retainer vs Pay-As-You-Go

You can choose between:

  • Retainer agreements – a set monthly fee for a defined number of hours or services. This gives you predictable budgeting and priority response times. Retainers can start from around £150–£500 per month for small businesses, increasing with complexity and staff numbers.

  • Pay-as-you-go services – charged hourly or per project. Rates typically range from £60–£125 per hour. This works well for one-off issues or seasonal needs but may be less cost-effective if you need regular support.

Level of support

The depth of support you need will influence outsourced hr cost UK. Some businesses just want legal essentials, while others want a partner to help with culture, growth, and strategy.

Basic compliance packages – from around £500

Designed for smaller businesses or those with simple needs. Typically includes:

  • Tailored contracts and policies
  • A basic staff handbook
  • Advice on day-to-day queries
  • Legal updates and templates

This provides peace of mind that you’re covered and compliant, without ongoing strategic input.

Full-service Outsourced HR Cost – £160–£600+ per month

Suited to growing SMEs or businesses that want HR to play a proactive role. This can include:

  • Compliance plus hands-on case support
  • Performance and appraisal systems
  • Recruitment and onboarding
  • Manager training and coaching
  • Employee engagement and wellbeing initiatives

This option goes beyond staying legal — it’s about building a stronger, more productive workplace.

Example:

  • 10 staff: compliance support £159+/month
  • 50 staff: proactive, full-service HR £450+/month
  • 100+ staff: comprehensive HR partnership £500+

Specialist HR projects

Some HR needs fall outside day-to-day operations, for example:

  • Redundancy management
  • TUPE transfers
  • Certificate of Sponsorship
  • Complex disciplinary or grievance cases

These are usually quoted separately due to the additional expertise and time required.
