Hiring Your First Employee

The true loaded cost of a first hire, and the five things you must set up to do it properly. A salary is not the whole cost: on top of it your company pays employer National Insurance and a workplace pension, with a worked example on a £30,000 salary and a setup checklist.

Mostly admin you set up once

Hiring your first employee feels like a cliff edge, but it is mostly admin you set up one time, then run each payday. The real surprise is the cost. A salary is not the whole cost: on top of it your company pays employer National Insurance and a minimum workplace pension contribution under auto-enrolment.

Good to know

Budget for more than the salary. A £30,000 hire is closer to £34,500 in real terms before the Employment Allowance is applied.

02Section

The true loaded cost, a worked example

On a £30,000 salary the company also pays employer National Insurance at 15% on pay above the £5,000 secondary threshold, plus a minimum 3% employer pension contribution on qualifying earnings. That is £3,750 of employer NI and £712.80 of pension on top, so the true cost is about £34,463, noticeably more than £30,000.

  • Employer NI: 15% of pay above the £5,000 secondary threshold, so £3,750 on a £30,000 salary.
  • Employer pension: a minimum 3% of qualifying earnings (£6,240 to £50,270), so £712.80 on a £30,000 salary.
  • The £10,500 Employment Allowance can offset some or all of the employer NI for eligible employers, bringing the cost back down towards £30,713.
Good to know

Eligibility rules apply to the Employment Allowance, including a restriction for sole-director companies with no other employees.

03Section

The five things you must set up

Get these five in place before the first payday and the rest is routine. Each is a legal duty and skipping one can be costly.

  • Register as an employer with HMRC for PAYE, before the first payday.
  • Run payroll and report in real time (RTI), sending HMRC a Full Payment Submission on or before each payday.
  • Set up a workplace pension and auto-enrol eligible staff, paying the 3% employer minimum.
  • Get employers’ liability insurance of at least £5 million and display the certificate.
  • Give a written statement of the main employment terms, on or before the first day of work.
Good to know

Employers’ liability insurance is not optional: you can be fined £2,500 for every day you are not properly insured.

04Section

The rules to know

Beyond the setup, a handful of ongoing rules govern what you pay and how you treat staff.

  • Pay at least the National Minimum or Living Wage: £12.71 for those aged 21 and over from April 2026.
  • Run a right-to-work check before employment starts and keep a copy of the evidence.
  • Give at least 5.6 weeks of paid holiday a year, which is 28 days for someone working five days a week.
  • Auto-enrol staff aged 22 to State Pension age earning over £10,000, and re-enrol eligible opt-outs roughly every three years.
Good to know

A compliant right-to-work check gives your company a statutory excuse against a penalty of up to £60,000 per illegal worker.

FAQ

Common questions

How much does it really cost to hire someone on £30,000?

More than £30,000. On top of the salary the company pays employer National Insurance at 15% on pay above the £5,000 secondary threshold (£3,750) and a minimum 3% pension on qualifying earnings (£712.80), so the true cost is about £34,463. The £10,500 Employment Allowance can offset some or all of the employer NI for eligible employers.

What do I have to set up before my first employee starts?

Five things: register as an employer for PAYE, set up payroll with real-time (RTI) reporting, set up a workplace pension and auto-enrol eligible staff, buy employers’ liability insurance of at least £5 million, and give a written statement of employment terms on or before day one.

Do I have to provide a pension for my first employee?

Yes, if they qualify. You must automatically enrol staff aged 22 to State Pension age who earn over £10,000 a year into a workplace pension and pay a minimum 3% employer contribution on their qualifying earnings.

Your first-employee setup checklist

Work through this before your new starter’s first day to make sure every legal duty is covered and the first payroll run goes smoothly.

  • Register as an employer for PAYE with HMRC before the first payday
  • Choose payroll software that handles RTI and pension deductions
  • Confirm the true loaded cost: salary plus employer NI plus pension
  • Check the salary meets the National Minimum or Living Wage
  • Claim the Employment Allowance if your company is eligible
  • Set up a workplace pension scheme before the start date
  • Auto-enrol staff aged 22 to State Pension age earning over £10,000
  • Budget the 3% employer minimum on qualifying earnings
  • Buy employers’ liability insurance of at least £5 million and display the certificate
  • Give a written statement of terms on or before day one
  • Run a right-to-work check and keep a copy of the evidence
  • Collect the new starter’s P45 or starter details for the tax code
  • Agree holiday: at least 5.6 weeks, up to 28 days a year
  • Send your first Full Payment Submission to HMRC on or before the first payday

Do it in order. Register for PAYE first, because the reference can take a little time to arrive, then layer on the pension, insurance and contract.
