Bringing someone into your team for the first time is a big milestone! exciting, a little nerve-wracking, and the start of a new set of responsibilities. Do it well and you gain capacity, capability and leverage. Do it badly and you’ll waste time, money and morale.

1. Get your head straight: why the first hire matters

Making a first time hire changes everything. Up to now you might have been able to flex and adapt quickly as a solo founder but a hired person relies on systems, clarity and fair treatment. Before you start recruiting, be honest about:

• What outcome you want this person to achieve in 90 days and 12 months.

• The real cost (not just salary) of taking them on.

• Who will manage them day-to-day and what time you will commit to training and feedback.

A clear brief prevents the common mistake of hiring for a job title rather than a business outcome.

2. Budgeting the real cost of your first hire

Salary is only the tip of the iceberg. When budgeting for a first time hire, include:

• Gross salary (offer you advertise).

• Employer National Insurance contributions (and any Employer NICs above thresholds). Employers need to know the current thresholds and rates when modelling costs.

• Pension employer contributions (auto-enrolment, see next section).

• Apprenticeship or training costs (if relevant).

• Recruitment costs (advertising, agency fees, interviewing time).

• Onboarding costs (equipment, licences, manager time).

• Notice period / redundancy risk (model worst-case exit costs).

A sensible rule: multiply the advertised salary by ~1.2–1.4 to capture on-costs for smaller businesses (use detailed figures for precise planning).

3. Legal must-dos before you employ anyone (pay attention here)

Right to work checks

You must check a candidate’s right to work in the UK before they start. Follow the Government’s step-by-step guidance: manual or digital checks are acceptable, but do them - it’s a legal requirement.

Employment contract & written statement

Provide a written statement of employment particulars (contract) on or before day 1 - hours, pay, holiday entitlement, notice periods, workplace, job title, and main duties. This is the baseline legal protection for both sides.

Minimum pay and statutory rates

Make sure you pay at least the National Minimum Wage / National Living Wage for the employee’s age group. The 2026 rates (effective from April 2026) include a National Living Wage of £12.71 for those 21+, with other age-banded rates for younger workers and apprentices. Check GOV.UK each April for updates.

Statutory Sick Pay (SSP)

From April 2026 SSP rules changed: SSP eligibility and rates have been updated so ensure your payroll handles SSP correctly; the SSP weekly rate for 2026–27 is set by the Government.

Holiday entitlement

Most full-time workers are entitled to at least 28 days’ paid leave (pro-rata for part-time). You can include bank holidays in this total or add them on top - but be explicit in the contract.

4. Pensions & Auto-enrolment

If someone meets the earnings and age thresholds, you must put them into a workplace pension and make employer contributions. The automatic enrolment earnings trigger has been retained at £10,000 for 2026/27, check the Pensions Regulator guidance and set up compliance before payroll starts.

Action: register as an employer with The Pensions Regulator, pick a scheme (or use NEST), and document your staging date / duty timeline.

5. Payroll, NICs and PAYE

You need a payroll process from day one:

• Register as an employer with HMRC for PAYE.

• Choose payroll software (Xero Payroll, QuickBooks, Sage, or payroll bureau).

• Understand Class 1 NIC thresholds for 2025/26 and 2026/27 and apply correct contributions. These affect both employee and employer obligations.

• Pay PAYE and NICs on time (RTI filing each payrun).

If you’re not confident, use an accountant or payroll bureau for the first few cycles while you build the internal competence.

6. Recruitment: hire for outcomes, not CVs

Write a short, outcome-driven job brief

Include:

• The one-sentence role purpose.

• Top 3 deliverables in the first 90 days.

• KPIs the person will be judged against.

• Core competencies and “deal-breakers”.

Where to find candidates

Use a mix of channels:

• Niche job boards and industry Slack/LinkedIn groups for specialised roles.

• Local colleges, apprenticeship hubs (if hiring a trainee or junior).

• Referrals from your network (the highest quality channel for many SMEs).

Interview process (practical, fast)

• Initial 30-minute phone screen to check fit and logistics.

• A practical task or case study (sensible, time-limited) that reflects real work.

• Panel interview with the direct manager and at least one colleague.

• Reference checks and right-to-work checks before offer.

Make prompt offers and be transparent on salary and progression - slow processes kill top candidates.

7. Practical tech and admin checklist

Make life easier (and compliant) by standardising the following before day-one:

• Payroll software and HMRC PAYE registration.

• Pension scheme set up and automatic enrolment checks.

• HR folder with template contract, holiday policy, sickness policy and handbook.

• Right-to-work checklist and ID verification process.

• Equipment procurement (laptop, access cards, software licences).

• Simple onboarding schedule and 90-day plan template.

A small admin investment up-front saves hours of firefighting later.

8. Common mistakes first-time hirers make

• Hiring for enthusiasm but not outcomes - write measurable deliverables first.

• Underestimating manager time - new hires need coaching; protect manager time each week.

• Skipping contracts or right-to-work checks - legal risk is real.

• Using vague pay structures - set salary, benefits and review cadence upfront.

• Neglecting pension and payroll setup - HMRC and The Pensions Regulator expect compliance from day one.

Think long-term, start simply

Hiring your first person is an investment in leverage. Start by being ruthlessly clear about what you need them to deliver, budget for the true cost, and get the legal and payroll basics right before day one.
