One Badge, Twelve Surprises: Hiring Employee Number One in the UK

There is a moment, usually about four weeks after you hire your first employee, when the badge printer has stopped being exciting and the paperwork has started to feel like a second job. The first hire is sold as a growth milestone. In practice, it is also the day you become an employer, a payroll contact, a pension administrator and, somehow, a manager.

At Start Network, we hear versions of the same story from founders across the UK. The work was fine. The person was great. The surprise was everything around the work.

The bit nobody warns you about: you are now a manager

Priya, a Manchester founder building a B2B software tool, hired her first operations lead in 2022 after months of freelancers and late-night spreadsheets. She expected the hiring conversation to be the hard part. It was not.

'The first week was lovely,' she says. 'The second week I realised I had no idea how to give feedback without sounding like I was reviewing a piece of code. I had gone from being the person who did everything to being the person who had to explain what everything was.'

That is the emotional whiplash. You are no longer just delegating tasks. You are setting standards, making judgement calls and quietly learning that 'flexible' means different things to different people. It helps to decide, before day one, what good looks like in the first 30, 60 and 90 days. Not a giant performance manual. A one-page plan is enough.

PAYE is not just a payroll setting

A common first-hire misconception is that payroll software handles everything. It handles calculations. It does not handle your obligations as an employer.

You generally need to register as an employer with HMRC before the first payday, and you will need an employer PAYE reference. Do this early. If you are hiring in a hurry, the last thing you want is a panicked call to an accountant on the Thursday before payday.

Tom, a Bristol founder who hired a developer in 2023, put it neatly: 'I thought PAYE was a button in the payroll tool. It turns out PAYE is a relationship with HMRC, and I had not introduced myself.'

Check the current thresholds and reporting dates with HMRC or your accountant rather than relying on a blog post. Tax rules move. Your payroll shouldn't be guesswork.

Pensions: auto-enrolment has a clock

Auto-enrolment is another area where founders often assume the pension provider will sort it. The provider runs the scheme. You still have duties as the employer.

You need to assess your workers, choose a pension scheme if you do not already have one, and communicate with staff within the relevant deadlines. The Pensions Regulator has clear guidance, and it is worth reading before your first payday rather than after.

One London founder we spoke to had a payroll provider, an accountant and a pension scheme, but no single person who had checked the auto-enrolment duties. 'It was the classic three suppliers, zero owners problem,' she said. Assign one person to own it. Ideally, that person is not also doing sales calls at 9pm.

Right to work: do it before day one

Right-to-work checks are not a box-ticking ritual to do when you remember. They need to happen before employment starts, and you need to keep evidence in line with Home Office guidance.

For British and Irish citizens, this is usually straightforward. For other employees, you may need to check a share code or specific documents. If someone has time-limited permission to work, you may need to repeat the check later. Build it into your onboarding checklist, not your 'when I get a minute' list.

This is also where a little awkwardness can save a lot of stress. Explain that the check is a standard part of onboarding. It is not a comment on the person. Good process protects both of you.

Probation and the contract: clarity beats vibes

A probation clause is not a substitute for good management, and a casual email is not a contract. UK employers generally need to give employees a written statement of employment particulars on or before day one. That statement should cover the basics: pay, hours, holiday, notice, probation terms, and where policies live.

Think about confidentiality, intellectual property and any restrictive covenants with proper advice. Templates can get you started. They should not be the final word on anything important.

Probation works best when everyone knows what it means. Is it three months or six? What review happens at the halfway point? What support is available? A clear probation clause gives you a structure. It does not give you permission to avoid feedback until the final week.

The first-hire checklist for 2026

Before you say yes, work through the boring bits:

• Confirm the role, salary, start date and notice period in writing.
• Register as an employer with HMRC and set up payroll before the first payday.
• Check current PAYE, National Insurance and minimum wage requirements.
• Choose a pension scheme and understand your auto-enrolment duties.
• Complete right-to-work checks before day one and keep records.
• Issue the written statement of employment particulars on or before day one.
• Put probation, review dates and feedback expectations in plain English.
• Sort equipment, accounts and access before the person starts.
• Decide who owns payroll, pensions and HR admin. Name a human.
• Book a 30-day check-in before the calendar fills up.

The hangover is normal

The first hire rarely feels like the clean growth moment that pitch decks suggest. It feels like a hundred small decisions, a few awkward conversations and a new identity you did not quite apply for.

That is not a sign you have done it wrong. It is a sign you have become an employer. The founders who handle it best are not the ones who know everything. They are the ones who ask the boring questions early, write things down and accept that managing people is a skill learned in public.

At Start Network, that is the version of growth we think is worth talking about: less hero founder, more human boss.
