Introduction

If you’re running a small UK business with a handful of employees, chances are you’re managing HR on a spreadsheet — and you might be doing just fine. A well-organised Excel or Google Sheets file handles basic holiday tracking, shift patterns and contact details without costing a penny.

But there comes a point where that spreadsheet quietly becomes a liability. Miss a right-to-work check, handle a subject access request badly, or lose track of overlapping absence types, and you’re looking at fines, tribunal exposure, or hours of firefighting you didn’t budget for.

This guide isn’t here to sell you software you don’t need. It’s here to help you work out honestly — based on headcount, turnover and complexity — whether a spreadsheet is still serving you or quietly creating risk.

What Spreadsheets Genuinely Handle Well

Let’s be fair to the spreadsheet first. For many micro-businesses it does the job.

Holiday tracking for small, stable teams. Fewer than five or six employees on standard hours? A shared spreadsheet tracks allowances, days taken and remaining entitlement without much trouble. A colour-coded calendar tab works fine and costs nothing.

Basic contact and emergency details. Names, addresses, next-of-kin, bank details in a password-protected file is manageable at very small scale. Not elegant, but workable.

Simple rota and shift planning. For a small café or a two-person trades business, a spreadsheet rota is quick to build and easy to share.

Ad hoc reporting. Need to tell your accountant how many people you employed last year? Minutes.

The honest threshold: if you employ four or fewer people on straightforward contracts with stable working patterns, a well-maintained spreadsheet is probably fine. Don’t let anyone frighten you into buying software you don’t need yet.

Where Spreadsheets Start Creating Real Problems

Several areas of UK employment and data protection law create obligations that spreadsheets handle poorly — not because they’re the wrong tool, but because they lack audit trails, access controls, automated alerts and compliance frameworks.

Statutory Record-Keeping

UK employers face several retention obligations:

• Payroll records — at least three years from the end of the tax year they relate to
• Working time records under the Working Time Regulations 1998 — two years
• Accident records under RIDDOR — at least three years

The problem isn’t that a spreadsheet can’t store this. It’s that a row is easy to delete, a file is easy to save over, and spreadsheets don’t log who changed what, or when. That missing audit trail becomes uncomfortable if a former employee raises a grievance or a tribunal claim, because your records are only as good as your ability to show they weren’t altered after the fact.

Check GOV.UK directly for the definitive position on record-keeping rather than relying on any summary, including this one.

GDPR and Employee Personal Data

Under UK GDPR, employees have rights over their personal data — access, rectification, erasure in some circumstances. As an employer you’re a data controller, and that carries real responsibilities.

Keeping sensitive employee data — health information, disciplinary records, bank details, National Insurance numbers — in a shared spreadsheet creates three specific risks:

• No access controls. If the file lives in a shared folder, everyone with folder access sees everything in it, including data they have no business need to see.
• No processing records. UK GDPR requires you to demonstrate how and why you process personal data. A spreadsheet gives you no record of who accessed what.
• No retention alerts. How will you remember to delete a former employee’s data once you’re past your retention period? The spreadsheet won’t remind you.

The Information Commissioner’s Office publishes detailed guidance on employment records and UK GDPR, and it’s worth reading if you haven’t.

Right-to-Work Checks

You must check every employee’s right to work before they start. The rules on acceptable documents and digital identity verification have become considerably more complex, particularly with the move to digital immigration status and share codes.

A spreadsheet can record that a check was done. It can’t store the evidence, alert you when a time-limited visa is approaching expiry, or give you anything resembling a compliance view.

The penalties are the reason this matters. Civil penalties for employing someone without the right to work run to up to £45,000 per worker for a first breach and up to £60,000 for repeat breaches, following an increase in 2024. Confirm the current figures on GOV.UK, as these have risen sharply and may rise again.

For an employer with even one person on a time-limited visa, an expiry date sitting in a spreadsheet cell that nobody is watching is a genuine exposure.

Overlapping Absence Types

This is the one that catches small businesses off guard. It starts simply — holiday, sickness — then compounds:

• Statutory Sick Pay eligibility and calculation
• Maternity, paternity, adoption and shared parental leave
• Pregnancy-related sickness, which must be recorded separately from ordinary sickness
• Neonatal care leave, a statutory entitlement since April 2025 for parents of babies requiring neonatal care
• Carer’s leave, a statutory right since April 2024
• Parental bereavement leave
• Emergency time off for dependants
• Fit notes, phased returns and reasonable adjustments

Each has different statutory rules, different pay triggers and different record-keeping requirements. Tracking them accurately across eight or ten employees with any turnover is genuinely difficult, and the risk of error — underpaying SSP, conflating pregnancy-related sickness with ordinary sickness, missing an entitlement altogether — grows with every additional person.

And the list keeps growing. Carer’s leave arrived in 2024, neonatal care leave in 2025, and UK employment law is currently in a period of substantial reform with further changes to sick pay and other entitlements being phased in. A spreadsheet doesn’t update itself when the law changes; software vendors push compliance updates as part of the subscription. Check the current position on GOV.UK, as this area is moving quickly.

The Tipping Point: When Does HR Software Make Sense?

There’s no magic number, but here’s a practical framework.

Stick with a spreadsheet if:

• You have four or fewer employees
• Contracts are simple and hours regular
• Staff turnover is very low
• No employees are on time-limited visas
• You’ve had no disciplinary, grievance or absence management issues

Start seriously considering software if:

• You employ five or more, or you’re growing towards it
• Anyone is on variable hours, zero-hours contracts or shift patterns
• You’ve had any turnover in the last 12 months, since onboarding and offboarding processes matter
• Any employee is on statutory leave of any kind
• You’ve received a subject access request from a current or former employee
• You can’t immediately say how many days’ holiday each employee has left

That last one is the honest test. If answering it takes more than thirty seconds, your spreadsheet is already costing you.

A reasonable rule of thumb: at around six to eight employees, the time spent maintaining spreadsheets accurately starts to cost more than a basic subscription. At ten or more, the compliance risk becomes hard to justify.

What HR Software Does That Spreadsheets Don’t

Even entry-level UK HR software typically provides:

• Self-service holiday requests with automatic entitlement calculations, including part-time and part-year pro-rating
• Absence management with separate tracking per leave type and SSP calculators
• Document storage with access controls, so only relevant people see sensitive data
• Right-to-work document storage with expiry alerts
• Audit trails showing who accessed or changed a record and when
• Retention settings with alerts when periods expire
• Onboarding checklists so nothing is missed with a new starter
• Reporting on headcount, absence rates and turnover
• Compliance updates applied automatically as legislation changes

Some platforms aimed at UK small businesses also integrate with payroll and accounting tools, reducing errors between systems.

A Note on Cost

UK HR software for small businesses typically starts at around £3–£7 per employee per month for basic plans, rising to £10–£15 for more comprehensive platforms.

For a concrete anchor: Sage HR starts from £5 per employee per month ex-VAT for its core module. For a team of eight, that’s £40 a month — roughly the cost of an hour of most business owners’ time.

That’s the calculation worth making. If maintaining your spreadsheet accurately takes more than an hour a month, the software has already paid for itself before you count the compliance benefit.

Note that pricing models differ, and it matters at this size. Per-employee pricing triples between three and nine employees; a flat company fee doesn’t. If you’re growing, ask which model you’re being quoted before comparing headline rates. Several providers also offer free plans for very small teams, which can be a useful stepping stone.

FAQ

Do I legally need HR software?

No. There’s no legal requirement to use it. What the law requires is that you maintain accurate records, handle personal data lawfully, conduct right-to-work checks and meet your statutory obligations on pay and leave. How you do that is up to you. The question is whether a spreadsheet lets you do it reliably as you grow.

Is a shared Google Sheet compliant with UK GDPR?

It can be, with careful setup — restricted access so only those with a legitimate need can view personal data, appropriate data processing agreements, and retention discipline. The honest answer for most small businesses is that a shared sheet holding employee personal data hasn’t been set up with UK GDPR fully in mind. The ICO’s guidance is the place to start.

What’s the cheapest HR software for a small UK team?

On confirmed pricing, Sage HR from £5 per employee per month ex-VAT — £25 for five people, £40 for eight. Several providers offer free tiers for very small teams, and some price a flat company fee rather than per employee, which works out better as you grow.

What’s the best HR software for UK small businesses?

Depends on team size, whether you need payroll integration, and budget. Commonly rated options include Sage HR, BrightHR, Breathe HR and Charlie HR. BrightHR is distinctive for bundling a UK employment law advice line on higher tiers, which is worth weighing if legal uncertainty is what’s driving the decision.

Can I use HR software just for holiday tracking?

Yes. Many platforms are modular. If holiday tracking and approvals are your pressing issue, a basic plan covering just that is a sensible start, with more added later.

Conclusion: Our Honest Recommendation

Spreadsheets aren’t the enemy. For very small, stable teams they’re a perfectly reasonable way to manage basic HR admin, and you shouldn’t feel pressured into buying software because it exists.

But the compliance landscape for UK employers is genuinely complex and getting more so. UK GDPR obligations, right-to-work penalties now reaching £60,000 per worker, an expanding list of statutory leave types, and ongoing employment law reform create real risk that a spreadsheet — however well-maintained — isn’t designed to manage.

Our practical recommendation: at five employees or fewer with straightforward arrangements, keep the spreadsheet but make sure it’s organised, access-controlled and reviewed regularly. At six or more, with any turnover or any form of complex absence, trial a basic platform — at around £5 per employee, the cost is unlikely to be what stops you.

The goal isn’t software for its own sake. It’s reducing risk, saving time, and meeting your obligations without losing a weekend to a spreadsheet audit.
