What HR Does a UK Startup Need From Day One - and What Can Wait?

Taking on a first employee is a big step for any small business. There’s suddenly more to think about than the job itself: pay, contracts, payroll, pensions, insurance, health and safety and the practicalities of keeping employee information secure.

It can be easy to go to one of two extremes. Some business owners put very little in place because the team is still tiny and everything feels informal. Others assume that becoming an employer means they now need the sort of HR set-up they remember from a much larger company. Neither approach is particularly helpful.

For a startup, the aim is to get the important foundations right without creating more structure than the business needs. The same applies to a small company that has been employing people for a while but still only has a handful of staff. If the original arrangements were put together quickly, this can be a good time to check whether they still fit the business as it operates now.

This post is for: startups taking on their first employee and small employers with only a handful of people who want to revisit the basics.

You’ll leave with: a practical view of what needs to be in place early, what can stay simple and what can reasonably wait until the business grows.

This post is not: a complete employment law audit or a reason to build a policy library before there’s a business need for one.

Start with the things that have to be right

Before somebody starts work, the business needs to be clear about the role, what they’ll be paid and the terms on which they’re joining. Employees and workers are entitled to a written statement of their main employment particulars, with the principal statement provided on or before the first day. In practice, a well-drafted contract will usually do more than simply meet that requirement. It should reflect what has actually been agreed about hours, place of work, holiday, sickness, notice, probation and any other terms that matter to the particular role.

Pay also needs checking rather than relying on a figure remembered from the last recruitment exercise. National Minimum Wage and National Living Wage rates change each April and the rate depends on age and, for apprentices, age and stage of apprenticeship. From 1 April 2026, the minimum hourly rates are £12.71 for workers aged 21 and over, £10.85 for those aged 18 to 20 and £8.00 for under-18s above compulsory school-leaving age and qualifying apprentices.

A right to work check is another essential before employment begins. The correct check depends on the individual’s circumstances and the evidence needs to be retained in the prescribed way. From 1 October 2026, the Right to Work Scheme is also being extended to some workers and individual subcontractors, not just employees. There are additional rules where work is supplied through another business or where a contractor is allowed to send somebody else in their place. For a startup using individual contractors, freelancers or subcontractors, it will be worth checking the arrangement against the new guidance rather than assuming the rules only apply to employees.

The business will also normally need to register as an employer with HMRC and run payroll. For many startups, the accountant or payroll provider will help with the mechanics but the owner still needs to make sure the information going in is right and that any changes to pay, hours or deductions are communicated in time.

Pensions, insurance and health and safety need a little more thought

Automatic enrolment duties start when the first member of staff starts work. The employer needs to assess the employee’s age and earnings to work out whether they must be put into a qualifying workplace pension. Broadly, staff aged from 22 up to State Pension age who earn more than £10,000 a year must normally be automatically enrolled, with contributions from both employer and employee. Staff who fall outside those criteria may still have the right to opt in or join, depending on their circumstances. The employer must write to staff about how automatic enrolment applies to them, keep monitoring age and earnings and complete a declaration of compliance with The Pensions Regulator within five months of the duties start date, even if nobody needs to be enrolled at the outset.

Employers’ Liability insurance is more straightforward. In most cases it is needed as soon as the business becomes an employer, and must provide at least £5 million of cover from an authorised insurer. For a startup that already has business insurance, the sensible first step is to speak to the existing insurer or broker before the employee starts and make sure the right cover is in place.

Health and safety can sound much bigger than it needs to be for a low-risk startup but there are still some basics to cover. The business should think through the significant risks in the work, decide what needs to be done to control them, make sure there are suitable first-aid arrangements and tell employees what they need to know. That may include workstation set-up for office or home workers, slips and trips, lone working, driving, manual handling, equipment or work-related stress, depending on the role. Every business needs a health and safety policy, although it only has to be written down once there are five or more employees. Risk assessments also need to be recorded once there are five or more employees. The amount of paperwork needed will depend on the risks involved in the work. A low-risk office business will need something very different from a business involving machinery, driving or manual work.

You probably don’t need an HR system on day one

With one or two employees, most businesses can manage perfectly well with a simple spreadsheet for holiday, sickness and key dates, together with secure employee folders for contracts, right to work evidence and other personal information. The important things are that records are accurate, access is restricted to the people who genuinely need it and personal information is properly protected.

Once the team reaches around five people, the admin often starts to feel different. Holiday requests overlap, sickness needs tracking properly and information begins to sit in several places. That’s often the point at which a basic HR system starts to earn its keep. Choosing something that can grow with the business is sensible but there is no need to switch on every feature from the beginning. Start with the parts that solve an immediate problem and add more functionality when the business is ready for it.

Be careful not to recreate the company you used to work for

Another way small businesses can make HR harder than it needs to be is by bringing in someone who’s spent most of their career in a much larger organisation and is keen to add more structure. The intention is usually good. They’re used to seeing a policy for almost every situation, formal approval routes and detailed processes, so that is what a well-run business looks like to them.

The problem is that a business with four or five employees doesn’t need to operate like one with four or five thousand. A full handbook can be extremely useful when the business reaches the point where employees and managers need one clear place to find the main rules and policies. Some customers may also ask to see particular policies as part of a tender or supplier due-diligence process. But that doesn’t mean every possible policy needs to be written before the first employee has finished their probation.

The better question is whether a document or process solves a real problem for the business now. If it helps people understand what’s expected, protects something important or makes a recurring task easier, it may be worth putting in place. If it exists only because somebody had one at a former employer, it can probably wait.

What if the first person you bring in is a freelancer or subcontractor?

Not every startup starts with an employee. It may make more sense to bring in a consultant, freelancer or subcontractor for a particular piece of work and that arrangement deserves proper thought too.

A good subcontractor agreement should describe the commercial relationship the business actually wants. It can set out the work or deliverables expected, how and when the contractor will be paid, responsibility for expenses, confidentiality, intellectual property, data protection, what happens if work needs correcting and how the arrangement can be ended. Depending on the work, insurance, liability and protection of customer relationships may matter too.

The agreement should also be consistent with a genuinely independent relationship. Somebody who is genuinely self-employed will usually have more control over how the work is carried out, take more financial responsibility for the work and operate their own business. A right of substitution may be relevant in some arrangements, as may the freedom to work for other clients, but putting those words into a contract won’t by itself make somebody self-employed. Employment status depends on the reality of the relationship and it should be reviewed if the way the parties work together changes over time.

What can wait - and how will you know when you need it?

The first version of HR in a small business is highly unlikely to be the finished version.

A full handbook may not be necessary when there are only one or two employees and the owner is still managing everyone directly. As more people join or managers begin making decisions themselves, having one clear place for the main policies and expectations can start to save time and reduce confusion. Some businesses will need particular policies sooner though because customers, tenders or industry requirements ask for them.

The same applies to systems. A spreadsheet and secure employee folders may work perfectly well at the beginning. Once holiday requests, sickness records and employee information become harder to keep on top of, moving to a basic HR system can make life much easier. Choosing one that can grow with the business means more features can be added when they’re genuinely useful rather than trying to implement everything on day one.

Other processes tend to follow the same pattern. Formal performance reviews, more detailed management guidance or additional policies usually become useful because the business has reached a point where informal arrangements are no longer enough. The trigger should be a genuine business need rather than a sense that a “proper” employer ought to have them.

If you already have a few employees, where should you look first?

A small business can stay small for quite a long time while the way it employs people gradually becomes more complicated.

The first contract may have been perfectly suitable when everyone worked the same hours from the same place but later hires may have brought different working patterns, commission arrangements or home working. Holiday and sickness might still be tracked in the spreadsheet set up for employee number one, even though the owner now spends too much time keeping it up to date. A contractor who originally came in for a specific project may now be working regularly alongside the team and looking much less independent than they did at the start.

The useful question is not whether the business needs “more HR”. It is whether any of the original arrangements are now creating extra work, uncertainty or risk.

That could mean updating contracts because working arrangements have changed, introducing a simple HR system because manual administration is becoming cumbersome, putting a few clearer policies in place because managers are now making decisions or reviewing a contractor arrangement because the reality no longer matches the agreement.

For a business with only a handful of employees, those adjustments are often enough. The aim is to deal with the areas that have stopped working well rather than rebuild everything from scratch.

Keep the first version simple

Good HR for a startup is not about looking like a large employer. It is about making sure the business can bring people in properly, pay and manage them correctly and keep enough structure around the relationship to avoid unnecessary problems.

Get the essentials right first. Keep the systems and processes simple while that’s still working well and add more structure when the business has a genuine reason for it.

That way, the HR arrangements stay appropriate for the size and stage of the business and can develop as the team grows.
