How to Draft the Term of an Employment Agreement in the UK

The term of an employment agreement sounds simple, but it is one of the clauses that causes the most confusion for growing businesses. Founders often copy a fixed-term clause from an old template, forget to say when employment actually starts, or leave probation and notice periods saying different things in different parts of the contract. That creates uncertainty at exactly the wrong time, usually before you hire your first worker, before you renew a fixed-term arrangement, or before you try to end employment cleanly.

The problem is not just wording. In the UK, the term clause affects status, notice, holiday accrual, continuity of service, and the risk of an employee arguing that they were never truly on a short-term arrangement at all. A well-drafted clause makes the commercial deal clear and helps the rest of the contract work properly. This guide explains how to draft the term of an employment agreement, what UK businesses should check before they sign, and the common mistakes that lead to disputes later.

Overview

The term clause sets out when employment begins, whether it is permanent or fixed-term, how any probation period works, and when the arrangement ends or can be ended. If this clause is vague, the rest of the contract can become harder to enforce and much harder to manage in practice.

• State the employee's start date clearly, and distinguish it from any earlier date that counts towards continuous employment if relevant.
• Say whether the contract is permanent, fixed-term, or linked to a specific project, event, or period of cover.
• Set out the probation period, including whether it can be extended and what notice applies during probation.
• Make sure the term clause matches the notice clause, holiday wording, and any end date elsewhere in the agreement.
• For fixed-term contracts, explain what happens at the end of the term and avoid wording that accidentally promises renewal.
• Check that the arrangement reflects the reality of the working relationship before you classify someone as a contractor or temporary worker instead.

What This Means For Your Business

The practical meaning is simple: the term clause tells both sides when the employment relationship starts, how long it is expected to last, and how it may end. Before you sign, you want that answer to be precise, commercially sensible, and consistent with the rest of your paperwork.

For many SMEs, this issue comes up when a hire is not obviously permanent. You might be covering parental leave, recruiting for a 12 month grant-funded role, hiring for a seasonal spike, or bringing someone in to deliver a specific project. In each of those cases, the business intention matters, but the written contract still needs to say exactly what the parties have agreed.

In UK employment contracts, the term is not just an administrative detail. It helps determine how you manage probation, notice, benefits, and expectations around renewal. It also affects risk if the relationship continues beyond the stated end date.

Permanent employment

A permanent contract usually starts on a stated date and continues until either party ends it in line with the notice provisions. If that is what you intend, say so plainly. Avoid overcomplicating permanent employment with language that suggests a hidden review date or an automatic endpoint.

A clear permanent term usually includes:

• the employment start date
• whether there is a probation period
• the length of probation and whether it may be extended
• the notice position during and after probation

Fixed-term employment

A fixed-term contract is commonly used where the business need is temporary and identifiable. The term should either end on a specific date or on a specific event, such as the return of another employee from leave.

If you are using a fixed-term arrangement, the clause should make that basis clear. It should not read like a permanent contract with a date inserted at the top. The reason is practical. If the employee stays on, the wording around expiry, notice, and renewal may be tested later.

A fixed-term term clause often covers:

• the start date
• the end date, or the event that brings the contract to an end
• whether notice can be given before the end date
• whether the employee may be offered a further contract, without promising one

Probation periods and the term clause

Probation often sits close to the term clause because it affects the first stage of the relationship. Before you sign, make sure probation is drafted in a way that fits the actual hire. A six month probation with an extension right may be sensible for a senior role, but less so for a short fixed-term hire lasting only a few months.

Founders often trip up by putting one notice period in the probation clause and another in the termination clause, without saying which applies when. That creates room for argument. The safer approach is to make the interaction between term, probation, and termination rights explicit.

Continuous employment and previous service

The employee's start date is not always the same as the date from which continuous employment counts. For example, an employee may move within a group structure, or there may be earlier service that legally counts for continuity purposes. If that applies, the contract should distinguish those dates clearly.

This point matters because continuity can affect employment rights and entitlements. A vague clause can create confusion later, especially if the business assumes the employment relationship is newer than it really is.

Legal Issues To Check Before You Sign

The main legal task is to make sure the term clause reflects the real arrangement and works with the rest of the contract. Before you sign a contract, check the commercial plan first, then test whether the drafting says exactly the same thing.

1. Identify the real nature of the role

Start with the practical question: is this genuinely a permanent hire, a fixed-term employee, or something else entirely? Businesses sometimes use short contracts because they feel safer, but the label does not always change the legal reality. If the person is working like an employee and the role keeps rolling on, a fixed-term document may not solve the underlying risk.

This is where founders often get caught. They want flexibility, so they use a temporary form without considering whether the role is actually ongoing.

2. Use a clear start date

The contract should state the date employment begins. If there is an earlier date that counts towards continuity, record that separately. Do not rely on offer emails or verbal discussions to fill the gap.

Before you rely on a verbal promise, ask whether the written contract gives a complete answer on:

• when employment starts
• whether any previous service counts
• whether employment is subject to probation

3. Draft the fixed term precisely if there is one

If the role is fixed-term, the contract should say exactly how and when it ends. A date is usually easiest. If the end point depends on an event, define that event carefully, for example the return of the substantive post-holder from maternity leave.

Loose phrases such as “for approximately 12 months” can create uncertainty. If your business needs flexibility around timing, draft that carefully rather than leaving the end point vague.

4. Decide whether notice applies before the fixed term ends

Some businesses assume a fixed-term contract simply ends on the expiry date and that is the whole story. In practice, the contract should state whether either party can give notice before that date. If early termination is allowed, set out the notice required.

This matters because a fixed end date and a notice clause can point in different directions if they are not coordinated. Before you sign, make sure the agreement answers both questions:

• what happens on the stated end date
• what happens if either party wants the relationship to end earlier

5. Align probation wording with the term

If the contract includes probation, the drafting should explain how long it lasts, whether it can be extended, and what notice applies during that period. If the business can extend probation, say who decides and how that will be communicated.

A common drafting issue is silence around what happens if probation ends and no one says anything. Usually the contract should make it clear that employment continues subject to the ordinary terms unless the business notifies the employee otherwise.

6. Check statutory written particulars and contract consistency

Employers in the UK need to provide required written particulars of employment. The term clause should fit with those particulars and with the wider agreement. If the term says one thing and other provisions say another, the employee may argue that the ambiguity should be read in their favour.

Check consistency across:

• job title and role description
• hours and working pattern
• notice clause
• holiday year and holiday accrual wording
• garden leave or payment in lieu wording if used
• any policy references about probation or fixed-term renewal

7. Think about renewal and rollover risk

If a fixed-term contract may be renewed, avoid wording that sounds like a promise unless the business intends to make one. A better approach is to say the contract ends on the stated date unless the parties agree otherwise in writing.

That does not remove every risk, especially if the employee continues working after expiry, but it gives the business a clearer starting point. Before you let the end date pass, decide whether you will renew, replace the contract, or end the arrangement cleanly.

8. Consider discrimination and fairness issues

The term clause should not be drafted in a way that unfairly targets a worker for a protected reason, or creates arbitrary differences without thought. For example, if one person is repeatedly kept on short contracts while others in similar roles are permanent, that pattern may raise wider employment law questions.

The term wording alone is not the whole issue, but it is often where the paper trail starts.

Common Mistakes With How to Draft the Term of an Employment Agreement

The most common mistakes are not complicated legal theories. They are drafting shortcuts that seem harmless at the offer stage, then become expensive when the relationship changes or ends.

Using a template that does not match the hire

A startup may pull a contract from a previous role and swap out only the name and salary. The result is often a term clause that says “permanent” in one place, “12 month contract” in another, and includes a probation period that outlasts the intended fixed term.

Before you hire your first worker, check that the contract was actually drafted for this role and this business need.

Leaving the end date uncertain

If you use a fixed-term arrangement, uncertainty is a major problem. An end date described loosely, or an event defined badly, makes workforce planning harder and can trigger disputes about whether the contract truly expired.

Good drafting is specific. If the event is someone returning from leave, identify that role and the event clearly.

Confusing the start date with continuity of employment

Businesses sometimes treat the signing date, the first working day, and the continuous employment date as if they are the same. They may not be. If there has been a transfer, group move, or prior service that counts, record it properly.

This mistake often appears harmless until notice, redundancy, or eligibility for rights become relevant.

Forgetting that fixed-term staff are still employees

A fixed-term contract does not mean the person sits outside normal employment protections. Businesses sometimes act as though a short term means fewer obligations. That is risky.

The agreement still needs proper employment terms, and the business still needs to manage the relationship lawfully. The term clause should support that, not suggest the worker is somehow less engaged with the business.

Letting the contract expire on paper but continue in practice

This is a classic SME issue. The end date passes, the employee keeps working, payroll continues, and no one signs a renewal. At that point, the written term may no longer reflect reality.

Before the expiry date arrives, decide what happens next. If the role is continuing, update the paperwork. If it is ending, communicate that clearly and in good time.

Making promises about renewal

Managers sometimes reassure candidates by saying the contract will “definitely be extended” if things go well. If the written wording also hints at expected renewal, the business may later face arguments about what was promised.

Before you rely on informal discussions, make sure the contract says only what the business is prepared to commit to.

Not matching notice, probation and termination provisions

The term clause does not stand alone. If notice is one week during probation, one month afterwards, and the fixed-term clause says the contract simply ends automatically, those clauses need to fit together. If they do not, disputes become more likely when employment ends.

This is especially relevant before you sign with senior hires, project staff, and anyone replacing a worker on leave.

Using contractor language in an employee agreement

Some businesses try to preserve flexibility by mixing contractor concepts into an employment contract. That can create confusion over status, control, and rights. If the person is an employee, draft an employee agreement. If they are genuinely self-employed, use the right form of contract and assess status carefully.

Before you classify someone as a contractor, check the reality of the relationship, not just the label you would prefer.

FAQs

Should a UK employment contract always state a start date?

Yes. The agreement should clearly state when employment begins. If a different date applies for continuous employment, that should also be stated separately where relevant.

Can I use a fixed-term contract for any employee?

You can use a fixed-term contract where the role is genuinely temporary or tied to a clear project, period, or cover arrangement. The contract should reflect the real reason for the arrangement and should not be used carelessly as a substitute for proper workforce planning.

Does a fixed-term contract need a notice clause?

Usually, yes. The contract should say what happens if either party wants to end the arrangement before the agreed end date, and what happens when the term expires.

What happens if a fixed-term employee keeps working after the end date?

The written term may no longer reflect the actual arrangement. If the employee continues working, you should review the position quickly and update the contract or confirm the next steps in writing.

Can probation be longer than the fixed term?

It can be drafted that way, but it often makes little practical sense. The better approach is to make probation proportionate to the expected length and nature of the role.
