When you hire your first employee, finding an employment contract template online feels like the obvious shortcut. The problem is not the template itself - it is not knowing which fields are legal requirements, which clauses protect you, and which sections are placeholder text that will cause real problems if you do not customise them.
This guide covers what UK law actually requires you to include in an employment contract, what additional clauses are worth adding from a business protection standpoint, and where generic templates consistently fall short. Every section is written from your perspective as the employer - what you must do, and why it matters for your business.
What UK Law Requires: The Written Statement of Employment Particulars
The legal foundation here is the Employment Rights Act 1996, as amended. It requires you to provide a written statement of employment particulars to every employee and worker. This document is sometimes called a Section 1 statement, and it sets out the fundamental terms of the employment relationship.
Most employers conflate this with an employment contract, and in practice the two are usually combined into a single document. That is sensible. But the key point is that the written statement is a legal obligation - the employment contract is the wider framework that gives you enforceable protection beyond the statutory minimum.
Written Statement of Employment Particulars
The legally required document setting out the core terms of employment, prescribed by the Employment Rights Act 1996. Since April 2020, this must be provided on or before the employee's first day. It is not the same as a full employment contract, but in practice most employers issue both together.
The law specifies two categories of required information. The first is a principal statement, which must be a single document. The second is supplementary information, which can be contained in other documents - such as a staff handbook - provided they are referenced in the principal statement.
Day One Rights: What Must Be Given to Every Employee From the First Day
This is where many older templates and guides get it wrong. Before April 2020, employers had two months from the start date to provide the written statement. That deadline no longer applies. Since the Good Work Plan reforms took effect, the written statement must be provided on or before the employee's first day of work.
If you downloaded a contract template before 2020, or found one on a site that has not been updated, there is a meaningful risk it reflects the old two-month position. Check the guidance date before you use anything.
The principal statement - the single mandatory document - must contain all of the following on day one:
The employer's name and the employee's name
The start date and the date that continuous employment began (relevant if the employee is transferring from another employer)
Pay - the rate or method of calculation, and how often it is paid
Hours of work, including days of the week and whether hours or days may vary
Holiday entitlement and holiday pay, including accrual during the first year
Job title or a brief description of the work
Work location, or where the employee may be required to work
Probation period terms, including its length and any conditions
Any benefits - including non-pay benefits such as private medical cover or company car
Mandatory training requirements, including whether any are unpaid
The 2020 change applies to workers too, not just employees
Since April 2020, the day-one written statement requirement applies to workers - not only employees. If you engage people on zero-hours contracts, casual arrangements, or short-term engagements, you still have an obligation to issue a written statement from day one. Many templates do not reflect this.
Pay, Hours, and Holiday: Getting the Basics Right
The basics trip up more employers than the complex clauses do. Pay, hours, and holiday are the three areas where vague contract wording leads directly to disputes - and where tribunal claims are most likely if things go wrong.
Pay
State the gross annual salary or hourly rate explicitly. If pay will be reviewed annually, say so - but do not promise a specific increase, which creates a contractual obligation you may not be able to honour. Specify the payment frequency (monthly, weekly) and the payment method. If there is a discretionary bonus, use the word discretionary explicitly - a poorly worded bonus clause can become a contractual entitlement you cannot remove without the employee's consent.
Hours
State the standard working hours and working days. If your business requires flexible scheduling, include a clause permitting reasonable variation - but be specific about what that means. Ambiguity here creates disputes around overtime expectations and Working Time Regulations compliance. If the employee is expected to work more than 48 hours per week, you need a signed opt-out under the Working Time Regulations 1998.
Holiday
The statutory minimum is 5.6 weeks per year - which for a full-time employee working five days a week equates to 28 days. Employers may count bank holidays as part of this entitlement, but there is no separate statutory right to paid bank holidays. You can offer more, but you cannot offer less.
Specify whether bank holidays are included in or additional to the entitlement. State how accrual works in the first year. And set a clear holiday year - if you do not define one, disputes about carryover become much harder to manage.
Probation Periods: How to Write a Clause That Actually Works
The instinctive assumption about probation periods is that they give you a freer hand to end employment if things are not working out. That assumption requires careful qualification - and getting this wrong creates real legal exposure.
Currently, Currently, an employee needs two years of continuous employment before they can bring an ordinary unfair dismissal claim. However, the Employment Rights Act 2025 will reduce this qualifying period to six months for dismissals occurring on or after 1 January 2027.
However, the Employment Rights Act 2025 will reduce this qualifying period to six months for dismissals occurring on or after 1 January 2027. That protection does not currently apply during the first two years, which is why probation clauses have often been treated as low-risk. However, from 1 January 2027 the qualifying period reduces to six months under the Employment Rights Act 2025, significantly narrowing the window during which dismissal carries reduced legal exposure.
The risk is more specific than most employers realise - some types of dismissal, including those related to whistleblowing, pregnancy, or protected characteristics, carry no qualifying period. A poorly conducted probation dismissal can still expose you to discrimination claims or automatic unfair dismissal claims from day one.
Probation clause risk most employers underestimate
A probation clause that simply says 'employment is subject to satisfactory completion of a six-month probation period' without specifying what satisfactory means, or without following a fair review process, creates a document that is vague and a dismissal that may be poorly evidenced. You do not lose the two-year protection - but you increase your exposure if the employee has a protected characteristic or if you have not documented performance concerns properly. Always conduct a formal probation review and keep a written record.
A workable probation clause should specify the probation length (typically three or six months), the notice period during probation (which can be shorter than the post-probation notice period), and the possibility of extension. It should cross-reference your probation review process - which should be documented separately in a staff handbook or HR policy.
Confidentiality and Restrictive Covenants: What Small Employers Need to Know
Confidentiality clauses and restrictive covenants - sometimes called post-termination restrictions - are not required by law, but they are where small employers suffer the most commercially significant contract failures.
A generic confidentiality clause typically states that the employee must not disclose the employer's confidential information. That is fine as far as it goes. The problem is that for roles involving client relationships, pricing structures, supplier terms, or product knowledge, a clause that cannot define what is actually confidential is difficult to enforce.
Restrictive Covenants
Restrictive covenants are clauses that limit what an employee can do after they leave - typically preventing them from joining a direct competitor, poaching your clients, or recruiting your staff for a defined period. They are enforceable only if they are reasonable in scope, duration, and geographic reach - and only if they protect a legitimate business interest.
Generic templates often include blanket non-compete clauses covering 12 months and the whole of the UK. Courts apply those restrictively - overly broad covenants are frequently unenforceable. For most small employer situations, a targeted non-solicitation clause (preventing the employee from approaching your specific clients or key staff for six months) is more commercially useful and far more likely to hold up.
When to get a solicitor involved
If you are hiring someone with access to your client base, pricing, or proprietary processes - or if the role is senior enough that losing them to a competitor would cause real harm - do not rely on a generic template for the confidentiality and restriction sections. A short employment law review costs significantly less than an injunction application or the loss of a major client.
Notice Periods: Minimum Requirements and Why You Might Want More
Statutory minimum notice is one week after one month of continuous employment, rising by one week for each year of service up to a maximum of twelve weeks. These are the floor - your contract can go above them, but cannot go below.
For most early hires in a small business, a notice period of one month on both sides is a sensible starting point. The reason you may want more is not primarily about the employee giving you more time to hire a replacement - it is about giving yourself more time to manage a transition, protect client relationships, and limit the risk of the employee moving immediately to a competitor or taking clients with them.
If you include a longer notice period, consider whether to include a garden leave clause. Garden leave allows you to require the employee to remain at home during their notice period - still employed and still paid, but prevented from starting a new role or engaging with competitors. Without an express garden leave clause, you cannot compel an employee to take it.
What Generic Templates Often Get Wrong
Most problems with downloaded employment contract templates fall into four consistent categories. Knowing what to look for before you sign saves significant difficulty later.
Outdated day-one obligation. Templates created or last updated before April 2020 will reflect the old two-month window and may omit probation terms, training requirements, and benefits - all of which are now required in the principal statement from day one.
Vague or unenforceable restriction clauses. Blanket non-competes with no defined scope, geography, or legitimate interest backing them up. These look protective on paper but rarely stand up when you need them to.
Missing or ambiguous discretionary language on bonuses. A bonus described as 'performance-related' without the word 'discretionary' can become a contractual entitlement. Removing it later requires either the employee's consent or a payment in lieu.
No intellectual property assignment clause. For roles involving creative work, software, written content, or product development, you need an explicit clause assigning IP created during employment to the business. Some templates omit this entirely.
US-origin templates with inapplicable legal references. Some free online templates are drafted under US employment law and contain references to at-will employment and legal structures that have no application in the UK. These are not just irrelevant - they can create confusion about what the actual legal position is.
The IP clause omission
Illustrative example - based on a common UK founder scenario, not a specific documented case. A founder hires a web developer on a fixed-term contract using a generic template. The developer builds a bespoke platform that becomes central to the business. When the developer leaves, the absence of an IP assignment clause creates genuine ambiguity about who owns the code. The default legal position is not always as clear as founders assume - and resolving it costs considerably more than a properly drafted clause would have.
How to Use a Template Safely: The Checks to Run Before Signing
A template is a starting point, not a finished document. Before you issue any employment contract to a new hire, run through these checks.
Pre-signing contract checklist
Confirm the template has been updated to reflect the April 2020 day-one written statement requirement.
Check that all principal statement fields are completed - pay, hours, holiday, job title, location, probation terms, benefits, and training requirements.
Verify the holiday entitlement is 5.6 weeks minimum and that the holiday year is defined.
Confirm any bonus is explicitly described as discretionary if you intend it to be.
Review any restrictive covenants - are they time-limited, geographically defined, and targeted at a specific legitimate business interest?
Check the template includes an IP assignment clause if the role involves creative, technical, or product work.
Confirm notice periods meet the statutory minimum and include a garden leave clause if you have set a longer notice period.
Remove or replace any references to US employment law, at-will employment, or legal structures not applicable in the UK.
If the role involves access to confidential client data, pricing, or proprietary processes, have the confidentiality section reviewed by a qualified employment solicitor before issuing.
One further point worth being direct about: this article gives you a solid grounding in what UK employment contracts must contain and where templates typically fall short. It is not a substitute for legal advice. For standard roles at small businesses, a well-chosen and carefully customised template will usually serve you adequately. For senior hires, roles with significant confidentiality exposure, or any situation involving intellectual property or non-solicitation clauses that you actually intend to enforce, getting a qualified employment lawyer to review the contract before you issue it is a proportionate and practical step.
