Permanent Employment Contract in the UK: What Employers and Employees Need to Know

A permanent employment contract is an open-ended agreement between an employer and an employee with no fixed end date. Employment continues until either party ends it through resignation, redundancy, or dismissal. It is the most common form of employment in the UK and is associated with greater job security and a fuller range of statutory rights than other arrangements.

Under UK law, an employment contract does not have to be written to be legally valid. However, employers are legally required under the Employment Rights Act 1996 to provide a written statement of particulars from day one of employment. In practice, this statement and the employment contract are usually the same document.

Understanding the different employment contract types available in the UK helps both employers and employees choose the right arrangement and understand their respective rights.

Open-ended contracts with no defined end date. Employees accumulate statutory rights over time, including unfair dismissal protection after two years of continuous service (reducing to six months from 1 January 2027 under the Employment Rights Act 2025), statutory redundancy pay, and enhanced notice entitlements.

Fixed-term contracts run for a defined period or until a specific project is completed. Under the Fixed-term Employees Regulations 2002, fixed-term employees cannot be treated less favourably than comparable permanent employees without objective justification. Employees on successive fixed-term contracts for four or more years become permanent unless the employer can objectively justify the continued use of fixed-term arrangements.

No guaranteed minimum hours. The employer offers work as needed, and the worker can accept or decline. Zero-hours workers are entitled to the National Living Wage, paid holiday, and other basic statutory rights, but lack the continuity of employment that permanent staff accrue.

Part-time employees are entitled to the same terms and conditions as full-time employees on a pro-rata basis under the Part-Time Workers Regulations 2000.

Freelancers operate under a contract for services rather than a contract of employment, placing them outside most statutory employment protections. The distinction carries significant tax implications under the IR35 rules.

Under the Employment Rights Act 1996, a written statement must include the following from day one:

• Employer and employee names and addresses
• Start date and the date continuous employment began
• Rate of pay and pay frequency
• Working hours, days, and whether these may vary
• Location of work
• Job title or a brief description of the role
• Holiday entitlement, including public holidays
• Probationary period, including its conditions and duration
• Details of any training entitlement provided by the employer

Beyond the statutory minimum, a well-drafted contract should also address:

• Confidentiality obligations covering business information and client data
• Intellectual property clauses assigning work created during employment to the employer
• Restrictive covenants limiting what the employee can do after leaving
• Sick pay provisions, distinguishing statutory sick pay from any enhanced company scheme
• Bonus or commission arrangements, including calculation methodology and payment timing
• Grievance and disciplinary procedures, or a reference to where these can be found

Employer responsibilities include paying the agreed salary on time at no less than the National Living Wage, maintaining a safe working environment under the Health and Safety at Work Act 1974, not discriminating under the Equality Act 2010, and following a fair process before dismissing an employee with two or more years of service.

Employee rights on permanent contracts include protection from unfair dismissal after two years (reducing to six months from 1 January 2027), statutory redundancy pay, a minimum of 5.6 weeks' paid holiday per year, statutory sick pay, and the right to request flexible working from day one following the Employment Relations (Flexible Working) Act 2023.

Statutory sick pay (SSP) became payable from the first day of sickness absence from 6 April 2026 under the Employment Rights Act 2025, at a rate of £123.25 per week or 80% of average weekly earnings (whichever is lower). The previous three waiting days and lower earnings threshold of £125 per week were abolished. Workers must meet eligibility criteria, including being classed as employed for tax purposes and having started work with their employer. Further details on statutory sick pay eligibility and rates are available from ACAS.

Employee responsibilities include performing their role with reasonable care and skill, following reasonable workplace policies, maintaining confidentiality, and giving the contractual or statutory notice period on resignation.

Some clauses in permanent contracts deserve particular scrutiny from employees before they sign.

Probationary periods. Most permanent contracts include a probationary period, typically three to six months, during which reduced notice periods apply and the employer retains greater flexibility to end the relationship. Employees should be aware that unfair dismissal protection does not generally apply during this period if they have less than two years' service.

Restrictive covenants. Non-compete and non-solicitation clauses restrict what an employee can do after leaving. UK courts will only enforce these where they are reasonable in scope, duration, and geography. An overly broad restrictive covenant may be unenforceable, but it can still cause uncertainty and expense if challenged. Employees should read these carefully and, if necessary, seek advice before accepting.

Variation clauses. Many contracts include a clause allowing the employer to make reasonable changes to terms and conditions. As noted in our guide to employee contract amendments, these clauses must be exercised reasonably and do not give employers unlimited flexibility to change contractual terms unilaterally.

Garden leave. Some contracts include garden leave provisions, allowing the employer to require the employee to stay away from work during their notice period while continuing to pay them. This is typically used to protect confidential information or client relationships during a sensitive transition.

"A verbal contract is not a real contract."

In UK law, a verbal employment contract is legally binding. The requirement for a written statement does not invalidate verbal agreements — it simply means the employer must confirm the terms in writing. That said, a verbal contract is much harder to enforce when terms are disputed.

"I can be dismissed at any time if I am still in my probation period."

Employers can end employment during a probationary period with shorter notice, but they must still follow a fair process and cannot dismiss for a discriminatory reason, regardless of length of service.

"My employer cannot change my contract once it has been signed."

Contracts can be amended, but only with mutual agreement or through a valid flexibility clause exercised reasonably. Unilateral changes imposed by an employer without consent can constitute a breach of contract.

"Zero-hours workers have no employment rights."

Zero-hours workers have significant statutory rights, including the right to the National Living Wage, paid holiday, and protection from discrimination. What they typically lack is the continuity of employment that builds additional protections over time.

Negotiation is more common and more acceptable than many employees assume, particularly when switching employers or joining at a senior level.

What is typically negotiable:

• Base salary and bonus arrangements
• Notice periods on both sides
• Remote or flexible working arrangements
• Scope and duration of restrictive covenants
• Specific benefits such as pension contributions, private healthcare, or car allowance

How to approach it: Research the market rate for the role before entering negotiations. Be specific about what you are asking for and why. Raise concerns about restrictive covenants or other clauses calmly and professionally — most employers expect some negotiation and are willing to make reasonable adjustments.

If you are unsure about the legal implications of any clause, a one-hour consultation with an employment solicitor is a modest investment compared to the potential consequences of signing something you do not fully understand.

Once terms are agreed, the contract needs to be executed and stored. Traditionally this meant printing, signing by hand, scanning, and filing — a process that introduces delays, particularly when hiring remotely or across multiple locations.

A permanent employment contract is not just a formality. It is the legal foundation of the employment relationship, and its quality determines how clearly rights and obligations are understood by both parties from day one.

For employers, a well-drafted contract reduces the risk of disputes and provides a clear framework for managing performance, change, and exits. For employees, understanding what you are signing protects your interests and ensures you can enforce your rights if needed.

Taking the time to get contracts right at the outset — and to execute and store them properly — is one of the most straightforward risk management steps any business can take.
