Garden Leave UK: Complete Guide 2025/26

Garden leave is one of the most commonly misunderstood aspects of UK employment law. For senior professionals in finance, legal, technology, and other competitive industries, garden leave arrangements can involve significant sums of money and months of restricted activity. This guide explains what garden leave means, your rights during it, and how employers and employees can negotiate the terms.

What Is Garden Leave?

Garden leave is a period during which an employee is instructed by their employer not to attend work, not to access company systems, and not to engage with clients or colleagues — while remaining on the payroll at full pay. The employee is technically still employed throughout the notice period. The name is said to derive from the notion that the employee can tend to their garden rather than working, though the term is now standard employment law jargon.

Employers typically use garden leave when: an employee has given notice to join a direct competitor; the employee has access to sensitive commercial information, client lists, or proprietary strategies; the employer wants to prevent the employee from immediately serving a competing business; or the employer wants to preserve the integrity of ongoing transactions or client relationships during a handover period.

Employee Rights During Garden Leave

During garden leave, you retain all your employment rights. Your employer must continue to pay your full contractual salary on the normal payment date. All contractual benefits must continue: if you have a company car, it must remain available; if you have private health insurance, it must continue; pension contributions must be maintained. Your holiday entitlement accrues at the normal rate — and you can take holiday during garden leave (though the employer can require notice of holidays as usual).

The period of garden leave counts as continuous employment for the purpose of all statutory rights. You continue to be entitled to protection from unfair dismissal, and your length of service increases throughout the period. If your employer tries to stop paying you during garden leave, this is a serious breach of contract that entitles you to treat yourself as constructively dismissed.

Restrictions During Garden Leave

The main restriction during garden leave is that you cannot work for another employer — particularly not a competitor — without your current employer's written consent. You remain bound by all express and implied contractual terms: confidentiality obligations remain in full force; duties of good faith and fidelity continue; you may not solicit clients or seek to entice colleagues to leave.

An employer who discovers that an employee on garden leave has started working for a competitor can apply to court for an injunction to enforce the garden leave clause. In cases where the breach is serious, damages may also be sought. High Court injunctions in garden leave cases have become increasingly common in financial services and technology, where the value of confidential information is high.

Non-Compete Clauses: They Start at the END of Garden Leave

This is the most important timing point that employees often misunderstand. Post-termination restrictive covenants — including non-compete, non-dealing, and non-solicitation clauses — run from the date employment actually ends. If you begin garden leave on 1 March 2026 with a six-month notice period, your employment ends on 1 September 2026. A six-month non-compete then runs until 1 March 2027 — a full year after you were sent home.

This is a deliberate feature of garden leave as an employer protection mechanism. Employers combine garden leave and non-compete clauses precisely to extend the period during which a departing employee cannot benefit a competitor. Courts acknowledge this effect but will refuse to enforce arrangements that, taken together, are unreasonable in scope, duration, or geographical area.

The courts assess enforceability of restrictive covenants at the time the contract was signed, not at the time of the breach. A restriction reasonable for a senior professional in a niche financial market may be entirely unreasonable — and therefore unenforceable — for a more junior employee or in a less specialised industry. Non-competes longer than 12 months are almost never enforced in UK employment law; 3-6 months is generally considered the outer boundary of what courts will uphold.

Negotiating Early Release from Garden Leave

Many employees on garden leave want to leave early — particularly if their new employer is ready for them to start. Early release is entirely possible if both parties agree. The current employer will typically agree to release if: the employee's new employer agrees to pay out the remaining garden leave salary (called a "buy-out"); the current employer receives confirmation that no confidential information will be used; and both parties sign a settlement agreement that includes a waiver of claims.

From the employer's perspective, accepting a buy-out from the incoming employer is sensible: they are compensated for the remaining notice period and reduce the ongoing obligation to pay salary for a non-working employee. From the employee's perspective, an early start at a new employer accelerates career progression and potentially means they do not have to rely solely on garden leave pay during the intervening period.

Settlement negotiations around early release typically involve employment solicitors on both sides and can be completed in as little as one to two weeks. Any settlement agreement must be in writing, the employee must receive independent legal advice (paid for by the employer), and the agreement must specifically identify the claims being waived.

What If the Employer Breaches the Garden Leave Terms?

If an employer stops paying during garden leave, reduces the employee's salary, removes benefits, or otherwise commits a repudiatory breach of the employment contract, the employee has options. The employee may accept the repudiatory breach and treat themselves as constructively dismissed — which preserves their claims for unfair constructive dismissal (if they have sufficient qualifying service) and wrongful dismissal (breach of contract). Alternatively, the employee may affirm the contract and bring a claim for the specific losses suffered.

Importantly, if the employer commits a repudiatory breach of contract, any post-termination restrictive covenants may become unenforceable. An employee released from their contractual obligations by the employer's breach is also released from the burden of those restrictions. This principle provides significant leverage in negotiations, and is why employers are generally very careful to maintain all payments and benefits during garden leave.

Garden Leave vs PILON: The Key Differences

Garden leave and payment in lieu of notice (PILON) both result in an employee leaving immediately without working, but they are legally distinct. During garden leave, the employment continues: salary and benefits are paid as they fall due, the employee accrues service, and the restrictions on working for competitors are grounded in the ongoing employment relationship. With PILON, the employment terminates immediately: the employee receives a lump sum equivalent to the notice pay, the employment ends on the day of payment, and any post-termination restrictions start running from that date.

From a tax perspective, garden leave pay is ordinary employment income subject to PAYE. PILON is also fully taxable since April 2018. However, an employee on garden leave continues to accrue pension contributions and other benefits that a one-off PILON payment would not include. For higher earners on long notice periods, the aggregate value of continued benefits during garden leave can be substantial.
