Garden leave enforceability in UK sales contracts in 2026

Garden leave is the practice of paying an employee through their notice period while requiring them not to work. UK case law on garden leave enforceability has evolved over the past 30 years; the 2026 position is settled but specific.

This piece walks through when garden leave is enforceable in UK sales contracts, when it isn't, and how it interacts with post-employment restrictive covenants.

What garden leave does

When an employee gives notice (or the employer terminates with notice), the employer pays the employee through the notice period but does not require - or permit - the employee to come into work. The employee retains all employment status, contractual benefits, and remuneration during the period; the employer retains the employee's exclusive services.

For sales hires, garden leave matters because:

• It keeps a departing AE out of competitor hands during the notice window
• It protects customer relationships during the handover
• It allows the employer to debrief the AE's pipeline and territory before competitive activity resumes

When garden leave is enforceable

UK courts will enforce garden leave when:

1. The contract permits it. Most modern UK employment contracts contain an express garden-leave clause. Where the contract is silent, the employer's right to require garden leave is debatable; explicit drafting is preferable.

2. The duration is reasonable. Garden leave for the contractual notice period is generally enforceable. Garden leave that effectively extends the notice period (because the employee was already on garden leave when notice was given) is more contestable.

3. The employee continues to receive full contractual remuneration. Salary, bonus accrual, benefits, and (depending on plan terms) commission must continue. Withholding any of these during garden leave breaks the bargain and undermines enforceability.

4. The employer has a legitimate interest in requiring it. Customer-relationship protection, confidential-information protection, workforce-stability protection - the same legitimate-interest framework that applies to restrictive covenants.

When garden leave is not enforceable

Three failure modes:

Excessive duration. Garden leave for periods materially longer than the contractual notice period (or beyond what the legitimate interest justifies) faces challenge. UK courts have, in various cases over the past 30 years, declined to enforce garden leave where the duration appears to extend beyond protective necessity.

Withheld remuneration. Garden leave with reduced pay, withheld bonus, suspended commission accrual, or removed benefits is at high risk. The arrangement starts to look like a partial termination rather than continued employment, which undermines the contractual basis.

No legitimate interest. Garden leave applied as punishment, or to inconvenience the employee, or for purposes unrelated to legitimate business protection, is unenforceable.

How garden leave interacts with restrictive covenants

This is where 2026 practice has tightened. UK courts increasingly resist 'covenant-stacking': garden leave plus a separate post-employment restrictive covenant period, where the combined duration exceeds what the legitimate interest requires.

The principle: the legitimate interest determines the total period of restriction, not the contractual mechanism. An employer cannot stack a 6-month garden leave period on top of a 12-month non-compete to achieve 18 months of effective restriction if the legitimate interest only justifies 12 months.

Most modern UK employment contracts now include a 'set-off' clause: time spent on garden leave counts against the duration of post-employment restrictive covenants. The set-off makes the combined arrangement more defensible.

Drafting garden leave clauses that hold up

Six elements of defensible UK garden leave drafting in 2026:

1. Express right to require garden leave at the employer's discretion during the notice period
2. Defined duration linked to the notice period (do not extend beyond)
3. Continued contractual remuneration including bonus / commission accrual (with specific commission-on-departure wording)
4. Express prohibitions during garden leave: not contacting customers, not contacting employees, not undertaking other employment
5. Set-off against post-employment restrictive covenants: time spent on garden leave counts against covenant duration
6. Mutual agreement that the employment continues (avoiding inadvertent termination characterisation)

What to operationalise

For UK sales employers:

1. Audit existing employment-contract garden leave clauses. Confirm the six elements above. Where missing, redraft at the next renewal opportunity.
2. Apply garden leave on departure where the legitimate interest justifies it. Do not apply it routinely; courts increasingly require justification.
3. Document the legitimate interest at the moment garden leave is invoked. Customer-relationship protection, pipeline-handover requirement, confidential-information protection.

For UK sales employees:

1. Read the garden leave clause at offer stage. Negotiate set-off against post-employment restrictive covenants if not present.
2. During garden leave, observe the contractual prohibitions strictly. Breach undermines the employee's position in any subsequent restrictive-covenant dispute.
3. Where garden leave appears excessive or otherwise abusive, get specialist employment-law advice. Tribunals and courts have remedies; the cost of advice is small relative to the impact.
