Employee Leaving in the UK: Employer Checklist for Notice, Pay and Covenants

An employee leaving your business can feel like a disruption (especially in a small team), but it’s also a moment where getting the legal basics right can save you serious time, cost and stress later.

Whether the departure is friendly, sudden, or a bit awkward, the same core issues usually pop up: notice, handover, access to systems, company property, final pay, holiday, and what happens with post-employment restrictions like non-competes.

Below is a practical UK employer checklist you can use when you’re managing an employee leaving scenario. It’s written for small businesses, where you may not have a dedicated HR team, but still need a process that’s fair, consistent and legally sensible.

This article is general information only and isn’t legal advice. If you’re unsure about the right approach for your situation, it’s best to get tailored advice.

When You First Hear An Employee Is Leaving: The Immediate Checklist

The first 24–72 hours after you hear the news are where mistakes often happen. Your goal is to get clarity, document the key points, and reduce operational risk without overreacting.

1) Confirm How They’re Leaving (Resignation vs Termination)

Start by confirming the reason for the employee leaving:

• Resignation (they’re choosing to leave)
• Mutual exit (you’re agreeing a departure date together)
• Dismissal (capability, misconduct, redundancy, etc.)
• End of a fixed-term contract

Why this matters: each route affects notice, process, and risk. For example, dismissals can trigger unfair dismissal claims if you don’t follow a fair process (where the employee has the right qualifying service and the claim isn’t in an “automatic” category), while resignations usually place the focus on enforcing the contract correctly.

2) Get The Resignation In Writing (And Acknowledge It)

If it’s a resignation, ask for it in writing. This can be an email (it doesn’t need to be a formal letter in most cases), but it should clearly state:

• the intention to resign
• the intended last working day (or at least the date notice starts)

If the employee is asking how to word it, you can point them towards a basic approach (without dictating it). If it helps, here’s a resource on a resignation letter so you understand the typical format employees use.

Then you should acknowledge acceptance in writing and confirm the key terms (notice period, last day, handover expectations).

3) Pull Out The Contract And Policies Now (Not Later)

Don’t rely on memory. Find the signed employment contract and any relevant policies (handbook, commission scheme, bonus policy, IT policy).

If your documentation is patchy, treat this as a prompt to tighten things up for the rest of the team. A properly drafted Employment Contract is often the difference between a straightforward exit and weeks of negotiation.

4) Run A Quick Risk Check

Not every departure is high-risk. But some roles are more sensitive than others. Consider whether they:

• had access to confidential business information, pricing, strategy or financials
• managed key client relationships
• had admin access to systems, social accounts, CRMs or payment platforms
• worked in sales (and could target your pipeline)
• were trained at your expense

This risk check informs whether you should consider garden leave, tighter access controls, or reminders about confidentiality and restrictive covenants.

Notice Periods, Garden Leave And PILON: Getting The Exit Date Right

In most small businesses, notice and end dates are where misunderstandings start. The contract might say one thing, the employee expects another, and you’re left trying to cover shifts and client commitments.

1) Check The Contractual Notice Period (And The Statutory Minimum)

Notice periods can be:

• Contractual (what’s written in the contract)
• Statutory (the legal minimum, depending on length of service)

As a general rule, you should follow the contract, as long as it meets or exceeds statutory minimum notice. If you’re unsure (especially where the contract is silent or unclear), get advice before confirming dates in writing.

Also remember: notice obligations can vary depending on the reason for leaving. For example, redundancy has its own practical considerations around notice and timing. If redundancy is part of the picture, it’s worth checking redundancy notice periods so you’re aligned with the correct process.

2) Consider Garden Leave (Where It’s Allowed)

Garden leave means the employee remains employed and continues to be paid, but you require them to stay away from work (and usually not contact clients or staff) for some or all of their notice period.

Garden leave can make sense where the employee leaving creates a risk to your business, for example:

• they’re going to a competitor
• they could disrupt staff or client relationships
• they have access to sensitive information

Practical tip: it’s much easier to use garden leave when your contract includes a garden leave clause. If it doesn’t, you may still be able to agree it, but trying to impose it without a contractual right can create legal risk.

3) Pay In Lieu Of Notice (PILON): Check Your Contract First

PILON is when you end employment immediately and pay the employee what they would have earned during the notice period (or the remaining part of it).

From an employer perspective, PILON can be useful when:

• you need a clean break (for example, access/security concerns)
• the working relationship has broken down
• keeping them in the business during notice isn’t practical

But don’t assume you can always do it. Whether you can make a contractual PILON (and what it includes) depends on the wording of the employment contract and any applicable policies. If there’s no PILON clause, paying in lieu can still be possible, but it may be treated as a breach of contract (wrongful dismissal), and that can affect other rights you may want to rely on (including, in some cases, post-termination restrictions).

4) Probation Period Nuances

If the employee leaving is still on probation, the contract may have a shorter notice period and different exit mechanics.

It’s still worth being careful: probation doesn’t remove the need to act fairly or consistently (and it doesn’t remove discrimination risk). If you’re reviewing your approach, take a look at probation periods to sense-check your contract and process.

Managing Handover And Protecting Your Business (Clients, Systems, Property)

A smooth handover is partly operational, but there are important legal angles too: confidentiality, data protection, IP ownership, and avoiding disputes about what was (or wasn’t) handed back.

1) Put A Handover Plan In Writing

For a small business, a simple handover plan is often enough. Set out:

• key tasks/projects to finalise
• clients/accounts that need transition support
• logins, shared mailboxes, and system admin steps
• who the employee is handing over to, and by when
• any training required for the replacement or remaining staff

This protects you if the employee later claims they weren’t given clear expectations during notice, or if things fall through the cracks.

2) Control Access To Systems Early

You don’t need to treat every exit like a security incident, but it’s sensible to tighten access controls. Depending on the role, consider:

• changing shared passwords (especially admin passwords)
• removing access to sensitive folders and finance systems
• reviewing forwarding rules on email accounts
• planning when to revoke access (often at the end of the last working day)

If you monitor access or communications, make sure it’s done lawfully and transparently. This is an area where employers can accidentally create privacy risk if they “just check everything” without a proper policy and rationale.

3) Collect Company Property And Confirm Return In Writing

Make a simple company property checklist. Common items include:

• laptop/desktop and chargers
• mobile phone/SIM
• keys, fobs, access cards
• uniform and equipment
• company credit cards
• hard copy documents

If there’s any dispute later (for example, about “missing” equipment), a written record helps.

4) Be Careful With “Sign-Offs” And Documents

Sometimes exits involve signing paperwork (variation agreements, settlement terms, confirmations of deductions, reference wording, IP assignments, etc.). Make sure whoever signs for the company has authority, and the document is executed correctly.

If you’re unsure about what counts as a proper signature in a business context, check legal signature requirements so you don’t end up with an unenforceable document.

Final Pay, Holiday Pay And Deductions: Avoiding The Most Common Disputes

Final pay is one of the biggest sources of conflict when an employee is leaving. Usually it’s not because anyone is acting in bad faith-it’s because expectations weren’t spelled out early, or payroll is rushed.

1) What Should Final Pay Typically Include?

Final pay often includes:

• salary/wages up to the termination date
• payment for accrued but untaken holiday (unless holiday is taken during notice)
• overtime (if applicable and owed under contract/custom)
• commission earned under a commission scheme
• bonus (only if contractually owed-many bonuses are discretionary)
• approved expenses
• PILON (if applicable)

Be especially careful with commission and bonus arrangements. The details often depend on the scheme rules (for example, whether the employee must be employed at the payment date, or whether the sale must be fully invoiced/collected).

2) Holiday During Notice vs Holiday Paid Out

Employees often want to use up holiday during notice, and employers often prefer payout (or vice versa).

In the UK, holiday rules are driven by the Working Time Regulations 1998 and the employment contract/policies. Practically:

• If they take holiday during notice, you’ll usually pay them as normal for those days.
• If they have unused holiday remaining at the end, you’ll usually need to pay it out.

Tip for small businesses: confirm the holiday balance in writing early in the notice period so there are no surprises at payroll time.

3) Can You Deduct Money From Final Pay?

This is a common question, especially where the employee leaving has:

• not returned company property
• taken more holiday than accrued
• owed training costs
• caused damage or loss

In most cases, you shouldn’t make deductions unless you have a clear contractual right (or the employee’s written agreement). Unauthorised deductions can lead to wage claims.

If you use training cost repayment provisions, make sure the clause is drafted properly and used fairly-these can be enforceable in the right circumstances, but they’re not “one size fits all”. It’s worth reviewing training costs provisions if you’re relying on them regularly.

4) Issue The Right Documents

As part of the employee leaving process, you may need to provide:

• a payslip for the final pay period
• P45 (usually generated through payroll)
• confirmation of the termination date in writing
• reference (if you choose to provide one)

References are a whole topic on their own, but the key practical point is: keep them consistent, accurate, and avoid anything that could be misleading or retaliatory.

Restrictive Covenants, Confidentiality And IP: What You Can (And Can’t) Enforce

When an employee is leaving, many employers worry about clients being poached, staff being approached, or confidential information turning up in a competitor’s pitch deck.

The good news is you can protect your business-but you need to do it properly. Overreaching restrictions can be unenforceable, and heavy-handed tactics can escalate a situation unnecessarily.

1) Start With Confidentiality (It Often Matters More Than A Non-Compete)

Most employment contracts include confidentiality obligations during employment, and often ongoing obligations after employment ends.

As a practical step, consider sending a short “exit confirmation” email reminding the employee of:

• their confidentiality obligations
• return/deletion of company information
• restrictions on using client lists, pricing, and internal documents

This type of reminder can be very effective, particularly where the exit is amicable and the employee simply needs clarity.

2) Non-Competes And Non-Solicitation Clauses Need To Be Reasonable

Restrictive covenants (like non-compete, non-solicitation, and non-dealing clauses) are not automatically enforceable just because they’re in the contract.

They generally need to be:

• reasonable in time (there’s no “standard” period-it depends on the role and the risk you’re protecting against)
• reasonable in scope (what exactly is restricted?)
• reasonable geographically (if geography is relevant to the role)
• protecting a legitimate business interest (like confidential information, customer connections, or stability of the workforce)

If you’re using longer restraints (for example, 12 months), you should be especially careful about drafting and whether the restriction is justifiable for the role. For context, see how non-compete clauses are typically analysed from an employer risk perspective.

3) Protect Customer Relationships With A Clear Exit Plan

Legal clauses are only one side of the equation. The other side is relationship management. For key accounts, consider:

• introducing the replacement early
• moving key communications to shared inboxes
• documenting client status (pipeline, renewals, issues)
• ensuring CRM notes are up to date

This reduces the practical risk of client loss, even if you never need to enforce a restrictive covenant.

4) Make Sure IP Created By Employees Actually Belongs To Your Business

If the employee leaving created marketing materials, software, designs, written content, or internal documents, you’ll want to be confident those materials belong to the business and can be used after they go.

Many employment contracts deal with IP ownership, but not all do it well. If your team creates valuable materials, it’s worth getting the employment contract and IP clauses checked so you’re protected from day one.

Key Takeaways

• When an employee leaving situation arises, get the resignation/exit terms in writing early, and confirm the last working day clearly.
• Always check the employment contract for notice, garden leave, PILON, commission/bonus rules, and post-employment restrictions before you promise anything.
• Create a written handover plan and manage system access and company property return to reduce operational and security risk.
• Final pay disputes are common-confirm holiday balances, commission rules, and any deductions (only where lawful and documented) before payroll is processed.
• Restrictive covenants (non-compete, non-solicitation, non-dealing) can protect your business, but only if they’re reasonable and tailored to the employee’s role.
• If your contracts or policies are outdated, each employee exit is a useful prompt to tighten your legal foundations so the next departure is smoother.
