# Offboarding self-employed workers cleanly: a UK operator's checklist

Short answer. End the engagement on the terms in your agreement, remove app, system and site access the same day, close the final work record, and settle the final payment (by self-billed invoice if you self-bill), using a debit note for any later price change. Then recover kit with a dated condition log, take the person off rotas and substitute lists, and keep only the records you need for the periods HMRC sets, such as 6 years for company accounting records. Done in one sitting, it closes the file instead of leaving loose ends across spreadsheets and inboxes.

This is operational guidance, not legal or tax advice. Whether anyone is self-employed depends on the facts; see GOV.UK's employment status guidance and HMRC's CEST tool. Checked against the GOV.UK, legislation.gov.uk and ICO pages listed under Sources on 14 October 2026.

# Why a clean exit matters

Most offboarding problems are operational. Someone who has left still has a login. A van or scanner is "with someone". A last invoice is corrected by quietly cutting the next one, which never comes.

A clean exit also finishes the audit file. Our record-keeping guide describes the five parts of that file: engagement, documents, work record, pay and audit log. Offboarding is the point where each part gets its final entry.

The process below works the same for cleaning, facilities, care and field-service teams as for couriers. Whatever the reason the engagement ends, follow the agreement and keep the language accurate: you are ending the engagement as the agreement allows, and how the relationship is classed depends on the facts, not on the words you use.

# The offboarding checklist

# 1. Notice under the agreement

Check what your agreement says about ending the engagement: who can end it, how much notice, how it is given, and what happens to work already accepted. Follow it, put the end date in writing, and keep a copy on the file. Offer no further work after the end date.

# 2. Remove app, system and site access the same day

On the end date, remove:

• logins to your app and any client or network systems
• shared drives, group chats and email lists
• site access cards, gate codes and key safes
• fuel cards or accounts in your name

Record who removed each access and when. Under the UK GDPR, personal data must be processed with appropriate security, and leaving a former contractor with access to it works against that.

# 3. Close the final work record

List the work completed up to the end date, any accepted work that was not done, and anything still disputed. The final pay is built from this record, so agree it before you pay.

# 4. Final self-billed invoice and the agreement

If you self-bill, issue the final self-billed invoice from the closed work record in the normal way. VAT Notice 700/62 says a self-billing agreement runs for the period it specifies, and that self-billing terms in a contract last until the contract ends. Record the end date of the agreement on the file. If you later need to change the value of a supply you have already self-billed, the notice says to issue a debit note rather than reduce a later invoice; after an exit there may be no later invoice. You must not self-bill anyone at any time when you do not have their written agreement, so make sure the agreement's end date covers the final self-billed invoice and any debit note correcting it, and raise no self-bills after it has ended. Our guides to self-billing for subcontractor pay runs and HMRC self-billing for couriers cover the invoice rules.

# 5. Deductions only where the agreement allows them

Make deductions from the final payment only where the agreement provides for them, for example for unreturned kit, and show each one as a separate line with the reason. If the agreement does not cover it, raise it with the person rather than deducting it.

# 6. Recover kit and vehicles

List everything you supplied: devices, scanners, uniforms, keys, cards and any vehicle. For each item, record the date it came back, who received it, its condition and photos. Where something is not returned, record what was asked for and when.

# 7. Return or keep documents, for the right period

Decide what you return, what you keep and for how long.

These periods cover financial and right to work records. For other personal data, such as copies of licences, ID, insurance and contact details, the storage limitation principle applies: the ICO says you must not keep personal data for longer than you need it, should have a policy setting standard retention periods, and should periodically review what you hold and erase or anonymise it when no longer needed. Keep what the job and the law require, set a deletion date for the rest, and record it. The ICO notes that this guidance is under review following the Data (Use and Access) Act 2025.

If the person asks you to erase their data, the ICO explains the right to erasure. Article 17(3) says it does not apply to the extent that processing is necessary to comply with a legal obligation, which is why records you must keep for tax are treated differently from the rest.

# 8. Remove them from rotas and substitute lists

Take the person off future rotas and any pool of relief workers. Also check whether they were listed as a substitute for anyone else; our guide to managing substitutes covers how substitute records work, and the rota planning guide covers offering work.

Sign-off: whoever closes the file records their name, the date, and that steps 1 to 8 are complete.

# Re-engaging someone later

People often come back. Treat a return as a new engagement: a new agreement, a fresh status assessment against the new arrangement, and fresh document checks. That includes a new right to work check where the new engagement is in scope, because the rules extended to individual subcontractors who personally do work you have contracted to provide apply to engagements that start on or after 1 October 2026. The document re-check checklist sets out what to look at again. If you self-bill, VAT Notice 700/62 says you need a written agreement in place before self-billing starts, so agree a new one.

# Common mistakes

• Leaving logins live after the end date.
• Correcting the last invoice by "netting off" instead of issuing a debit note.
• Deducting for kit when the agreement does not provide for it.
• No condition log, so a disputed item comes down to memory.
• Keeping every document indefinitely "just in case", with no retention policy.
• Deleting financial records you still need to keep.
• Leaving the person on a substitute list or a rota template.

# How Zerity helps

Zerity is one operating system for compliance and operations across your self-employed workforce, so the file you close sits on one record:

• Every licence and policy expiry date is tracked in one place. Zerity stores the record, the date it was checked and the expiry; checking remains your duty, using the DVLA service or a bureau your insurer accepts.
• The self-billing agreement is stored, invoices are raised from the agreed rate and days worked, and the PDF is kept. The software does not make the arrangement compliant on its own.
• The rota is published to the driver app, and days worked feed the self-bill.
• Contracts, policies and handbooks are stored in one place, with version history, policy acknowledgement tracking and quick retrieval for audits.
• One account covers every site, with people tagged by depot and network.

Zerity does not decide anyone's employment status. See compliance software for self-employed workforces. Pricing is from £6 per active driver.

# Common questions

# How should a UK business end an engagement with a self-employed worker?

Follow the notice terms in your agreement and confirm the end date in writing. On that date, remove access, close the final work record, settle the final payment (by self-billed invoice if you self-bill), recover kit with a condition log, and take the person off rotas and substitute lists.

# Can I correct a final self-billed invoice after the person has left?

VAT Notice 700/62 says that to change the value of a supply you have already self-billed, you should issue a debit note rather than reduce a later invoice. After an exit there is usually no later invoice, so a debit note is the way to correct it.

# How long should I keep a former contractor's records?

GOV.UK says limited companies must keep accounting records for 6 years from the end of the last company financial year they relate to, and VAT Notice 700/21 says VAT records should generally be kept for at least 6 years. Other personal data should not be kept longer than you need it.

# Do I have to delete a former contractor's data if they ask?

Not always. Article 17 of the UK GDPR gives a right to erasure, but it does not apply to the extent that processing is necessary to comply with a legal obligation. Erase what you no longer need and record why you keep the rest.

# What should I check if someone comes back?

Treat it as a new engagement: a new agreement, a fresh status assessment against the new arrangement, current documents checked again, a new right to work check where it applies, and a new self-billing agreement before any self-billed invoice.
