The order has fallen through, the budget has changed or a director has frozen recruitment. A manager wants to tell the new starter that their job offer is cancelled. Before sending that message, establish whether the business is withdrawing an outstanding offer or ending a contract that already exists. The difference matters even if the person has not worked a single shift. This guide focuses on that pre-start decision, rather than how to obtain references or run background checks.
Start with the full offer and acceptance record
GOV.UK confirms that accepting an unconditional job offer creates a legally binding employment contract. Neither the offer nor acceptance has to be written. A manager's telephone conversation followed by an email confirming the start date can therefore matter just as much as the formal document awaiting a signature.
Collect the advert, offer letter, emails, messages, notes of calls and any recruiter correspondence. Establish who said what, when the candidate accepted, which terms were agreed and whether anything remained genuinely unresolved. Do not use an unsigned contract as your only test of whether an agreement exists.
GOV.UK also explains that contractual terms can come from an offer letter, verbal agreement, handbook or implied terms. Check the whole record. A later template cannot safely be treated as proof that an earlier promise never happened. Where the accounts differ, record the disagreement and obtain advice before announcing a final decision.

Identify a genuine unmet condition—not a convenient label
A conditional offer depends on specified requirements, such as evidence of qualifications or satisfactory checks. Acas says an employer can withdraw it where those conditions are not met. If the applicant accepts and all conditions are fulfilled, however, the contract may already have started. Calling the letter 'conditional' does not keep the position open indefinitely.
List each condition alongside its actual status: outstanding, met or not met, with the supporting evidence. Separate a failed check from a check nobody has completed. A delay in obtaining information should trigger a practical review, not an invented adverse finding.
Most importantly, distinguish a problem with the applicant from a problem inside the business. If the customer cancels a project, that is not evidence that the candidate failed a reference condition. Do not re-label a commercial cancellation as an unsuccessful background check. Our separate reference guide covers handling missing or disputed reference information.

Treat a cancelled vacancy and an existing contract separately
Consider an illustrative Teesside engineering company that offers an administrator a role supporting a new contract. The applicant accepts an unconditional offer and resigns from their existing job. The customer then postpones the work. The company has a real commercial problem, but that does not erase its agreement with the applicant.
Managers should examine alternatives before deciding: can existing work justify the appointment, is another suitable vacancy available, or would the applicant voluntarily agree a revised start date? These are options to discuss, not changes to impose. Any agreement should be clear about the role, date, pay and other affected terms.
If the appointment cannot proceed, identify who will authorise the decision and who will review the contractual position. Acas advises that an unconditional offer should not simply be withdrawn without ending the contract fairly, giving notice and following its terms. Take specific advice where the agreement is fixed-term, unclear or disputed.
Review the offer before sending a cancellation email.

Discuss an offer withdrawalCheck notice and payment before promising that nothing is owed
Read the notice provisions, including any probation terms and any payment-in-lieu clause. Check how they apply before the agreed start date rather than assuming the normal payroll calculation answers the question. Do not describe the person as 'not yet employed' to bypass a binding contractual obligation.
Statutory minimum notice ordinarily applies once an employee has worked for the employer for at least one month. That threshold is not a licence to ignore contractual notice before work begins. Acas distinguishes the statutory minimum from notice agreed in the contract, statement or staff policy.
Ask the adviser reviewing the case to confirm the appropriate termination date, notice mechanism and payment calculation. Record any promised joining payment or relocation arrangement for review as well. Do not promise a standard week's pay as a universal settlement: the wording and facts determine the position.
Run a separate discrimination check
Discrimination law applies to recruitment decisions, including the terms offered and decisions not to appoint. A candidate does not have to complete probation before those protections matter. Acas warns that withdrawing either a conditional or unconditional offer because of pregnancy can be unlawful.
Pause if the proposed withdrawal follows disclosure of a disability, pregnancy or another protected characteristic. Ask whether the original reason is evidenced and consistently applied. Where disability affects the role, consider reasonable adjustments rather than treating a health disclosure as an automatic failed condition.
Keep equality-monitoring information separate from hiring decisions. A genuine budget reduction should have a contemporaneous business record; it should not first appear as an explanation after someone requests an adjustment. Obtain advice where commercial and protected-characteristic issues overlap.
Decision checklist before the withdrawal message
Explain the genuine reason and the next steps sensitively, then confirm the position in writing. Acas recommends explaining why an offer is being withdrawn. Nominate a contact for questions and acknowledge the practical impact on someone who may have resigned or rearranged childcare. Do not send inconsistent explanations through the recruiter and hiring manager.
For future appointments, use clear offer letters stating conditions, terms, start date, probation arrangements and the acceptance process. Limit who can make offers and confirm approval before managers telephone successful candidates. These are practical controls, not substitutes for reviewing the agreement already made.
Legal claims and official guidance checked on 16 October 2026. This guide addresses the current framework in Great Britain; Northern Ireland has separate employment legislation. It is general management guidance, not advice on an individual contract or claim.
- Confirm the offer's terms and whether, when and how it was accepted.
- Record every condition and distinguish outstanding checks from failed conditions.
- Identify the real reason and retain the evidence supporting it.
- Review contractual notice, termination wording and potential payments.
- Check discrimination risks and any reasonable-adjustment requirements.
- Consider workable alternatives without imposing a new agreement.
- Obtain senior approval and communicate the reviewed decision clearly.
Before withdrawing a job offer, establish whether a contract exists. A changed budget does not undo acceptance: check the conditions, notice, equality risks and communication before taking action.
