When a formal job offer creates a binding contract
In the world of HR, the disclaimer “subject to references” often appears in offer letters. Many employers treat it as an escape clause. They assume it allows them to withdraw an offer at any time before “Day One”. However, a recent ruling has firmly challenged that assumption. In fact, the tribunal clarified that a conditional offer can become legally binding. This applies even before an employee steps into the role. Consequently, employers must now recognise that a formal job offer creates a binding contract much earlier than they might expect.
The background: what happened in Mr Swamy’s case
Mr Swamy applied for the post of project manager. The company formally offered him the role. Notably, the offer was “subject to receipt of satisfactory references, a right-to-work (RTW) check, and a successful six-month probation period”. Mr Swamy then formally accepted the offer via email. He also provided contact details for his references. In addition, he submitted his RTW documents promptly.
Following this, Loesche Energy Systems Ltd (Loesche) advised Mr Swamy to secure a 12-month rental. This was because the role was initially based in the UK. As a result, Mr Swamy made significant personal and financial commitments.
The withdrawal: a sudden change of plans
Unfortunately, only weeks before his start date, Loesche contacted Mr Swamy. They informed him that their own client contract had been delayed. Therefore, they were “no longer able to offer” the position as specified. Understandably, Mr Swamy was left in a very difficult position. He had already reorganised his life around the role. Accordingly, he brought a claim for breach of contract. He argued that a binding agreement had already existed. Moreover, he believed this entitled him to notice pay.
The ruling: how the tribunal decided
The Appeal Tribunal sided with Mr Swamy. It found that the offer letter had contained all the essential terms. These included salary, hours, start date, and probation period. Crucially, a probation period can only begin after employment starts. Therefore, it was logical to view the entire package as a concluded contract. The tribunal determined that a formal job offer creates a binding contract once the candidate accepts it. Consequently, Loesche did not hold an unrestricted right to withdraw the offer. By failing to provide sufficient notice, they had effectively breached the contract.
The notice period: what counts as “reasonable”?
Interestingly, the written contract was silent on how much notice was required. As a result, the tribunal had to infer a term of “reasonable notice”. Loesche attempted to argue for a “zero-day” notice period. Alternatively, they suggested a statutory minimum of just one week. However, the tribunal rejected both arguments. Instead, it determined that three months was the only reasonable term. This conclusion reflected the fact that Loesche had asked Mr Swamy to secure a 12-month rental property. In other words, the employer’s own actions raised the bar for what “reasonable” meant.
Why this matters for employers and recruiters
This ruling carries significant weight for anyone involved in recruitment. Fundamentally, it confirms that a formal job offer creates a binding contract from the moment of acceptance. Employees now enjoy protection from “Day One” after they accept a clear offer. This is true even if onboarding checks remain in progress.
Furthermore, if an employer withdraws an offer for reasons unrelated to background checks, consequences will follow. For instance, a change in business fortunes does not justify withdrawing an accepted offer. In such cases, tribunals can award significant damages. These damages are typically based on an implied notice period.
What should employers do now?
In light of this case, employers should take several practical steps. First, they must rigorously review all offer letters and pre-employment correspondence. Additionally, they cannot rely on “standard terms” that the candidate has not actually seen. Equally, they should be explicit about notice periods during the pre-start phase.
Moreover, HR teams must understand that a formal job offer creates a binding contract once accepted. Therefore, internal processes should reflect this legal reality. For example, employers should ensure that withdrawal clauses are clearly drafted. They should also confirm that all conditions are genuinely assessed before issuing offers.
Ultimately, once a candidate accepts an offer, the employer crosses a legal “point of no return”. Ignoring this principle can lead to costly tribunal claims and reputational damage.
