Acas Early Conciliation Extension: What Employers and Employees Need to Know

The New Timings

From 1 December 2025, the Acas Early Conciliation (EC) period, which currently allows up to six weeks for parties to attempt settlement before a tribunal claim is lodged, will be extended to a maximum of twelve (12) weeks.

This change will apply to all EC forms submitted on or after that date.

Why has this been introduced?

The Government has introduced this reform to relieve what it describes as “significant pressure” on Acas services, which have been struggling to manage rising demand for employment disputes from employees.

Recently, Acas have been inundated with claims, and the impact of this is undermining its effectiveness and compromising parties’ ability to engage in meaningful resolution prior to Tribunal proceedings.

For example, employers are now often only receiving notification of claims days before the end of the EC process, with some people even receiving the first contact with Acas after the EC period has ended (and the employee now able to issue a claim in the Employment Tribunal).

Conciliators are frequently appointed at the last minute, leaving little opportunity for meaningful discussions and some parties have noted that Acas have been reluctant to extend conciliation beyond the initial four weeks (Acas are able to extend the early conciliation process by a further two weeks currently, to a maximum of six weeks), citing excessive caseloads.

Impact on Employees

By extending the time period, employees will gain additional time to negotiate and potentially secure a settlement without the stress of issuing and proceeding to the Employment Tribunal.

However, for those employee’s keen to proceed quickly to the tribunal, this extension could mean longer waits before their cases can progress.

Many employees are already facing significant delays in having their claims heard and extending the Acas process risks compounding that problem.

Impact on Employers

For employers, the extension might avoid the expense and reputational risk of defending claims in the Employment Tribunal. The Government has also suggested that the impact on businesses will be low and offset by the savings associated with increased conciliation.

However, employers will now face the problem that it could take months, and in some cases up to a year once tribunal limitation periods are extended to six months, before they even learn that an employee intends to bring a claim.

By that time, relevant employees may have left and memories of events may have faded, making it harder to defend allegations.

The uncertainty created by this extended process may weigh heavily on HR teams and managers, who will need to strengthen record-keeping and internal processes.

Our thoughts

Ultimately, the extension of the EC period may offer more breathing space and opportunities for negotiation and settlement between parties. However, employers and employees should prepare for longer timelines, greater uncertainty, and the possibility that disputes will remain unresolved until they reach the Employment Tribunal stage.
