You normally need to notify Acas for Early Conciliation before submitting an Employment Tribunal claim, and strict time limits usually apply—often three months less one day from the incident. If conciliation does not resolve the dispute, Acas issues a certificate so you can submit form ET1 online to HM Courts and Tribunals Service. A Leicester-area case may be listed at a suitable hearing centre, but HMCTS decides the arrangements. Check the current guidance on GOV.UK and consider advice from a solicitor regulated by the SRA, particularly if your deadline or claim type is unclear.
