A first aid at work or emergency first aid at work certificate is only valid for 3 years. To maintain your qualification as a workplace first aider, it’s crucial to complete a requalification first aid course before your certificate expires. Despite the certificate’s three-year validity, skills can deteriorate after just 6 months, a phenomenon known as skill fade. Recognising this, the HSE strongly recommends that first aiders undergo an annual refresher of their first aid skills.”
