England & Wales use an entirely electronic system (via Atlantic Data) to apply for disclosures. Northern Ireland similarly have an electronic system (provided by Access Northern Ireland). Volunteers in Scotland (using Disclosure Scotland) and British Scouting Overseas (BSO) are only able to used paper based systems to apply for disclosures.
In order to take into account the extra delays these paper based systems create, individuals in England, Wales and Northern Ireland have 30 days before becoming liable for mandatory suspension, where volunteers in Scotland and BSO have 60 days.
