The Environment Agency (EA) and the Department for Environment, Food and Rural Affairs have published guidance setting out the requirements for registering and deregistering polychlorinated biphenyl (PCB) equipment in England through an online service, explaining that holders must re‑register their equipment annually by 31 July until it is no longer held and must deregister it once it has been disposed of or decontaminated. The guidance specifies that applicants must provide authorised contact details and relevant organisational information, and, for registration, detailed technical and location data for each item, including unique identifiers, siting details, estimated oil quantities and substance concentration where known. For deregistration, applicants must additionally provide information on disposal or decontamination methods and dates, confirm whether the site has been sold, and submit supporting evidence such as waste transfer documentation or laboratory reports. It further explains that fees vary according to the number of items and sites, that invoices will be issued to a nominated address, and that equipment details may be submitted individually or in bulk, with bulk spreadsheet uploads recommended for larger numbers of items, alongside details of where to obtain assistance.
