In most places, you report once a year. But for big sellers of electronics and batteries, it's every quarter. Reporting times depend on your license and usually last from January 1 to August 1, depending on the country.
For example, in the UK, if you make packaging, you must send your yearly EPR report by May 31 the next year. In France, if you make batteries, you need to send your EPR reports every quarter by the 15th day after the quarter ends.
Lovat users don't need to worry about deadlines. They can check their EPR deadline in the Lovat dashboard and get reminders.
Prices for yearly reports start at 190 euros (without tax) for packaging and 250 euros for other types.
