Sometimes translated acts can be found on the websites of Dutch governmental organizations or ministries. For example the regulations on the website of the Authority for Consumers and Markets.

Try to find translations with a search engine: use the English translation of the name of the act or the Dutch name (title) in combination with ‘English translation’ or ‘translated’ e.g. “environmental act” AND (translation OR translated) AND English.
