Most EU law will continue to apply until/unless it is specifically repealed. National laws that implement the EU law are usually required for each country to implement the law in accordance with its own legal codes and structures. The UK is still inside most of the treaties until next year, as there is currently a "transition period" in effect, but even when that ends, a lot of EU law will still be part of UK law.
