If you don't follow an improvement notice, you're breaking the law. This is called an unlawful act. However, if the improvement notice includes suggestions or recommendations, you don't have to follow these. Not following recommendations isn't against the law.

Remember, an improvement notice is an official document that tells you to fix something. It's important to do what the notice says you must do. But if it just suggests something, you can choose whether to do it or not.
