Do you need planning permission to install a smaller pool?
Not necessarily. You usually don’t have to, especially if there is no change of use required in the land, but the rules can be fairly complex. We would recommend contacting your local council to double check. There are many different rules and regulations so it’s important to make doubly sure before you get started with your installation. But, if you are building a swimming pool inside of a new extension, you will need to have already gained planning permission for that extension in the first place. You don’t always need it if you’re only building a sliding door cover though.
