If you live in a flat, you’ll definitely need to apply for planning permission. If you’re in a house, it may not be needed if you already have some sort of space in your basement, as the work should fall within permitted development.

However, if your house is on a flood plain or at risk of flooding, it’s likely you’ll be refused planning permission. You’ll have to get Building Regulations Approval, and if your home is listed, you’ll need Listed Building Consent. For more information of what is required, visit www.planningportal.gov.uk.
