Will I need building control?
It depends on the project but for most major construction projects in your home, such as extensions and conversions, you'll need to make a building regs application so that your local building control team can visit the site and check that your work is compliant.
Take a look at our getting started page for some handy links and resources, or visit our quick list page which tells you all the construction projects which need building control.
We also have a page on building control exemptions.
