Many kinds of buildings and structures can be built in your garden or on the land around your house without the need to apply for planning permission.
There are, however, limits and conditions which must be followed, and in some circumstances, you will need to apply for planning permission.
Building regulations will apply if your installation involves carrying out electrical or gas works in your home or garden. You should take care that the installation is safe.
You may wish to use an installer who is registered with a competent person scheme or seek approval from a building control body. If you are unsure about whether you are required to comply, you may wish to contact your local building control body.
