Energy services provide you with water, electricity and gas. They are also known as essential services, as problems with them can seriously affect you.
Energy providers promote their services and products in a number of ways, including TV, radio and newspaper ads, and through door-to-door selling and telemarketing.
You have rights when choosing or changing energy providers. For more information, view our Tips for buying energy products and services page.
