The speed that’s being measured when we talk about broadband is ‘how fast is data being transferred’ and that is measured in megabits per second.
How fast you need depends on how your household will use the internet.
Things like high-definition video streaming, video calls and gaming all require much higher speeds. Suppliers offer a variety of tariffs to ensure there is one that meets the needs of your household.
To save costs you should only sign-up for a speed you will actually make full use of.
