What it means for you
The line and network you use do not change.
Under Onestream, prices rise £2.75 a month every April. Check what your contract says.
Neither Cuckoo nor Onestream lists a social tariff. Providers such as BT, Virgin Media and Hyperoptic offer one.
If your terms change in a way that is not to your benefit, Ofcom rules let you leave without an exit fee. One Touch Switch means you only contact your new provider.
