Choosing a provider in Dolgellau

Most addresses in Dolgellau can order from providers on the Openreach network. If Openreach has built full fibre to your street, all of them can sell it to you, so the choice comes down to price, the yearly price rise and customer service.

Virgin Media and independent full fibre networks only cover the streets they have built. If one of them covers you, it can be worth comparing, as they often sell faster speeds for similar money.
