Frequently asked questions

We have two types of broadband: superfast fibre BT Infinity and standard BT Broadband.

BT Infinity gives you a superfast fibre optic broadband connection with speeds of up to 76Mb which lets you do more online, with everyone online together. It's great for downloading or streaming movies, TV shows and music. You can watch iPlayer with less interruption and HD video with less buffering.

If you can't get BT Infinity or if you live in a home with lighter internet usage and fewer devices, standard BT Broadband is ideal for you. It's perfect for everyday browsing, uploading and sharing photos and updates on your favourite sites and streaming content online.
