Full fibre

Full fibre. All the way to your door.

Glass, not copper. Your own line, not the street's. Speeds up to 900Mbps.

So what actually is it?

Full fibre is a fibre optic cable that runs from the exchange straight into your home. The industry calls it FTTP — fibre to the premises. We just call it full fibre, because it is fibre the whole way.

Most homes in the UK still have something older. Either FTTC, where fibre reaches the green cabinet on your street and copper does the last stretch to your house. Or ADSL, which is copper the whole way.

That last bit of copper is where the trouble starts. It is slow, it does not love British weather, and you are sharing it with up to 74 other homes.

Copper vs glass

Same broadband bill. Very different cable.

The old way

  • Copper for the last stretch to your house
  • 80Mbps at the very best, and only if you live near the cabinet
  • Shared with the street, so it sags at peak times
  • Copper lasts about 5 years before it starts playing up

Full fibre

  • Fibre optic all the way to your front door
  • Speeds up to 900Mbps, wherever you live on the street
  • Your own dedicated line — nobody else on it
  • Glass lasts decades, and shrugs off the weather

What you'll actually notice

It's properly fast

A box set downloads in a minute and a half. On copper, the same download takes the best part of 20 minutes.

No more green cabinet

Your line does not stop at the box on the corner, so it does not matter how far down the road you live.

Harder to meddle with

Light down a glass thread is a nuisance to intercept. Copper is rather more obliging.

Ready for what's next

Copper is being switched off across the UK. Fibre is the thing replacing it, so this is the last upgrade you need.

How it gets installed

If your home already has full fibre, there is nothing to install — we post you a Hub and you plug it in.

If it does not, an engineer needs to bring the fibre in. Budget about 3 hours.

Renting? The engineer drills a small hole for the ONT, so have a quick word with your landlord first.

  1. You pick the day

    Choose a date and a time slot when you sign up. No sitting in for a mystery visit.

  2. The engineer plots a route

    The fibre comes in either overhead from a telegraph pole, or underground.

  3. A small box goes on the wall

    One outside, about the size of a tablet. One inside — your ONT — where the fibre lands.

  4. They test it, then tidy up

    They check you are getting the speed you should be, and leave the place as they found it.

  5. You plug in your Hub

    About 5 minutes. Then you are online.

Questions about full fibre

Do I still need a landline?

No. Full fibre does not use the old phone line at all, so there is no line rental hiding in your bill.

What speeds can I get?

Up to 900Mbps, and the speed you pick is the speed you get — it does not drop off because you live at the far end of the street.

Which speed you need depends on how many of you there are and what you are all doing. Most homes are grand on the middle one.

Is upload speed different to download?

On copper, uploads are a fraction of downloads. On full fibre they are much closer together, which is why video calls and big file uploads stop being a chore.

What happens to my current connection?

Copper is being retired across the UK. Your current connection will be switched off at some point — the date depends on your address. Moving to full fibre now saves you doing it in a hurry later.

Is it more expensive?

Usually not by much, and often not at all. People tend to be surprised by how close full fibre is to what they were already paying for something a lot slower.

Can I get it where I live?

Pop your postcode in and we will tell you in a few seconds. Full fibre is still rolling out, so if it is not at your address yet, it is worth checking back.
