How is BT Full Fibre broadband installed?

Getting Full Fibre gives you faster, more reliable broadband. Depending on your address, you may be able to set it up yourself, or you may need an engineer to complete the installation.

We'll let you know which option applies when you place your order.

Before your installation

When you order Full Fibre, you'll choose a date that works for you.

Before your broadband goes live:

  • we'll send you a BT Smart Hub if you need one
  • if you're already using a compatible hub, we'll let you know if you can keep using it
  • make sure you've collected your hub if you missed the delivery
  • think about where you'd like to place your hub for the best Wi‑Fi coverage

You may also see engineers working near your home before your go-live date. They're preparing the network, so you don't need to do anything.

If you can set up Full Fibre yourself

We'll send you everything you need.

Once your service is ready, simply connect your Smart Hub using the instructions provided and follow the steps to get online.

If an engineer is needed

Some installations need an engineer to complete the work.

We'll let you know if this applies to your order and help you book an appointment.

Did we originally say an engineer wasn't needed?

When you first placed your order, we may have told you that you could set up Full Fibre yourself.

Sometimes, after additional checks, an engineer visit is needed to complete the installation.

The engineer may need access to both the inside and outside of your property. Your broadband will go live once they've finished the installation and tested the connection.

Why has this happened?

This could happen because:

  • Openreach do a line test after the order is placed. They may notice something isn't quite right and this means an engineer needs to visit your property
  • Openreach have asked if there's a problem with the Openreach equipment in your house, and you've replied to say that there is
  • you've told us that you have a telecare device after the order was placed

What happens on installation day?

Your engineer will call ahead to let you know when they're on the way. Let them know about any access restrictions.

Installation usually takes up to 3 hours and involves work inside and outside your home.

Someone aged 18 or over must be available for the whole appointment to provide access and agree where the equipment should be installed.

How is Full Fibre installed?

  1. You'll agree with the engineer where the fibre connection will enter your home.
  2. The engineer will drill a small hole through an external wall to bring the fibre cable inside.
  3. They'll install an external junction and run a fibre cable from the local network, either from a telegraph pole or underground ducting.
  4. Inside your home, they'll install an Openreach ONT (Optical Network Terminal), which connects to your Smart Hub.

Good to know

If your connection is delivered from a telegraph pole, the engineer may need to drill up to two additional holes to safely secure their ladder.

Getting connected

Once the installation is complete, the engineer will connect your Smart Hub to the Openreach ONT. They'll test your connection to make sure everything is working properly.

You can manage your broadband using the My BT app.
