Ordering supplies to build our network

We’ll supply all the Openreach materials you need to build and install the network on your site, for free. Your Openreach field-based coordinator will work with your construction workforce or site manager to make sure you get the right supplies delivered, when you need them. We’ll normally supply materials at the same pace as your build programme. But if your project is particularly large (and as long as you have secure storage facilities), we can also deliver materials in bulk. You’ll need to allow 10 days for us to do this.

Our materials are for your own use only

You should only use the materials we give you to connect homes on your development to the Openreach network. If you lose, damage or misuse any of our supplies, we’ll charge your company for the replacements.

To help you identify the right supplies, we’ve put together a guide and a list of supply codes.
