Requiring site lines


If you require construction site office phone lines you’ll need to order these through your communications provider as soon as possible.  Your communications provider needs to order a ‘short duration line for a site office’.  This is a specific product that will make sure your order follows the right process.

Your communications provider will also ask you for a contact name and number.  We want to make sure the right people are talking to each other, so this number should be for someone with the authority to make decisions on the supply of site services when speaking with our survey and planning teams.

Service Distribution Points

When you first meet, our New Sites representative will talk to you about installing a Service Distribution Point (SDP).

An SDP is a cabinet you install and own which we can install our Openreach network terminating equipment in.  They need to be robust enough to protect our equipment and weatherproof, and to keep a demarcation between our service and all electrical supplies.

It’s your choice if you wish to go ahead, but installing an SDP before site offices are in place can really help improve your experience.  It’s much easier for our engineers, giving them a central point making it quickly to provide new services and easier to test and diagnose faults.  It also ensures service stays intact even if your site office needs to move as the build progresses. 

You can find out more information about SDPs and required specification in the below document, or contact your New Sites Rep to talk it through.
