Wholesale Line Rental 3 (WLR3) Premium
With WLR3 you can offer your own-brand phone service on our network. We provide, maintain and repair the lines so you can focus on giving your customers high-quality services.
WLR Premium adds lots of extra features – like fast, prioritised repair times, call divert capabilities, service management centre support, access to tighter appointment slots and named engineer services.
How it works
Using WLR3 means you agree to Ofcom’s general conditions of entitlement.
BT is closing the public switched telephone network (PSTN) that supports several of our products including WLR3 analogue by the end of 2025: see details and key dates.

You can find out more about Business 2 Plus and more focused appointments in the Service Products section of our price list. Go to Repair service levels and Flexible and more focused appointments.
To use our named engineer service you’ll need to be set up by our customer establishment team to order Service Based Solutions (SBS) modules. Once you order, we’ll send the information from the service order and the SBS order to the Openreach control team. They’ll then find two available engineers with the right skills. The first is who we plan to send. The second will be on standby in case there’s an issue on the day and we need to send them instead.
Ordering lines for events and exhibitions
We deliver and maintain temporary fixed lines for events and exhibitions up to the last fixed network termination point. We also offer onward extension wiring to where those lines are going to be used – for example to hospitality tents, exhibition stands or press boxes. Find out more in our events and exhibitions brochure.

Information on what happens when you order a product or raise a fault with us. You’ll also find links to documents like product descriptions, pricing information and contracts.
The following documents explain the functional changes and upgrades we’ve made with each release, and how they affect the way our system interacts with yours.
They’re for your technical teams who design and build interfaces into the Openreach B2B gateway.
When we’re going to make a change, we’ll create a new document which we’ll publish before testing or release. We’ll then update this if we need to, based on our findings. So keep checking back for updates.
(We reserve the right to change functionality as part of a release, and to add a new document to reflect this.)
You can now find Functional Specification, and B2B/XML Release Documentation on iPublish, which can be found within the 'Your tools' section on your Dashboard.
Design specs for your technical teams who are designing and building B2B interfaces into the Openreach gateway. You can find B2B baseline documents and EMP response codes by logging in to your Openreach account.
