First: What Can
We Map?
• PAC Report Summary
– BT is preventing local authorities from providing
proper information on the areas it will and will not
cover with superfast broadband. (page 3)
– Details about speed and coverage are treated as
commercially confidential in each local project.
– BT …has no objection to publishing this data for
finalised contracts.

What Should We
Map?
• We know the targeted Cabinets
• The SCT limits the Postcodes upgraded
• The Physics limits the distance
• Publicly available – BT’s best guess of
– Address to Cabinet mapping
– Products and speeds
• And the BT API Access is available on request

Here’s a cabinet serving only 18 premises in the intervention Area!
How many disappointed people if we just highlight the postcodes?
Highlighted rows are served by multiple cabinets: 1,2,3 and 25
How effective is a threshold?
Must be premise based to communicate effectively
Overspill can be avoided by “good choice” of Postcodes to include but this leaves some people without coverage.
In this example, there are 18 in one block so surely this must be simple for the alternative provider to fix – but they did not declare it as covered in the OMR so it must be State Aid White.
The premise checker confirms this, two sides of the same street. In the OMR we gave them an opportunity to undertake to cover these but were unwilling to commit.
The premise checker says it all
Some areas have small gape across multiple cabinets, e.g. 35 Premises
