10th percentile. Not automatic, it's up to you to report it.
When ordering GEA-FTTC, you may cancel within 90 calendar days of installation if the line speed degrades to the point of being significantly lower than the speed estimate provided at the point of sale and, having raised a request for investigation, we are unable to resolve the issue.
In this case, you can request reimbursement for the connection, rental and cease charges and you won’t have to pay any early termination charges. We will not reimburse any event charges you may have incurred as part of the provision or investigation process. This is the 90 day rule as in section 4.
We define “significantly lower” as not meeting the 10th percentile speed for lines with the same line characteristics (dB loss when calculated at 300kHz) when the line is operating on the Dynamic Line Management (DLM) “Speed” policy. The 10th percentile speeds for each line are published on the Range of Values file on the BT Wholesale.com website.
