GEN072/20 SML4 price increase

22/09/2020    For Information

This briefing is for all Communications Providers (CPs).

This briefing is to inform CPs about a price increase on Service Maintenance Level 4 (SML4) across all WLR, LLU and NGA products.

Openreach would like to notify CPs of an increase to Service Maintenance Level 4 (SML4) pricing across WLR, LLU and NGA products effective 1 January 2021.

This price increase is being implemented with a 90-day notification following discussion with Industry at the Copper & Fibre Products Commercial Group (CFPCG) in July and August 2020.

As communicated to CPs at the CFPCG, this will be the first of two increases to SML4 prices, with the second being implemented in April 2021. A 90-day notification will also precede the implementation of the second price increase.
