Charge Controls for Local Loop Unbundling (LLU) and Wholesale Line Rental (WLR)

Communications providers which use BT’s copper network to provide wholesale and telephone and broadband services to homes and businesses are required to pay Openreach, BT’s wholesale access division, a fee to access the network for the provision of various wholesale telecoms services. The wholesale charge for such services is regulated by Ofcom where BT has been found to have significant market power in the delivery of these services. On 26 June 2014 Ofcom set charge controls for two such categories of services: local loop unbundling (LLU) and wholesale line rental (WLR) services.

Safeguard cap for Second Class stamps

Ofcom removed the significant majority of regulatory controls on Royal Mail’s prices as part of its review of the regulatory framework for the postal sector concluded in March 2012, However, to ensure that a basic universal postal service is available to all, Ofcom capped the prices that Royal Mail can charge for Second Class stamps up to 2kg. This cap is expected to be in place for the seven years of the current regulatory framework (i.e. till March 2019).

The cap on the Second Class Letter price was set at 55p in 2012, increasing by CPI from 2013 onwards. The cap for Large Letters and packets (up to 2kg) is a control on the maximum level of prices for the basket of products. This takes the form of a basket weighted by volume which allows Royal Mail flexibility to set the prices of the eight individual products within the basket. The level of the Large Letter and packet cap for 2012 was set at an increase of 53% on 2011-12 prices (consistent with the Letter increase), increasing by CPI from 2013 onwards.

Safeguard cap April 2012 April 2013 – March 2019
Letters 55p 55p + CPI
Large Letters and packets 2011-12 average price + 53% + CPI
