Electricity and gas regulator Ofgem has reappointed all 11 firms on its E-Serve panel after exercising an option to extend its legal services framework for a further two years.

Ofgem's E-Serve division focuses on delivering the government's consumer and environmental schemes, as well as renewables and energy efficiency to help meet the government's decarbonisation targets.

The eleven firm panel, which is made up of Addleshaw Goddard, Bevan Brittan, Bond Dickinson, Burges Salmon, Hogan Lovells, Maclay Murray & Spens, Nabarro, Pinsent Masons, Sharpe Pritchard, Simmons & Simmons and Dentons, was first established under Ofgem's E-serve Legal Services Framework Agreement in October 2012 for a period of two years.

Based on the performance of the panel, the regulator has decided to exercise an option to extend the framework until 2016 as opposed to replacing it with another structure. When that arrangement expires, Ofgem will need to run another procurement process for its legal services.

Catherine Scott, E-Serve legal director, now manages the framework and procurement process after moving from the Department for Transport in 2013.

The panel provides legal services on a 'call-off basis' where a 'mini-tender' process decides work between the 11 firms based on value for money and particular specialism.

In a statement, a spokesperson for Ofgem said: "We regularly review the quality of the service provided by firms under the framework and we ensure value for money by running call-offs under the framework where appropriate. The framework is flexible and gives us access to appropriate expertise at competitive prices.'
