The draft scope covers Electrical and Plant (E&P) minor, planned, reactive and emergency works, including traction and non-traction power distribution, points and conductor rail heating, low-voltage systems, lighting and domestic electrical systems. It also covers Signalling Power Supply (SPS) minor works and renewals, including cables, cable routes, functional supply points, monitoring systems, schematic modifications, sub-fusing, network splitting and Distribution Interface Transformer Assemblies. Overhead Line Equipment (OLE) support includes isolation teams, nominated persons, Engineering Supervisors, Points Operators, Barrier Persons and DET Communications support. Work is expected across the Southern Region rail network, supporting planned programmes and emergent operational requirements. This procurement is at the planning and preliminary market engagement stage; it is not an invitation to tender. Network Rail expects to establish one framework lot using a framework agreement, with a planned contract period from 1 October 2027 to 1 October 2035. The stated estimated value is £28 million excluding VAT, or £33.6 million including VAT. The buyer expects the next notice to be published on 9 November 2026. Suppliers are invited to provide feedback through a market engagement survey, with responses expected by 12 noon BST on 3 September 2026. Feedback may influence the scope, framework design, lotting structure, duration, evaluation methodology and delivery requirements. The published scope and procurement strategy remain subject to change, and engagement participation will not form part of any future evaluation. The proposed framework should suit businesses able to deliver rail infrastructure maintenance, renewals, minor works and reactive responses across electrical power and overhead line environments. Relevant capability includes work on traction and non-traction distribution, low-voltage and lighting systems, points and conductor rail heating, SPS cables and equipment, power supply modifications, fault monitoring and network splitting. Specialist OLE resources are also relevant, particularly isolation teams, nominated persons, Engineering Supervisors, Points Operators, Barrier Persons and DET Communications support. Suppliers should be able to support planned, unplanned, emergency and operational requirements, with suitable labour, plant and technical competence. The buyer has indicated that SMEs and voluntary, community or social enterprises may be suitable for the planned lot. Market participants can help shape the future requirements through the engagement exercise. ## Notice Network Rail intends to establish a framework for the delivery of Electrical & Plant (E&P) Minor and Reactive Works, Signalling Power Supply (SPS) Minor Works and Renewals, and Overhead Line Equipment (OLE) Maintenance support services across the Southern Region.
