Summary of the contracting process

Ofgem has procured engineering asset auditing and inspection services for gas and electricity network sites across the United Kingdom. The work combines audits of licensees’ asset-management systems and procedures with on-site inspections of major electricity and gas infrastructure. Electricity assets include transformers, switchgear, protection systems, cables, overhead lines and associated civil structures; gas assets include terminals, pipelines, compressor stations, storage and pressure-control facilities, metering and safety systems. The supplier also reviews maintenance plans, records and performance data, assesses whether assets are maintained to relevant standards, and investigates network incidents when required. Outputs include audit and inspection reports, incident reports and presentations to Ofgem, with recommendations where maintenance or governance needs improvement.

Ofgem awarded the single-lot contract to AtkinsRéalis UK Limited and RINA Consulting S.p.A. The award is pending, with an award date of 29 September 2026; the scheduled signature date is 9 October 2026. The contract period is 19 October 2026 to 18 October 2028, with options for two 12-month extensions to 18 October 2030. The awarded value is £3,333,333.33 excluding VAT (£4,000,000 including VAT). The procurement used an open procedure, with an accelerated timetable. Evaluation weighted technical quality at 60% and commercial price at 40%. The lot was identified as suitable for SMEs, and suppliers were assessed against economic and technical selection criteria.

This award shows demand for specialist engineering assurance across regulated gas and electricity networks, combining asset-management audits, site inspections and technical incident investigations. Credible competitors would need engineers and inspectors able to assess diverse high-voltage electrical and gas infrastructure, interpret maintenance schedules and records, and judge asset-management governance against relevant standards and international best practice. They would also need the capacity to conduct site visits across the United Kingdom, review licensee performance data, investigate incidents and produce clear evidence-based reports and presentations for a regulator. Practical experience identifying maintenance deficiencies and recommending improvements is central to the requirement. The work spans both network sectors and a wide range of equipment, so suppliers would need breadth of technical expertise or a delivery team able to cover the disciplines reliably. The contract was awarded to two large suppliers, while the lot was considered suitable for SMEs.
