SLR recognised in the top 30 Expert Consulting Firms in the 2025 GAR Expert Witness Power Index

Each year, as part of the Global Arbitration Review‘s survey, the GAR Power Index ranks the most active specialist international arbitration consultants based on the size and number of disputes their experts have supported over the previous two years.

In 2025, SLR has been included in this widely recognised industry resource, reflecting its established role in providing expert witness and advisory services in arbitration and disputes within a broad range of sectors including: mining, oil & gas, power & renewables, and civil engineering.

For over 20 years, SLR has provided expert witnesses and advisory services, grounded in real-world industry experience. Our independent experts offer insights informed by our ongoing technical and commercial work across the energy and natural resources landscape. What sets SLR apart is our deep understanding of the operational realities behind industry decisions.

In arbitration settings, our experts reach beyond the language of the contract to articulate the practical, contextual drivers of industry decisions - explaining how situations have come to pass, not just how they ought to be.

Our full profile is featured in the 18th edition of the GAR annual survey. SLR’s entry in the top 30 of GAR’s Expert Witness Power Index is based on the activity of our Oil & Gas Advisory team only – next year’s submission will include data from across all SLR’s industry services.
