UK6 - Contract Award Notice
Summary of the contracting process

The Oil and Pipelines Agency commissioned environmental investigation services at Oil Fuel Depot Thanckes. The work supports ongoing ground investigations, following findings in a 2023 monitoring report, with groundwater monitoring and investigation of contamination plumes where the Agency identified gaps in their delineation. The initial work is intended to assess and close those gaps and progress towards an agreed remediation strategy and programme. The work is at OFD Thanckes, in Cornwall.

The procurement is complete and the contract was awarded to Arthian Limited on 22 September 2026. This was a mini-tender under the Oil and Pipelines Agency’s existing PSF Lot 8 arrangement; the procurement was below the applicable threshold. The awarded value is £19,873.10 excluding VAT (£23,847.72 including VAT). The contract period runs from 1 October to 31 December 2026. The procurement was for one lot.

This award indicates demand from the Oil and Pipelines Agency for focused environmental investigation work at its Thanckes depot. Suppliers seeking to compete for comparable requirements should be able to undertake groundwater monitoring, investigate and delineate contamination plumes, identify evidence gaps and help develop remediation strategies and programmes. Experience supporting continuing ground investigations would be relevant to this particular requirement. The award was made through a mini-tender under the Agency’s PSF Lot 8 arrangement, so familiarity with competing through an established purchasing arrangement would also be pertinent. The awarded work is a defined investigation package rather than a broad environmental services contract.
