Why no open competition
Single Suppliers Technical Reasons
Published justification

The Chinook Delivery Team, part of the Ministry of Defence, intends to award a contract to Summit Defence Ltd for the supply and support of the High Pressure Aircrew Supply Oxygen System (HPASOS) used onboard the Chinook aircraft. The contract will be for a period of 12 months and have an estimated value of up to £220,000 (inc. VAT).

It is considered that this contract can be awarded under section 41 of the Procurement Act 2023 because the direct award justification specified in paragraph 6 of Schedule 5 (single supplier - technical grounds) applies.

This is because Summit Defence Limited is the Original Equipment Manufacturer (OEM) and Design Authority (DA) for the HPASOS and has supported it since it was introduced into service on 1st March 2021.

Only the OEM has access to the technical knowledge and documentation to meet MoD’s safety standards to fulfil this requirement, there are no reasonable alternatives.
