Through this Preliminary Market Engagement Notice (PMEN), the Ministry of Defence seeks expressions of interest from suitably qualified suppliers. Any interested supplier with the experience, capability and capacity to deliver this service are asked to register their interest by contacting the buyer at the details provided in this notice. In your expression of interest, please indicate your preferred duration of any potential future contract.
This PMEN has been published for the purposes of Market Sounding and to assist in the determination of the procurement strategy. No formal procurement has been launched. This is not a commitment by the UK Ministry of Defence to place a contract or launch a tender in the future.

The Project Team will provide information and guidance on the processes and requirements to obtain the necessary approvals, to support fair and open competition and to minimise barriers to entry.
