ADS are once again holding a Defence Commercial Workshop training session due to popular demand.

Single source defence contracts for the UK are now regulated by law within a Single Source Procurement Framework established by Part 2 of the Defence Reform Act 2014. The law governs how contracts are costed, what profit is allowed, how pricing mechanisms work and gives MOD significant open book access to the contractor’s data. There are penalties for non-compliance. It is possible for contract prices to be re-set up to two years after contract completion. Understanding the rules is therefore vital to ensure a price is valid and will withstand scrutiny.

  • Opportunity to understand the latest regulations and statutory guidance.
