The Single Source Contract (Amendment) Regulations 2024 (SI 2024/420) relate to the pricing of single source defence contracts. These regulations require suppliers to demonstrate that their costs are appropriate, attributable, and reasonable, and they define the level of profit that can be applied. They are part of a regulatory framework established by Part 2 of the Defence Reform Act 2014 for contracts not subject to competitive tendering processes. The regulations come into force on 1st April 2024 and extend to England, Wales, Scotland, and Northern Ireland.
