Published terms and linked processes

• Options are statedLot 1

  The original contract included an option to extend the contract by 2 years to 13 March 2026 and an increase in contract value by an additional £10 million. A contract amendment in February 2024 applied the advertised 2-year extension option and reduced the value of the contract from £27, 167,193 to £18,005,643. The reduction in budget was as a result of FCDO Business Panning adjustments. The scope and objectives remained the same but in line with the flexible and adaptive approach some activities were scaled back. This modification will extend the contract for a further two years from 13 March 2026 to 13 March 2028 but remain within the original contract value of £27,167,193
