Question to the Home Office:

To ask the Secretary of State for the Home Department, what her Department's original budget for the Emergency Services Network programme was; how much her Department has spent since that programme started; and what the estimated final cost is in (a) real and (b) current terms.

In July 2021 the Emergency Services Network (ESN) Full Business case was approved by HM Treasury with a whole life cost of £11.3bn through to 2036/37.

In October 2024, HM Treasury approved an updated version of the business case which reflected a change in planning assumptions and timescales through to 2043/44 with a revised whole life cost of £19.2bn.

For the period 2015/16 to 31 March 2024, ESN has spent £5.5bn.

The estimated future cost to be spent by 2043/44 is £9.5bn (real), or £13.7bn (current).

In December 2024, the Home Office procured a new supplier for mobile radio and data services and intends to release a revised Full Business Case in Autumn 2025, which will set out a new timetable and costs, taking into account the impact of the recent procurement activity and the Competition and Markets Authority (CMA) Charge Control.

The Home Office’s priority is to deliver ESN as swiftly as possible and Airwave will be shut down only when it is safe to do so.

The Programme is under regular review by the IPA, NAO and engages regularly with PAC and HASC.
