Defence Estates has used a prime contracting system since 2001

This divides the UK into five regions, each run by a single contractor with the job of organising between £400m and £750m of work over a seven-year period. Alongside this is a £700m project to build the Defence Technical College in St Athan in the Vale of Glamorgan and the multibillion-pound SLAM programme for the renovation of forces housing, much of which is procured using the PFI. The Next Generation Estates Contracts frameworks will be used for everything up to £20m. Above that, alternatives will be considered and anything worth more than £50m will go out to competitive tender.
