What pays for a garrison — and how stable it is

A defence-estate PPP houses and supports a garrison: an investor funds the barracks and facilities and is paid a long, government-backed, inflation-linked availability charge for the accommodation — paid whether or not every bed is filled — plus garrison services (messing, transport, training-area and FM) that flex with how many troops are actually on the base. The accommodation annuity is a rock-solid contracted core; the services layer adds a manning-linked kicker. The case turns on the size of the estate, the charge, and the manning level.

Why investors like defence-estate PPPs: the accommodation availability charge is a multi-decade, sovereign-backed, inflation-linked annuity with essentially no demand risk — the MoD pays for the bed-spaces regardless of manning — which supports very high leverage and low, stable equity returns. The garrison-services layer (catering, transport, training-area upkeep) flexes with how many troops are on base, adding a modest manning-linked kicker. The result is one of the lowest-volatility income streams in infrastructure.

Illustrative model. Represents an availability-based defence-estate / garrison-support PPP. Revenue = a contracted accommodation availability charge (bed-spaces × charge, paid regardless of manning) plus garrison services (messing, transport, training-area & FM) and training/estate income that scale with the manning level. Operating costs (estate FM & lifecycle, catering & garrison services, base staffing, insurance & admin) are part fixed (per bed-space) and part manning-driven — so the accommodation annuity is a stable high-margin core while services revenue and cost flex together. EBITDA = revenue − operating costs; excludes upfront construction capex and senior debt service. The investment case is a simplified DCF. For illustration only — not investment advice, and not any specific asset.
