The UK government laid a departmental minute before Parliament on November 12, 2026, setting out the public financial exposure associated with lower satellite liability limits and waivers for selected space missions. The arrangements would allow qualifying operators to reduce their licensed liability from a default £50 million to £20 million or £0, depending on the evidence submitted.
The departmental minute implements part of the insurance and liability package announced alongside the UK Space Strategy in September. It identifies a maximum additional government exposure of £50 million for an individual claim when an operator receives a zero-liability limit or a qualifying mission waiver. The Treasury has approved the proposal in principle.
These arrangements concern orbital activities. Launch operations are covered by a separate notification. The distinction separates the financial responsibilities associated with operating a satellite from those attached to the vehicle that carries it into space.
How the Liability Tiers Work
The government’s financial tools package establishes two initial assessment criteria: security and access to space-sustainability information. Applicants may voluntarily submit supporting evidence through the Civil Aviation Authority for UK Space Agency assessment. Meeting one criterion gives a £20 million limit; meeting both gives a £0 limit.
The security criterion covers participation in agency-funded cyber and physical security assessments. The sustainability criterion concerns access to specified standards and current information. The package identifies ISO 24113, the BSI Flex 1969 space-sustainability framework, and information supplied through the Earth and Space Sustainability Initiative.
The detailed package applies the approach to new orbital-license applications submitted on or after December 1, 2026. Earlier applications will not be reassessed under this mechanism. The government also plans to express relevant new liability limits in pounds sterling, replacing euro-denominated limits.
Why Government Retains Exposure
International liability and a domestic operator’s license conditions perform different functions. The Liability Convention assigns responsibility to launching states for damage caused by space objects. A launching state includes a state that launches or procures a launch, as well as one whose territory or facility is used.
For damage on Earth’s surface or to aircraft in flight, the convention establishes absolute liability. A claimant does not have to demonstrate fault in the same way as under the convention’s provisions for damage to another state’s space object away from Earth’s surface. Those provisions use a fault-based standard.
Domestic licensing determines how an operator reimburses government for claims within the applicable legal framework. A lower operator limit changes that allocation of financial responsibility. Government remains responsible for meeting its international obligations, including amounts above the operator’s applicable limit.
The UK’s annual accounts explain the existing arrangement under the Outer Space Act 1986 and Space Industry Act 2018. Standard satellite missions have generally carried a €60 million limit, with higher limits possible for higher-risk missions and third-party insurance required to the licensed amount. Third-party cover concerns damage to others, rather than replacement of the operator’s own spacecraft.
Waivers for Servicing and Lunar Missions
The new package also sets a zero operator-liability limit for qualifying in-orbit servicing, assembly and manufacturing missions, and for lunar missions. It applies to relevant licenses issued from December 1 for missions planned to launch before the end of 2030. The detailed policy covers the licensed activity’s duration, including transit to client spacecraft and, where applicable, reentry.
Servicing missions perform work on another spacecraft after launch. Assembly joins components in space, and manufacturing produces materials or products there. The waiver places these activities within a defined licensing treatment alongside lunar operations.
The minute estimates an actuarial expected government cost of approximately £700,000 annually for the measures, with an additional £900,000 annually for a large-constellation application under the variable-limit approach. These figures represent modeled exposure across possible outcomes. The government expects no payment in nearly every year because it assesses claims as remote.
Parliament has a 14-sitting-day period in which an objection can trigger further examination before final approval to incur the liability. The government has identified late 2027 or early 2028 for consideration of the next iteration of the variable-limit approach.
