Satellite insurance is the speciality property and liability cover written for the operational in-orbit life of communications, Earth-observation, navigation and scientific satellites, complementing launch insurance and providing the compulsory third-party liability layer required under the United Kingdom’s space-licensing regime.
Satellite in-orbit insurance is a small but volatile sub-market. Aggregate annual premiums have historically been in the order of USD 500 million globally, supporting insured values of USD 25 billion or more. Capacity has tightened materially following partial losses on Viasat-3, OneWeb and other anomalies in 2022 and 2023. The class is concentrated at Lloyd’s of London and a small number of European reinsurers.
Definition
Satellite insurance covers:
In-orbit total loss and partial loss including loss of transponders, power generation, propulsion margin or operational life.
Re-entry physical damage and de-orbit liability.
Third-party liability (TPL) for damage to other spacecraft, debris generation and ground damage on re-entry.
Loss of revenue in limited cases for failed transponders.
Hosted payload cover for piggyback instruments.
It is distinct from space insurance “launch” cover but is typically placed in the same Lloyd’s slip market.
Legal and regulatory basis
The UK statutory framework comprises:
Outer Space Act 1986 — UK persons operating satellites outside the UK.
Space Industry Act 2018 — UK-based launch and orbital operations.
Space Industry Regulations 2021 (SI 2021/792) — operating licence conditions including third-party liability insurance.
UN Liability Convention 1972 — strict liability for damage on the surface, fault-based liability in orbit between satellites.
IADC Space Debris Mitigation Guidelines — 25-year post-mission disposal benchmark for LEO objects, under review towards a five-year limit.
CAA “Risk Modelling and Insurance Statement” — sets the Modelled Insurance Amount (MIA) for UK licensees.
FCA Handbook ICOBS — distribution standards (see ICOBS).
How it works in practice
Satellite in-orbit insurance is generally placed:
Lloyd’s space slip with a lead syndicate and broad subscription (often 20–30 markets).
Annual renewals following acceptance of an in-orbit testing certificate from the launch slip.
Engineering survey — pre-renewal review of telemetry, battery state of health, propulsion remaining and component anomalies.
Partial loss formulae — pre-agreed percentage-of-sum-insured tables tied to specific component or capability failures.
TPL programme sized to the CAA-determined MIA and renewed in step.
Recent constellation losses have prompted shorter policy periods, tighter exclusions for collision in LEO and explicit debris-strike exclusions in some wordings.
Common variations and subsequent developments
Constellation portfolio wordings — risk-pooled across a fleet of small satellites with annual aggregate loss limits.
Active debris removal (ADR) — emerging cover for ADR operators (UK Space Agency funding for ClearSpace and other ADR missions).
Rendezvous and proximity operations (RPO) liability — collision and contact-loss risk during servicing missions.
Cyber cover — uplink command interception and TT&C protection.
Example
A geostationary communications satellite is insured for USD 200 million in-orbit value with a fleet of European underwriters led by a Lloyd’s syndicate. In year five a power-system failure renders one of 36 transponders permanently inoperative; the partial-loss formula in the wording pays 1/36 of the sum insured, USD 5.56 million, less the policy excess. The TPL layer (EUR 60 million matching the CAA MIA under the Space Industry Act 2018 licence) is unaffected.
