What does the 2026 UK/EU Treaty in relation to Gibraltar mean by aggregation of insurance periods for pensions?
Short answer
The 2026 UK/EU Treaty in relation to Gibraltar requires Spain and Gibraltar to recognise insurance, employment, or self-employment periods completed under each other’s legislation. This means a frontier worker’s contributions in both jurisdictions can be combined to qualify for a pension, rather than relying solely on one system’s minimum contribution rules.
Detailed answer
Article SSC.7 provides that each competent institution must take account of periods completed under the other’s legislation as though they were completed under its own. This prevents contribution gaps from disqualifying workers who have split careers between Spain and Gibraltar. Aggregation does not merge the systems, but it ensures eligibility is assessed on a combined record, with each jurisdiction later calculating and paying its own share under the pro rata mechanism.
