Certain pension benefits are indexed each 1   January and 1   July.

For pensioners aged under 55, the indexation is based on positive movements in the consumer price index.

For pensioners aged 55 or older, movements in the consumer price index are relevant, but they are only part of the indexation method.

For all pensioners, there are rules dealing with special cases including pension benefits that have only recently become payable and situations involving commutation of a portion of a pension benefit.
