§ Mr. McCartney
Individual pension forecasts are produced by the Retirement Pension Forecasting System. It uses information from an individual's national insurance record held on the Inland Revenue's National Insurance Recording System (NIRS). It also uses detailed information supplied by the individual on form BR19 when they apply for a forecast.
The letter entitled "About your Retirement Pension" is produced by the Pension Computer System. It also uses information from an individual's national insurance record. The data are downloaded from the NIRS system to the Pension Computer System approximately four months and eight days prior to the customer attaining pension age to enable the notification to be sent and to allow time for a benefit application to be submitted and processed.
