Federal politicians, judges and agency heads will get a two per cent bump in pay from next week.

The Remuneration Tribunal on Thursday decided to grant the increase to public officer holders starting on July 1.

It follows a two per cent pay rise in January last year, and 2.4 per cent boost in 2013.

"The tribunal considers it important that remuneration for offices in its jurisdiction be maintained at appropriate levels over the longer term to attract and retain people of the calibre required for these important high level offices," it said in a statement.

The tribunal received a "notable increase" in submissions asking for more money for offices and individual office holders based, in part, on pay in the private sector.
