The commission has been weighing up evidence from stakeholders about the agreement's effectiveness and is expected to make the plea this week.
It is also expected to call for updates to the Compact itself. Helen Baker, the interim Commissioner for the Compact, said: "We will be discussing with all our partners how best to evaluate and update the Compact and codes to keep them relevant for the future."
The news comes as Compact Week draws to a close today. The week's activities included an event in which organisations and Ken Livingstone, the Mayor of London, restated their support for the London Compact.
Local authority umbrella body London Councils and the Government Office for London signed the agreement for the first time.
