The government has renegotiated its bulk software licensing deal with Oracle to save the public sector £45m.
The original framework licensing agreement was signed three years ago by public sector procurement body the Office of Government Commerce (OGC).
The new three-year aggregated spending deal came into effect on 1 April.
It includes consultancy services and a reduction in the minimum number of users required for enterprise licensing agreements to kick in.
Hugh Barrett, chief executive officer of OGC trading arm OGCbuying.solutions, said, “This agreement is a good example of the use of the wider public sector's purchasing power to deliver benefits to the taxpayer.”
The OGC has similar bulk licensing deals with Microsoft and other major IT suppliers.
The Microsoft deal was also recently renegotiated to save the government more money.
