About Imperial College

Healthcare NHS Trust is one of the largest NHS trusts in England, serving hundreds of thousands of patients annually and managing substantial administrative correspondence.

Reducing Mail Costs at Scale

The Trust was seeking ways to reduce the cost of handling its outgoing mail, which totalled around 500,000 unsorted second-class mail items annually. With budgets under pressure, identifying sustainable cost savings became a key priority.

Whistl’s Mail Management Solution

Whistl partnered with the Trust to provide a full mail service solution. This included:

• Daily collection and processing of all outgoing unsorted mail
• Migration of volume to Whistl’s Economy service for improved cost efficiency
• Regular service reviews and optimisation support

Data-Driven Mail Management

To ensure ongoing visibility and control, Whistl implemented:

• Monthly detailed data reports to help track postage expenditure
• Regular account management meetings to review usage trends
• Proactively identify new cost-saving opportunities

By switching to Whistl’s mail service, the Trust is now projected to save over £15,000 per year on postage costs -without compromising reliability.
