Henry Duncan House


Taking its name from the founder of the world’s first commercial savings bank, Henry Duncan House is home to the Edinburgh office of TSB Bank.

The Problem

Having observed positive results and benefi­ts since 2010 with an installed base of over 20 powerPerfector Voltage Power Optimisation units across the TSB estate, Henry Duncan House became the latest addition to the power perfected TSB sites.

Our Solution

In order to meet the company’s commitment to reducing carbon emissions whilst ensuring a smooth electrical supply to the busy offices, the installation of a powerPerfector Plus proved ideal. The technology features dynamic voltage optimisation in addition to the power conditioning attributes of the voltage optimiser. The powerPerfector Plus responds automatically to changing voltage conditions to output an optimised voltage within a ­fixed band.

A consistent and reliable electrical supply is vital for TSB to enable 24/7 operations at Henry Duncan House, the powerPerfector Plus is proven to reduce the chance of system downtime.

The Results

For Mechanical and Electrical contractor, John G Mackintosh, Henry Duncan House was their second powerPerfector unit installation. Facilities Management Company, Mitie, worked alongside powerPerfector and John G Mackintosh to ensure a smooth project delivery from pre to post install.

This collaboration resulted in a quick and successful installation, with TSB able to swiftly resume operations.
