The Challenge: Business Continuity with Zero Margin for Error

At One and Two New Street Square, Deloitte’s primary UK headquarters, Test Inc. was tasked with delivering full electrical compliance in a live, high-security environment where power isolation was not permitted. Historic gaps in data, system access, and asset identification had made previous compliance efforts incomplete or impossible.

Separately, during a major refurbishment at Deloitte’s 66 Shoe Lane site, works were suspended when the principal contractor declared the building electrically unsafe. Construction halted. The site was evacuated. Deloitte required immediate investigation and verification from a trusted partner.

In both locations, continuity was essential.

In both cases, Test Inc. was called upon for its speed, precision, and advanced methodologies.

The Solution: Non-Disruptive Compliance and Emergency Diagnostics

At New Street Square, Test Inc. deployed its proprietary Optima24™ system — a non-disruptive testing solution designed to evaluate energised systems without shutdown or isolation. This enabled full compliance without interrupting Deloitte’s daily operations.

Previously unidentified risks were located and resolved. Critical faults, undetectable through conventional methods, were exposed and addressed. The result was complete compliance with uninterrupted uptime.

At 66 Shoe Lane, Test Inc. carried out a comprehensive electrical investigation of the primary earthing and bonding network. Leveraging deep expertise in large-scale, complex infrastructure, the team validated that the installation, though unconventional, met safety standards. The building was declared safe and construction works resumed promptly.

Building Confidence Through Execution

Deloitte’s decision to engage Test Inc. across its UK portfolio reflected confidence in the firm’s ability to deliver under pressure. What began as a response to technical obstacles evolved into an operational partnership — one based on trust, accuracy, and long-term assurance.

In both cases, Test Inc. provided more than a fix.

They delivered a standard of precision and professionalism that enabled one of the world’s most respected firms to continue operating without compromise.
