We engaged Grosvenor to deliver mobile patrol cover across our multi-site office portfolio and have been very impressed. Patrols are conducted to a structured schedule with GPS-verified check-ins, and we receive detailed incident logs every morning. The team identified a perimeter issue at one of our sites during an overnight patrol that could have been a significant liability  that kind of proactive approach is exactly what we need from a security provider. Reliable and highly professional.

Operations Director, Professional Services Group

Grosvenor manage the daily opening and securing of our office complex across multiple buildings and the service has been dependable throughout. Officers arrive ahead of schedule, carry out a thorough sweep before handing over to our facilities team, and ensure the premises are fully secured each evening. The service has reduced the operational pressure on our own staff considerably. Response time for ad hoc schedule changes could occasionally be a touch faster, but overall we are very satisfied with the provision.

Estate Manager, Corporate Property Group

We used Grosvenor to provide security personnel for a high-profile executive conference and the team were outstanding. Officers were smartly uniformed, discreet, and managed delegate access with precision. A sensitive situation involving an unauthorised individual was handled calmly and without disruption to the event — exactly the composure you need at that level. Several of our senior leadership team commented positively on the security presence. We will be using Grosvenor for all future corporate events.

PA to CEO, Investment Management Company

Grosvenor provide both our mobile patrol rounds and lock/unlock service across our business campus, and the integrated approach has worked extremely well. Having the same officers responsible for the full security operation means they have a thorough knowledge of the site and can identify anything out of the ordinary quickly. Communication with the management team is clear and professional. It is rare to find a security provider that delivers consistently at this level — we would not hesitate to recommend Grosvenor to other corporate occupiers.
