Site access management
Ensuring our estate is managed efficiently and securely is always a priority. Innovation is one of our core values and we constantly look for improvement in all that we do. In partnership with Locken, Cornerstone has a digital mobile application which is used to activate a Locken key to access all of our sites.
- Super secure access – all visits will be logged through the digital system for activities such as Health and Safety or site maintenance
- Real time reporting and tracking of who has visited our sites
- The ability to remove redundant, lost and stolen keys from our estate, enhancing security.
The key update is that a Notification of Works (NoW) booking is mandatory for all site access, regardless of whether a Locken key is in use.
We strongly recommend all visitors accessing Cornerstone sites, including contractors, suppliers, and managed service providers, familiarise themselves with the process.
We have outlined the key details within our Locken Lockdown Guide in the accordion section below, helping you understand what’s changing and how it affects you. Please review each section carefully to ensure you comply with the new process and avoid disruptions to site access.
Locken Lockdown: What you need to know.
It is now mandatory for all Cornerstone site visit access to have a Notification of Works (NoW) booking to allow entry, irrespective of Locken status. Please explore each accordion section to understand what this means and what you must do.
For more Locken guidance and resources, including registering for the app or for more information on how to raise a request, please explore our resources on this page.
What is changing?
As we enhance how we manage access across Cornerstone sites, it is mandatory that all site access needs a Notification of Works (NoW) booking to allow entry.
What sites require a NoW?
All visits to Cornerstone sites, irrespective of Locken status, must have a valid booking.
How far in advance should I raise a booking?
You must raise bookings in parallel with checking and adhering to the site-specific access information requirements.
You can make future NoW bookings, and we will provide you with the latest information when booking the site visit.
How late can access be booked?
You can book access with a start time of 15-minute intervals, so if you need to book on short notice, the worst-case scenario is a 15-minute wait time before you can book on the site.
Do I need to give a specific time for my visit?
Where you intend to visit the site but are unsure of the exact time, you may book access for the whole day, i.e. 09:00-17:00. You can access the site as often as you need within these times. When finished, log that you are off-site and close the NoW.
How many days can I book access for?
You can only book access for the specific dates needed, but you can book a maximum of 5 days for more extended activities.
Please note
- You must ensure you book access following the access information in Siterra and mirror it in the Locken app.
- You must always adhere to notice periods and processes.
- If you manage suppliers who attend sites, please ensure they are aware of these changes.
- We strongly recommend that all visitors immediately start raising a NoW for access requests to become familiar with the process.
- Our customers – further peace of mind that their networks and equipment is protected through our digital access control
- Our landlords – only authorised individuals will be allowed access to our sites View further information here
- Reduced carbon footprint – through fewer journeys by improved management of who goes out and when to our sites.
