What Happens After You Contact Us?

Once we receive your enquiry, we review the site details, the type of security service required and the hours of cover. If needed, we may ask for further information about access arrangements, site activity, risks or start dates so the requirement is understood properly before any deployment is agreed.

From there, we discuss suitable options, explain how the service would operate and prepare a quotation where appropriate. Before officers are deployed, arrangements are confirmed with the client so there is a clear understanding of duties, reporting lines and site procedures.

Emergency and Urgent Security Requests

Some enquiries are planned in advance, while others involve urgent cover following a break-in, staffing issue, alarm activation or unexpected site risk. Urgent requests can be discussed with our team, and short-notice deployment may be possible depending on the location, service required and officer availability.

Information That Helps Us Prepare a Quote

• Property or site location
• Type of premises or operation
• Required security service
• Expected start date
• Hours of cover required
• Temporary or long-term requirement
• Any known site risks or access issues

Providing this information early helps us assess staffing, supervision and reporting requirements more accurately.
