Who To Contact and When

Whether you have questions about installation, need help with your service, or have other concerns, this guide will help you know who to contact and when. Please remember that SIRO is a wholesale provider, which means any queries relating to internet service, pricing, speed levels are better answered by your preferred retailer (Sky, Virgin Media, Vodafone, Digiweb etc.).

When to contact your broadband provider

SIRO works closely with our broadband retailer partners, who handle your service and manage all customer inquiries. If you need assistance, please contact your broadband provider directly. They will coordinate directly with SIRO for any technical support required. 

Here are some scenarios when you should contact your broadband provider: 

  • Installation Queries: For specific technical questions about your installation, such as cabling or equipment sizing, discuss these with the installer during your appointment.
  • Appointment Details: For information about your installation appointment, including the time and date, contact your broadband provider. 
  • New Tenant/SIRO Number request: If you are a new tenant or need your SIRO number, check your previous bills or ask your provider to initiate the new tenant process if there is an active line in the premise. 
  • Issues with Installation: If there are problems with the installation, such as late arrival or cancelled appointments, report these to your provider. 
  • Faults and Service Issues: For issues with your broadband service, your provider will help diagnose the problem. They will contact SIRO directly if technical support is needed and have the latest updates on any known faults or outages.
