Frequently Asked Questions for Utilities Operators

How quickly can we get started?

We'll set up your organisation's private administration console with sample data so you can see exactly how it works. Once you have your admin logins, you simply send registration codes to field engineers, control room staff, and contractors, and your organisation can be live in hours, not weeks.

Is our data secure?

Your data is hosted in a carbon-neutral, ISO-certified European data centre. With 24/7 monitoring, redundant power, and full GDPR and UK GDPR compliance, you can be confident your organisation's information is secure and always available.

Can you help us prepare our staff list?

Yes. Whether you have a workforce management export, CSV file, or spreadsheet, we'll convert your data into the Calling Tree format for you. All we really need is Name, Email, and Phone. We'll handle the rest and make rollout simple, including for contractor populations.

What number do messages come from?

Where available, we provide your organisation with a dedicated SMS or voice number. Engineers and staff can reply directly, and their responses appear instantly in your admin console. If a dedicated number isn't possible, we'll advise on the best alternative.

How many messages can we send?

Every package includes a generous allowance of messages per user. Our dedicated gateway can handle 2,400 messages per minute, fast enough to reach every depot, field team, and contractor across multiple sites in seconds, whether by SMS, voice, or both.

What languages are supported?

SMS can be sent in any language supported by your keyboard. Voice messages are available in most languages, with options for male/female voices and regional accents, useful for diverse field workforces across different regions.

Can we customise staff and contractor details?

Yes. In addition to standard fields (Name, Email, Team, Phone), you can add up to 20 custom fields. Utilities operators often use these for Depot, Region, Role, or Contractor Company. This makes filtering and targeting messages fast and precise during an incident.

Do you support staff directly?

We always support your nominated administrators. Depending on your plan, we can also provide direct assistance for field engineers and contractors, issuing app codes, troubleshooting, and handling usage queries. Every interaction is logged and reported back to you.

What reports can utilities operators see?

You'll see live delivery and response tracking every time you send a message. You'll also have access to rollout reports (who has installed the app), last-access stats, and complete administrator action logs for Ofgem compliance, HSE reporting, and internal governance.

Can we share documents with staff and contractors?

You can upload PDFs (incident response plans, safe working procedures, on-call rotas, site maps, emergency contact lists) to the admin console and make them available by depot, region, or role. The app stores them for offline access, so engineers can reach critical documents even when on a remote site with no signal.
