When Storm Goretti hit in January 2026, more than 250,000 customers lost power, and the Government told Parliament the storm hit power and telecoms, particularly in rural communities in the south-west. Hansard

Mobile masts, street cabinets and the equipment behind them need mains power. When it fails, each site runs on its backup batteries or generator for as long as they last. As landlines move to digital and more of daily life moves online, that matters to everyone, including people trying to reach the emergency services.

Operators can already estimate which sites are exposed to flooding or high winds. What is harder to see is the real state of the backup at each site, and which sites in the path of a forecast storm will run out first. Ofcom's resilience guidance, updated in June 2026, now sets out what it expects of mobile operators on backup power at their sites. Ofcom

Three inputs, one score for each site.

1. 1

   Exposure: how exposed is the site?

   We score each site's exposure to flooding, wind and heat from open flood, satellite and climate data.

2. 2

   Forecast: what is coming?

   We bring in operational weather forecasts as each storm approaches.

3. 3

   Endurance: how long will the backup last?

   We use the real state of each site's backup power, from our low-cost sensor unit or from monitoring the operator already has in place. Endurance is measured, not assumed.

We are inviting a small number of early partners to shape Stormproof: people who would use it, host it, test it or build on it. What you tell us stays confidential. We never publish site locations, host names or who we spoke to.

Network operators and altnets

Tell us how you plan for storms now, which sites worry you, and what a survivability score would need to show to be useful. We want to hear from operators of every size, including community and rural networks, mobile operators and towercos, and owners of street cabinets. A structured conversation is all we ask.

Sector bodies and researchers

If you work on network resilience, power and telecoms dependency, or climate adaptation, we would value your challenge on our method and the chance to compare notes. We will publish our validation results openly.

Technology and data partners

If you make power monitoring, cabinet monitoring or backup power equipment, or hold data that could sharpen the score, talk to us about how Stormproof could work alongside what you already do.

Start with a short conversation, with no commitment and no sales pitch. Tell us what you are working on and what you would need.

Stormproof is led by Callum Wright, director of Quantum Risk Solutions.
