How it works
Your building already has everything it needs
If you run electric heating or cooling, you’ve got the equipment we work with, from electric radiators and heat pumps to complex HVAC systems. We connect to what’s already there, no replacements and no rewiring required.
One platform. Every device live.
Our technology sits alongside your existing appliances and devices and starts sending data within hours of installation. Your estates team gets a single dashboard showing every connected appliance, real-time consumption, and exactly how much electricity demand response saves you.
Every building you operate, working together.
Offices, hotels, retail sites, student accommodation, stadia, leisure centres. Voltalis works across your entire portfolio rather than one site at a time, so the value compounds with every building you add. You manage it all from one place.
Built into Britain’s energy system.
When the National Energy System Operator (NESO) needs to balance supply and demand, it sends signals to Voltalis. We respond in seconds by gently adjusting consumption, where appropriate, across every connected building at once. Your operations don’t change, and occupants don’t notice a thing.
Zero cost to you.
The electricity markets compensates us for the flexibility we deliver by activating demand response, which is how we fund the our technology, its installation, and operating the service at no charge to you. You keep 100% of the electricity and carbon savings and contribute to a cleaner, more resilient grid. We take care of the rest.
Unlock the untapped value in your building’s infrastructure.
Connect to UK flexibility markets via your existing infrastructure. Complete control & visibility, savings and instant ESG progress – fully funded.
Zero capital, zero disruption, total comfort.
Whether you’re a University or a PBSA, we connect your heating systems or upgrade your legacy heating stock for – all funded by us and no change in comfort.
Save energy & increase your comfort without lifting a finger.
Residential properties can connect to our platform via our smart thermostats and save electricity & carbon emissions while supporting the grid.

“The more I heard about Voltalis, the more it made sense— why wouldn’t we do this? It’s free for us, saves our tenants money, and helps cut carbon emissions. It ticks every box. This project is a win-win- win. It’s exactly the kind of innovation we need in social housing.”
“There is no cost to Grampian, there is cost reduction for our tenants, and because I deal with sustainability, we are reducing the carbon impact of our tenants and therefore Grampian as an organisation. It ticked so many boxes. When you have a company come to you and say, ‘We have a great product, it’s going to help your tenants, it’s going to help the environment, and by the way, it doesn’t cost anything,’ why on earth would you or anybody else not install it?”
“At YMCA Derbyshire, we’re committed to creating safe, supportive, and sustainable environments for our residents and the communities we serve. Partnering with Voltalis allows us to take a major step forward in reducing our carbon footprint while keeping energy costs low for those who need it most.”
“Working with Voltalis is really easy, and I think as a club, if we’d not taken that opportunity, it would’ve been like missing an open goal. Here at Bolton Wanderers, we’re proud to be the first professional football club to be working with Voltalis. ”
“ From day one, Voltalis began delivering savings — not just in energy and carbon, but in operational effort too. The university team gained greater control over their electric heating systems while benefiting from automatic demand-side support. What we value most is the simplicity. It makes traditional radiators smart and keeps them smart — without asking anything of our users.”
“We’ve achieved impressive reductions in our electricity consumption since activating the Voltalis system across our student housing. The install was frictionless, and it has been optimising our radiators seamlessly in the background, delivering energy efficiency, cost savings and sustainability without disrupting the student experience.”
