Student accommodation providers face a triple challenge. They need to deliver comfortable, modern living environments, stay ahead of tightening regulatory requirements, and cut costs in the face of rising energy bills. At the same time, they are under growing pressure to support universities’ ambitious net zero strategies.
Many operators are already investing in retrofits, electrification, and smarter building management. But compliance deadlines and budget constraints mean not every solution is realistic to implement at speed. What if there were a way to reduce emissions and costs immediately, without new capital expenditure, and while future-proofing estates for the long term?
That’s where Voltalis comes in.
Flexibility that goes further than compliance
Voltalis provides intelligent demand-side flexibility. In practice, this means helping buildings use less electricity during peak times, when power is most expensive and carbon-intensive, without affecting comfort or student experience.
By installing smart control modules at no upfront cost, Voltalis enables short, automatic adjustments to heating, cooling and hot water systems. These adjustments are invisible to occupants but deliver up to 15% reductions in electricity use, verified carbon savings, and compliance with grid-balancing and decarbonisation requirements.
For estate managers, that means:
- Immediate financial returns: Average 15% reduction in electric heating and cooling costs with no capital investment
- Verified Scope 2 emission reductions that contribute directly to net zero reporting
- Zero operational disruption to student comfort or accommodation management
- Automatic compliance with grid-balancing requirements and future regulatory frameworks
- Revenue opportunities through participation in grid flexibility markets
Real results: University of Wales Trinity Saint David
In autumn 2024, Voltalis partnered with the University of Wales Trinity Saint David to install its technology across over 100 student accommodation rooms. The 15-minute installations required no rewiring or building modifications, making them ideal for heritage properties.
Within six months, the results exceeded expectations:
- 13% reduction in electricity consumption across two accommodation blocks
- Over 5,000 grid support events delivered automatically
- Significant Scope 2 emission reductions contributing to decarbonisation targets
- Zero student complaints despite consistent system operation
- Seamless integration even in buildings dating back over 200 years
As Daniel Priddy, Head of Sustainability, explains: “Since installing the Voltalis solution, we’ve achieved a 13% reduction in electricity use across our student accommodation – all without any changes in comfort or behaviour. That’s rare, especially in a heritage university with complex infrastructure. What’s even more impressive is that despite the system running consistently, there were no complaints from users.”
The strategic advantage: from cost centre to grid asset
Traditional energy management treats buildings as consumers. Voltalis transforms them into active grid participants, creating value from flexibility while reducing costs.
As the UK grid becomes increasingly renewable-dependent, the ability to shift demand intelligently becomes a strategic asset. Student accommodation, with its predictable usage patterns and distributed footprint, is perfectly positioned to capitalise on this transition.
For PBSA providers managing multiple sites, this represents a step-change in how accommodation can contribute to both institutional sustainability goals and operational efficiency. It’s not just about using less energy, it’s about using energy smarter.
Beyond compliance, towards resilience
The role of student housing in the energy transition is often overlooked. Yet PBSA buildings are both high-consumption and highly replicable across the UK estate. With solutions like Voltalis, operators can move beyond box-ticking compliance to become active contributors to grid stability, carbon reduction, and cost resilience.
Flexibility is not just about balancing the grid. It’s about future proofing your estate against rising costs, regulatory scrutiny, and the volatility of a changing energy system. Early adopters don’t just achieve compliance, they position themselves as leaders in the sector’s transition to smarter, more sustainable operations.
Scaling success across the sector
With over 1.5 million devices already managing flexibility across Europe and UK, Voltalis is expanding its university partnerships following the UWTSD success. Similar deployments are underway with other institutions, demonstrating the scalability and replicability of demand-side flexibility in student accommodation.
All together better.
