Totem is an energy-management system for purpose-built student accommodation (PBSA), operated by Chaahk Limited. It gives operators real-time visibility and room-level control of electric heating, cutting the energy wasted heating empty rooms.
In electrically-heated PBSA, heating can be up to 70% of running costs, yet all-inclusive rent removes any resident incentive to manage it and rooms sit empty around 30% of the year. Totem's control units retrofit behind existing wall sockets in about 15 minutes each, with no rewiring and no damage to the building, and are managed from one dashboard.
At its flagship deployment — Bargate House in Southampton (122 rooms, operated by Unilife, live since January 2026) — Totem has cut building-wide electric heating energy by over 54%, with a payback under two years, and publishes the savings live, updated weekly.

Ready-made angles, each backed by live, verifiable data. Happy to provide figures, an interview and comment on any of them.
Angle 1 — the invisible cost
In electrically-heated PBSA, heating can be up to 70% of running costs, but operators are blind to it until the quarterly bill lands. All-inclusive rent removes any student incentive to manage it, and rooms sit empty around 30% of the year with the heating still on. Totem makes that waste visible and controllable room by room.
Angle 2 — the 2030 EPC deadline, the cheaper route
EPC C is due across the rented sector by 1 October 2030. For electrically-heated buildings the low-cost, non-invasive path is controls and monitoring — the reformed EPC's Smart Readiness metric — rather than capital-heavy fabric works. It's the route the market isn't discussing yet.
Angle 3 — radical transparency
A real 122-room building — Bargate House, Southampton, operated by Unilife — publishes its energy savings live and refreshed weekly for anyone to check: over 54% building-wide since January 2026. Verifiable data is rare in a sector full of unaudited claims.
Angle 4 — retrofit without disruption
No rewiring, no structural work, no damage to the building. A control unit fits behind the existing wall socket in about 15 minutes, installed by any qualified electrician, during term time, with residents in place.
