SMART SOCKETS - RETROFIT ENERGY CONTROL
Smart Sockets for Businesses: Stop Paying to Power Empty Rooms
Smart sockets are plug-level devices that replace standard sockets and automatically switch off appliances when they’re not needed, cutting wasted energy without rewiring. Four Seasons HVAC designs, supplies and installs them for offices, hotels, retail, education and stadiums throughout London, South East Essex and East Anglia, starting with a free on-site survey.
Plug-level smart sockets that find the energy your building is wasting — and switch it off automatically. No rewiring, no downtime, savings from the day they're installed.

THE PROBLEM
Your building is losing money in places the meter never shows you.
Most commercial energy waste isn't the boiler or the chiller plant — it's the everyday sockets, screens, fridges and fittings left running around the clock.
Up to 40% of a building's electricity is hidden plug-load energy, and nearly half of that is wasted outright.
Small power control.
Schedule, automate or remotely switch off plug-in appliances — fridges, TV's, vending machines, catering kit — using the wiring you already have.
Lighting automation
Occupancy-based scheduling that dims or kills lighting in offices, corridors and hospitality areas the moment a space empties out.
Refrigeration intelligence
Compressor-aware control for drinks fridges and chillers cuts consumption while protecting stock and equipment life.
Centralised monitoring
One dashboard for the whole estate — real-time usage, per-device control, and the data to prove exactly where savings came from.
WHO WE SERVE
Built for the sites where plug load waste hides best.
95% — Construction & site compounds
Electricity on site goes to plug-in equipment, and roughly half of it is wasted. Automate temporary accommodation from day one.
40% — Commercial offices
Office electricity from plug loads is often left running unattended - such as monitors, printers, TV's, PC's. Get fast ROI across desks and meeting rooms.
Real-time — Retail
Fridges, displays and store equipment left on overnight. Track and cut the waste as it happens.
30% — Hospitality
Kitchens, bars and guest rooms controlled without ever touching the guest experience. TV's, Fridges, Towel Rails
40% — Educational settings
Energy wasted outside teaching hours. Control classrooms, PC's, printers, monitors and IT suites to cut cost, carbon and fire risk.
HOW IT WORKS
From socket to strategy, in three steps.
Every device gets recognised by its own energy signature, then brought under automatic control, with a human team watching the data behind it.
1. Survey & identify
A detailed on-site consultation maps your building, its operating patterns and its energy goals — pinpointing where the biggest savings are hiding, without touching daily operations.
2. Install & automate
Devices replace your existing fittings and self-commission on site. No invasive electrical work, no downtime — savings start from the moment they go live.
3. Optimise & eliminate
A dedicated success manager keeps reading the usage data, tightening schedules and flagging anomalies so the system keeps finding savings long after installation.
Why retrofit beats rewiring.
Traditional electrical upgrades are slow, costly and disruptive. A retrofit removes every one of those barriers.
SMART SOCKETS RETROFIT
Uses existing wiring — Devices replace standard fittings on your current electrical infrastructure — no invasive work.
Installed around operations — Deployment is scheduled around live environments for minimal disruption to guests or staff.
Rapid rollout — Large sites are upgraded quickly, without complex project planning or long procurement.
Immediate savings — Energy reduction begins the moment devices are commissioned.
TRADITIONAL UPGRADES
Rewiring required — Often means invasive electrical work and significant site preparation.
Operational disruption — Installation frequently affects day-to-day building use and access.
Long rollout timelines — Multi-site projects can take months to complete.
High upfront cost — Significant capital is usually required before a single pound is saved.
BEYOND ENERGY
The same system that cuts waste also makes your building safer.
Once every appliance is visible and controllable, the benefits reach well past the energy bill.
Fire risk detection
AI-powered monitoring flags faulty appliances and overloaded circuits early, lowering fire risk and the cost of ongoing compliance.
Asset & space utilisation
See how spaces are actually occupied in real time, so heating, lighting and power run only where they're needed.
Behaviour change
Live LED cues, dashboards and socket-level visibility turn awareness of wasted energy into everyday action.
CASE STUDY
London Stadium
Hospitality suites and concourse areas were retrofitted with intelligent sockets and switches, giving the facilities team central control of hundreds of devices — without ever disrupting match-day or event operations.
66% — Customer-verified energy saved
600+ — Devices installed across the site
<12mo — Full return on investment

FAQ's
-
What are smart sockets for business? Smart sockets are plug-level control devices that replace standard sockets and fittings. They recognise each connected appliance by its energy signature and switch it off or schedule it automatically when it is not needed, cutting wasted energy without rewiring.
-
How much energy can smart sockets save? Customer-verified reductions of up to 70% have been recorded, and the London Stadium project saved 66% across more than 600 devices. Results depend on your site and equipment, which is why we start with a free on-site survey and a tailored savings report.
-
Do smart sockets require rewiring? No. Smart sockets replace your existing fittings on your current wiring and self-commission on site, so there is no invasive electrical work. Installation is scheduled around your operations to avoid disruption.
-
How long does it take for smart sockets to pay for themselves? Typical payback is around 12 months. At London Stadium the full return on investment was achieved in under 12 months.
-
Which businesses benefit most from smart sockets? Sites with lots of plug-in equipment left running benefit most: commercial offices, hotels and hospitality venues, retail stores, schools and universities, construction site compounds and stadiums.
-
Do you install smart sockets across the UK? Yes. Four Seasons HVAC designs, supplies and installs smart sockets for all business types throughout the UK. Book a free on-site survey to get started.
