Unlock measurable energy savings and control with AI-powered fused spurs

In commercial buildings, wired-in appliances like heaters, and boilers quietly drain energy, running when no one needs them. Traditional fused spurs can’t prevent this. But now, you can.

AI-powered fused spurs give you automated energy savings, real-time usage data, and remote management of these often-forgotten appliances, helping you reduce operational costs and carbon emissions.

What is a fused spur?

A fused spur (or fused connection unit) is a wall-mounted outlet used to power a single, often high-energy, fixed appliance.

You’ll often find them tucked behind walls or cabinets, connected to:

  • Hot water heaters
  • HVAC units
  • Extractor fans
  • Electric radiators

They’re hard to monitor, and harder to control.

This creates a blind spot  for facilities and sustainability teams trying to reduce building-wide energy consumption.

 

The problem: Invisible power drain

Traditional fused spurs are passive. Once something’s wired in, it often stays “on” indefinitely - sometimes 24/7. That leads to:

  • Unnecessary energy use during unoccupied hours
  • Increased maintenance from overheating or overuse
  • No visibility into how or when devices are being used
  • Higher energy bills and emissions.



The solution: Smart fused spurs for automated appliance control  

measurable.energy’s smart fused spurs automatically detect and eliminate energy waste. Using AI and real-time data, the system:

 

 

Simple to install, easy to scale

We know what you’re thinking: “This sounds great, but it probably means downtime, rewiring, and extra cost.”
Not with us.

  • Drop-in replacements
    Our fused spurs are designed to replace existing units with minimal disruption - no complex retrofits or infrastructure changes needed.
  • Wi-Fi enabled
    They connect securely to your existing Wi-Fi network, so there’s no need for separate gateways or cabling.
  • Fast rollout, lower cost
    Compared to other smart building upgrades, our fused spurs are far more cost-effective, and easier to deploy at scale.

Quick to install, easy to manage, and designed to deliver ROI fast.

 

But what about? 

“My electric radiators already have built-in timers.”
That’s a good start - but difficult to manage at scale. They get changed and devices switched to always-on without you knowing. And what if you have hundreds to manage? And exactly how much energy reduction are your timers enabling? It is impossible to know. Our fused spurs measure energy consumption 50 times a second and hence tell you exactly how much you are saving.

“What about Legionella risk from turning off hot water tanks?”
There is no risk of legionella from turning off hot water devices overnight and at weekends, however, consideration is needed for longer timeframes.

Our system can be configured to ensure essential appliances run according to health and safety guidance. You stay compliant, while still cutting unnecessary out-of-hours use.

“Can I cut power at the fused spur to an AC unit?”

Yes, it’s safe to cut power to an AC unit at the fused spur or plug socket. While startup does cause a brief surge in current, the energy, cost, and emissions savings from turning units off during extended downtime far outweigh any impact from restarting.

 

Proven impact: Real results from real sites

measurable.energy’s smart fused spurs are already helping organisations cut energy waste, lower emissions, and improve operational control. Here's what recent customer data shows:


How AI-powered fused spurs help you

 

Instant energy savings

Each smart fused spur saves an average of 2.1kWh per day with automated schedules active.

Average daily savings can be higher depending on the appliance type and usage patterns.

Appliance-level control

Switch off specific heaters, fans, or pumps automatically based on real usage patterns - no more blanket shutdowns.

Fast payback

Customers can reach ROI in just 81 days, depending on number of devices and usage patterns.

Built-in reporting

Track usage and emissions at the individual appliance level - data you’ve never had before.

No more guesswork

Know exactly what’s using power, when, and why with automated control over every appliance.

Quick Maintenance

Power trip alert? You’ll know instantly, no manual checks or downtime surprises.

 

Why it matters

If you’re managing energy, you’re under pressure to:

  • Cut carbon emissions
  • Lower energy bills
  • Hit net zero or ESG targets
  • Report accurately and in real time

Smart fused spurs help you hit all of these without major retrofits or disruption.
