Product Update 8.14.2: Cut Standby Appliance Energy Costs with Voltaware’s Home Audit

Posted by 10 July 2025

We are happy to share one of our last updates yet. It offers a smarter and easier way to see how standby devices are quietly raising your energy bills.

With our new Standby Insights and Home Audit tools, Voltaware helps you reduce energy bills, unplug appliances on standby, and make small adjustments that have a lasting impact on both your wallet and the planet.

Standby energy, also called vampire or phantom load, is the small amount of electricity used by devices. This happens even when they are turned off or in low-power mode. Think TVs with a red light, phone chargers left in sockets, or printers left in sleep mode.

It may seem small, but these background drains can quietly cost households over £500 each year. That’s what we are here to help you fix.

What’s New: Clear Standby Insights in the Voltaware App

With our latest release (v8.14.2), the Voltaware app now includes a Standby Insights Dashboard - your personal hub for understanding and acting on unused power draw.

Here’s what’s included:

  • 📉 Estimated Annual Savings
    We calculate how much you could save by addressing standby energy in your home. In real cases, users save £69–100 per year simply by switching off unused appliances.
  • 💸 Current Standby Cost
    This figure reflects your real consumption data. It tells you how much you’re currently spending on power that’s going to waste - like a slow leak in your energy bill. It’s eye-opening, and it brings visibility to a problem that’s often ignored.
  • 📊 Your Standby Score
    Your score out of 100 shows how your household compares to an efficient average. The score is calculated using your unique usage patterns, and you’ll get clear suggestions on how to improve.
  • Think of it as your “energy efficiency credit score” - only more actionable.

    A Smarter Home Audit: Quick, Simple, and Personalised

    Alongside the new insights, we’ve introduced a brand-new feature: the Voltaware Home Audit.

    This step-by-step tool takes you through 8 key areas of your home - such as the living room, kitchen, garage, and bedrooms - to help identify devices that quietly consume power while on standby.

    ✅ How It Works:

    • The audit takes just 5 to 10 minutes to complete
    • Each room comes with common examples of devices that waste energy (like smart speakers, routers, and monitors)
    • You log your progress with simple “Changes made” or “No changes made” buttons
    • If no changes are made, you still receive practical tips to try later
    • It’s not about perfection - it’s about awareness and progress.

      What You'll Discover

      Each room is carefully tailored to highlight the most common standby offenders. While we don’t want to spoil all the details (we want users to explore the tool!), here are a few examples:

      • In the bedroom: phone chargers, smart alarm clocks, hair styling tools
      • In the kitchen: kettles, dishwashers, coffee machines, smart appliances
      • In the living room: TVs on standby, game consoles in idle mode, digital photo frames
      • In the garage: trickle chargers, tool stations, garage door motors
      • Outside: lights on timers, smart cameras, patio heaters
      • These devices may seem harmless, but many continue drawing power as long as they’re plugged in- even if they’re not being used.

        No Changes? Still Useful.

        Even if you go through the audit and don’t turn anything off, you still gain value. The app will show you smart, generalised recommendations to help reduce standby waste across your home.

        For example:

        • Switch to LED lighting - LEDs use up to 85% less electricity than traditional bulbs.
        • Use power strips with a master switch - This lets you turn off multiple devices at once.
        • Invest in timers or smart plugs - Perfect for routers, chargers, or heated towel rails.
        • These quick wins are accessible to everyone and don’t require deep technical knowledge or investment. They’re ideal for renters, families, and anyone looking to build better habits.

          Why It Matters: How Much Energy Do Appliances Use on Standby?

          You might be wondering: is it really worth switching off or unplugging things?

          The answer: absolutely.

          Many devices continue to draw 1-10 watts per hour on standby. This might not sound like much, but across dozens of devices and over a year, the impact adds up.

          Here’s how:

          • TVs on standby can use 3-5W constantly
          • Wireless speakers draw background power even when idle
          • Printers and routers often never switch off unless unplugged
          • Microwaves can use energy just for keeping the digital clock running
          • Voltaware gives you visibility over all of this. It helps answer questions like:

            • How much energy do appliances use on standby?
            • How much energy does a computer monitor use on standby?
            • What is the cost of leaving a TV on standby overnight?
            • These are real concerns - and now, you have tools to act on them.

              How to Get Started

              It’s simple:

              • 1. Open the Voltaware app
              • 2. Tap the Insights tab
              • 3. Select “Take action now” to begin your Home Audit
              • You’ll get instant feedback and a clear picture of where your energy is going.

                Why This Update Matters Now

                With rising electricity costs and growing interest in sustainable living, every bit of energy saved matters - for your budget and for the environment.
