Most homeowners focus on boilers, insulation, or windows to boost their EPC rating. But lurking in every home are energy vampires: devices that consume electricity even when switched off. These are called phantom loads, and they quietly inflate your bills while dragging down your EPC score.

What Are Phantom Loads?
Phantom loads, also known as standby power, refer to the electricity used by devices when they’re plugged in but not actively in use. Examples include:
TVs, gaming consoles, and set-top boxes
Computers and laptops on standby
Chargers left in sockets
Smart appliances and microwaves with clocks
Wi-Fi routers and printers
Even small devices add up over time, silently impacting energy efficiency.
How Phantom Loads Affect EPC Ratings
EPC calculations account for energy consumption patterns in the property. While insulation and heating efficiency carry the heaviest weight, unnecessary standby energy usage can:
Increase estimated annual energy costs
Raise carbon emissions in the EPC assessment
Reduce overall energy efficiency score
In short, phantom loads may not be visible, but they subtly prevent your EPC rating from reaching its potential.
Top Strategies to Minimise Phantom Loads
1️⃣ Unplug Devices When Not in Use – Easy and effective.
2️⃣ Use Smart Plugs or Timers – Automatically cut standby power.
3️⃣ Choose Energy-Efficient Appliances – Look for A+++ rated models.
4️⃣ Power Strips for Multiple Devices – One switch can kill multiple phantom loads at once.
5️⃣ Educate Household Members – Awareness is key to reducing waste.
Even small reductions in phantom energy can improve your EPC rating and cut bills.
