    Could you please let me have a breakdown of how you have calculated an additional potential cost of £407 as it seems somewhat excessive.

    Thanks.

    Replied by: Marcin On 2025-07-25 Dear David,

    Thanks for your query. The article estimates the £407 annual cost from "vampire power" (standby consumption) based on a high example of ~2,370 kWh used idly per year, multiplied by a ~£0.172/kWh electricity rate (common in 2021 when published). This implies an average 270W continuous draw across devices, assuming a larger home with many left in standby mode, which could push totals higher if you have numerous high-draw items (e.g., multiple TVs, chargers, or DVRs). That said, now we have even more devices at home, and kids often have phones, tablets, headphone chargers, etc., which can add up. Typical UK standby losses are around £147 yearly per recent British Gas research. However, it's different for every household—some may have higher energy losses, while most might have way lower, as every case is unique. To cut costs, unplug chargers/TVs when not in use or use smart power strips.

    Best regards,
    Marcin
