Energy in dark kitchens and delivery-only brands

Delivery only kitchens, ghost kitchens, kitchen pods and multi brand operators cooking for Deliveroo, Uber Eats and Just Eat. No dining room means no front of house heating or lighting, but everything else is intensified. Kitchen density is higher, trading hours are longer, extraction runs the whole session, and many units are all electric with no gas supply at all, which puts the entire bill on the more expensive fuel. Sector data for large multi cuisine hot food kitchens runs to 8,000 to 14,000 kWh of electricity a month. Figures below are estimates at 25p per kWh electricity, 7p per kWh gas and about £365 a year standing charges.

Common energy challenges for dark kitchens and delivery-only brands

  • Very long trading hours, often late morning through to well past midnight

  • Multiple brands cooking from the same line, so equipment is rarely allowed to go cold

  • All electric units carrying the whole cooking load on the more expensive fuel

  • Extraction running continuously in a sealed unit with no natural ventilation

Energy saving tips for dark kitchens and delivery-only brands

  1. 1

    Map which brands actually sell after 10pm and power down the stations that do not

  2. 2

    Choose induction over solid tops where you can, in an unventilated pod it cuts both the cooking load and the extraction load

  3. 3

    Put the extraction on variable speed tied to the cooking line, in a dark kitchen it is often the second biggest electrical load

  4. 4

    Consolidate refrigeration across brands where menus overlap, two half empty walk-ins cost more than one full one

  5. 5

    If your unit has no gas supply, get your electricity contract reviewed more often, an all electric site is far more exposed to a bad rate
