Understanding how energy is used and wasted across your business is the first step to reducing costs and carbon.
Below are the most common questions we’re asked by multi-site organisations looking to improve energy performance.
Avoidable energy waste is the unnecessary use of electricity or gas that does not contribute to operations, productivity or customer experience. It typically occurs overnight, outside trading hours, or through inefficient equipment and controls.
Most UK businesses waste between 8% and 20% of their total energy consumption, often without realising it. In multi-site estates, this can represent a significant hidden cost.
Common causes include:
Overnight energy waste is energy consumed when a building is unoccupied. This can account for 30–40% of total usage in some businesses and is often one of the biggest savings opportunities.
Businesses can reduce energy costs by:
FUNNL-E analyses half-hourly electricity and gas data, along with operational patterns, to identify where energy is being used unnecessarily. This is presented in kWh, cost and carbon terms.
We typically require:
We typically require:
Initial insights can usually be delivered within a few days of receiving your data.
No. The initial analysis is carried out using your existing energy data, with no upfront hardware required.
Most organisations achieve:
Retail sites often waste energy through lighting, HVAC systems and overnight baseload. Optimisation can deliver significant savings across multi-site estates.
Hospitality businesses typically face high energy usage from kitchens, refrigeration and HVAC systems, with significant opportunities in operational optimisation.
Care homes require consistent heating and hot water, but often have inefficiencies in system control and usage patterns that can be optimised.
Half-hourly data records energy usage every 30 minutes, providing detailed insight into how and when energy is consumed.
Voltage optimisation reduces incoming electrical voltage to a more efficient level, helping reduce energy consumption and improve equipment performance.
Solar PV generates electricity on-site, reducing reliance on grid energy and lowering electricity costs over time.
A BESS stores electricity for later use, allowing businesses to use cheaper off-peak energy or maximise solar generation.
Most businesses don’t have a consumption problem—they have a visibility problem.
