RESULTS & SAVINGS
Measured, Verified Savings – Not Guesswork
DLH programmes are designed and validated using recognised best practice for measurement and verification.
Typical performance
Multi‑retailer pilots and roll‑outs show average refrigeration energy savings of 13% or more, with higher savings where plant is starting from a sub‑optimised baseline.
In one 220‑site deployment, DLH delivered around 13–14% energy savings on refrigeration.
In another 280‑site estate, average monthly energy savings per site were estimated at over £1,500 against a subscription cost of around £500, giving net savings of c. £1,000 per site per month and a projected five‑year benefit of approximately £16.9m.
How we verify savings
Savings are independently checked using IPMVP‑aligned methods.
Baseline creation: at least a year of historical daily energy data and ambient temperature is used to build a “business as usual” model for each pack or site.
Regression analysis: we model the relationship between cooling energy use and drivers such as outside temperature and trading pattern to forecast what consumption would have been without DLH.
Sub‑metering: where available, pack‑level data allows granular comparison before and after optimisation.
Ongoing reporting: real‑time dashboards show kWh reduction, cost savings and associated CO₂avoided for ESG and net‑zero reporting.
