Foundations
The bedrock every energy professional shares. Start here to understand what energy is, how it's measured, the rules of the UK system, and the disciplines that underpin everything in Levels 2 and 3.
01Introduction to Energy Management9 lessons · 68 minWhat energy is, how it's measured, why we manage it, and how to turn a saving into a decision. The foundation course for the whole platform.02Mass & Energy Balances16 lessons · 138 minThe universal method behind every audit, diagnosis and M&V calculation: drawing a boundary, tracking what goes in and out, and never losing a kWh.03Electrical Science Refresher10 lessons · 82 minVoltage, current, power factor, three-phase basics and the electrical concepts that recur across motors, lighting and metering.04Monitoring & Targeting (M&T)13 lessons · 111 minTurn meter data into action: baselines, energy signatures, regression against drivers, exception reporting, and automatic M&T (aM&T) software.05UK Energy Regulation & Context11 lessons · 87 minESOS, SECR, the Climate Change Levy, EPCs/MEES, carbon budgets and the policy landscape shaping UK energy decisions.06Carbon Accounting Fundamentals11 lessons · 95 minHow organisations measure their emissions: scopes 1, 2 and 3, emission factors, the GHG Protocol and ISO 14064, market versus location-based reporting, and building a footprint that survives scrutiny. The measurement language every net-zero conversation assumes.

System Deep Dives
Roll up your sleeves. Each course takes a major energy-using system — boilers, HVAC, motors, compressed air and more — and teaches how it works, where it wastes energy, and how to fix it.

Leadership & Strategy
Move from running systems to leading change. Strategy, policy, investment, financing, procurement and the people skills to drive an organisation toward net zero.

A peer to Levels 1–3, not a fourth tier
Or go deep on one sector
The same principles applied to one industry at a time — its processes, its energy benchmarks, and the regulation unique to it.
Industrial

The process courses assume this grounding.02Energy Management in Breweries13 lessons · 143 minThe brewing process and where energy enters it, brewery-specific benchmarks, and the heat-recovery and refrigeration opportunities unique to a brewhouse, capped with a full brewery energy audit. Assumes the Food & Drink Foundations course.03Energy Management in Food Manufacturing11 lessons · 122 minHow a food factory uses energy line by line, specific energy per tonne, and the cooking, freezing and heat-recovery opportunities the sector reliably offers, capped with a full factory energy audit. Assumes the Food & Drink Foundations course.04Energy Management in Dairies13 lessons · 143 minMilk through pasteurisers, separators, ice water and (on powder sites) the sector's hungriest unit operation: dairy-specific loads and benchmarks, the spring flush, whey and co-products, and the regeneration and ice-bank opportunities unique to dairy processing, capped with a full dairy energy audit.
