Clear tools for everyday energy decisions

UK Energy Toolkit was created to make electricity costs easier to understand. Bills can be confusing, and it's often hard to tell what an appliance, a car charge or a whole month of usage really costs.

Our free calculators use the figures from your own bill — we never assume or display rates as official prices. Our Excel spreadsheets then help you track usage, plan budgets and spot changes over time.

Everything is designed for UK homeowners, tenants, landlords, sole traders and small business owners who want practical numbers without jargon or subscriptions.
