Summarise What Your Utility Bill Breakdown Actually Means

Unit rate, standing charge, estimated reading, a balance that's somehow both in credit and a worry: the bill is designed to confuse. Paste the breakdown and this explains each part in plain terms, whether your rates are typical, and what's actually driving the total. For anyone who pays the bill but couldn't say what half of it means.

**Make the bill legible without drowning the user in numbers:**
1. Explain the unit rate: what they are being charged per kilowatt-hour and whether it is typical
2. Explain the standing charge: what it covers and why it applies regardless of usage
3. Identify any additional charges or levies (environmental levies, VAT at 5%)
4. Show how the total figure was calculated in plain arithmetic
5. Flag any estimate vs actual reading discrepancy if present
