Electricity Bill Analyzer

Your kWh consumption appears on your electricity bill, usually on the first page. It may be listed as "units used" or "electricity consumption". If you only have the cost, divide your total bill (excluding standing charges and VAT) by your unit rate to get an approximate kWh figure. For the most accurate analysis, use 12 months of billing data.

The unit rate is what you pay per kWh of electricity consumed. For commercial customers in 2026, typical rates range from 20p to 35p per kWh depending on your tariff, contract, and consumption volume. You will find this on your bill, often shown as "unit rate" or "day rate". Some contracts have different rates for day and night usage.

Peak hours are typically 7am to 7pm on weekdays when electricity demand and prices are highest. Off-peak hours are evenings, nights, and weekends when rates are lower. Businesses that can shift energy-intensive processes to off-peak hours, or use battery storage for peak shaving, can significantly reduce their bills.

Solar panels generate free electricity during daylight hours, directly reducing the amount you buy from the grid. A well-sized system typically offsets 50-70% of daytime consumption. Any excess can be exported for income via the Smart Export Guarantee. Combined with battery storage, you can also reduce peak-time consumption.

The standing charge is a fixed daily fee for being connected to the electricity grid, regardless of how much you use. For commercial properties, this typically ranges from 30p to 80p per day. Solar panels do not eliminate standing charges, but the overall bill reduction from reduced consumption far outweighs this fixed cost.
