Business Energy Bills Explained (Ireland)
Commercial electricity and gas bills can be confusing — unit rates, standing charges, capacity charges, levies and VAT. This guide explains what each part means and how to spot opportunities to reduce costs.
What you pay
Your total is made up of usage (kWh), fixed charges, and taxes/levies.
What matters most
Unit rate and standing/capacity charges are usually the biggest levers for savings.
When to check
Renewals are key — rolling onto costly rates is common if you don’t review in time.
What’s on a business energy bill?
Below are the most common sections on Irish commercial electricity and gas bills. Your bill layout may vary by supplier, but the parts are broadly similar.
1) Unit rate (€/kWh)
This is what you pay for each unit of energy used. A small change in unit rate can make a big difference to annual cost.
Always compare the unit rate on your bill to your contract or renewal offer.
2) Standing charge
A fixed daily charge (often per meter) that applies even if your usage is low. It can add up quickly — especially for
multiple sites or low-usage premises.
3) Capacity / demand charges
Some commercial bills include charges linked to agreed capacity or peak demand. If your capacity is set too high, you may
be paying more than needed.
4) Usage & billing period
Your kWh usage is shown for the billing period. Check if your bill is estimated or based on an actual reading, and make
sure the dates match your expected period.
5) Levies, fees & VAT
Bills may include regulated levies and taxes plus VAT. These are common and usually not negotiable, but it’s still worth
understanding how they contribute to your total.
6) Contract & renewal information
Many businesses overpay at renewal. If you’re unsure what contract you’re on or when it ends, a quick review can prevent
rolling onto costly rates.

Business energy bill FAQs
How can I tell if my business is overpaying?
Compare your unit rate (€/kWh), standing charges and any capacity/demand charges against your contract or renewal offer.
If you’re unsure what tariff you’re on or when you renew, a bill review can quickly highlight potential savings.
What’s the difference between unit rate and standing charge?
The unit rate is what you pay per kWh of energy used. The standing charge is a fixed daily cost that applies regardless
of usage. Businesses often focus on unit rate but fixed charges can also impact total cost.
Why do bills include capacity or demand charges?
Some commercial agreements include charges linked to agreed capacity or peak demand. If the capacity is set too high for
your actual needs, it may increase your bill. A review can confirm whether this looks appropriate.
Do you need my full contract to review my bill?
Usually, a recent bill contains enough information to understand your current rate and charges. If anything is missing,
we’ll let you know what’s needed — in the simplest way possible.
