Smart Tariffs Ireland (2026): Compare Smart Electricity Plans
Smart tariffs in Ireland use time-of-use electricity pricing, meaning the price you pay for electricity can vary depending on when you use it.
They can offer good value for households that are able to move electricity consumption into cheaper off-peak periods and avoid expensive peak hours.
The best smart electricity tariff depends on your household usage pattern, peak and off-peak rates, standing charges and total annual electricity cost.

What Is A Smart Electricity Tariff?
A smart electricity tariff is an electricity plan designed for households with a smart meter.
Unlike a traditional standard tariff, where the same unit rate may apply throughout the day, smart tariffs normally use different rates during different time periods.
These may include:
- Peak rate – generally the most expensive electricity period
- Day rate – the normal daytime electricity price
- Off-peak or night rate – lower-cost electricity during designated periods
The exact pricing periods and electricity rates vary between suppliers and plans.
How Do Smart Tariffs Work In Ireland?
A smart meter records how much electricity your household uses at different times of the day.
This allows electricity suppliers to offer time-of-use plans where different electricity prices apply during different periods.
Households that can move flexible electricity usage into cheaper periods may be able to reduce their annual electricity costs.
Examples of flexible electricity usage include:
- EV charging
- battery charging
- dishwashers and washing machines
- some electric heating loads
- other electricity use that can be scheduled overnight

Are Smart Tariffs Cheaper?
Smart tariffs can be cheaper, but they are not automatically the cheapest electricity option for every household.
The potential saving depends on how much electricity you can move away from expensive peak periods and into lower-cost off-peak periods.
A household that uses a large amount of electricity during expensive evening periods may pay more on some smart tariffs.
For this reason, the best comparison should consider your total expected annual electricity cost, not simply the cheapest advertised night rate.

Who Can Benefit From A Smart Electricity Plan?
Smart tariffs can be particularly useful for households with flexible or higher electricity usage.
These may include:
- electric vehicle owners
- solar and battery households
- heat pump homes
- households using significant electricity overnight
- homes that can schedule appliances outside peak hours
However, the right tariff still depends on the household's complete electricity usage profile.
Peak, Day And Off-Peak Electricity Rates
Many smart electricity plans divide the day into different pricing periods.
Peak electricity rates are normally higher, while off-peak rates are designed to encourage households to use electricity when demand is lower.
The exact hours can vary between tariffs, so it is important to check the pricing periods before choosing a plan.

Smart Tariffs Vs Day/Night Electricity Tariffs
Smart tariffs and traditional day/night tariffs both offer different electricity prices at different times, but their pricing structures can differ.
A traditional day/night tariff generally has two main rates, while a smart tariff may include several pricing periods such as peak, day and off-peak.
The better option depends on when your household uses electricity.

Smart Tariffs For EV Owners
EV owners can often benefit from smart electricity plans with lower overnight or off-peak charging rates.
However, the cheapest EV charging rate does not automatically mean the cheapest overall electricity plan because daytime rates, peak rates and standing charges also matter.

Smart Tariffs For Solar And Battery Homes
Solar and battery households may use smart tariffs to combine lower-cost grid electricity with solar generation and battery storage.
The right tariff may depend on import rates, battery charging times, solar generation and export payments.

Smart Tariffs For Heat Pump Homes
Heat pump households often have higher electricity consumption, so unit rates and time-of-use pricing can have a significant effect on annual running costs.
Some households may benefit from moving suitable electricity consumption into cheaper periods.

How To Compare Smart Tariffs
When comparing smart electricity tariffs, review:
- peak electricity rate
- day electricity rate
- off-peak or night rate
- the hours when each rate applies
- standing charge
- your household electricity usage
- your expected total annual electricity cost
A plan with the cheapest off-peak rate may not be the cheapest overall tariff if the peak or daytime rates are considerably higher.
Should I Move To A Smart Tariff?
A smart tariff may suit you if your household can move a meaningful amount of electricity usage into cheaper periods.
Before switching, it is useful to understand when your household currently consumes electricity and whether you can realistically avoid expensive peak periods.
Households with EVs, batteries and other flexible loads can often have more opportunity to shift electricity usage than households with largely fixed consumption patterns.

Smart Tariff FAQs
What is a smart electricity tariff?
A smart electricity tariff is a time-of-use electricity plan where different rates can apply depending on when electricity is consumed.
Are smart tariffs cheaper?
They can be cheaper for households that move enough electricity consumption into lower-cost periods and avoid expensive peak rates. They are not automatically cheaper for every household.
Do I need a smart meter for a smart tariff?
Yes. Smart tariffs rely on smart meter usage data so electricity consumption can be charged according to different time periods.
What are peak and off-peak electricity rates?
Peak rates apply during higher-cost periods, while off-peak rates apply during designated lower-cost periods. The exact times and prices depend on the electricity tariff.
Are smart tariffs good for EV charging?
They can be particularly useful for EV owners who can schedule charging during cheaper overnight or off-peak periods.
Should I choose the smart tariff with the cheapest night rate?
Not necessarily. You should also compare daytime rates, peak rates, standing charges and total annual electricity cost.
How do I know if a smart tariff suits my home?
Review when your household uses electricity and how much consumption can realistically be shifted into cheaper periods. The best tariff depends on your complete electricity usage profile.
