NightSaver Electricity Rates explained
A NightSaver meter is the older two-rate meter that Irish homes have had since long before smart metering. It records day and night usage separately and bills the night register at a lower unit rate. Night hours are set nationally by ESB Networks rather than by your supplier, and they shift by an hour with the clocks: roughly 11pm to 8am in winter and midnight to 9am in summer.
NightSaver meters were installed mainly in houses with electric storage heating or a large immersion, where a big block of consumption could be moved overnight deliberately. That is still where they pay. If your night usage is only the fridge and a phone charger, the day rate on a NightSaver plan — which is normally higher than the flat rate on an equivalent 24-hour plan — will cost you more than it saves.
The number that matters is the share of your annual kWh that lands in the night window. As a rough rule, a NightSaver arrangement needs somewhere around a quarter of your usage overnight before it beats a good flat rate, and the more of your heating or hot water you can shift, the further ahead it gets. The estimates on this page assume 28% night usage, which is at the optimistic end for a household without storage heating.
The market for these plans is thin and getting thinner, because suppliers are steering new customers toward smart meters instead. If you have a NightSaver meter and few plans to choose from, it is worth asking ESB Networks about a smart meter upgrade: a smart tariff can reproduce a day/night split while giving you a much wider choice of supplier.
NightSaver Electricity Rates questions
What is the cheapest NightSaver electricity plan in Ireland?
At 4,200 kWh a year, the cheapest NightSaver electricity plan we track is Energysaver Nightsaver 16% from Electric Ireland, at an estimated €1,557.36 for the first year. It ranks 12 of 26 across all meter types, where the overall cheapest is €1,296.92.
How many suppliers offer NightSaver electricity plans?
We track 3 plans of this type from 2 suppliers: Electric Ireland, Yuno Energy. That is out of 26 electricity plans in total, so the choice here is narrower than the market as a whole. If your meter limits you to a short list, compare on ongoing cost as well as first-year cost before committing.
Do I need a particular meter for these plans?
Yes. Two-rate plans for older day/night meters, where everything used overnight is billed at a lower rate. You cannot choose your meter type from a supplier's website — it is determined by the hardware installed at your property by ESB Networks. Check a recent bill: it will show whether you are billed on one register or two, and a smart meter is normally identified by name. Annual costs assume 63% day, 28% night and 9% peak usage. That split changes the answer a lot, so adjust it to your own on the main electricity comparison.
Should I switch meter type instead of switching supplier?
Sometimes. A smart meter is installed free by ESB Networks and opens up the widest set of tariffs, including flat ones, so upgrading rarely costs you options. A day/night meter only pays if you genuinely shift a large share of usage overnight. Before changing anything, compare what you would pay on every plan across every meter type — the difference between meter types is often smaller than the difference between suppliers.
