Do off-peak tariffs actually work out cheaper?

Standing charges same for both.

Standard variable
32p per kWh

Off Peak Tariff
00:00-04:00 10p per kWh
04:00-00:00 41p per kWh

Just trying to work out if it’s worth switching

Hi,

off peak is usually 7 hours, thus E7, sometimes 10 hours E10.

Off peak is most advantageous when used with storage heaters and hope to get at least 30/70 day/night split.

It can be but as you have not given us a breakdown of your electric usage in those times slots we have no idea if it will work for you. The break even point on those numbers would be using 30% at the cheap rate.

It depends how much of your electricity use you can get into the low rate times... if 90% of your use is during the peak rate then clearly it will be more expensive than single rate tariff.

Those rates and times do not match any tariff I know, can you say which one it is please?

The answer to your question depends on how much of your use you can shift into that low rate period...

It can be a lot cheaper but as well as the obvious NSH getting much cheaper rates , occupants can cash in by both timering washing machines to be on within the low rate hours as well taking showers within the cheap 7 hours  and  doing their best to use high usage appliances such as irons and tumble dryers in the cheap rate times
If you are prepared to do that then from I ve seen in 20 years looking at Eco 7 meters , average Eco 7 users generally use more than 50 % total  in night rate but you would have to be using NSH to get over 50 % cheap rate units

For us - in a "mostly" electric home (just using gas for cooking) and using 75%+ of our energy overnight, it definitely does - but this is because our heating and hot water runs during the off-peak (14p/unit) hours, we run washing machine & dishwasher overnight, and nearly always shower in that time period as well - although less so in winter as the chances of us being up and showered before 0710hrs on a saturday or sunday are slim at best! If you aren't in that position, then almost certainly the increased unit cost of the peak rate electricity will mean it would be more expensive for you. As exception to that can be if you have an EV - in which case as well as charging it work out which other things can be done in the same timeslot and use that information to inform your calculations.

High mileage EV drivers/those with battery storage, are the other group that fit the profile these days...

Thanks, thats very important nowadays and growing all the time.

We've got Octopus Go,  Very similar to the rates quoted by OP... I charge my PHEV car during off peak hours. We also set the washing machine to come on during the night too and also our 4 month old babies bottle sterilizer is set up for off peak use when possible as-well...

Id say we're probably spending less on Electric now then when we was on 21p per KWH on our last fix.. Cut backs in usage have made a difference too.  We have gone from using around 20KWH per day to around 15/16KWH per day just by switching off stuff  thats normally on standby and using an air fryer instead off elec oven when possible.

Looks more like some type of EV tariff,
