Hey @Turnip 

 

I’d be in agreement with our volunteers on this one from everything you’ve explained.

 

My question is and cannot get ovo to understand is if telly switched off it does not register a usage, but my econ 7 switched off at wall plus at master switch registering nearly ten quid for no reason

 

The meters don’t have on/off buttons and continuously record your usage - they cannot be switched off. With E7, your meter works on 2 timeframes - a day and a night rate (times vary per area), when the day rate stops clocking, the night rate kicks in. No matter if you’ve switched off the immersion or storage heaters, you can’t switch of the actual meter.

 

1 unit overnight is not an unusual or unreasonable thing to see, for things like the fridge which most people leave on all night, 365 days a year.

 

I understand you believe it’s not recording this usage as you’ve said everything is off, but even if you’ve switched the storage or immersion off, the meter will still clock any other usage during this time on your night rate - so if the fridge is on, the meter will clock that usage. Similarly, if you were to cook a meal or make a cup of tea during the off-peak time, this usage would be clocked on the off-peak rate, as that would be the only register clocking - the meter never stops recording your usage. They’re not going to not charge you for usage overnight - hence why the meters can’t be switched off.

 

Unless you’ve switched the actual electric off at the mains, and you therefore don’t even have the fridge running or any access to power, so therefore no usage could even occur, then that would be the only case we could imagine seeing absolutely 0.0kWh being used.

Otherwise we’d expect there to be at least minimal usage throughout the night rate. If it’s recording less usage than you think, and maybe more on the day rate than expected, then it may be that the time-switch is faulty, in that case, the meter would need to be replaced. See below a similar thread where the time-switch was the faulty for no usage recording overnight:

 

 

Our volunteers have tried their best to help and to understand the circumstances, and have given you all of the information that we would and then some, as they’ve even got experience with their own set ups to help back all of this up. 

 

  

If this is so why does my econ 7 meter not charge for the usage of tosster and kettle when im up at 5 in morn? It still only registers 1 unit.

Do the sums:

  • Kettle 3kW x 3 mins > 9 kW-minutes  
  • Toaster ditto > 9 kW-minutes
  • Total 18 kW-minutes ÷ 60 = 0.3 kWh

If your fridge, freezer etc. are consuming say 0.5 kWh overnight, this will register as 1 unit. Add together: 0.5 + 0.3 = 0.8 kWh. Still only registering as 1 unit.

 

 

I’ve linked below to a helpful topic on Economy 7 if you wish to take a read: 

 

 

If you’re still debating this matter then you can speak with the Support Team, but as Blastoise has said, the likelihood of the meter being faulty is slim, especially based on the information you’ve provided over the forum. It may be worth getting the smart meter installed so that you can view your usage in more detail and this may show you what’s using energy overnight. 

 

I’ve linked to another topic on situations where the meter is clocking too fast, this may help you judge whether you want to proceed with testing or not if you were considering going ahead with it.

I fully understand it, not least having written guides about Economy 7 myself.

Is an Economy 7 plan right for me?

 

The main advantage of an Economy 7 plan is a much cheaper unit rate for any electricity used during your off-peak times. This can often be several pence cheaper per kWh than the standard unit rate. It’s worth bearing in mind that to compensate for this cheaper off-peak rate, an Economy 7 plan charges a more expensive daytime or peak unit rate than the standard anytime rate. Therefore in order for this type of plan to be beneficial you’d need to use a certain percentage of your usage during these off-peak hours. This percentage will vary depending on the tariff prices available at the time.  

 

Are you sure you’re on Economy 7 and not something else?

I get the feeling you’re on a different setup. Please provide photos of your meters.

Having looked at the meter types out there, I think you’re actually on an SSE Superdeal Meter:

Superdeal

Like Flexiheat, Superdeal is exclusive to customers in certain parts of southern England. It also has one meter with three rates:

  • One rate records all the electricity you use during the day
  • Another records all of the electricity you use during the night period
  • The third measures all the electricity you use during the seven hours of cheaper-rate electricity for stored heat and hot water

Superdeal works by storing up heat and hot water using the lowest possible rate of electricity. It works best with storage heating, so it isn't usually suitable for homes with other forms of heating.

Alternatively, you might be on an SSE Flexiheat Meter:

Flexiheat

Our Flexiheat tariff is exclusive to customers that live in certain parts of southern England. It offers you seven hours of cheaper, off-peak electricity for your stored heat and hot water. Not only that, but you also get a cheaper rate for all the electricity use in the evenings and at weekends, as well as a cheaper rate all day between 24 December and 1 January.

You get one meter which has three rates:

  • One rate records the electricity you use during the day
  • Another for electricity used in the evening and at weekends (and the Christmas period)
  • The third records all the electricity you use during the seven hours of stored heat rate electricity, for stored heat and hot water.

Possitive   the unit comes on a say 12 to 7  can vary anything conected to this meter will register a usage at reduced rate, any thing on normal high rate will still be on full rate, if i was being charged a unit per night for that, i would not complain as when using kettle and toaster would be halfprice before 7 in the morning.

Perhaps you have one of the meters with the extra terminal to switch in at off peak @Turnip ? A photo would be useful to see. Then it would be a matter of identifying the circuits that feeds just in case there’s anything else linked in. 
If you’re seeing something on your in home display, that could be a different solution

In that case, please post photos of your meter(s). It’ll be easier for us to figure this out once we’ve seen those. Ideally, please post as many photos as possible from different angles and include a few that show the wiring near the meter

Seems similar to them so if switched off they should not register unless being used

As well as posting some photos to help the experts figure out your setup, could you also explain:

  • where you see economy 7 meter register 1 unit per night;
  • where you see  my econ 7 switched off at wall plus at master switch registering nearly ten quid; 
    1 unit costs about 35p, so it would take about 30 units to clock up £10. 
  • If you’re looking at an In-House Display, you will most probably see the standing charge for the meter - about 50p - added each night. Do you see this spike?

The clearer the information you give, the greater the chances that someone will be able to help.

 

PS I too have an E7 setup with storage heaters and an immersion heater for hot water. There are dozens of different ways of wiring these up, which is why the experts here are asking for photos.
