Complex meter: Refused Economy 7?

Hello, we bought our current flat a few months ago and found out that Ovo is our electricity supplier. It is an all electric property, with electric immersion heater for hot water and electric storage heaters. This flat was designed around off peak electricity.

 

There are 2 electricity meters, one so called white meter just for the off-peak circuit (storage heaters plus immersion water heater) and one for everything else, each with a separate MPAN number. The off peak meter turns the off peak circuit on and off, so that water heater and storage heaters only have power at night, it is the RTS type. 

 

When we moved in, Ovo created 2 account numbers, one for each meter and put each on the single rate tariff (without consulting or giving options).

 

This means that we have to pay the standing charge twice and we have to pay expensive rate for hot water and heating. 

I have contacted Ovo multiple times (calls and chat) asking to:

  1. have only one account with one standing charge 
  2. be moved onto some type of off-peak tariff (Economy 7 or something else)

 

I was told that neither is possible. I was told that they cannot merge the two accounts and that they cannot put me on Economy 7, because I have the two meter set up (complex meter).

Also, I wasn’t offered migrating to a 5-port smart meter with Economy 7 as a solution - I only came across it on this forum. 

I don’t understand this. Why can’t they offer some kind of peak / off-peak tariff to me?

 

I know about the shut down of RTS signal next year and the push to smart meters. However, switching to a smart meter is not useful for us if they refuse to change our tariff.

Also, I think we should only be paying one standing charge, as these two MPANs are associated (it is one household). 

Can you please advise? What are our options?

Check out our dedicated RTS FAQs page for more information.

You should hear shortly from OVO about arrangements for replacing your meters with a new smart meter, if you haven’t heard already. Until then, I’m afraid you’re stuck with the current tariff: OVO doesn’t have any that can apply one high rate to one of the supplies and a low one to the other, and I don’t think there’s any other supplier that could do this.

 

No-one with a complex metering arrangement (what the industry calls a Restricted Meter Infrastructure, RMI) should have to pay two standing charges if the tariff is single-rate. I would think that the artifice of two separate supplies is immaterial in this respect: you are being penalized in the way that this condition (SLC 22G) is intended to avoid. You should submit a complaint in writing about this, expecting to have any extra standing charges you may have paid refunded. Other customers who went all the way with complaints like this were also given compensation for OVO’s failure to comply with their licence conditions. Read about Ofgem’s decision on this sort of situation.

I noticed you wrote that you’d opted for Economy 10 when your smart meter is eventually installed. I said I’d try and come up with some comparative figures for you; I did, but then forgot to post them. I’ve rather assumed that you reside in Auld Reekie …

The costs depend very largely on the usage pattern. If there’s a chance of running greedy appliances other than heaters (e.g. electric shower, tumble dryer, cooker, iron ...) only during offpeak periods, costs would be minimized. It’s not unusual for an electrically-heated household to use 75% of the total energy consumed during offpeak hours. This table shows some comparative figures to illustrate the effect of changing the proportion of offpeak usage:
  

 

If this is all too confusing, I’ll crawl back under my rock and leave you in peace … 🐢

HI ​@EdinburghFan - I’m a customer in a similar situation to you, (also an Edinburgh resident with Comfort Plus Control) except I’m with Scottish Power. I’m aware this is an Ovo board but I’m desperate for some help! 

Scottish Power have said to us that they will change us to White Meter 1 tariff (obvs they are not Ovo), but that’s not suitable for our set up which is the same as yours - Comfort Plus Control. I have tried to get them to engage with the fact they can’t just switch us to that tariff as it won’t work with our meter set up as we have two separate meters with two separate circuits with two separate sets of wiring. Even if it were technically possible - we don’t have timed heaters so we can’t use off peak heating at all. They’ve booked us in to get a smart meter on 13 May and nothing, NOTHING is getting them to listen to me.

Could you let me know what Ovo are doing for you, so when someone finally calls me back (they’ve missed 5 scheduled callbacks as this is too complicated for any customer service agent to deal with, so they’ve just not bothered,) I can tell them what a responsible energy company is actually doing? Please message privately if that’s best.

To Ovo - I’m obvs not expecting you to advise on anything but please please don’t delete this message as I am at my wits end with trying to solve this. I’ve shed more than a few tears! I’ve even contacted my MP and that’s made no difference!

Hi ​@CookieCooke,

This forum is open to everybody not just customers of OVO.

Obviously if you are not an OVO customer some of the staff and volunter's internal “superpowers”  can't  be used - but help and advice is always offered.

TBH I myself know nothing about these old tariffs - Total Heat Total Control, Comfort Plus, - but others here do know them and will help as much as they can.

I said, Hey - Watts going on.
