SMETS2 (Landis+Gyr E470) Economy 7 to single rate - webchat insisting on engineer visit and £432

Hi all, hoping someone here can cut through this, as multiple webchats have gone nowhere and I keep getting the same incorrect information.
What I want: to come off Economy 7 completely and onto a single rate tariff, with my MPAN profile class moved from 02 to 01. I do not want a tariff that keeps two registers priced identically, as I understand that leaves the profile class at 02 and risks reverting to multi-rate billing on a future supplier switch. I have already checked and single rate works out cheaper for me.
What webchat keeps telling me:
    1.    An engineer has to physically swap my meter from two rate to one rate.
    2.    This will cost me £432.
Both look plainly wrong, and here is why:
    •    My meter is a Landis+Gyr E470 (Type 5424), under a Toshiba SMETS2 comms hub. It is a single phase supply: the nameplate reads 230V 50Hz, 1-20(100)A.
    •    The E470 is SMETS2 and, per Landis+Gyr’s own spec, supports up to 48 time-of-use rates and is configurable in-field. Single rate vs Economy 7 is a configuration, not hardware.
    •    Right now the display is showing ‘Rate 01 Act Imp’ - so the meter is already doing time-of-use in software across multiple registers. Moving to single rate just flattens that to one register via a remote SMETS command. No meter exchange, no engineer.
    •    The meter is communicating fine (WAN/MESH lit, readings and half-hourly data show in my account).
    •    On the £432: OVO’s published charges list at ovoenergy.com/energy-charge-list has no fee for a two-rate to single-rate change. The only £432 entries on that page are all three-phase (accuracy testing, meter repositioning, installation). My supply is single phase, so none of them apply.
Can someone please:
    •    Confirm this is a remote reconfiguration on the E470 with no engineer visit and no charge.
    •    Advise the correct way to get the profile class changed to 01 alongside the tariff, so it sticks.
    •    Flag it to someone who can action it, as the front line clearly can’t.
Happy to share meter serial, MPAN, MTC and SSC by DM if a staff member can pick this up. Thanks.

Hi ​@Gclarkey ,

Bit of a snaggy one here! The best option right now is to accept having both registers set to the same rate remotely which OVO DOES support. If you ever choose to leave OVO, it is possible to have the Profile Class updated so that it shows flat rate to other suppliers.

It’s a billing system limitation more than anything else. Don’t pay the £432 unless you really want to.

Thanks Blastoise, that's really helpful and has saved me a pointless £432.

Happy to go with both registers set to the same rate, since the cost outcome is identical to a true single rate and it can be done remotely with no fee. That works for me.

One thing I want to get straight before I sort it: can the Profile Class be moved from 02 to 01 now while I'm still with OVO, or does that genuinely have to wait until I leave? I just want to be sure I won't get dropped back into multi-rate billing if I switch supplier down the line, so if there's anything I should note on the account now to make a future switch clean, I'd rather do it up front.

Also, what's the best way to actually get the same-rate tariff applied? Is that something a staff member here can flag to be actioned, or do I need to go back through webchat and quote this thread? Every chat so far has just tried to sell me the meter exchange, so a pointer to the right route would be great.

If memory serves… That can be explored at anytime. But it’s a back office job so it does take time.

Nothing can be done from here, unfortunately. Going back through webchat (or call them) and quoting this thread would be the option.

I do not want a tariff that keeps two registers priced identically, …
  

This was written back in 2019, but so far as I’m aware, it still applies:

Can I switch from an Economy 7 plan to a single rate plan?

We currently can’t change smart meters from a single rate to Economy 7, or the other way around. We are working on this and will update you on our progress in the Forum.

However, we can change an Economy 7 tariff to a single rate tariff. This means we will still take both readings but charge you a flat rate for the total usage. This change usually helps customers who have removed their storage heaters or immersion heaters.

If you have an Economy 7 tariff but don’t use storage heaters or an immersion heater, our Support Team can check if switching to a single rate plan would be better for you.

Can I change from a single rate plan to an Economy 7 plan?
Unfortunately, we're unable to make this change due to some technical limitations.
 

  


So the single-rate E7 solution is all that’s available at the moment without a meter exchange. A new standard meter would be in PC01.

If you were to opt for the cheap, quick and easy (but irreversible) change to single-rate billing, the meter would stay in PC02. This might mean that you would have to make contact with any new supplier in order to switch as opposed to being able to do it automatically online.

The whole MPAN system is in a state of flux at the moment and will continue to be so until next Spring at least, as the electricity supply industry moves in to Market-wide Half-Hourly Settlement (MHHS). I would expect any other change to an MPAN to take longer than usual, possibly much longer. If you’re able to hold off trying to have your PC changed, it might be a good idea to do so.

Morning ​@Gclarkey and welcome to the OVO Forum!

 

I can see you’ve had correct advice from some of our members already (thanks everyone), so the only thing I’ll add is that, when you speak to our Support Team, tell them you’d like to move onto a ‘P2 to P1 tariff’.

 

Important: Get Support to calculate your annual usage, and compare it against the P2 (eco 7) rates and P1 (single rate) rates. In the past I have done many of these myself, and very often would find that economy 7 was still working out ever so slightly cheaper. It all depends on how the tariff rates are looking at the time, but my main advice is not to jump straight into a single rate plan without these calculations being done first.

 

Let us know how you get on.

… economy 7 was still working out ever so slightly cheaper.
 

There is a simple calculation that can tell you whether this will apply:

  1. Find the consumption figures for peak and offpeak usage, e.g. by subtracting last year’s readings from this years. Find the offpeak proportion of the total.
  2. On OVO’s Our prices page, click Electricity and then use the filters to select:
    ■   Meter type: Multi rate
    ■   Payment method: Direct debit
  3. Scroll down to find the tariff you’re interested in, e.g. Simpler energy with the same rate for peak, offpeak and anytime. Note the Unit rate - call it A.
  4. Scroll down to find the Economy 7 tariff you’re interested in, e.g. Simpler energy again. Note the Unit rate for both peak and offpeak and call them B and C.   
  5. Work out (B - A) / (B - C). This will be a value between 0 and 1, probably between 0.3 and 0.4.

The value at (5) is the break-even point. If the number from (1) is lower, Economy 7 will be more expensive than single rate. If it’s higher, Economy 7 is less expensive. Any difference in standing charge will not usually be significant.

Most households use more electricity in winter, so it may be interesting to work out the proportion at (1) separately for April - September and October - March as well as for the whole year.
 


For my region, A = 23.90, B = 25.88 and C = 17.67. 
25.88 - 23.90 = 1.98
25.88 - 17.67 = 8.21
1.98/8.21 = 0.24

The differences in meter readings over the past year were:
Peak: 929
Offpeak: 308
Total: 1237
308/1237 = 0.25

… so really I shouldn’t be on the single-rate tariff. However, the difference in fuel cost is just 52p for the whole year, while the difference in standing charge is £2.03 with Economy 7 winning.
