Hey @awills61, 

 

I found another thread which might be helpful in giving the answers you’re looking for:

 

The E10 times are listed as:

 

Economy 10

 

Economy 10 provides 10 hours of off-peak electricity for everything in the home and can be suitable for a number of electric heating systems, including wet electric central heating and storage heaters. Storage heaters will automatically store at the off-peak times on the lower rate.

 

Electric immersion water heaters will also usually heat automatically during the off-peak hours and you may want to install an external timer to regulate when and for how long the water heats.  The off-peak hours offered with an Economy 10 plan add up to 10 hours during each 24-hour period – which is why this plan is known as Economy 10. 

 

(MPAN) 10,11,12, 14,15,16,19,20, 21, 22, 23

(Traditional, Pay as you go & Smart)

12.00am - 5.00am 1.00pm - 4.00pm 8.00pm - 10.00pm (GMT)

1.00am - 6.00am 2.00pm - 5.00pm 9.00pm - 11.00pm (BST)

 

18 & 13

(Traditional)

4:30am - 7:30am 1:00pm - 4:00pm 8:30pm - 12:30am

 

(Paygo & Smart)

4:30am - 7:30am 1:00pm - 4:00pm 8:30pm - 12:30am (GMT)

5:30am - 8:30am 2:00pm - 5:00pm 9:30pm - 01:30am (BST)

 

17

(Traditional)

4:30am - 7:30am 1:30pm - 4:30pm 8:30pm - 12:30am

 

(Pay as you go and Smart)

4:30am - 7:30am 1:30pm - 4:30pm 8:30pm - 12:30am (GMT)

5:30am - 8:30am 2:30pm - 5:30pm 9:30pm - 01:30am (BST)

Hi @awills61 ,

Generally it’ll be one hour later in Winter. Smart Meters run on GMT 0 all year round and don’t change their clocks for British Summer Time.

    That’s what I thought but this page on the OVO site seems to say that in Scotland (MPAN 17) the times  are the same for GMT and BST unless you have a PAYG meter. So I was interested if someone who had just had a new meter fitted on E10 could verify this.

    It’s only Trad Prepay that do that - Smart Meters remain on GMT all the time.

    Nope, they are correct. Just needs a note added for this purpose, easy fix.

    @Blastoise186 I think reading your notes here is confusing .. you said 

    It’s only Trad Prepay that do that - Smart Meters remain on GMT all the time.

    but then @awills61 mentions this page 

    So the times don’t change for GMT/BST then

     

    and then you say .. 

    They do for Traditional Meters.

     

    From what I understand, apparent times do change for smart meters depending on GMT or BST because they don’t change their base time

    So what times would apply to me then when I get my smart meter?

    Generally it’ll be one hour later in Winter. 

     

    Errr … are you sure about that? My E7 offpeak hours have just changed from 01-08 to 00-07 for the winter. I’d call that an hour earlier.

    Plan timings are specified (really confusingly in JS) as either GMT:!0 or GMT:!1. My own are shown as GMT:!0, meaning (perhaps) not false. So they stay on GMT all year round and shift with the kitchen clock twice a year.

    I see that some E10 times are shown as GMT:!1, meaning (again, perhaps) not true. I’m still waiting for one of the luckier Northern Scottish THTC>E10 migrants to tell us what (if anything) happened yesterday. Perhaps they’ve been put on the plan that has (GMT:!0) offpeak times “All days 0000-0500, 1300-1600, 2000-2200”, shifting with BST. I’ll be happy to be proved wrong!

     

    Just a note about the page referred to above: as usual with OVO help articles, it’s not dated, so we’ve no idea whether it’s current or not. @Emmanuelle_OVO  may have consulted the horse’s mouth to find these timings.
