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.

It moves with the seasons to keep in-sync with the meter.

So the off-peak times are, for example, 04.30 to 07.30 (winter/GMT) and 05.30 to 08.30 (summer/BST).

I’ve just looked at other past questions/answers elsewhere on the forum about this topic.

The list of times for MPAN 17 that I found on the forum  (from OVO ?) is confusing - or should I say misleading?  At least it’s not just me that’s been confused!

It’s all down to what meter is installed. Some manufacturers do shift between BST and GMT, others don’t.

Hey ​@Sandy42 

Welcome to the OVO online community 😊 I can see Blastoise has already given some helpful advice here. I just wanted to add the following:

 


 

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.

Yes, I found that list of times earlier. That’s where the confusion started for MPAN17 started . It should say 05.30-08.30 BST for MPAN17 to avoid confusion (I think!!).

Isn’t that what it does say - The very bottom line there is BST in MP17 (unless you have an ‘old style, not-Smart’ meter).

Sorry - you are correct. Think I initially looked at a different table. All well now- I must learn to read properly!
