Economy 10 current and new tariffs

Tokamak4D

I'm hoping someone will have had some experience or advice about this. 

I'm with OVO Energy and have Simpler Energy - Economy 10because I have a Wet Electric heating system.

There are a number of issues with this system and tariff, but the immediate issue is with unit pricing. 

My confusion is around different information being given by my supplier. 

Within the OVO Android App, I have 2 sets of numbers for the current and changing unit prices,
however, I have received an email today from OVO telling me current and changing unit prices, and these do not match (the app account is signed up via the same email address for the supplier account).

App info from my last bill.                       App info 
Current costs                                          New costs
Off-peak    kWh     -16.79p                     Off-peak    kWh    - 17.63p
Peak         kWh     - 22.20p                     Peak         kWh    - 23.31p
Standing Charge  - 61.42p                     Standing Charge  - 64.49p


And the cost info from the OVO email

Current Costs                                         New Costs
Off-peak    kWh     - 17.63p                    Off-peak    kWh    - 20.46p
Peak         kWh     -  23.31p                    Peak         kWh    - 25.11p                  
Standing Charge  -  65.15p                    Standing Charge  - 65.15p 

Which numbers do I trust? The smaller increase will be hard to bear, however if the increases are 
actually, the larger numbers from the email, then I'm in real trouble. 

Has anyone else experienced this? Any advice gratefully received.

On the email are they the new rates from October 1st? Looks very odd..

im on e10 with EDF, their rates from October as comparison are S/C 51.26p per day, 30.95p day rate, 14.16p night and heat rate. In the eastern region.

you can see their rates in other regions on here (they use the E7 rates for E10)

VAT.

In your 'app info' figures, the ones on the left are ex VAT, the ones on the right include VAT. The current/new costs figures include VAT.

There's quite a big increase in the offpeak rate (16%) but a lower one on the peak rate (8%). Did you perhaps mistranscribe the standing charge? The 'current' figure looks as if it should be the same as the one in your top-right table. The increase is insignificant (£2.40 over a whole year)

The rule is that for E7 to be economical, your ratio of offpeak to total usage over the year has to be more than 

• [Peak rate - Single rate] / [Peak rate - Offpeak rate]

If you told us your postcode area, the name of your plan and the method of payment, we could look up the actual figures for peak, offpeak and single-rate. Meanwhile, you could work out your peak and offpeak usage for the past year by comparing the meter readings from the latest bill to the ones from the same bill a year ago. 

I don't know whether OVO are behind the field at the moment, but I suspect that the 1 October rates haven't yet made it to every page where their rates are shown. Sometime next week, perhaps.
