Why can't I see my Government levy £170 reduction

I’m trying to understand how the average household energy bill would be reduced by £170 (or£117 according to different sources)? I received a letter today saying that the reduction in my case is £23.90. I’m just curious (putting aside any political discussion) how it was counted? What am I missing?

... is this estimated being counted if I would pay this price 12 months in a row? 
  

No. How it works is explained pretty clearly on these two pages:
https://www.ovoenergy.com/help/article/levy-reduction
https://www.gov.uk/government/news/your-energy-bill-from-april-whats-changing

 

The levies that are being reduced are charged to suppliers per kWh, so the reduction is passed on to you by reducing your price per kWh. This applies to all tariffs. 

I don’t think I’ve seen a mention of a £170 reduction. The budget spoke of ‘an average household saving of £150.’ The figure of £117 you’ve seen is the reduction in the price cap for the April quarter for the typical household; it incorporates the levy reduction and several other changes to both network costs and wholesale prices.

Basically the average use applies to nobody because nobody uses exactly the average. And the average cost or savings doesn't exist because all the Regions are priced differently from the average. You might as well ask what is the length of a piece of string which in your case turns out to be £23.90. If indeed it's right.

… the changes are quoted for the “average customer” 

According to Ofgem, the average (medium) UK household, typically 2-3 people, consumes roughly 2,700 kWh of electricity and 11,500 kWh of gas per year. 
 

The old pedant can’t resist, sorry …

I think you’ll find that Ofgem always refer to the ‘typical’ household or consumer. Their reasoning:

Most consumers use relatively small amounts of energy, while few consume large amounts. The median or second quartile is more representative of the typical “medium” usage. We use the first and third quartiles to represent typical “low” and typical “high” usage respectively. The lower quartile reflects the annual consumption that only 25% of all consumers use less than. The higher quartile reflects the annual consumption that only 25% of all consumers use more than.

[From https://www.ofgem.gov.uk/sites/default/files/2023-05/TDCV%202023%20Decision%20Letter.pdf]

 

Those ‘few’ consuming large amounts would skew the average (the mean) unhelpfully, so the median consumption (the amount that half of households use less than and the other half more than) is reckoned to be a more suitable measure.

Hey ​@costeek 

 

I’m glad to see everyone’s already stopped by with some helpful advice for you already, Firedog linked to a helpful article on the webpage that details more on how the levy will be delivered for each customer sub-section.

 

We do also have a post on the Forum which you can check out below too, but ultimately as Firedog noted, it’ll be applied to unit rates rather than a lump sum payment onto the account. We’ll be contacting customers soon with their new estimated costs, and you’ll be able to see your new rates from 1 April. 

 

 

If you do have any more questions, do let us know.😊

I’m an Agile Octopus user and Greg Jackson has just sent me an email to say that for Agile customers … we will apply the full government discount to your dynamic Agile Octopus unit price …

Now, for those who don’t know, Agile is a dynamic tariff and each half hour settlement period is priced differently. It can go from 99.99p / unit (ouch) to -19p a unit (yes, I get paid to use power). I use about 7,000 kWh a year with my EV and HP etc and that would mean my discount, if applied to every HH price would reduce my bill by about £245.

 

For that to be true then even my negative priced HH slots would be reduced by about 3.5p i.e. -10.0p would become -13.5p. An awful lot of units are priced at zero (it’s the way the market works when there is too much of renewables on the grid) now become -3.5p for me.

 

I’m not saying this is true, I’ve asked on my other forum is that can possibly be true and we may find out after the 1st April if it is true. If it is I’ve definitely come out as a winner in this. (surely not)

 

Peter

… Octopus …  will apply the full government discount to your dynamic Agile Octopus unit price …
  

This is just how it should be done IMO. I don’t know how the costs that have been diverted from energy bills are levied on suppliers, but Ofgem quote them as a price per unit delivered. There is probably a regular estimated payment coupled with a reconciliation, perhaps at year-end. The figures we’ve seen for the amount of the reduction are derived from Ofgem’s current estimates of the size of the levies:

ECO (Energy Company Obligation): £8.91/MWh of electricity supplied, £3.15/MWh of gas
RO (Renewables Obligation): 75% of £33.06/MWh of electricity  

For the electricity supply, then, the cost reduction is 8.91 +  24.80 = £33.71/MWh or 3.37 p/kWh. Add 5% VAT to get the 3.54 p/kWh. For gas, it’s just 0.315 + 5% = 0.33 p/kWh.

The rebate shouldn’t vary at all with the amount you’re paying per kWh - it should depend solely on how many kWh your supplier delivers. It will be interesting to see whether OVO do their sums like this. If you have 4,000,000 customers each using 2700 kWh a year, that’s 10.8 million MWh. Dropping your revenue from one month to the next by £33.71 x 10.8 x 10⁶ = £364 million/12 = £30 million a month while you’re probably still paying off what you took in last (fiscal) year might be painful. 

[E&OE as always!]
