Cheapest Economy 10 prices – May’17

LATEST ECONOMY 10 PRICES:  It’s been a busy few weeks here at, rolling out the new community-powered approach for the website – it’s great to see so many people getting involved.  But it also highlights how little the big energy companies are doing to support these customers.  E10 prices still aren’t available on switching sites so we’ll continue to publish as much information as possible in the meantime.  Read on to find out who provides the cheapest Economy 10 tariffs…

  • There are six Suppliers who fully support E10.  They will install a new E10 meter if you don’t already have one, fix a faulty E10 meter, and generally provide a better understanding of the whole process.
  • There are a further ten Suppliers who partially support E10.  They usually apply their E7 prices to your E10 meter (that’s ok).  They don’t usually fit new E10 meters if you don’t already have one, and may not be able to fit a like-for-like replacement if your E10 meter has a fault.  Quality of E10 information can be variable with some of these suppliers so you may need to be patient.
  • To complicate matters, each Supplier sets different prices in each of the UK’s 14 Regions.  The cheapest supplier in one region may not be the cheapest supplier in other regions.

From the latest user survey, we have a complete picture of all suppliers in Region 17 (North Scotland).  Even if this isn’t your region, it should give you an indication of who the cheapest and most expensive options are likely to be:


There’s a lot in this graph so let me explain:

  • Bars show the price of peak (orange) and off-peak (grey) electricity, in pence per kWh, from each supplier.
  • Darker bars show suppliers who fully support E10, with a dot next to their name.
  • Blue values are an average price, assuming 80% of your usage is off-peak.
  • Red values at the bottom are the standing charge, in £ per annum.  Any paperless billing discounts are already deducted.  This assumes payment by monthly direct debit.
  • Our Power only supplies in Scotland.  iSupply supplies everywhere except North Scotland.  E.On will only quote for existing customers.
  • Scottish Power, Green Star Energy, and Octopus Energy – whilst they technically support E10 on E7 rates, feedback from people trying to get a quote or switch is so bad I can’t honestly say they support E10 in practice.

You can see that two of the large players, SSE and EDF are a whopping 50% more expensive than the cheapest in this region.  Switching your electricity supplier could save you hundreds of pounds each year.  Links to all the suppliers are on the website here.

I’ve written a separate post about EDF’s 20-25% price hike, and how their prices vary regionally.  And for more background info on E10 pricing click here.

A full list of suppliers and their website links here.

In the meantime if you get any new supplier quotes, please add them to the community using this web form and I’ll periodically summarise and post on the blog.

Hope this helps!

Cheers, Mark

  1. Hi Mark. Always look for your site when renewing. Thanks for making things easier to understand. I am now getting different answers re off peak times. I know what they are however , having just asked the they alter when clocks go back .? I was told the times we are operating on now ( winter ) are the correct times for off peak and they actually move forward an hour in summer . I am on 12 am to 5 am , 1 pm to 4pm and 8 pm to 10 pm. So they are saying these off peak times move forward an hour in Summer time. Do you know if this is correct .?

    Many thanks

    • Hi Andy, I hope you don’t mind me replying to your post though it is addressed to Mark. It’s difficult to say without knowing your specific meter model, some meters remain on GMT all the time, however some meters do change the time automatically when BST/GMT ends so the off peak times remain the same throughout the year(this is the case for myself in the North of Scotland), unless your meter has the time showing on it the only way of knowing is the old fashioned way of checking on your meter once BST comes around and look at your meter when it is due to switch between rate 1/2 and see if it moves rate at GMT still, I hope that makes sense. Sorry I couldn’t give you a more simple yes/no reply. I hope this has helped but if you have any more questions feel free to ask.
