Hi @celyn - thanks for the post. The short answer is that yes, we will still be increasing our prices on 17/12/16. We will of course drop them as soon as we are able to.
Wholesale prices have indeed fallen from the highs of 4 weeks ago - as you correctly say this has been driven by a period of mild / windy weather (which we are experiencing now) and reduced concerns about French nuclear availability in Q1. However, prices are still up this year - the chart below shows the change in the cost of gas and electricity for Q1-17
You’re right that as we have a variable tariff, we don’t enter into long term hedges, and so can follow changes in the wholesale price. As mentioned in our blog here we do however hedge forward for 3 months to insulate our members from month to month spikes in prices. This meant that we were able to hold off for a longer period before raising prices. If prices continue to move lower from here, we will look at reducing our tariff again in the new year.
As you can see from our website, we still have one of the lowest-cost tariffs in the market, renewable or non-renewable (after the price increase) and are committed to continuing to do so.
Hope this helps - we want to be as transparent about our pricing as possible so if you have any other questions or comments, please shout.
