I've worked out a few calculations using a spreadsheet to work out what will happen if the energy price guarantee unit rate (per kWh) reductions (17p and 4.2p for E and G respectively) are applied in full to fixed tariffs that people may be on. I've restricted this to the Online Next v ? Direct Debit Tariffs and compared them to the Next Flex Tariff (the SVT) that we should see from October 1st. I've used my own anticipated yearly usage of 2500 kWh (E) and 6800 kWh (G), kept the same standing charges and unit rates for my region (Northern). Just the total figures I've calculated plus an indication of the unit rates (E/G) after any reductions, using these assumptions:
SVT i.e Next Flex from October 1st (34p/10.3p) = £1828.27 yeary total
Fixed Online v 17 from October 1st (32.96p/8.55p) = £1583.92 yearly total
Fixed Online v 18 from October 1st (34.83p/9.01p) = £1762.05 yearly total
Fixed Online v 19 from October 1st (42.15p/10.77p) = £2063.98 yearly total
Fixed Online v 20 from October 1st (49.34p/12.51p) = £2362.05 yearly total
The one thing anybody should take from this is that if you are currently on v19 (or later), you should drop onto the Next Flex tariff immediately. If you have set it up for a later date then cancel it and drop onto the SVT on October 1st or possibly earlier depending on your current tariff.
If you are currently on v17 (or lower) don't move off it until the end date, unless other information resolves the 'floor' issue.
If on v18 (or about to move onto it) the decision is marginal but, it should prove slightly cheaper than SVT so stay on it/ don't cancel.
Hope this has helped those deliberating on staying on their fixes or moving to the SVT (Next Flex) tariff.
Of course things can change so take this information with a huge pinch of salt.
****Edit: Looks like there is news on fixes such as this meaning there appears to be information coming from M Lewis indicating that there is indeed a 'floor' such that unit rates would not be allowed to go lower than the announced SVT if the EPG reductions are applied to your current fixed tariff***
If this is the case, then only fixes currently lower than the announced SVT rates for 1st October would be worthwhile staying on. Everything else means that you are better off going to the SVT on October 1st (or immediately if your current fix is higher than the current SVT)
It appears SVT tariff charges for both standing charge & unit rate has increased significantly over the past day or so - was given the following rates by Eon earlier today.
All prices in pence & inc VAT.
E.on Next Flex tariff(s?) 15/11
FLEXDIRECTDEBIT-21-07-20
Std Chg kWh
E: 43.26 51.32
G: 28.48 14.75
FLEXRECIPTOFBILLS-21-07-20
Std Chg kWh
E: 49.14 54.06
G: 33.54 15.54
[Not sure what the second tariff is - maybe price if not paid by direct debit? - was sent both at the same time as but only Next Flex was referred to]
For Reference SVT rates 11/9
FLEXDIRECTDEBIT-21-07-20
Std Chg kWh
E: 42.24 28.02
G: 27.22 7.34
These tariff rates *do not* take into account the 1 Oct price cap increase, they will still go up.
When asked about the effect of the EPG was told ALL tariffs will be revised in line with Gov't announcement of 8 Sept.
Was just wondering what your thoughts are regarding changing from fixes to the SVT now given these price increases 2+ weeks before to the price cap increase is due to come into effect.
