Economy 10 - EDF

stephem

EDF have almost doubled their off peak rates for Economy 10 from 1st Jan from 8.57p per kwh to 16.67p. Admittedly it seems that 8.57p was a very low price, but this is still a massive increase. As we have storage heaters the vast majority of our electricity use during winter is off-peak, which means that our annual bill is estimated to increase by about 50%! Is anyone else in the same situation? Are there any other suppliers that offer Economy 10 with lower off-peak rates? Any other suggestions / advice, apart from ripping out our old storage heaters and replacing with a different system?

Most people who are on E7/E10 with EDF will be in the same situation, EDF had incredibly low night rates in some regions, they have raised them, but they are now largely in line with their competitors, although still 20-30% lower in some regions. You might get better rates on E7 than on E10, but apart from that, just shop around between different suppliers to see who offers the best split of peak/off-peak rates based on your usage.

Plenty of threads on this including one a few hours before yours.

I think you must be mistaken unless you have virtually no peak use.
I just checked my use, which is 79% off peak and my cost would be going up from £2724.12 p.a. to £3,489.71 p.a. on that basis (I went for a fix to lock in the 8p rate).      At 79%  off peak, it is around a 25% increase in cost.

 Is anyone else in the same situation? 

Those with EDF Eastern who didn't fix when the rates were extraordinarily low.

 Are there any other suppliers that offer Economy 10 with lower off-peak rates? 

A few but not many and not by much.  EDF have reverted to typical range.  They were a dirt cheap outlier before.

My EOn E10 off peak rate is now 19.8p from 18p Oct to Dec, peak lower at c36p.

Edf rate c16.3 - but the peak rate c5p more at c41p vs c36p.

A win in winter a losing price split for me in summer when I last thought about switching.

(Given issues some with more standard e7 metering have had with edf billing, peak off peak meter vs tariff rate mismatches etc etc - decided at the time the small savings not worth the risk)

AFAIK very few suppliers are taking on new E10 customers.

There was a rumour in 1 or 2 posts - edf could be.

I was told years ago by EOn meter fitter E10 was only available to legacy customers - I was on EOn equivalent of dual meter RTS EMEB Heatwise before EOn now EOnNext E10. 

A tariff they have failed to support on newer smart meter upgrade according to one poster here who was moved to e7 - and despite takinb to ombudsman - nog sure ever got e10 restored.

I did do a quick search before posting, but didn't find anything, possibly because most previous threads relate to E7. This site is not the easiest to navigate.

We have very little peak use (bear in mind with E10 we get 5 hours off peak during the afternoon / evening). Quote from EDF's letter in Dec: "You currently spend £1,015.43. New spend from 1 January 2024 £1,501.14. Change in spend (over the next 12 months) £485.71." That's an increase of 47.83%.

I didn't know at the time that the rates were extraordinarily low, neither was I aware that you could fix E10 rates. Only remember standard variable rate being available for E10.

Scot_39

Yes - EOn Next AFAIK are the same - they offer nothing other than a variable tariff on E10 (as far as I am aware - havent asked for a while - any options offered in past bills have been SR or E7 based).

E10 is very much a legacy tariff - the vast majority of multi-rate meters are E7 - but there are many other legacy multirate tariffs -

It tracks the multirate cap - but not at around the nominal 42% split for E7 (i.e. it includes allowance for the extra 3 hours).  You pay for those extra 3 hours - in my case 5 hours of daytime off peak split 3 early afternoon and 2 late evening

I suspect I will need to upgrade my 3 old basic NSH if (or rather I suspect when - possibly with smets1 meter replacement looming) I lose E10. As my neighbours who were attracted by a cheap fix on switch to E7 had to c2019.  They fitted 4 new Quantums.

E10 is now considered a legacy tariff, supplies are no longer required to support it and I’ve not heard of any who are still open to new E10 customers. Realistically, you best options may well be to either stick with whatever rates they’re offering or to look into E7 to see if that could achieve lower overall costs.

Welcome to the forum.

You could consider E7 but you probably have old storage heaters that aren't High Heat Retention and would be cool by the evening.

If you own your property and plan to stay for some time it might be worthwhile upgrading to Dimplex Quantums on E7.  Not cheap to buy but lower running costs and more attractive to potential buyers.

We are with EDF and on economy 10 for heating and hot water since the change to smart meter in June ( which they said we had to do and would not effect our economy 10) out bills having rocketed!!  The system cuts in during the day as it used to but gets charged at the day rate. We have constantly been contacting them via phone email WhatsApp and still have not been given a practical response other than changing to simply fixed economy 10 at 41.47p peak and 14.12 off peak with a daily charge of 59.97p which seems high for peak rate and they cannot or will not say the off peak timings! My bill is growing and I really don’t know where to go next! I tried to go on a comparison site but they have said unable to access my meter details! Any one else suffering with this - have any suggestions??

Welcome back to the forum after 14 years @brigettejb !

That sounds !!!!!! though your ALCS schedule has not been aligned with your tariff schedule.

@Rosie1001 had a similar problem with EDF after she got her smart meter. She fixed it eventually (see this very long thread) but in the end she switched to Octopus and their Snug tariff.

Sadly, that sounds about right for E10 these days. You'd probably get lower prices on E7 but then you only have 7 hours of cheap electricity a day, all overnight.

If you do choose that, you should be able to work out the offpeak timings by staying up late and looking at your meter.

E10 is an obsolete tariff offered by few suppliers. The best off-peak heating deals are smart tariffs like Snug Octopus, as mentioned previously.

@brigettejb

Changing from one e10 tariff to another will only fix your peak rate chargjng for your I presume 2 daily (e10 often split 5 grs overnight, 3 grs afternoon and 2 evening - fir me thats 0000 to 0500, 1300 to 1600 and 2000 to 2200) if edf set your meter properly to do so.

As it sounds like you may have mismatched tariff  timings and smart meter load control (alcs) timings.

Folk have reported issues with getting e10 rather than vanilla e7 (overnight 7 hrs) at edf since June 1st.

You could ask edf to send matching alcs calander to your e10 tariff times to your meter - but they may or nay not agree.

You should also I suspect be looking for compensation for the error of billing you at thr higher rate - which might need escalating to complaing then energy ombudsman.  If thry set your meter to run hw and heating on e10 - they should have sent matching tariff times - to charge it properly at off peak rates for the 10 hrs. 

It sounds like you might well be in the position another forumite Rosie1001 ended up in April just weeks after a smart meter on e10 upgrade.

Buf it is useful to know they are offering a new e10 tariff if your heating really still need it.

But e10 is always a little more expensive cf the more open e7 (edf used to match off peak rates with e7  eon used to match peak rates so charge a higher off peak - so not as good if a high heat user.)

So before you continue - and based on say @Rosie1001 threads in Mar and Jun it could be weeks of contact - do you still need e10 ?

That will really depend on your heater type(s) and if say NSH - their age / generation - so can you post info  on heating ?
If you have NSH how are wired - single restricted, live and restricted or single live 24/7 ?

Old nsh for instance might struggle to last all day with a stable / desirable room temperature profile - hotter especially - on coldest days  - but more modern ones - like lot 20 or hhr - could be fine on cheaper e7 or say another tariff option you might not have heard of - Octopus snug.

Or if your wiling to switch supplier - and you have meter switched restricted feeds to nsh - and if it communicates readings reliably to edf then it should to other suppliers - so you could consider follow @Rosie1001 who gave up on her edf e10/e7 tariff and meter fight and switched to Octopus and then onto their Snug tariff. 

https://octopus.energy/blog/introducing-snug-octopus-our-smart-tariff-for-storage-heaters/

9p night rate - 6 hrs overnight core - but often give 1+ hrs more at 9p rate dynamicalky - but also with + 1 hr afternoon to top up heaters.- and a lower day rate (30.17p quoted today in em).  But it needs communicating  smets2 meter and meter controlled NSH.


If you want to stick with e10 - iirc Ovo now quote others.
