Economy 7 hours

E7 meters can also go out of sync on their timer.   Currently, our E7 hours are 4.30am to 1.30pm.  (rounded to nearest half hour).  It is wrong for our region but the meter clock loses the time periodically.  Ours is not a switched circuit but timer.  
Each month I give the meter readings, I also check the clock hasn't moved again.  If it does, I adjust the timers on our devices to match the meter time.

I've had E7 for years. It's an old purpose built, all electric flat with two switches for the immersion heater. I had no idea there were regional variances. I'm in the South East and now I find I've been starting the dishwasher at night at the wrong time. Thank you for this thread. Next step for me is to check my Electricity supplier for their hours. Wish I'd known this before but from now on... I'm on the ball.

@SunnySoleil ... 

The E7 times for the South Eastern region can also be 22:30 - 05:30 or 00:30 - 07:30 as well as time-split.

Your supply number (on a bill) can give a clue as to whether it's standard or complex ...

Refer to the MTSC ...


and look up in this table ...


If not there then it's likely to be split time.

Regulars always recommend checking meters with a torch at supposed transition times.

Regional Hours and supplier hours. Another question, as I'm a newbie and can't post my own yet. South East offers E7 in two stages 22.30 to 00.30 and 02.30 to 07.30. Does regional trump supplier?

Welcome to the forum.

Unfortunately the answer is not to check with your supplier because they don't set the E7 times.

It would be your Distribution Network Operator (UK Power Networks) but even that isn't the real answer.

Assuming it's just a standard domestic E7 set up, all that matters is what your meter is actually doing, not what anyone or any website thinks it ought to be doing.

Your lower rate times are probably 2230-0030 and 0230-0730 GMT but the only way to be sure is to look at the meter and watch it change over.  Better still, have one E7 spur (e.g. storage or immersion heater) fitted with a neon indicator so that you can see at a glance.

If your tank has two immersion heaters (and you don't have a boiler) the lower one should be on an E7 circuit and left on, and the upper one (Boost) should should be on a 24h circuit and left off.  It uses expensive daytime electricity so it should be used sparingly and only if you've run out of hot water during the day.

So as advised sit in front of your E7 meter and wait for it to click in and out of night and day time.

Do it then check when the clocks change for slip in minutes and that it shifts an hour.

It ain't rocket science but it does require a bit of groundwork for the end user.

Pedant FTFY reply caveat.

If you have a radio teleswitch the times can vary by +/- 15 minutes.   That's intentional, the variance is to manage the demand.  It's also likely that the switch will ignore GMT/BST, e.g. it will start at 10:30pm in the winter and 11:30pm in the summer.  Again, that's intentional so that local timers (for immersion heaters) don't have to be changed.

If your devices are on a switched circuit you don't have to worry but if you have a local timer or set the washing machine / tumble dryer etc to a delayed start then you need to be aware.

I live in the East Midlands area with a teleswitch.  Had it for over 30 years.  The lower rate is 01.00 to 08,00 all the year round.  
I worked in the industry and tleswitches were marketed on the selling point that they took account of GMT/BST so customers could take advantage of constant times all the year round. 
We in the East Midlands are lucky that 08.00 is a reasonable time most people can take advantage when they first get up.  I don't have electric heating, but my consumption averages 35% at the lower rate.

You checked if single rate would be cheaper.

Your likely to be pretty close.

Ofgem assume 42% when prices e7 multirate electric pricing.

The precise % vs SR moves quarterly - as the prices between average multirate and single rate Ofgem cap pricing can shift - like over 2p here in EM region last Jan cf 33p EPG SR average rates at time.
