Hi chaps,

I wonder if someone can advise. I have a storage heater and hot water tank with dual controls. I've timers on one of each of the controls so I can set them to come on/off in conjunction with E7 times.

I have the below multi rate E7 meter.

The problem is it doesn't record a reading for the second rate. I had assumed it had an internal timer and switched between rates automatically. So that all the power in the property would be on the 2nd rate during E7 times. 

I've now come to realise I need an external timer switch to be installed as per the guidance on page 14 of the manual below.

Is this correct? What kind of timer switch would I need to have installed, and is this something the power company would do or do I need to have a private contractor do the job? And if the later, what is stopping me from setting the 2nd rate for whatever times I like to benefit from the reduced rate?

Pardon my ignorance!

Thanks!  

 
Is there no second reading, or is the second reading zero or some never changing value?

What does your electricity bill say? does it show a day and night rate?

It is possible for an E7 meter to be converted to single rate without swapping the meter.

 
It's switching between rates (1,2) but the second read is always at 0. 

The first meter was installed about 1-2 months ago, and due to this problem replaced by EDF for an identical one, but the same issue occurs. 

I think it's pretty clear it requires an external switch (based on the manual in the link of my first post and the paragraph copied below*) but the engineer didn't mention anything about it when installing either meter, which makes me think he was a) a bit clueless, not out of the question I suppose or b) expected me to already have it sorted on my side and therefore it's my responsibility.

Just for the sake of clarity it isn't actually my property but one I look after, the bill will be in the tenants name so I can certainly find out about that. 

*The configuration is factory set allowing the meter to operate as a single or two rate meter. Rate switching is achieved by switching neutral or live to the input terminal. See wiring diagram for the D model. 

Additionally, page 11 of this document seems to suggest the time Switch is the responsibility of EDF.

If anyone could clarify that it would be very helpful. Just a bit odd that none of the engineers would have mentioned this.
