Economy 7 and smart meters.

posted by geoffsid | A week ago

Hi all,

             SP inform me that I can't have a smart meter with Economy 7 storage heaters. But as I already have E7 storage heaters with a radio telemeter (which will stop working in 2023 when the long wave radio signal is turned off by BBC), this is something of a problem. Am I expected to install oil, lpg  or heatpumps at a cost of many thousands (no mains gas)? I know that other energy suppliers are offering E7 smart meters with five terminals which can switch the night rate circuit on/off at the appropriate time.

This is the weird reply from SP when I posed the question:

Thank you for your recent e-mail regarding metering  query  of your energy account xxxxxxxxxxxx.

I have checked the account and I can see your area is showing smart ready . In that case if you will remove the storage then we will install smart meter at the property.

You can have smart meter with the below check points :

 If the you do not have storage heaters or under floor heating you can have a smart meter installed,

 If the you have storage heaters or under floor heating installed you  cannot currently have a smart meter.

We are in the early phrase of installing Smart Meter and we are continuously upgrading our technology.  we are upgrading out technology to adopt them, so that without replacing the meter we can use them as a Smart Meter. Once it is updated we will send the details to the engineer and they will update the details accordingly.

Please be confirmed mobile signal and metering signal compatibility is different.

Your patience and cooperation are highly appreciated.

@geoffsid    Sorry about that, you need to speak simple English to them, say please remove your Comfort Plus system from my house and install a simple Economy 7 system.  If you insist they MUST do this for you.   It's a problem with this old SP system.

Re: Economy 7 and smart meters.
Thanks for the advice, I am wondering who best to speak to about ordering the smart meter as I realise it must be done if the storage heaters are to remain operational. But I have heard several horror stories about smart meter installations leaving the storage heaters out of commission because the fitters were not conversant with E7. Also there is a big question mark over the communications, ie. very poor mobile signal and no close neighbours for the "mesh" system. So I really want to speak to a knowledgeable technician before going ahead.

Re: Economy 7 and smart meters.

@geoffsid   You are right to be cautious.  Only SP can remove your Comfort Plus, and it is up to them to decide what sort of meter to replace it with.  When the fitter comes spend time talking to him to explain about your storage heaters and the need for a good E7 system.  He will decide if smart meters would work at your location, and if they do not SP will have to install conventional E7 meters.  Once you are on the new system you will be free to change supplier.

Re: Economy 7 and smart meters.

@geoffsid   Thanks for the 'Top Answer'  One thing more,  your house is probably wired so that the storage heaters are on their own separate circuit. Conventional meters have a time switch which activates that circuit and it gets cheap electricity, but the rest of the house remains on normal priced electricity.    Smart meters work slightly differently, they change the tarrif pricing for the whole house without switching on a separate circuit.   So it is importnat that the fitter understands that and that he adjusts the wiring so that the storage heaters are supplied like the rest of the house. 

I believe this is correct but I'm not an electrician and you could ask a local chap to check your wiring.  (There are also some old types of economy 7 meter that switch the whole house to cheap electricity)  Once you know what is going on you will be able to give good advice to the smart meter fitter.

Re: Economy 7 and smart meters.
Yes the storage heaters are on a separate circuit with their own fuse box, they have to have their own circuit as the household consumer unit would be overloaded by the storage heaters. That is why a special 5 terminal , second generation smart meter is needed. I have taken the plunge and made a smart meter appointment. I found it impossible to speak to anyone at Scottish Power with technical knowledge so advised this requirement on the web booking portal (as suggested by the SP call centre). However I have no confidence that a successful installation will be possible, especially as at least three neighbours have had installations aborted because of the weak or non-existent mobile signal (which I also mentioned). But the installers have confirmed the appointment, I won't let the fitter proceed unless I am 100% sure he knows what he is doing. It is a pity that it seems impossible to discuss these matters with an engineer before making the appointment. I will keep you posted. PS. SP insist that they are now installing smart meters in this area?
