Just had notification from Scottish Power offering me a smart meter. Is there  a definite view on these as to whether they should be accepted or not? Have done a site search on smart meters but was unable to find anything to convince myself one way or the other! Are they now able to differentiate between import and export? Despite all the hype I cannot see any real benefit to the consumer, it all seems to be weighted in favour of the supplier.
Does anyone recommend having one and do they cope with PV generation O.K.?
Being well past my three score years and ten I am starting to get thoroughly fed up with all this ever changing innovation - nothing seems to be simple any-more!

It all comes down to if you want the automation of meter readings the meters offer, or if you wish to make use of the new tariffs that will show up once the central data collection system is working.

At the end of the day they are still just meters. At least the one I have installed has no issues with PV generation, it is able to record the amount exported back to the grid. This is just a fun reference value as no smart meter is 'approved' for the value to be used for any charging purpose.

One thing to note is that if once installed you change provider the meter will need manual readings taken until the central data collection system is in place. This can be a pain depending on location as you have to keep pressing buttons to get the values out.

P.S. During the installation they do a gas pressure check - if it fails they cap off the gas supply until you have the issue fixed, so do not have the meters changed in the dead of winter.

Thank you for your reply. I understand that the meters send readings by wireless, have you had any issues with that? In this area mobile phone signals vary between poor and non existent. We have no worries about gas as there is no public gas network here! I get very annoyed by all the fancy adverts, which we receive, for services which are just not available in many rural areas.

I'm in south west London, so I've not had to worry about the mobile phone signals needed for my meters to work. Your location does raise 2 issues. Firstly current access to a working network, as I understand it many smart meters make use of the good coverage provided by the old 2G networks. Secondly what happens when the old 2G networks finally get turned off. In the UK there is no firm switch off date and operators have talked about the possibility of 3G being turned off before 2G as they need to provide 99% 4G coverage before they can drop 2G. This all could mean that a smart meter needs its modem upgraded in the future to support 4G, and there is a risk that it will stop working if the 4G coverage is not as good.

I get the feeling that unless you need a smart meter, it maybe best to sit back and watch the market matures as an 'advanced' meter in 2-3 years time would be better than being stuck with a meter manufactured today.
