I think someone on here has been very knowledgeable on this in the past and should be able to answer.
Best guess based on comments above.
Ask them what model of meter they fit and the information should be available through Google like just about everything else on the planet.
https://www.uswitch.com/gas-electricity/guides/smart-meters-explained/I understood that the first generation smart meters (SMETS1) did indeed have a supplier lock in and so went dumb if you changed suppliers.
https://forum.ovoenergy.com/smart-m...tility-are-they-compatible-with-ovo-5460 I think the new generation (SMETS2) have cross supplier capability and so if you swap billing agents it remains working. Worth asking what they plan to install.
The size of the smart meter in MiL and our home is really not that big. See bottom for link and specs.
An example would be the Secure Liberty 100 is a unit installed in MiL internal closet. I believe it is SMETS1 and has been used by a lot of companies.
The first installation of a smart meter is government subsidised/funded but replacements will be chargeable from my experience of our MiL's installation.
You will gain from having one in the future as the tariffs will benefit from cheaper overnight charges when there is a surplus (at least until we all start charging our electric cars).
an eco point of view it has real benefits so is not to be ignored.
The more we think about it the more we should reduce consumption all being well.
I totally agree re reading the bill requiring a Diploma. The only bill I hate more is the BT bill for the phone line, what a farce.
