If you want a smart meter (which is a different debate), then you've got to make sure you get the second-gen SMETS2 meters. These should not go dumb when you switch from one supplier to another.
There's a few smart meter threads here already.
As of March 15th all suppliers have to install SMETS2 meters they are not allowed to install or use up SMETS1 stock.

and it's only going to get worse as the call centre is getting farmed out to India.
