Someone I know is in the process of buying a house which has a British
Gas smart meter installed. Ignoring for a moment the portability issues
to a new provider, I presume it comes with some sort of SED (smart
Energy Display) which sits on a shelf somewhere a bit more accessible
that six feet under the stairs.

If the vendor has lost (or otherwise fails to hand over) the SED, how
easy is it to get a replacement?
