We have 3 x 3kW storage heaters running on an ancient tariff called Tariff 19!.
I think we may be the only ones in the UK still running this tariff :-)
After my mum had her second meter removed a couple of months ago I
think you are right.

Presumably they would have to remove the existing Tariff 19 meter and timer box,
fit a new E7 meter (or retain the existing one - which is only 1 year old) and
jumper the existing feed to the heater CU into that meter (to still feed the
heaters from it's own CU). I'd like to change that heaters' CU myself for a new
one with MCB's and an RCB Any problems with any of the above so far?

Any idea how much I sould expect to pay for the elec. co. to do the changeover
to E7? Any hidden surprises I could expect - like "we'd only do it if we rewire
the whole house". Or even have to retest the whole installation?
I had thought meter _type_ changes were free but then I've only made the
conversion from E7 to single and from your Tariff 19 (or equiv) to single. Not
an authoritative answer I'm afraid but I know that type changes are
monitored as a performance indicator so your supplier should be quick off
the mark with making the change, and (hopefully) giving you a price (if
any).

If they should want (say) just to test the 3 heaters via the new CU, could I
drop the heater feeds from the CU so it isn't feeding anything (and so nothing
to test)? As I'm going to retest that myself anyway when the new heaters are in.
Do the new regs affect whether I can - sorry, "am allowed" to do any of the
above.
I would get your new heaters in with new CU etc and connect to your old
second meter before asking them to change, then the guy will come & see
a bright & shiny new (but pre Apr2004) installation waiting to be changed
over.

I'm assuming electricity is you only option?
