I'm in England, and currently on a single-price electricity tariff, that's measured by a (very) old-style electricity meter (mine says "property of Eastern Electricity Board" on it, so it's well over 20 years old).
After my previous question on how to decarbonise my home heating - How can I decarbonise my domestic heating, given severe physical constraints? - I think my best bet is to to put in electricity storage heaters, and a hot water tank with electric immersion heaters.
If I want to move to a time-of-use tariff, such as Economy Seven, then that would require more sophisticated metering. At the very least, a second old-style meter, which has been standard practice for dwellings on Economy 7 or Economy 10 for 30-odd years.
However, Britain is just starting the process of switching from old-style meters to smart meters.
So, if I want to move to a time-of-use electricity tariff, how do I get an appropriate meter fitted, and what should I be looking for, if I want to take part in the forthcoming demand-side response market?
(I get my electricity and gas from Ecotricity, if that makes a difference)
