What are the times for the (reduced) night economy 7 tarrif? Does this apply to British Summer Time (i.e. after the clocks go forward)? I live in Cambridge, UK.
Normally 0000 to 0700. When you change the clocks forward, it’ll be 0100 to 0800 unless you have a smart meter. In that case, it’ll be 0000 to 0700 all the time.
The timings above are approximate.
Hi @b.i.ahmad 
and welcome to Community 
Sorry for the delay in my response here.
As @Anton59 has said the standard economy 7 off-peak timing is 0000 to 0700 which yours is too. As you do not have a smart meter your economy 7 timings will change when the clocks go forward too.
If you have any other questions please drop them below
