Come Summer I would expect the battary to often be full and you to be gifting a lot of energy to the grid.

Unfortunately, at the moment with EDF and on the tariff I'm on i cannot sell back, but its something i will be looking into

With a non smart meter I have read the best thing to do is one night wait up and watch the meter switch over and it's 7 hours from that point.

You read some very bad advice.  Could turn out to be a very expensive learning curve if you discover years later that it's actually 2230-0030 and 0230-0730 GMT.

Yeah ours has one hour off peak, then an hour peak, the off peak for the remainder.

Although watching it switch would confirm rhe point about GMT/BST.

I have an E7 smart meter. The actual switching to off-peak rate remained at the GMT times although the clock display time did change to BST.
As has also been mentioned, your nominal hours may be 0030 to 0730 GMT but the actual switch time is decided my the regional electricity supplier (that's not your billing company). Mine is actually 0039 to 0739 GMT.

If smart meters are so 'smart' why can't they just show my E7 rate switch times?

My IHD "sort of" displays the E7 switch times BUT it is wrong because, it shows a count down in 10 minute blocks on the RHS of the display starting one hour before the "supposed" change. This is based on the nominal off-peak/peak times - mine 0030-0730 GMT rather than the exact time of switch 0039 & 0739 GMT. This is due to the two lots of information being stored in 2 different registers.
This is clearly poorly thought through programming, however I suspect it's a historical problem because when the basic idea of smart meters was developed they didn't give a lot of thought to multiple rate tariffs!
Whether the actual times/registers on the meter can be displayed by "playing" with the buttons on the meter, I haven't a clue as I can't find any destructions on what all the "options" with the two buttons on my meter do, and I don't want to risk messing something up.

I am with Eon Next on an old fashioned meter and mine change when the clocks change even though Eon say they shouldn't so my cheap rate ends at 6:30am in the Winter and 7:30am in the Summer, you are doing the right thing by making your own checks.

Hi @gambleruk
May I ask what region your in & what your MTSC is?
