@DHogg I found this on the Ofgem site which I suppose is what SP have agreed to support
For those interested, here is some sample data I downloaded from EDF showing what 1 energy provider currently provides consumers as a csv download.
It's a long way short of the half hr read data I used in Oz to work out if Time-of-day tariffs were best for me, but as I haven't seen TOD tariffs in the UK, it will at least help people see how little changes in day to day activities can make differences to there usage.
Oddly (given it is the electric meter that sends the data) all electricity readings except last are estimated. All gas except one are actual. There is provision for daily reports with half hr reads but this isn't populated yet. Much like SP graphs, actual read data is several days behind and whilst balancing overall, can be ± 3kWh per day with Gas

@DaveBev Looks like your daily usage has dropped due to warmer weather, but you need a higher DD to pay off an accumulated debt from winter. Pay off the debt and your DD will drop.
