I'm with octopus (got moved to them when my previous supplier Avro went under) and had them fit a smart meter last year.
I took part in their trial to reduce usage in allocated time periods to receive payments in reward. I think over the entire trial period I earnt a couple of pounds. Saving energy in peak periods was quite easy as I'd just cook my tea later and not put the washing machine or dishwasher on during that time, but in the trial there were also some odd times of day like early hours of the morning or mid morning when I would be asleep or out at work so I wasn't using much power anyway at that time so couldn't reduce my usage.
They calculated my savings against my historical usage which they had recorded from my smart meter. I opted in to having my meter send half hourly readings so they will have detailed statistics for my usage.
To be honest for the rewards offered during the trial for the trouble of cutting down usage it wasn't really worth the bother, but I would imagine national grid have realised this hence possibly rewarding people with up to £6 per KWh of reduced usage - for that much reward I'd put a lot more effort into cutting back in peak times!
