Agile import has gone negative in the East Mids quite a few times in the last month, our last monthly bill to the start of October showed an average rate of 11p per unit consumed, so far this month we're averaging around 10p/unit. Obviously all the negative rates correlate with windy weather but so far on days with no wind (and hence higher rates) we're getting decent sun - certainly enough to top up the battery.
Our PV self-consumption is 96% even in summer which helps as export rates aren't a factor at all 🙂
I have no doubt there are going to be weeks or months where we'll be paying through the nose for import but so far Agile is saving us more than 50% on a SVR (27p/unit) contract from someone like EON, who were our previous supplier. That's just from load shifting on a 3.6 G1 hybrid with a 9.5kW battery using some automation.
If you don't have an EV/heatpump but do have a big enough battery to dodge the 4-7pm peak period (and ideally go all the way from 4pm to 2am) then its hard to see past Agile - provided of course you take advantage of the lowest rates, which can present a challenge in managing battery SoC to maximise that.
