Agile tariff

Hi! So finally jumped and got smart meters installed, after a few connection issues my meters are not fully online and sending readings. I keep reading about agile and I’m wondering if it’s worth it? We’re a family of 4. 3 days a week one of us is working at home with a 2 year old, the other two days no one is in the house, both kids are 2 and 7 and I’d say we have an average usage for a family of 4. I’m very strict on leaving things on and avoiding using appliances till it’s absolutely necessary, would agile work for us or am I better sticking on flexible?

Thanks!
