Noticed exactly this over the past 18 months. Standing charges are the silent killer — Octopus has mine at around 61p/day now, which means I'm paying £220+ annually before I've drawn a single watt from the grid. Absolutely mental when you think about it.
My setup pulls from grid maybe 3-4 days a month during prolonged clousy spells when the Victron Multiplus can't keep up, but the bill structure means I'm essentially subsidising everyone else's grid dependency regardless.
What really stings is that Ofgem keep framing standing charges as "network maintenance" costs, yet those of us who've invested heavily in Fogstar lithium banks and decent solar arrays are arguably reducing strain on the network. We should be rewarded, not penalised with flat-rate charges that ignore usage patterns entirely.
I've seen a few people on here mention going fully islanded to escape it entirely, but that feels like an extreme response when most of us have grid connection as a genuine emergency backstop — which is precisely my use case.
Has anyone actually done the maths on whether surrendering grid connection and relying purely on a properly oversized battery bank makes financial sense long-term? Curious whether the standing charge savings eventually offset losing that safety net, particularly heading into winter months where my consumption and generation are furthest apart.
Worth discussing whether lobbying through something like the Microgeneration Certification Scheme community makes sense, or whether that's hopelessly optimistic given current regulatory appetite.
