Anyone else noticed their electricity bill creeping up even when they're barely on the grid?

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.

@CamperDan this is exactly why I built my van system before anything else — started noticing the standing charge creep back in 2022 and it genuinely horrified me.

My setup is 400Ah of Fogstar Drift LiFePO4 with a Victron MPPT doing the heavy lifting, and I've progressively offloaded more household loads onto a matching home battery bank. The maths were brutal once I actually sat down with a spreadsheet.

The standing charge is essentially a subscription fee for a service you may barely use. What really stings is that even if you generated 100% of your consumption via solar, you're still paying that daily ransom.

Worth looking at whether Octopus Flux or a similar tariff reshuffles things in your favour — some members here have had decent results arbitraging the off-peak rates against their storage capacity.

@CamperDan £220 just to exist on the grid 😂 It's basically a subscription fee for electricity you're not even using. Netflix at least gives you something for your money.

My garden office runs entirely off a Victron/Fogstar setup now and honestly the standing charge is the main reason I've never looked back. Did the m

@CamperDan worth noting that standing charges actually vary significantly by region — not everyone's paying the same 61p. Scottish/Northern networks tend to be higher, IIRC. Something people don't realise when they compare bills.

What gets me is that even on my boat (where I've essentially built a full Victron-based backup system) I still keep a tiny grid connection for... reasons. Mostly peace of mind in winter. And that standing charge just quietly bleeds money the whole time.

The honest calculation people should do: take your annual standing charge figure, then ask what battery capacity that money would add to your off-grid setup each year. Fogstar cells aren't exactly expensive per kWh anymore. After 3-4 years the maths gets quite uncomfortable for the grid suppliers.

Not saying go fully off-grid necessarily — but the numbers do make you think.

@CliffGazer good point on regional variation — I checked mine recently and was genuinely surprised how much it differed from what mates in other areas pay.

Honestly the standing charge situation is what pushed me to properly sort the narrowboat system first. Now the house battery (Victron + Fogstar 200Ah) handles pretty much everything and I only touch the grid when I absolutely have to.

The maddening thing is you're essentially paying a penalty for not using it. Use less, still pay the same fixed chunk. Doesn't exactly incentivise efficiency does it.

Only real way round it is going fully off-grid or finding a tariff with a lower standing charge — though those tend to push the unit rate up to compensate, so you've got to crunch the numbers for your own usage pattern.

@CliffGazer that's a really useful point — do you know if there's a reliable way to compare standing charges across regions? I've been on the same Octopus tariff for ages and just assumed it was standard.

Asking because I'm trying to work out whether it's actually worth keeping my grid connection at all. Running a Victron setup in the garden office and the van is pretty much self-sufficient, but the house is still on grid. If standing charges keep climbing, I'm wondering at what point full disconnection (or at least dropping to a minimal export-only arrangement) starts making financial sense versus just eating the daily charge.

Has anyone actually done the maths on this properly? Feels like there must be a crossover point depending on your usage profile.
