Anyone else noticed their electricity bills gone mental this month?

Just had my quarterly statement come through and even with the solar + battery setup on the garden office, the main house bill has crept up noticeably. Still miles better than before I installed the system, but the standing charge alone is getting offensive — nearly 60p/day now depending on your supplier.

Curious whether others are finding the same pattern: the unit rate gets all the headlines, but it's the standing charge that's quietly doing the damage for anyone who's already reduced their consumption significantly. There's almost a perverse incentive at play — the more you offset with renewables, the more the standing charge represents as a proportion of your actual bill.

I've been seriously reconsidering whether full grid defection makes sense for the house (not just the office), though the numbers still don't quite stack up for heating loads in a UK winter without going seriously oversized on battery capacity.

Anyone else running the figures on this? Specifically interested in whether people are:

• Hitting the threshold where standing charge vs. full off-grid battery costs actually balances out
• Finding their DNO is being cooperative (or otherwise) about any export arrangements
• Noticing regional variation — I suspect Scottish hydro tariffs are a different story entirely

Also wondering if the Ofgem price cap review in the spring will address standing charges at all, or whether that's wishful thinking on my part.

Would be good to hear from people running larger setups — narrowboat folks especially, since you've presumably already solved the "zero grid connection" problem in ways that might translate to a fixed property context.

@RogerKnight yeah the standing charge creep is the silent killer isn't it. Even when you're barely drawing from the grid, Octopus/British Gas still get you on the daily rate.

My motorhome setup taught me to obsess over actual kWh consumed rather than the bill total — sometimes the two tell very different stories.

Worth checking if you're on the best tariff for a hybrid setup. Agile can work well if you're charging batteries overnight at cheap rates and leaning on them through peak hours. Some folk on here swear by it with their Victron kit.

The bills going up is grim but at least you've got the buffer — imagine what it'd be without the solar. 📈

Yeah @RogerKnight the standing charges are genuinely infuriating - you can be practically self-sufficient in summer and still owe Octopus or whoever a tenner just for the privilege of being connected.

One thing worth looking at is whether you've optimised your export tariff alongside your import rate. A lot of people nail the generation side but leave money on the table by not shopping around for the best SEG rate. Some of the Agile-style tariffs can also work really well if you've got enough battery capacity to time-shift your grid usage to the cheap overnight windows.

What battery system have you got on the office? Depending on capacity you might be able to pull the whole house peak demand through it during the expensive evening slots. Makes a noticeable dent on the actual unit cost side even if the standing charge is largely unavoidable.

Standing charges are one thing but wait till you see what winter does to a shepherd's hut setup 😅 No mains connection here so I've dodged the bill shock entirely, but the flip side is you're watching every amp like a hawk come November.

Honestly going fully off-grid was the only thing that actually fixed it for me rather than just softened the blow. My Victron kit gives me proper visibility on what's happening and when I'm running low I know exactly why.

@RogerKnight the garden office hybrid approach is still solid value though — you're never going to hit zero on a grid-tied setup but you're still well ahead of where you'd be without it.

@RogerKnight the standing charge issue is worth tracking properly rather than just eyeballing quarterly statements. I run a spreadsheet logging daily grid import against the static caravan's battery state-of-charge — once you separate standing charges from actual consumption you often find the consumption figure is more manageable than it appears.

The standing charge itself is essentially unavoidable unless you go fully off-grid and terminate the supply agreement entirely, which carries its own complications around reinstatement costs if your situation changes.

Worth checking whether you're on the most appropriate tariff structure too. Some suppliers still offer economy arrangements that interact reasonably well with battery systems if you're charging overnight. Whether that arithmetic actually works out depends heavily on your specific usage profile and what your Victron (or equivalent) is actually logging.
