Hi Korey. Thanks for your kind comments about my Trading 212 review. I’m sorry I don’t have the specialist expertise to comment on this subject or (to be very honest) the time or inclination to delve into these matters in detail. Also, I have to be careful what I say publicly as I am not a qualified financial adviser and don’t want to fall foul of the regulatory authorities here. I wish you every success with your project though.

Indeed … and not dissimilar to the practice of ‘gaming the denominator’ so prevalent in Corporate KPIs and Government stats. telling us all how brilliantly things are going by altering the value of the total (in this case daily energy burn i.e. denominator) against which the daily peak (i.e. numerator) is being compared. So in theory (if you have the capacity to store or are prepared to just pay) you could get free Sunday Saver energy by leaving your peak time burn unaltered and just increasing your off-peak burn enough to tweak the swing percentage. That’s essentially why of course EDF don’t really lose out because in the end we’re still buying their electricity, just at a different time because our totals won’t change that much (apart from seasonal heating if it’s electric like mine). So those with a big battery on wheels that they can charge at home like Harry are the clear winners here 🙂 … the rest of us are left topping out our existing ‘house’ batteries if we have them, or wondering what to switch on of a Sunday for the next 8 – 12 hours after we’ve done the obvious and run all the major appliances. Personally I found that without batteries I would be done running things like dishwasher, washing machine, vacuum cleaner, oven etc. well inside 8 hours on a Sunday. There was no real point aiming for 12-16 hours because I would run out of high load appliances to use by 4pm (apart from the electric radiator when required).

So you’re inflating your weekly off-peak usage total by topping off the big battery in the PHEV to make your end of week ‘swing’ from peak to off-peak look healthier thus earning some freebie hours on the following Sunday. Smart! 🙂
Plus I guess the recent energy price cap reduction effective until April coupled with the undoubted petrol price increase now coming down the line makes your petrol-electricity comparison look even better. Double smart!! 🙂 Nice one.

Thanks, Sally. It surely does! Currently my SIPP (personal pension) is in flexible-access drawdown, but as I get older I will certainly consider switching some or all of it to an annuity.

I think that a lot of people with proper house-battery installations and solar feeds to match (like Nick here) drop out of the Sunday Saver scheme once the sun starts to shine because they can generate enough for free anyway through the summer. I certainly wouldn’t buy batteries and/or portable power stations purely to take advantage of Sunday Saver simply because the number required to make any real difference would be both prohibitively expensive as well as logistically complex to accommodate and utilise effectively. The most likely year-round beneficiaries of the scheme would be EV owners I guess … but as you say who knows what changes to T&Cs and market regulations await that are likely to affect that particular dynamic? Personally I stick to Standard Variable Rate because my energy footprint these days is much reduced and I doubt that any fixed rate ‘deals’ in reality make that much difference to my personal situation. So I’ll just stick to SVR, charge my batteries on a Sunday for free for as long as it’s available and reserve the right to switch supplier whenever I like. I doubt any of the ‘offers’ we will be bombarded with next will see any suppliers suffering losses or price instability on the scale that occurred at the start of Putin’s latest expedition anyway. Happy hunting!:)
