Energy Efficient Appliances: Upgrading to A rated white goods

£999?

with those energy usage numbers it would cost me ~4.5p a cycle rather than ~9p (I'm on Octopus Go, and run it almost exclusively every other night).  As much as I love to save energy, it would take me ~60 years to get the money back over buying say a £500 dishwasher.  That being said we buy all our white goods second hand, use them for about 5 years till they fail, which is arguably far better for the environment as they'd go to landfill otherwise.

Hopefully the technology implemented by Siemens will become more accessible as time moves on.

We sold the old unit on to a low use household for £300 and paid 10% less but yes, definitely not an affordable option. That said, it may help reduce battery depletion, leading to the need for a smaller battery (we don't own one), and may suit the right household.

For us, this is part of our personal goal to reduce household electricity import to less than 1.5K kWh per annum.

About 30 years in our case, it would save around 8p per load. Our dishwasher cost less than £300 new a few years ago, so I'd be surprised if we'd get more than £50 for it second hand. I'm amazed you were able to get someone to pay £300 for your old one.

We sold on our 5 year old AEG washer dryer on for £250. We typically sell our appliances on vs. dread the inevitable unplanned breakdown.

Admirable goal!

I'm hoping there's 2 or less people in your household, otherwise this is going to be very difficult.

Dare I say it, a battery would probably get you there quite easily.  Our import dropped from ~4000 kWh (PV only) to ~2200 kWh just by adding a battery to collect up all the energy we were exporting for nothing (I'm on deemed export).  We didn't change anything else and if anything our energy usage has probably risen, as my children are now energy hungry teenagers.

We have averaged ~1650 kWh p.a. prior to the energy efficient appliance upgrades (Oven 500W + Washer Dryer 300W + dishwasher 500W savings),  and may just about make it. I will report back in 15 months when we have a full year's ('24) data. Not quite Passivehaus but "Pragmatic-haus" perhaps?

We've gone back and forth on a battery for a while now. Eventually, we decided to invest in an additional 3.3 kW of Solar PV on our West South West aspect (6 X 550W Sharp Bifacial panels) instead, to be installed next week for the same price as a cheap, small battery. Apart from the better return, we went this way for two ethical reasons primarily 1) the grid is filthy when wind speed drops during the warmer months, needing as much PV as it can get 2) we would rather the Lithium was used in an EV where it would offset more carbon.

Fingers crossed all goes smoothly!
