Mine are separate. At the moment I see the money applied to my electricity provider and nothing on my Gas account. They keep checking my address is correct so I am thinking they can see a unique address and know electricity and gas are split supplied.

Mine is 17:30-18:30, are the times different across the country?
Kid is out and so am I not our best time to save but I can isolate the whole house via the PowerWall ;)

Just had a quote for battery storage, hows this compare?

"We believe the best battery match for your existing system would be an AC coupled battery system installed to protect your existing FIT payment, the best option is probably the Giv-Energy 3.0kw AC coupled/9.5kwh battery storage.

The fully installed and commissioned cost of this system would be £6840.67 inc vat @ 20%

This system could be expanded by the addition of another battery if required as you have quite a high energy demand, the batteries can also take advantage of cheaper overnight energy from suppliers such as Octopus enabling you to further reduce your energy bills, an additional battery would add £4094.40 inc vat to the cost"

£5k inc VAT for the same kit, not in stock though, somewhere else the price was £6.5k for the same setup, and £7K elsewhere.

The are also quite easy to install if youre good with electrics.

One thing I would say is that this is the same 3KW output as my inverter and when the solars not generating you can end up still pulling from the grid if you max out the 3KW capability which is easily done just by turning the kettle on.

I bought my second slave solax battery from this company and it arrived the day they promised (was slightly messed around by another company) so can deffo vouch for them.

Tesla PowerWall 13.5kW usable with 5kW draw, 7kW if solar is good. Ability to totally isolate from the grid and go truly off-grid.
Feature full but expensive option.
Opens up Tesla Energy Tariff with Octopus for 11.24p import and export so might cause issues with your FIT. Also, needs smart meter.

Google says from June 2022

How much does a Tesla Powerwall 2 cost? The total cost of a Tesla Powerwall 2 before installation is approximately £9,390 in the UK. Including installation the price is between £10,290 – £12,190. The Tesla Powerwall is considered to be relatively good value for money in terms of cost per kWh of storage.

Might have gone up since then though, not sure I aggree with the last part of the answer though, doesnt sound good value to me,

As I said, full of features I wanted, so I paid for them.
I ordered in early 2021 when it was one of the largest storage batteries with a ne of the easiest integrations. The price was also lower but did go up by £500 as we waited 8 months for it.

Installation costs should not be a couple grand, its not like they need all the scaffolding and bolting panels to your house like with a full pv install, its just bolting a big beast to your back wall and adding an inverter somewhere? should be couple hours work max? (they did my whole pv install in one morning was insane!)

You are underestimating what it is.
It is a whole new distribution board with a dual feed, from the battery and from the grid. Your previous distribution board becomes a sub panel.
My install was basic. Mount battery, fit new distribution board, move connection from meter to new board, connect new board to old board. Connect battery to new distribution board. New earth for the new board.
Wired and wireless connection.

And the battery has an inverter in it.

I can see the cheaper options and know for many they are all they need. But I wanted what I paid for.

Of course. Big name that people wanted to be associated with and before Elon made some questionable decisions. But I believe the batteries are still highly rated, just with Tesla tax added for price.
I am not sure I would justify it now. But at the time, my total install was equivalent to various other quotes I got.

Hmm ok but more work then I thought but not seeing couple ks worth?

I held off responding, deleted a few responses and left it a few days to rationalise. My view is we are not comparing like for like and using personal experience to say one thing is not worth the cost vs another, but we all want different things so it is good to have options. I have tried to be open and fair on the costs below.

If someone can install this themselves, then paying £5850 for the linked AC battery is clearly cheaper but there is a value to the time you spend installing. Plus, you have to have wanted an AC battery, not a DC option, and have the ability fit it. This option will not allow you to have a newer export tariff (rather than on an estimated FIT) (unless you can sign off the paperwork yourself).

Comparing the battery part of the PowerWall with what I paid and adjusting the above £5850 to 13.5kW and we get £7140 (PowerWall inc VAT) vs £8313 (GivEnergy adjusted to 13.5kW inc VAT). That is without the Gateway which lets you disconnect from the grid in a power outage. Prices for the Powerwall will have gone up based on what we have seen (~13%) but assuming the Gateway and Battery increase is equal, the Powerwall battery is still similar price as the linked one above (£8068 vs £8313).

The Gateway is the significant extra and was £1008 in 2021 (inc VAT), assuming adjustment of 13%, £1139 now. This is a complete distribution board with dual phase feeds plus battery feed. It is a hub that communicates with central servers to allow them to charge and discharge the battery and gives the option to join the Tesla Energy Tariff. It is also one of only devices that I know of that is certified to disconnect your house from the grid so your house won't backfill to the grid harming local engineers, therefore it can stay powering your solar inverter in a power outage. Dropping this option is possible and will reduce the install cost.

My install cost £1440 (inc VAT) for Installation, testing, commissioning and notifications, plus delivery. 3 guys over 2 days, 2 dedicated electricians, call it 4 resource days.

If you can do your own install and it won't affect your export tariff, then self install is a good way to go. If you want certified, you are going to pay for install, if specialised work then you will pay more, I also paid more for the complexity of my property and the location of the battery and the Gateway. Each home install will be slightly different, there is no way my panels were going on in half a day, or my battery was being installed and commissioned the same day, so I paid extra for installation.

Write from the heart it’s the only way :D
Nice write up, explains all the various costs very well. Looks like your install cost was very reasonable compared to some quotes.
