Good point about the labour costs etc.
I think since Feb this year they're VAT free even just on their own:
https://www.gov.uk/guidance/vat-on-energy-saving-materials-and-heating-equipment-notice-70862.19 Batteries for storing energy converted from electricity ... the installation of a standalone battery for storing electricity from the
grid (the mains electricity)but yep that's not forever so worth thinking about
-
Thanks, that's really good to hear!
Electricity usage isn't particularly heavy so even 9.2kWh sounds a lot. I assumed batteries were the easier part to expand in the future (no scaffolding etc etc) and one area where tech/cost may change more rapidly.
No plans for a heat pump but I should probably read into it a bit more. -
Would be interested in opinions on a solar quote I’ve had, or on any of the components in it.
Around 8 months ago I got a few quotes (Octopus/Eon/local) for ~12/13 panels and a 9kWh battery which all seemed to be around £14k, which seemed expensive and too long a pay back period.
I signed up to a Solar Together Surrey group buy interest list and have had the following initial quotes (these are just prices without a visit to confirm).
Pricing seems a lot more reasonable, just interested if people more knowledgeable than me have any thoughts on either the pricing, the components used or questions I should be asking:

In case you didn’t know the next version called Tado X is available in Germany I think but not here yet, I’d expect it to be released here at some point soon.
It uses thread/matter for communication and the trvs have a rechargeable battery.
