Cheers for your advice! Honestly it's extremely unlikely I'd do it myself. I'd need to get at tonne of scaffolding and I wouldn't know anything about attaching the panels to the roof or doing any of the wiring!
Just chiming in to say that Octopus support DIY builds from non-MCS accredited installers. You can literally self-certify your build and feed it back into their grid.

Good to know, cheers!
I can fully understand the roof part, that you can always get a roofing contractor for installing they will do it for a lot less and likely much better than a solar installer will. But the wiring is incredibly simple there's literally just positive and negative on the solar panels. You just put them in series until you hit your desired voltage, then parallel strings after that. Solar panels use nice simple connectors that literally just click together, you plug those into some nice disconnect switches near the inverter and then from the switch to the inverter.
I love DIY maybe too much, but this strongly violates my "nothing structural, nothing roofing" rule.
They are both things I'd want a massive company to be doing, just from the sheer magnitude of the problems if they screw it all up.
Exactly. There's a high chance of me dropping a panel off the roof, or worse, myself.
