There are a lot of variables that need to be factored in, and they don't cover many of them in these cheaper quotes.
What size inverter? Is it a hybrid inverter? 10kWh of Storage is 8-9kWh usable because batteries are only warrantied to 80-90% depth-of-discharge, is that enough?
Since there's only ~5.6kWp of panels in that quote it's probably over-provisioned, and it will likely come with a smaller inverter, say 3.6kW, which is what a lot of these cheaper companies will do, and export will be limited under G98 to 3.68kW.
That also means that in peak sun, your 5.6kW of panels are going to clip at the inverter capacity and you won't be able to access more than that limit in power.
£200 per extra panel isn't bad, the company I went with charged £300, but mine came with per-panel optimisers (at my request, mainly for the monitoring functionality rather than optimisation). If I wanted to add an additional elevation though, that would be per-panel cost plus ~£2000 for the additional elevation of scaffolding.
If you're going for one of these installations and haven't already, ask these questions, and if you can get a decent price that's great, I wish you luck. I'm not on reddit so I can't comment on the quality of that sub.
