Been offered the following 

15 x jinko tiger neo 435n type panels
G3 givenergy 5kw hybrid inverter
9.5kw gen 2 givenergy battery 
Givenergy eV charger

Fully installed by Mcs certified installer, dno, scaffolding etc

Total cost is £11347

Haven't had any comparisons as other quotes have been using sunsynk / SolaX but looking to use the givenergy stuff.

Seem a good price?

Looks to be in the ballpark. Personally, I'd be looking at the Givenergy All-in-One, as with bits included gateway it offers islanding, in the event of a power cut, and you can charge/discharge at 6kW, so it will cover most appliances without the need for additional grid import.

I'd recommend a 5kW SolarEdge inverter (20 year warranty) AC coupled to the GiveEnergy All-in-One battery.

~£13K installed, which is a 10% cost premium for 40% more storage and a superior inverter w/ longer warranty.
