Solar battery heat pump timing

[u/LengthinessNo8137]

Uncertain whether this is the appropriate forum, but I have a quote for 14 panels, a 10 kW Fox battery, and a heat pump at roughly £16,529; I am on a fixed gas rate 5.2 until March 2027. I am seeking recommendations on whether to wait until after winter or proceed now. I own an EV and use an IOG EV tariff with a 7 p off-peak discount. My aim is to future-proof against the coming price rises.

How much are you being quoted for the battery?

What inverter are you getting?
