Also about to put a deposit down on 14 solar panels and a 7kWh battery to be installed in the new year.
In addition to the ASHP woes above, I've talked to (and paid £500 to) Octopus about a solar survey. They reckon they can get 5 panels maximum on SW side, but the NE of the house has more potential... Not feeling it for just 5 panels (£5400 for just panels, +£3k for 5.2kWh battery) so if the NE thing doesn't work out, I won't go forward and hopefully will get my deposit back.
