It really is a mine field. I phoned my insurance co to add mods and they said they couldn't insure me. Left me with looking for alternative.
Aplan was nearly £500 which was with mods added but everything else on top such as legal cover.
Did online quote with LV, declared the mods, spoke to a human as well to confirm and that was £70 quid cheaper with legal, protected NCD, and an online discount .works out £39 per month. Still a lot, but has to be done.
