FWIW
A few years back I had 3500L Rover Trike insurance locked garage only. £3750.00 value
Then I got a Quad,insurance,
Thatcham approved alarm,chain, bolt anchor,locked garage,I was not even insured if I was in a 500 yard radius from my home if I left it in the street unlocked or chained, took the pi$$ I think considering a bistro pub I like going too is in that radius
Value £2000-£2500
In that time i had various ebikes which was insured,locked garage nothing else was required. Value £600-£1400
Also what is one person insurance is not the same for all even with the same company, Postcode is big factor which goes inline with risk rates.. IE reported thefts in the area and what is high risk
