Ok, I'm forty and I've 9yrs NCB,
Here is what I told them:
I limited my mileage to 6000m,
Vehicle in a locked garaged overnight,
Thatcham immobiliser,
I have access to another vehicle,
2 vehicles in the household.
Member of a vehicle club, LAndRover owners Series/90/110 Club.. denotes you care about your vehicle more than your average mondeo owner I guess.
Only me driving it.
I checked on
Insurance: Cheapest Car, Home, Travel, Van, Bike, Dental, Loan, Mortgage Insurance & more and they've got some really good tips.
What's the business, are you a beer guzzling hod-carrier or librarian etc..
If your vehicles sign written then some insurers feel that this will encourage you to drive better because you're representing a company/yourself.
Sign up for that 'is this vehicle driven well sticker', contact them here:
RoadSafe
I asked for fully comp because this demonstrates responsibility somehow!
If it's a start up you get big tax breaks for being new, how formal is it? One policy for social,domestic. and another limited mileage for the business from separate insurers maybe.
I'll be honest, my answers were 'open to interpretation' but nothing dishonest.
Keep trying, how about a local small business association/insurance brokers, they're working for themselves and like beating the big firms.
3rd party for a year then upgrade.
Maybe include a second named driver with a big NCB on their history, the average will still be less than you on your own?
Definitely check out MoneySavingExpert.com ins section.
And good luck, if you're doing a good thing then it will work out, keep going.
