I've just taken a policy out with Greenlight, the guys I've spoken to demonstrate a good understanding of what they're insuring and also mods, literally a breath of fresh air speaking to Neil and his colleagues.
Business cover isn't an issue, future mods are added free of charge so long as they don't increase the cars power output and those that do are priced fairly.
Also UK track day cover can be added on an event basis with a small charge.
So with mods, 16yrs ncb and business cover included the policy came in at £436, with windscreen cover, protected ncb and courtesy car.
A bit more than Adrian Flux however I'm a believer in you get what you pay for.....
Now to negotiate my refund from Flux, as they seem to be deducting over 2/3 of my premium when the policy duration was only 1/3 spent all because they can't meet the customers needs....
Also after many hours on the phone the recommended company's above either couldn't compete with Greenlight or failed to make the effort to call back with a price....
