I work in Insurance, and not trying to put anyone off but when checking around always check the excess levels. I was informed by an advisor that NU Direct recently cancelled any link with InsureSupermarket motor quotes because they were obtaining quotes with 2 excess levels but under same quote reference.
Its also worth checking what any 'scrape' site includes. Many don't include courtesy car, protected no claims, or legal cover. These 'scrape' sites
(confused.com & insuresupermarket) obtain your info then just get basic prices for you but with varying excess. (
Normally you find the cheaper price but high excess at the top, but most people see a price and dont look at the cover)
Also, If a price is good, check what it will cost you during the policy term. Most brokers will add extra fee's for admin. This could be for duplicate certificates/paperwork, changing your details or missing a payment. It can vary from £10 to £25 a time!
I wont go into blowing my trumpet but most
direct companies will only charge you if there is a change to rating factors ie: Changing Car, or Address or Cover.
Finally, see if the online price is the same if you called up to accept it. There are some that penalise you for paying over the phone for an online quote. Lets face it, this may be 2006 but not everyone likes transmitting card details online.
At the end of the day, go for what you can afford but making sure you have the cover you need.
Its when you claim that you find how good your insurance company is !
