Yup I got a call from Kwik Fit insurance once and though yeh why not I'll give them a try. Thinking brokers they will give me a quote like any other, wrong, they are a call centre that connect you through to some random insurance company/broker and you end up in the normal call queue, though maybe you get a direct line to a person, wrong. And yes you guessed it one was Allen & Allen "specialise in modified and imports" I was told. Effin useless.
Kwik Fit tries again last year and I told them "get me straight though to a person and I will give you one more try". "Yes Sir no problem, we have number of companies that can help", "who are they" I ask?, well the list was the usual list of brokers Adrian Flux ............... and Allen & Allen! "Forget it pal, In can phone them all direct and cut out your commission on the brokers commission on the underwriters quote.
Sorry rant over :D
Anyway there is only one way to get the premium down and that's to take on a higher voluntary excess then be sure that you don't hit anything as you get the bill. You could try TPF&T but probably no good as the risk is the damage that you may cause not the damage to your car.
