I was surprised at a relatively cheap quote this year. With mods decalred through Flux I'm paying £550. I ran a comparethemarket to see what I'd get without the (very small number) of mods, and it was £350. All cheaper than last year.
For context I'm 36, have about 14years NCB, an SP30 to declare, but live in a BD (bradford) postcode, albiet in a nice area the BD prefix puts the price up. Greenlight wouldn't even quote me.
