Insurance policies nowadays on renewal have to display prominently the current premium as well as the premium required to renew the policy.

I got a renewal letter recently that showed those two figures side by side. Old premium £37 odd, new premium £84 odd.

I rang, declared my dissatisfaction with a 220% increase and suggested a rethink.  After a bit of haggling I got a new offer of £44.67.

That's miles better but it's still a 20% increase for no good reason.
