The more time and research you put in to obtaining quotes, the more likely you are to get a better deal This is especially important if you are over 70 or under 25, and at the first year renewal when premiums can go up significantly.
If you have the time, get quotes from at least two comparison sites and use insurers and brokers that don’t feature on comparison sites. Remember, cheapest is not necessarily best. Get the right cover or your policy will not pay out when you need it.
