If you're working and you're the main breadwinner or income earner for your family, you need have some protection or insurance for the money that you bring. What would you do if you lost your job or couldn't work? How would you pay your bills and feed your family? If you don't have much in savings, you could end up with a serious financial problem very quickly. If you have income protection insurance, you can be much safer and have a lot more peace of mind, even if you do end up losing your income for some reason.
There are all kinds of ways that a person can lose his income and get an income protection quote for insurance well before you have any income problems. You need to get a quote from several different places because a lot of quotes are different, depending on the insurance company you work and the specifics of your particular situation. You can't expect all of the income protection cover options to be exactly the same that they offer and the coverage that you can get for that price. It's very important to keep that in mind, because you'll want to get the best coverage for your situation.
