It depends.
Are your bosses paying you X amount because they don't want to pay more, or because that's genuinely all they can afford?
if it's the former, you have to decide whether you could improve their income by taking them some marketing ideas or bringing in more custom, or something. They might appreciate your input.
If it's the latter, show them what your position is actually worth, and ask them to review your salary.

EDIT: actually, that's the wrong way round, isn't it? Sorry, I'm stressed. My brain stopped working about an hour and a half ago.

I'm pretty sure it's not a money thing for them, the department is growing bigger and bigger, and there is lots of heavy expansion.

Then they must be taking the piss a bit.
If you're on what, 60% of the salary that you should be then there's nothing keeping you there.

Their loss if you move.

I see what you mean, but I love the job, and they're very good to me with my illness stuff... that I do all my work, but I walk in at 12 and leave at 18, when my hours are 8:30-17
But I do a lot on the weekend.

I don't think they're taking the piss, it's more like, I haven't bought it up and my 3-month review hasn't happened for 6 months.

You do need to push it
I bet their management meetings have a risk action about you leaving/asking for a raise.
