Early spring is a good time if the weather's not freezing the soil! You'll need to sow it quite thickly as the birds will try to eat it. One way of stopping this is to use chicken wire over the top.

Here in West London, I wouldn't put down grass seed much before March - it's too cold to germinate before that, although if, like Spritzhenry, you're in the west of the country, doing it now may be okay.

I agree - I wouldn't really call February 'early spring', Bamboo - I should have said 'March'. Sorry, Tethington.
