They're pretty hardy plants but personally I'd wait until March to sow them as later-sown plants will catch up with them and nay not succumb to any really cold weather.

I would never contemplate sowing brassicas indoors, it's far too warm for them. You just end up with weak plants. It's very early to be sowing yet and as said, they will soon catch up. I may make an early sowing of a fast maturing cabbage to get a crop in, but that will be in a greenhouse that, whilst heated, is only set to be frost free.

Plus, broccoli (really it's calabrese unless it sprouting broccoli) is less hardy than cabbage. It doesn't usually get sown until the end of March, so it's not too cold when sown or planted out
