First time of growing broccoli we had brought from nursery and planted they have just not long got a head and have notice that there is little ones on the plant also from what I have been reading through that doesn't usually happen til after the main head has been cut but for some reason it is just wondering if this has happened to anybody else

My broccoli last year/this year were like that. My plants were way too big (too much Nitrogen) - all leaf and very little heads. Try planting after a crop that has used the N and if you have to, add a bit of fertiliser when the plants are half grown. A small amount.

Thanks for that I do put seasol on them every couple weeks as I have a few different things growing in the same area so it all gets done

If you prepare your ground before hand and have added compost/manure/fertiliser then the plants won't need any more feed while growing.

You should have picked them before they flowered.

You have left it too late. You pick before they flower.

Unless you live in a very bug and disease free area, most plants need regular attention. If grown in good soil and watered every few days broccoli will grow very well as long as you have no grubs. If you have grubs (from moths) - the plants may look great one day and a few days later the heart of the plant could be eaten out. That is the end of that crop/plant.
