I have been pressing on and sowing seeds but others have
told me that it is too early as we could get more frost more snow
and it's generally too cold.
My argument is when plants grow naturally they will drop there
seeds in the Autumn and they will lay on/in the ground all Winter
without coming to any harm and start to grow in the Spring.
So, does it really matter if I plant seeds and a bit of frost gets to them ?

Perhaps the thing to consider is whether the seeds you are planting are
native to this country, or a similar climate?

I can see carrots, turnips, onions, potatoes, broad beans, etc all being
fine. I can't imagine sweetcorn, pumpkins, french beans, tomatoes or
aubergines being too happy about a dose of spring frost.

Incidentally, I believe the last frost date for most of this country is in
approx 3 weeks. (how they work that out, I have no idea, but so I've been
told)
