As far as I'm aware it is perfectly legal to use a dado head in the UK as long as it's for private use and not commercially other wise companies selling them would be in trouble, I have a Delta Unisaw and use a Freud dado set and it works really well but it does take a little time to set up probably as long as a router table but what I will say is it's a lot quicker than a router if you have a fair bit of trenching to do I can do a 2" trench in oak 1/2" wide in one pass try that with a router!
A dado is only as dangerous as the operator using it!
