Q.Is My Holly Tree OK
I’ve a old (taller than the semi) holly tree on the street boarder of my back garden. Thankfully the kids have grown up and so the problem of old leaves pricking tender feet and puncturing swimming pools are past. But I guess the growing crop of grand-kids will reignite that quite soon. This year it is only just now there are few real signs of new leaves coming. At the tips at first and then back towards the trunk as normal but it seems somewhat late and rather slower than previous years. Happy to be told it is me that wrong but might it be something else ?

Unfortunately, your photo did not come through. It could be that they need a little fertilization, compost, or mulch added to bring them back to health. They aren't very picky, so bringing them back is not usually a big ordeal.
Sometimes, a little pruning can help, as well.
