Help! My scones won't rise.

I made scones for DH last week, and I made half fruit and half savoury, but neither rose very much.

After trying both, he's decided he just loves the savoury ones, and wants me to make more, so I made a new batch yesterday but they still didn't rise.

I use top quality flour, and sift it to get the air in, then rub the butter in well to add more air. I then put them in a hot oven to cook them quickly... but alas, they still didn't rise!

I didn't use the cream and soda recipe, but made them from scratch.

Any suggestions?
