Just had a sketch of a structural engineer showing a u/beam bolted to the padstones with 4 m10 bolts at either end. Anyone come across this before? The wall is single skin so the padstone is only 120mm wide, dont fancy drilling 4 holes in each one.

If casting your own pads you could build the studs in.
If drilling start with the smallest masonry bit you can find. This will give you pinpoint accuracy which is essential, as you'll only have about 3mm tolerance. Once the pilot hole is there, keep drilling out the hole with progressively larger bits until you get to 10mm (which to be honest is sod all really)
Once the first hole is in, the rest will go in very easily and without stress on the concrete, as the bit will just be scraping away the edges of the hole.

this certainly isn't common, as most steels i have come across simply rest upon the padstones. is there an issue of restraint that this steel beam needs to address?

Ive not heard of it before either, as you say we have always sat the steel on the padstones. Nothing unusual about the steel or its positioning, just a normal knock through to open up a dining room/ kitchen, 2.4 metres wide opening. Thought it might have been some new regs i hadn't heard about.
Have you asked your engineer?
I agree, this isn't common. I came across this for the first time recently. I asked the engineer if it was necessary. He said; well, not strictly necessary but it's always better. So I asked if it would be a problem if we didn't do it. He says; if it's easy do it, if it's a hassle don't. So we didn't
