My brother will be starting an extension soon and he is considering
underfloor CH? Is it really as good as it claims to be?

I see various problems. The extension will be a bedroom with an ensuite
over his attatched garage.

1. He will be heating up the floorboards and probably a carpet before he
gets any heat, that must be a massive waste of energy. Would a good
quality wooden floor be better than a carpet?

A waste of time. He will be heating up a garage as well. Best he heavily
insulates the floor between bedroom and garage and make sure is it
air-tight.

Myson Kickspaces can fit under baths thyat heat your feet - towel rails too.

Yes, zone off the new extension.
