Thanks All.

On the matter of the power, the potential difficulty in using a 3.5+KW
machine with a regular extension lead was my main concern. If a 1.7KW is
up to the job of dealing with most DIY breaking tasks, then I will
probably stick with that.

With regard SDS, SDS Max etc.- yes, I think I used the wrong term. It's
a hex shank breaker that I'm after.

As John says, weight is a problem if you were attacking a substantial
wall or the side of a big concrete block, but you could suspend it from
a tripod or A frame. For breaking a slab, you are relying on the weight
and don't have to support it yourself.

But isn't the best way to do a wall (unless it is a reinforced concrete
motorway or something) to stitch drill a block,[1] and then use a
moderately large but easily held jackhammer to break the mortar bonds
block by block?

[1]If knocking out a block with a big hammer is too destructive or
ineffective.
