No wonder they didn't do the job properly- that concrete will be fun to remove.

yep, my thoughts exactly. Sounds like the chimney was a beast too, I guess it got to home time Friday and they decided to screed over and run! I'll get through it, it might take some time, but it will go. The big stones make it easier, I just aim my sds at those a wiggle until it comes loose, then repeat. Slow, painful work.

Removed floorboard to about half way, and woodworm much less now. Hopefully this is enough. Plan is to remove all board on chimney side, then lift the rest, treat with Everbuild LJUN05 5 Litre Lumberjack Triple Action Wood Treatment, along will all joists (the one near wall needs replacing) and put in new board. Oh, and insulate first.

A 2kg hammer drill might take some time and you could weaken the fender wall.
A club/sledge hammer and bolster(or a demolition drill) would be quicker unless you want to preserve the existing fender wall. If so you will still need to remove and replace the wall plate to prevent damp rising from beneath it through to the (new) joists.
I would be tempted to take the whole lot out. This would involve new sleeper walls, also properly protected from damp below. You could then extend the insulation across the old hearth area.

my plan is to insulate everywhere, although I am thinking that my skills/tools combo might mean I only insulate with 25mm board over the hearth, which should be enough to stop condensation issues.
Is the fender wall the one that the first wall plate (is that what its called) sits on, are is this another wall?

If I fail to get rid of all that concrete but say, remove 50mm, what would be best:
1. Put in 25mm solid insulation under the floor, leaving a 25mm air flow gap
2. Fill with 50mm rockwool insulation
Is there a risk of rockwall getting damp? I am going to improve ventilation as much as possible - probably 1 or 2 new air bricks.

Most out to bottom of joist level . One cleaned up i should be able to drop some new joists across, insulate and board.
Those darker red bricks bottom right, is that a sign that they carry more moisture? Could be the damp cause, as they are in contact with joists etc below damp course?

You're getting there.
It's not uncommon for the dpc to be bridged because the outside ground level (the driveway in your case) is above the dpc within the brickwork of the house. In fact it should be about two bricks above the dpc as rain etc splashes back up onto the wall.
Not of direct concern regarding the hearth removal but worth checking.
OOI how old is the property?
