Kev lives near me so I pm’d my phone number. I find it easier to talk than type!
Changing the bearing is quite straight forward if you have a decent hydraulic press, which I have.
Sorry it wasn’t more interesting?

Good point though! I've learned a lot from the forum.
I'll take a few pics and post them. Might help someone.

We did it yesterday. Many thanks to Chris for his help.
Here are the pics I took before my phone ran out of battery. They don't show too much, but the image of the hub in the hydraulic press is useful to show how much of a pain that step is. It's very difficult to support the hub in the press. Everything else is very straight forwards, apart from wrestling with the circlips that sit either side of the bearing, and which, like all circlips, are evil and determined to wriggle away from where you want them to go.

A few more pics from the "operation"
As Kev said, the most difficult part was pressing out the wheel flange. There isn't a flat surface available that allows enough clearance.
For reference, the complete assembly consists of the upright itself which has the bearing pressed into it, the wheel flange is pressed into the bearing and the stub axle keeps it all together with a large nut.
Pressing out the wheel flange.
Pressing the old bearing out.
New bearing in.
Wheel flange back in.
The stub axle then just slides back onto the splines and the nut goes on last. The nut needs a huge torque so this is easier done when the whole thing is back together and you have a willing accomplice to heave on the foot brake .........
