Good in theory. Unfortunately, qualified doesn’t always mean competent.

And how often do I check the paper before it dries out in my airing cupboard next to my hot water cylinder?Drape a piece of toilet paper across it.
If you draw some lines on the paper using water soluble ink then if it does get wet the lines will become blurred and remain so when the paper dries out

Think about it... You're missing something!

Firstly thanks for all the replies, very useful.
Secondly, please don't call me an idiot. I'm not an idiot.
Thirdly, are you really saying that I can't legally do ANY of this work myself? Can't remove the old tank, or put the new one on the wall, or wire it up, or anything else which doesn't involve connecting up the pipework?
Again, any replies appreciated.

Yes you can remove the old one & probably fix the new one to the wall. But it'll save you buttons on what you have to pay the installer & open you up to blame shifting if anything goes wrong
I have on large industrial engines not on test beds, but in real locations, one of our engineers had a very narrow and lucky escape when he was running a fire pump engine and the viscous fluid damper failed took out the timing cover and gears and a piston and rod came flying out from the crankcase at quite some rate of knots.
We now equip our engineers with baseball gloves to catch the parts...
Also I've seen a 600kg turbo charger blown of its feet when the engine failed to start because some dickhead turned off the pre-heaters, the turbo and exhaust system was filled with unburnt fuel, when it did eventually ignite KaBOOM.
My point is if something has the potential to be dangerous it's best to be wary of the consequences, always er on the side of what if
I didn't call you an idiot. I said when things go wrong it could be the result of an idiot having done the installation.
Yes of course you can, though anything to do with or connected to the unvented cylinder must be installed by the qualified engineer. Anything else can be done by yourself, if you really want to. As suggested though, anything you do would not normally be covered by your engineer.
No unfortunately you can't, the tundish must be sited close to the cylinder and then on a continuous fall to the outflow.
Ok, thanks. I guess the tank can't go on the ground floor then as there is no way to get to the outside with a fall on the outlet unless there is a way to pump it. But do I need a tundish if the outflow is visible from outside the house, for example a pipe stopping short of a gully?

Yes a tundish is required within a certain distance from the cylinder. No it can't be pumped, D1 & D2 needs to flow under gravity to the waste/soil/gulley.
Sorry .... your 'read more' link only links to this post.
