Adaptable box with front entry.

If I absolutely couldn't go underground with SWA, then catenary wire the other side of the gate might be worth a ponder.

If you stick with conduit following the route shown on the photos, I'm not following why you would choose to put them in that exact position or why they are in fact needed. Sorry if I'm missing something.

So it will follow the same route down the house but where the bend is I’m looking to replace it with a Wiska or adaptable box then go straight across. As the arch is going and a new gate in its place. There will be another box on the right, on top of the wall. Then across into the garage.

Agree I wouldn't persist with the conduit. Adaptable box on the house and change to swa.

It’s not possible to change to SWA as both rooms have been decorated.

10mm² t/e? In 20mm conduit?

Looks like 25.0.

Could be. Even so, it will be a struggle getting around the bends.

If you are planning running plastic conduit unsupported across the gateway, as it is now, then, as it does now, it will sag.

Dome covers on conduit boxes solves the original question, but not the problem.

You change it externally at an adaptable box on the wall.

That's what I had in mind, yes.
Depending on aesthetics of new gate, catenary wire would get it safely across, cleat to outside of garage, then into another box to terminate and revert to T+E.
If it were my house I'd lift the paving and get it underground and out of the way even if I needed to mix some mortar and sort out the paving afterwards.
Anyway, best of luck with it however you do it.

As above , a better job underground.

How do you mean sorry?
