I’m looking to buy some PVC Conduit for some security lights rather than clip the cable. We don’t use it in work. But I know I need 20mm conduit but would I be okay using 20mm inspection elbows? I assume they just fit inside?

No the tube fits inside the fittings and Don't forget to use the adhesive!!!!!

I’ve been given a length of 20mm PVC so I would need 25mm fittings.

No, 20mm fittings are designed, for 20mm conduit, you may need a bending spring as well as a tube cutter if you are doing a lot of tube work, although a Junior Hacksaw will do the job just as well, although a cutter makes a better job of cutting use Heavy duty tube it's easier to bend and work with. In my considerable experience. Light duty tube tends to kink when bending,

I would avoid manufactured bends and elbows they look terrible in any instance. Get a bending spring and use sets wherever possible and use BESA boxes as opposed to the fittings you suggest.

Okay that’s what I’ve got. 20mm fixings, inspection bends and elbows. Looks like I will need some adhesive.
Yep and saddles, box lids and screws and if outside some waterproof gaskets,

The inspection bends do not allow a cable draw tape to push around the bend without taking off the face plate or perseverance, better to use a slow bend or as suggested above a bending spring to get a slow change of direction.

Yes and black conduit for outside. Plus if it's a long run, expansion coupler.
