From your single photo it is impossible to determine circuit type or cable size, therefore impossible to advise a course of action. Can I suggest, and I'm assuming you have a suitable method of proving the circuit dead, and that the existing connected microwave has at least a light or similar still working on it.

1. Trun on microwave so light or clock is on.
2. Turn off breakers/remove consumer unit fuses until said light/clock on microwave goes out. Leave this off/out. I presume under your control so nobody else can turn back on??
3. Remove lid of junction box. Don't stick fingers in. Test dead. Take photo of internals.
4. Note cable sizes, the grey ones will have it moulded onto them.
5. Make a note of what else has also gone off as a result of pulling fuse.
6. Come back to this thread with more info...

Has it?

Although it made a bid for freedom through my arms and leg, I couldn't remove it because it's hardwired into that junction box.

It's back in place and yes it has lights on. The reason I'm removing it is because although the clock and lights are on, when you programme it and press start...nothing happens.

The kitchen is on a seperate circuit (at least I believe so because we have a seperate fuse for it). That handles the microwave, oven, the lights in the kitchen cooker unit and the plug for the fridge. But not the ceiling lights.

I could do as you say but I need another guy to help me with the microwave - it's about three or four times the weight of the one I'm putting in.

Is any of this needed before I get an electrician in? It seems like installing another plug as suggested is the way forward.

From the way this discussion has gone, I would say my idea of the plug socket will get you up and running, but I'd get the whole room checked out just to be sure.

Sounds like your junction box is a spur off the kitchen ring then. Pull the fuse, remove the microwave wiring, add a surface mount socket, fit new microwave. If you get an electrician in then it will likely be covered under a Minor Works Certificate.

Phase 1 of shreddys plan achieved!

1. Trun on microwave so light or clock is on.
2. Turn off breakers/remove consumer unit fuses until said light/clock on microwave goes out. Leave this off/out. I presume under your control so nobody else can turn back on??
3. Remove lid of junction box. Don't stick fingers in. Test dead. Take photo of internals.

"Test dead."
I have one of these I've been meaning to unwrap and use:

Don't cut the plug off the microwave, it will just void your warrenty. Is the microwave the only thing coming out of the bodge box? I can't see from the photo. If so buy a 3 pin flying socket and replace the bodge box.

I would however question the wiring of the entire kitchen looking at that, you don't know what other nasties are hiding.

Can't seem to find a "flying socket" at screwfix, donthey have other names?
