Hi,
I’d like to have a switch at the bedroom door which will switch both bedside wall lights off or on with individual light switches each side of the bed which will switch on/off the light above.

I’ve tried to explain this in an email to an electrician who is quoting for work but have failed to convey what I want as I don’t know what correct terms are I won’t be at the house when he comes over to quote.

It's two way switching, or two way and intermediate to switch from more than one position.

It's common to have the centre light switched from the door and both sides of the bed, and then bedside wall lights switched either just at each side of the bed, or also from the door.

So you would have the centre light 2 way and intermediate switched (3 positions) and the wall lights 2 way switched (each). a 3 gang switch at the door, and 2 2 gang switches at the bed.

If you use Click Mini-grid, you can have an intermediate switch mixed with the 2 way switches.
