You could box the supply in as said above.
You could also get the rest above it boxed in but the CU (consumer unit = fuse box) looks old-ish and pretty tight fit up there top-right. If you are thinking of boxing in the top area you might want to look at the last EICR (electrical installation condition report) and consider if it will be replaced any time soon. If so it might be better to move it down and left on to the wood with all of the stickers as marginally more accessible should you need to reset anything. Sort anything like that out before you get any joinery work done.
Moving everything down to an easy height for access, specially if anyone with wheelchair needs have to be consider, is also possible but more involved. The DNO (electrical supply utility) could move (realistically put in a new) cutout further down, and have the isolator switch and meter lowered. Then your electrician could put in a new CU lower down with cables extended down.
That might also involve boxed in cables running down the right hand side, maybe in trunking, but depending on the type of wall (e.g. if plasterboard over beams, etc) it might be feasible to run cables down behind things to allow the wall to be all clear from waist height upwards.
