@Dartlec thanks a lot for info. Close up:

The mcbs I have have a slightly different model number 06156, but look identical from the front....

Can't find a definitive answer, but this link seems to suggest the the 03 and 06 ranges are directly compatible.

Assuming that, then the new RCBOs from CEF (DX3 range) will definitely fit - just tried them on a Tenby DIN Rail and the slots appear to line up for either style of busbar.

@Dartlec thanks a lot for going to that trouble. Much appreciated.

If I ever need to check if a replacement or additional MCB/RCD 'fits', I remove the bus bar and two of the original MCBs, then trial fit the new device onto the busbar with the other two devices each side. If they all stay nicely lined up when the screws are tightened, both in the front and the back, then it passes the test.
If no suitable device is available for this board, moving the MCB for the bathroom lights to the LH side of the board would be an acceptable, if not ideal, solution.

Thanks for that idea, hopefully it won't come to that, but always good to have a backup plan.
As it's a 3 storey house, I'd also need to check if there's a shower room on the top floor...and which circuit that lighting is on. I didn't have access to top floor today.
