Is this as serious as i suspect?

Morning everyone,

Just re-plastering a room and was greeted with this lovely crack,

It is the rear of the house above some double doors leading into our conservatory.

I therefore checked above said conservatory doors and noticed that at either end of the doors there are very similar cracks.

Thecracks above the door are on the 2nd vertical brick in forom each end.

In the bedroom ive knocked some plaster away and it certainly goes into the blocks behnind (no cracks externally). Notice it also seems to have fallen away into the room 1-2mm.

Your thoughts?

Thankyou, royce

Internal crack behind rad. is probably long-term, probably due to initial shrinkage of blockwork - not unusual and rarely a structural issue. Just fill it.

Crack above patio doors is the usual problem caused by replacing old timber windows with PVC, in the absence of any lintel over the outer skin.
Retro-fit an angle lintel over the outer skin.

Just a way of describing it I suppose. If it's an older house (say before 1960s) there would often be separate lintels for each skin. Either a concrete (or timber - if older house) lintel supporting the inner skin, and quite often the outer skin would be supported directly off the frame (or sometimes an angle iron).
When I said 'over the outer skin' I meant 'bridging over the opening in the outer skin'.
(Sorry if it sounds convoluted!).
