Fill and skim cracks or replaster

[MartinB85]

Hey everyone,

Just looking for some advice on these cracks in our bedroom.
They were caused by steels going in on a ground floor extension so they were expected, however its been about 3 years so hopefully everything has settled.
The cracks go straight through to the brick.
The plaster doesn't sound loose around it but I'd rather prefer to fill and skim or remove the whole lot than just take of areas around the cracks.
Any advice would be great, cheers. (The rad with the crack going behind is been moved to a new wall so the whole crack will be fixed either way)

If the two plaster levels, either side of the crack, are level - then just scrape out a V, along the crack, and fill level.
