Are these plasterboard cracks in ceiling?

[FrankieStaff]

Hi there,

Just wanted some advice. From googling lots, I think the cracks we have in the ceiling above our stairs/landing are just the plasterboard joints? If anyone can confirm this and am I right in thinking I use joint tape and plaster to fix them?

Yes, they're on the pb joints. Any new works in loft? Boarding a loft creates this kind of damage as extra weight creates movement on old timbers
