Artex ceiling replacement - Plastering job in Neston

To access a leaking central heating pipe. an emergency plumber has had to create two access holes in my kitchen ceiling (artexed). The ceiling is soaked and the light fitting in the centre is drying out. The plumber has advised the ceiling needs replacing rather than patching up the two holes. It may be only half the ceiling that may needs replacing but I need expert advice first. I have formally made a claim with my insurance company and now need at least two quotes for the work.
