The house was built in the 1930's and has a proper working chimney! But, the concrete fireplace lintel sticks out a bit and I want it flush. Have asked a builder to come round for a quote but they said they couldn't provide a competitive price. I guess what I want to know is whether this is a tiny job, or something a bit more complex. My simple logic suggests that as it's sticking out about 10 cm, it can't be supporting anything, so can be easily removed.
