Thanks for all the opinions guys,
We have s very large window in the living room which is floor to ceiling, so the girlfriend wanted to keep that feature lol, so couldn't run radiator under the window, hence this wall, and one opposite (near back boiler position so pipework isn't seen)
Just behind this wall in the picture is the stairs, so that's most likely why.
I'm torn as several people have said several things , I don't think I would get used to them showing as they are , and if they were boxed in and fitted then painted over etc then I could definitely love with that if chasing them in isn't recommended.
The gas pipe bothers me in the living room because it's just ugly and even if I painted it it still looks out of place to me, so I night look at boxing that in too.
I'll speak with plumber tomorrow and get his opinion
Thanks for all the advice
