Building regulations, chimneys, and indemnity insurance

Hello

I have quite a predicament and hope you can help? I bought a modernised ground floor flat back in 2004, as a leaseholder. It's part of a victorian converted building that was converted some twenty years ago. The modernisation of my flat was completed in 2004 by the freeholder of that time. The modernisation entailed a complete refit of my bathroom including plumbing, electrical work, tiling and replacement ceilings.

Over the last year a damp patch had started to develop in my bathrooom ceiling, the exterior of the building was painted and any holes filled but the patch remained. A surveyor then removed part of my bathroom ceiling to see if a pipe was leaking from upstairs. We discovered a hole that can be filled however the surveyor highlighted a chimney hearth protrusion so a second opinion was asked for. The outcome is that a structural engineer has confirmed that although safe the chimney protusion doesn't comply with building regs. He has recommended a steel is inserted to make safe.

The freehold was sold back in 2006 so is now owned by a different person to who completed the modernisation in the first place. The managing agent remains the same however.

I don't have indemnity insurance and wonder if I have any claim against the building insurance, new freeholder or managing agent, as mentioned I've been here since 2004?

Thanks in advance for any advice you can give.
