How do I know if Building regulations apply?

[Shelle]

Have checked some websites but cannot determine whether we are affected or not.

Last week our water tank exploded and consequently flooded a part of the loft and collasped half of the landing ceiling. A plumber replaced some pipings etc to stop the leaks. Due to asbestos being found in the ceiling, the entire ceiling is being taken down and then a new on plastered on. Does any of this work need to comply with the building regulations? Ironically just before this happened we were also looking into a new loft hatch and ladder being installed in the landing (on the opposide side to the new hole!!) and flooring put in. Whilst I would not call this a loft conversion, does it need to comply?

Also realised that while looking at new fires it might be affected. We already have a balanced flue fire installed, and are looking to replace it with a new power flue fire. Does this also need to comply?

The websites dont seem to be too clear about the smaller jobs so I hope you dont mind my asking you on here! There is always someone who knows the answer hence why we post on here!!

Building Regulations are there to set minimum standards of safety, health and comfort in properties. You don't need to worry about them when plastering a ceiling, nor for installing a loft ladder. Its only when one converts the loft into a habitable room that BR applies. There are constraints on the position of flues in BR, but you already have a balanced flue, which would have been installed correctly. Suggest you ask the supplier of power flue fires about Regulations - as far as I know you can just use the same flue arrangement.
