You might want to suggest that - but I certainly didn't, and wouldn't!So the fact that very few if any cases have been taken to court, that allows it to be considered okay to continue installing systems that have not been proved to be safe and documented as so?
On the contrary, whilst pointing out that we can but speculate about how courts would behave (becausethere have been so few cases), I said that I believe a court would probably usually look for compliance with BS7671 as an indicator of compliance with Part P (unless, very rarely, someone produced an expert argument that work was compliant with Part P, although not fully compliant with BS7671).
