Could be, but as I mentioned, the first told her she needed the whole place rewiring and she simply can't afford it. It doesn't look like it needs a full rewire as despite some dodgy bits which are more down to implementation and a lack of understanding, the bits I have seen of the installation seem to be in good condition, but I've not tested any of it yet and that could of course find a whole raft of issues. The second one, unless she's spinning me a yarn, did her out of a significant portion of her budget.
As for being short of work, I'm a fledgling business and I'm no where near capacity yet so I'm not in a rush to turn down work but at the same time, I'm not in a rush to get in over my head and get myself burned which is why I'm kind of bouncing stuff around on here to you guys who are far more experienced than me. My gut feeling is that because her English is poor and she's not a native some people have tried (and it appears succeeded) to take advantage of her. And yes, the idea of walking away had crossed my mind, but only from the perspective of I don't want to get in over my head in terms of any rules and regulations (like the emergency lighting and the fire alarm). On the practical level it's a fairly straightforward installation, the largest I've been asked to work on thus far for sure, but still relatively simple compared to say the installations in some of the offices I've spent a large portion of my adult life in.
From a business perspective, it would be much easier to go in there all guns blazing "it's all s**t rewire it" and charge her an arm and a leg for the privilege. The problem is if she's not got the money to do that nothing will change. I'm just trying to put some thought into how to improve it incrementally on a limited budget without limiting the options for future improvement and without spending money on stuff that could actually be temporary as a result of improvement in the future.
Aside from some small items (like accessories that need replacing due to damage), the biggest safety issues are the fact the main supply cable is T+E, runs more than 3m with no overcurrent protection at the origin and is possibly too small, there is limited RCD protection and the poor state of the emergency lighting which I'm looking in to.
Anyhow, thanks for all the comments and suggestions on the original question. Defo the best bet is a call to building control, I'm going to start with a 'what if' scenario and ask a few questions about what would happen if they didn't know it was a hotel and see where we go from there. I'll post an update about the dwelling/not a dwelling situation when I have an answer from my LABC. The rest of it, comments and thoughts are welcomed
Thanks all
