"The units themself can be procured cheaply but its important to put forward a realistic cost for this. The system will need to be installed by an approved electrician with experience in emergency lighting and they must be capable of commisioning and certifying the system to BS 5266.
It's likely the cost will be in the latter. Don't get me wrong this shouldn't be substantial but lets be clear its not just the cost of the fittings."
Regardless it's a stautory duty...
Agree, my point was that the fittings and electrician shouldn't be that expensive, and as such, acceptance that it was something they may want to do could be a relatively easy win, given that although electricians can cost fortunes, the task shouldn't be overly arduous, it's a question of desire.
we have had similar discussions on the extent of how far to go with emergency lighting and it does add up, however a phased/prioritised approach could help.
it also puts it in the category of do I want to have an arguement about this or spend time on it/are other things more important? - what are triggers to get to just do it please? and indicating that a reminder about it could help.
It seems both sides are stuck. I was proposing a way to get a discussion going towards how can we get this to work with someone who perhaps needs to reflect on the issue in order to get to a yes, (as I generally would).
getting the relevant guidance out for a discussion may also help. and discussion of why/what the barriers are to getting it to a yes, perhaps a discussion in collaboration with the landlord as the em lights could be transferred over to them when the garage moves so they aren't paying to put in and paying to take out, (or it could be retesting of whole fixed wiring because they haven't been done for ages, (again free maintenance issue with landlord) that will probably be best solved with a chat and a beer/wine, (or providing fittings for them to have wired in & associated contribution for electrician's time)?
The issue doesn't seem to be the lights as such, and by providing a method to get them you would trigger a discussion on the underlying issues and timing associated (which may be excluded from), but at least it's a start towards trying to resolve the issue, which seemed to be where it was actually trying to get to rather than just stating "there's a duty must do x". seems the why's and how's could to be explored further.
only an opinion.
