... I would think that the best approach would be to adopt a similar approach as with MOT tests. In other words, I think that (at least for the 'landlord reports') there probably should be a set of mandatory rules about 'coding' (within or supported by legislation) which are as comprehensive as is practicable, thereby minimising the (inevitably some) situations in which 'human expert judgement' was required.
You are aware aren't you just how much of the moT is down to the inspector's judgement ?
Yes, many things are simple yes or no - a light either works or it doesn't. But in the electrical world we have that - e.g. fault impedance is low enough to trip OCP or it isn't.
In the MoT there are items like "corrosion" where the inspector must make a judgement as to whether corrosion is insignificant, or warrants an advisory, or is serious enough for a fail. Similar with play in joints and bearings, judder and grab in the brakes, "visible" smoke in the exhaust, oil leaks, and ...
The main difference IMO is that the MoT business is heavily regulated, the inspectors have to undergo formal initial and ongoing training (where I suspect official guidance is given on making the above determinations), and the equipment is eye wateringly expensive. My local place put new gear in a few years ago - Mike did tell me what it cost, I don't recall now but it was definitely in "how much
" territory.
MoT stations are also now very tightly monitored. Apart from visits, the computer system now tracks statistics - and a few have been "told off" for (e.g.) just popping a new bulb in and passing a car instead of failing it and then replacing the bulb because the computer flagged up that their failure rate on bulbs was significantly below average.
Vs the electrical industry where the regs don't make sense, and the very organisations that should be providing the guidance have failed to do so. If those organisations did a bit of g.o.y.a. and produced some guidance, we'd be in a much better situation. But even so, another big difference between electrical inspections and MoTs is the variety of stuff to be inspected. All road vehicles share common characteristics, and even the way out and whacky don't really introduce all that much that's new. Pinning down the vast array of different electrical equipments and practices to a "simple" set of rules would be a Sisyphean task.
Crazy world we live in, I joined a Landlord forum to ask about this and it seems that technically my son would have been liable to a fine of up to £30,000; even if it was because the DNO decided not to expedite the repair; or if the tenant refused or delayed access.
Tenant refusing access is a simple one - the landlord is off the hook provided he can show that he took reasonable measures to comply, it's the same with gas safety checks BTW. And this did come up during the lockdown, when some tenants were in "no-one is coming into my house" mode. More complicated if your usual engineers are closed down (as ours were). The HSE weren't all that helpful with their advice on that one, only advising that you needed to have taken reasonable steps and documented that you could not find anyone to do it.
Should it come down to potential action over the DNO stuff - which most think is highly unlikely as councils don't use the other legislation they have available, and don't have the budget for the manpower to do so. The landlord's defence would be to have reported it, and point out that legally there is nothing in the landlord's power to have the repairs done should the DNO not attend in a reasonable time. Not being legally allowed to do something ought to be a defence against a prosecution for not doing it !
Only now, there is also an opportunity for unscrupulous companies to take advantage of the legislation. My son was quoted £1100 to rectify the "urgent" issues and provide an EICR, with the quote highlighting the law, the deadline, and the very high fines involved. When we asked for a breakdown of the costs, it included a whole new consumer unit - blatantly dishonest of course since that was coded C3 - and massively overkill IMHO (even if it is plastic) on a house about 12 years old. Fortunately I was able to advise him otherwise and we used a different electrician!
That's nothing new, the charlatans crawled out of the swamp to take advantage of "Part P" in 2005 - some of us have been predicting a similar wave of dishonesty over this.
BTW - as the firm was being dishonest, did you report them both to their scam (I assume they were a member of one of the schemes) and trading standards ? This needs to be done, it's the only way they'll be curtailed in their dishonesty.
EDIT: It would help if agents were better educated as well. As it is, it's easy to just swallow the "carefully worded" information put out by vested interests (i.e. the scams) and then incorrectly advise landlords. I got an email from our agent telling me what I
HAD to do. I tore it to shreds and pointed out five factual errors in just two sentences - I didn't get a reply to that email
