UK Job quotes vs DIY Part P Notification Requirements for bathrooms

[timhoward]

Before September last year anyone who'd done a 6 week course and gotten their Level 3 was being accepted onto the schemes. Basically you could have gone to a training provider, coughed up around £5k, done a 6 week course with no prior knowledge and then straight out to join the scheme

It was even worse than that, bs7671 18th edition exam and two years experience and you were in as a DI.

The rules, i believe, have just changed to make it a lot harder to join. No more 'domestic installer' course graduates are eligible to join the schemes, as far as i'm aware. However it may be the case that those who did a domestic installer course and are already registered might be able to carry on their membership.

Yes, now even some decent sparks can’t get in very easily if they have long standing experience as opposed to bits of paper. Once in you can stay in.

The whole thing is nuts, particularly given most customers don’t even know they need the vague and almost useless bit of paper that we spend hundreds each year to have the ability to issue.

£180 for a haircut?!?! Is that a typo?

Cut dye and blow dry...it's a dear do being a woman.

I'll do it for £1.80

My petrol leaf blower will have it dry in a couple of seconds!

Just to update this thread since you were all so helpful.

We were left up the creek without a paddle as unfortunately the electrician we had coming fell ill and couldn't come for at least another week. I considered contacting the chap from the forum as suggested, but we were going to end up putting the bathroom fitters off for a 3rd time if we did so.

In the end, we decided to remove the shaver socket from the installation and stick to items that I believe all fall outside of Part P notification requirements. Also, we were replacing items rather than creating new circuits, unless I've misunderstood the meaning of a "new circuit".

I did as suggested and purchased a voltage and continuity tester as well as a voltage detection pen type device, both made by Fluke.

It all works, on the suface at least, although I realise that's no guarantee it's entirely correct/safe. Having said that, I'm confident in whats been done.

During the work I found a cable which had been damaged during demolitions presumably and the bare earth was visible, so that was a good find.

I was thinking about putting up a separate thread about the work performed and asking for feedback, but not sure if this is allowed but surely you all enjoy a good chuckle?

Thanks again everyone.

We like pictures, be warned, you are likely to get honest an honest review!!

Wouldn't be much use if it wasn't! When it comes to electrics and plumbing, if I have messed up I'd rather know about it. Not a fan of fire or flooding lol. I just appreciate the feedback, I really do.

Here's the current state of my wiring. I hope I wired it correctly. The floating brown wire was awaiting connection to common live in the double switch (now done). The FCU is serving only the extractor fan (class 2) and is fused at 3amps. Flex is due to fan having flex retainers.

The double switch serves a junction box, to which is connected 3 LED drivers, 1 driver per light fitting, which are 8.7W 500mA, IP44. The second switch is for mood lighting at a later date, so is presently terminated into a debox in the loft space.

I've run brand new cable everywhere, it's all 1mm, except the flex, which annoyingly is a rather portly 1.5mm as Screwfix were out of 1mm 2 core flex. Tried to label everything up so we didnt get confused.

Like the MK stuff, but the terminal screws were super tight and they aren't particularly aesthetic. Hoping to upgrade to Hamilton at some point, budget permitting.

I'll take some more pictures when we start fixing everything down. Quite a few floating junction boxes at the moment whilst we fix the cables.

One question I did have was whether or not it would be acceptable to permanently join the supply for this lighting radial using a debox, or whether there is a better, more long term solution. The supply was simply too short for any work to be carried out so we've had to join it.

Many thanks.

Have to say until that photo I have never seen or come across a dry lining box installed before the plasterboard.

PS I like that you have labelled every cable. One thing on that I'd do would be to have the label inside the dry lining box so it's still there for future reference.

PPS Why flex cable for the fan?

In all honesty, whilst I wish I could claim I'd invented an entirely new installation technique on my first attempt. In reality it was because I hadn't a clue how long (short) to trim the cables to fit, so I thought I'd better put everything in situ to avoid problems later. It will all be taken off for boarding over the stud work but at least the cables will have found their shape, so to speak and fortunately it did fit, just, and without too much pressure on the connections.

The run to that backbox was difficult. Being on the 3rd floor (eaves), I had to take it on the underside of the paper backed insulation, which has battens. This is above the studwork top plate. It was fiddly for a first timer like me. Ended up using 25mm conduit as a precaution against studwork screws and/or later work and to avoid the cables moving outside of the permitted zones, especially the flex. All that added to this afternoons drama but I did find out that a PEX pipe cutter does a decent job on conduit.

I will move the labels yes, had them labelled for the pull through but as you say, would be useful to have them in the backbox itself, or just slightly above.

How much slack is it normal to leave? Or is that literally a case of "how long is a piece of cable"?

Flex cable for the fan because it has a round punch out on a rubber grommet as a cable entry point, then a rounded clamp further inside the termination housing (terminology?). It's not perfect. I found flex annoying to work with. All the strands, a real faff for someone as cack handed as me, especially into tiny terminals, but it being 1.5mm didnt help with the terminals clearly being designed for 1mm.

We talked at home tonight and I think we are going to rewire all the flex to the fan and LED drivers as 1mm (assuming proper cable spec), and use some little crimpy things on the ends, to effectively turn the multi strand into solid wire at the termination. If you know the name of those little bits of copper and what I need to crimp them down, I'm all ears!

Decent enough set for very little money - just make sure crimps are secure.
