    Default Electrics

    Is it bad that the first place I think to ask when I have questions I don't know the answer to is this forum?

    Anyway, I brought a new house not long back and the en-suite bath is a fucking mess. So anyway I have brought all the gear to get it done but I want to fiddle with a few things. Firstly I want to get rid of the existing light and put 4 downlights in. Reading up these look up to doing the job https://www.screwfix.com/p/lap-fixed...ails_container I think anyway...

    My second issue is that I want to move the position of the extractor fan on the interior without moving it on the exterior, can this be done? If you look at the picture it is currently head height in the middle of the wall and I want to move it up in to the corner for my new bathroom mirror. I've never took apart an extractor fan, but is it as easy as putting it up in the corner with ducting to the outer wall hole? I honestly haven't a clue. The extractor runs off the light switch, does this make it even more tricky?

    Lastly does anyone know a decent electrician and tiler in the Mansfield area .

    On the extractor fan, you will probably find it’s a „straight through“ duct, so it goes right directly outside.

    If so, to move it, you need to also drill through the wall onto the outside again, unless (in the unlikely event) that it’s ducted up into the ceiling (but it doesn’t look like it from that photo). It’s not as simple as making a „dog leg“ duct back into the existing hole, and that would not be optimal for the air flow anyway.

    The power is the easier part; the Fan will be wired into the ring main that powers the lights so it comes on whenever you put on the light switch. Changing the light fitting is straight forward enough, but if you’re not „Part P“ qualified then - „officially“ - you’ll need a sparky to sign off on the paperwork (of you don’t, that can be a ballache when you come to sell!)

    I think all bathroom works are notifiable, get an electrician, as there's a lot more rules and regs in bathrooms.

    A few things though, as Chris said, the extractor looks like it goes straight out the wall to the outside, if it does, it's a new hole and brick the old one up, the wiring can just be took out and chased to the new location, remember always go vertically (you can go Horizontal bu that shouldn't apply here) from the fitting with your wiring.

    As for downlights, be careful, I can't see what's under where you want them but a bathroom is divided in areas, where stricter rules apply above and around baths etc.
    Also, you're putting holes in your ceiling for steam to enter the cavity/void/loft, this can cause issues with damp, condensation and high humidity leading to to other problems, make sure they seal properly against the ceiling as the IP rating is for ingress into the unit, not the hole you drill.

    The fan will need to be moved externally also , Like Chris says it will be a straight , trying to reduct all that would mean cutting out loads of the internal wall to fit it.
    Just start again it would be less work unless there is a major problem with access outside .
    The downlights would be a piece if piss for any spark who would also move the fan.

    Also you may want to change it altogether, Mine is in the ceiling and is ducted out via the sofit , It really does depend on the whole set up position of the roof etc etc .

    I used to try and do electrics.
    I think with it being a bathroom (water + electricity = not a good mix if you get it wrong), I'd get a sparky to do the lot.

    Cheers lads, confirmed a lot of what I was thinking.

    The extractor is the pain in the arse but, the reason why it is low down is because the roof like outside I think. Theres still some room where I could move it up thought I think, or do as Lard suggested and put it in the ceiling and out.

    Fucking westerman homes who built it... sigh

    Get rid of the fan and put an electric actuator on the window.

    Yes think you have 3 bricks above the vent , I would personally just have it coming out of the sofit along the loft and back through the ceiling, Saves having to drill through the wall .

    Yeah that seems the best option, means I might be able to put a more powerful unit in too.

    You can get ones that incorporate a light over your bath/shower, up into the cueling then out either the soffit or a tile adaptor

    To move that fan you’ll need to drill through the wall a hole the diameter of duct, to do this I’d recommend hiring a diamond cutting core bit for your drill.

    I think you pay for the amount of wear to the diamond cutter, fuck knows how they measure it

    I used one at my house and gave up once I got through the outer bricks which took two hours, I took the kango to the inner layer of bricks. Old sherwood bricks, like bell metal.
    The duct is in my loft space with the extractor on the bathroom ceiling, so wasn’t a problem.

    Looking at them bricks at Gandalf’s house a decent core drill will go through them like butter.

    I LOVE this forum.

    Honestly. It's an education and all so helpful.

    I've picked up a lot of valuable information from all of the above.

    Lard's tool thread is also excellent for any budding DIYer or tradesman.

    Like you say, older house it can take hours & they snag like fuck

    For the light fitting you aren't actually 'changing' the circuit you're just changing the end device (1x lamp replaced with 4x smaller lamps). So you could take the existing cable in the loft and run it to the first new fitting then daisy chain from there to the other three.

    No need for a sparky then and the biggest problem is drilling the holes the right size, or at least it was for my plumber...

    Only those who will risk going too far can possibly find out how far one can go.

    It's in the bathroom and therefore, notifiable, legally.

    Or you know, do it yourself, if you're competent and "it was like that when I bought it"

    Here is a copy of the most recent Part P approved document.

    https://assets.publishing.service.go..._AD_P_2013.pdf


    In a nut shell it says that all electrical work carried out on domestic premises must comply with the most recent version of BS7671 otherwise known as the wiring regulation which is currently the 18th edition. It also informs you what needs to be notified to LABC.

    Basically its a load of bollocks because there has not been in the 14 years since its inception one person prosecuted for failure to notify any works, so make of that what you will*

    * I would recommend getting the services of a qualifies electrician to carry out the works, and notify it for you under Part P (if required) as this has been known to cause a sticking point in the future of people attempting to sell their house.

    Aye, ten years ago I’d be up a ladder core drilling for a few hours, avoid stuff like that now. I stick to specific carpentry and plastering work.

    I know, I'm Part P qualified along with Building Regs and various other C&G quals.

    The point is, if you aren't changing a circuit there's nothing to notify. Replacing the lamp isn't a change in itself.

    But daisy chaining extra lights in is, in bathrooms.

    I'd always recommend getting a fully qualified spark in, part p is looked at poorly by the trained sparks I know.

    I wouldn't say dont do it, if you feel comfortable and follow the regs but, as said above by a fully qualified sparky it can lead to problems when selling, we had similar issues selling our dads house.
