    High earth impedance

    Yes, with an earth rod. Is the high resistance still an issue with a modern RCD? According to the wiki page on earthing types, the distributor is obliged to provide a TN-C-S or TN-S supply if requested and available; assuming this doesn't only apply to new installations, is this worth...

    High earth impedance

    The issue has been investigated by another electrician and..... it's a TT system! As mentioned above the electrician stated that an impedance of up to 200Ω is acceptable. Thanks all for your advice, had it actually been TN-S this advice could have made all the difference... If...

    High earth impedance

    He stated that the gas meter isn't currently bonded, so presumably not being used as the earth (the two meters are co-located)? The water supply comes in on the opposite side of the property, he said he couldn't establish whether it was bonded or not (there's no meter). It sounds like you'd...

    High earth impedance

    And also a member of the Electrical Safety Register and the Electric Safe Register, apparently.

    High earth impedance

    He is a NAPIT registered electrician so hopefully knows what he's doing... This is what he put in the report: When I asked him what further action he recommended, he said: Other than marking it as C2 ("Urgent remedial action required") on the report, he hasn't otherwise suggested that...

    High earth impedance

    Yes :-) Didn't mention that simply to keep my question clear and to the point. The electrician stated on his report that it's a TN-S supply and I understand that this is most common, so I have no reason to doubt his assessment. Given the advice above I'll get the vendors to get this...

    High earth impedance

    I'm trying to understand an issue my electrician has flagged up but have been finding conflicting information online. I would ask my electrician but he's flagged anything that doesn't meet current regs as "potentially dangerous" (which is nonsense when it would have met the regs in force at the...

    Domestic CU - how much more for RCBO vs. split RCD?

    Picking a random online retailer, they have a 10-way Hager split RCD unit fully populated with your choice of MCBs for £55 (VAT-in). A Hagar 8-way fully populated with RCBOs is £213 VAT-in delivered. So clearly he's having a laugh (esp as he's not VAT registered)... I would assume he's got...

    Domestic CU - how much more for RCBO vs. split RCD?

    Just the same number of ways; he didn't specify the makes (I wanted to specify Hagar but thought it better to go with whatever he's used to installing).

    Domestic CU - how much more for RCBO vs. split RCD?

    I'm currently buying a house and looking to get the old distribution board replaced with a modern consumer unit (it's perfectly fine, but there's an electric shower I want to replace which isn't RCD protected - I figure it's better to upgrade the CU to add RCD protection to all circuits rather...

    Part P - what counts as an alteration?

    I have an old electric shower which I'm looking to get replaced with a mixer shower. Unfortunately I want a shiny "digital" mixer shower which will also require a mains supply. Looking through Part P I can see that alterations are notifiable, but I can't find a clear definition of what counts...

    Building survey issues - rendering and damp

    Ah, that makes sense, thank you. The report made no connection between the rendering issue and the damp.

    Building survey issues - rendering and damp

    First time poster but please don't let that put you off :D I've just had a building survey report back for a house that I'm buying. It's a small 1820s end-of-terrace and surprisingly few issues were noted. I'd just like a little advice on what appear to be the most pressing ones. Can...
