    Ducting for a cooker hood

    I didn't anticipate this being so expensive. In the kitchen we are renovating we need to take the air - up about 1.5 m vertically - back from the wall to get around a steel beam sitting between the first two joists wehre the fireplace was removed - then up into the attic and across about...

    Installation of humidistat fan

    I'd struggle to recommend Humidstat fans based on my experience. Cheap one (bent metal strip approach) is OK but the much more expensive Expelair one has been a nightmare - it will switch on with ambient humidity on it's lowest setting (ie with the window open!). Expelair's response was just...

    Low Voltage Lights

    Fitting contains 24 x 1W high powered white LEDs with light output comparable to 2 x 26W PL ---- Doesn't fill me with confidence - those are really old, poor, LEDs - the "stick a lot of individual LEDs in" is the way things are going. A small number of good ones and some reflector is what...

    Life span of wiring?

    All good advice from BAS though I suspect practicality could limit you to accepting some of those rather than all. A "less than flood wire" install of Cat6 or Cat6a cable is well worth thinking about if full is too expensive/difficult. Think about linking the key places you would want IP...

    Low Voltage Lights

    I'm thinking about this now. We've got 14x LV 35w (some might be 50's) halogen spots on 2 circuits in our kitchen ceiling and they're the lights in the house that spend the most time switched on. 6 hours a day? 10p a KW/h? - I reckon they probably cost about £100 a year to run. Add to that...

    Wireless room thermostat: wiring for the receiver.

    Now this, on the other hand.... http://www.nest.com/why-we-made-it/index.html What the man who invented the iPod is doing now.

    Wireless room thermostat: wiring for the receiver.

    No, and wouldn't want to, but have a certain admiration for any piece of equipment that looks better as it ages and is damaged in use. A battered Defender looks good in the way an old pair of jeans does while a threadbare suit or battered Ford Mondeo will always just look crap. No problems...

    Wireless room thermostat: wiring for the receiver.

    Hmm. I reckon mine must be the Digistat 3RF (with the 7 day timer). Decided against the + model which is the one that's supposed to have the 'intelligent start' as at the time our heating system was struggling to keep the house at the temperature we wanted it at. As an aside ultimately may...

    Supply in converted house

    Effectively it's inside the flat (upstairs flat and it's running along the edge of the living room wall). Hard to see how anything done in the house could ever damage it.

    Which, indeed, I did. Wylex as well.

    17th Edition CU's

    thanks - i was just wondering if there were any changes 'under the hood' that I couldn't see.

    Supply in converted house

    Current cable is a big fat white insulated multi-core cable. I've not had anything open to judge the cable size but it's probably from a 20 year old installation where the electrics generally seem to have been done to a fairly high standard. I know that's not a lot of help. I'm fine to...

    17th Edition CU's

    ricicle - thanks ban-all-sheds - no thanks. I'm fully aware I could buy the regs and try to decipher them but the reason i've asked on an internet forum is because I'm hoping to get an answer. Of course I could just be a sucker looking for personal abuse in which case I've probably come...

    Supply in converted house

    Fair enough. I'd still like a view on it. If the answer was along the lines of "that's very unusual and over the top" for a job that's probably going to add a few £100 to the bill then I'll think about finding another sparks.

    Supply in converted house

    Again, just looking for views here. Converted Victorian house. 2 flats. Main supply comes in to two meters and switches in the shared hallway. From those (fused) switches the supply runs to CU's within the individual flats Electrician is suggesting that need to: - replace the...

    17th Edition CU's

    Can anyone clarify exactly what changed in CU's for 17th edition? There seem to be for sale CU's that are marked as '17th edition' and those from the same manufacturer that *seem* to have identical features but are not (older stock or something more?) What would be wrong with a modern...

    Bonding/Earthing

    Ok - so we're only talking water/heating/gas and they'll all be bonded in the cupboard at the meter. Cross bonding within the bathroom and kitchen is no problem but does that need to be run back to the CU as well? That's the difficult/expensive bit (in terms of cabling)

    Bonding/Earthing

    Doing a refurb at the moment. I'm doing the first fix electrics with an electrician doing the final fix and signing off. A new fuse box meeting 17th edition is going in so all circuits will be protected by RCDs. I working on the basis that - Main bonding - at the Consumer Unit the...

    Part P and building control

    I am fast coming to that conclusion. You live and you learn. So, back to the original question - Can anyone recommend a South London electrician? The handwritten note from BC just refers to "Electrical Cert" so I will seek clarification direct - I'd thought I might find out what this was...
