Slightly more embarassing than that - submitted notification, then through illness & lethargy took no action until this summer. I am now rapidly approaching the three year limit of 30th November but am not quite ready to get the LBO out to inspect. Will do just that tomorrow. Just...

Thanks

The conduit is in brick wall (or blockwork). Ah. got it now yes, you are right. on going back to have another look at table 4A2, it looks like number 59 applies - Non-sheathed cables or single-core cables in conduit in masonry having a thermal resistivity not greater than 2 K.m/W o ...

Just wanted to check my understanding. Am I right that running single phase cabling (single core, sheathed) in conduit embedded in a wall (recessed ~ 40mm) falls under reference method A ? Which from table 4D1A would then make the maximum allowable current for 1.5mm sq. cable 14.5A ...

I'm installing thermal & acoustic insulation to the internal walls, floor & ceiling of my flat.

On the building notification acceptance letter I have from my local building control, the last paragraph states : If the work covered by this acceptance letter is not commenced within three years of the date of this letter, then the application will no longer be on deposit. What is...

I have previously posted about splitting the ring in my flat to install additional new sockets whilst insulating the walls in my flat. The thought has just occured to me that there there is one wall in the lounge, that if I insulate, I will need to extend the exsting wiring by say 100mm to...

Yes, you're right. I do mean method 102. Had the consumer unit replaced a while back so circuit should already be protected with and RCD but will check. I think once the plasterboard goes up the distance from to the cable will be > 50mm but thanks for pointing it out. I'll run it...

I understand from Part A that when chasing walls, the chase can be no deeper that 1/3 the wall (or leaf) for vertical chases and 1/6 the wall (or leaf) for horizontal chases, which for a 102mm brick equates to 34mm for vertical runs and 17mm for horizontal runs. There is also that catch all...

I am looking to split the ring in my flat to install some additional sockets whilst installing thermal & acoustic insulation. My intention is to run new 2.5mm T&E cabling directly clipped to the existing, plastered brick wall horizontally from the existing socket to the new location. The...

RonnyRaygun / Tony1851 thanks for your responses. Just to be clear with regards to including the perimeter of an adjoining building does that mean I can include the perimeter / area of both flats either side of me ? Or, can I even go so far as to include the whole ground floor of the 4...

I am looking to insulate my 1969 build ground floor flat. External / Party walls & ceilings I have a handle on what I'm doing. When it comes to the flooring, I am wondering how much leeway my local LBA might give me in new flooring thermal elements. I am looking at installing Spacetherm...

No there's no plasterboard at all. So far as I can tell, there are concrete beams running across each room between the load bearing walls - mainly because this is where the cracks are from settling. Where I removed a fitted wardrobe, I can see block work. This block work is nominally flush...

I am just about to embark on my long planned renovation of the thermal elements of my flat. I have the landlords approval, and today received acknowledgement of receipt of my building notice. So far, so good. I will be insulating the external walls, internal party walls to adjoining flats...

Its morning, daylight and I can post some pictures : Patio is approx 3m by 1m. I had a go yesterday with a good old lump hammer & chisel, managed to do this in ~ 2 hrs before thinking a power tool would be better. For all my inteligence I can be slow sometimes. :shock: Besides it...
