Re-wiring a house where Glis Glis (rodents) are an issue

[Matt Hague]

Hey guys,

So there's a house that needs a re-wire after it burnt down. The most probable cause is glis glis chewing the cables. I've previously had to rewire a house with the same rodent issue and did it in FP as the metal sheathing would hopefully stop the rodents chewing through the cable. Does anyone have any experience with this issue and any suggestions other than FP cable?

Cheers.

I worked on a large estate in Buckinghamshire, where these pesky rodents were rampant. As well as causing a lot of damage, they make a rather annoying noise at night.

What about running your cabling in steel copex in floor and ceiling voids, its got to be faster/cheaper and more workable than steel tube or mineral/swa or the like?

Surely the owner is going to sort the problem? I mean even if you could run all cabling in steel conduits......if they that rampant they just going to Chew everything else anyways?

I think the problem might be temporarily halted due to the perpetrators being barbecued.

Rodents won't even notice the metal screen in FP, they'll be straight through that.

This kind of use of FP as a one size fits all cable winds me up. it's a fire performance cable, great for fire alarms and other things where fire performance is an essential requirement, but when fire performance eisnt required why use it?

I can't see steel kopex being cheaper than anything to be honest. It's hugely expensive.

Yep, might as well get the pyro tools out......

That is just what I was thinking.
I plan to do to this in Suffolk cottage due to past rat evidence and not wanting to cut large holes in a listed building.
MICC makes for a neat surface installation.

It certainly does, Billy. Good luck with the cottage... it doesn't all have to be surface though, as you probably know.

It is also partly due to a lengthy plan to reduce drafts as and when repairs are required.

I just need to find if it is worth borrowing the use of someones trade account to buy some MICC or trying to set up one with the wife's gardening business.
MICC is horribly expensive retail.

MICC is expensive wherever you get it from, I think the last time I bought some new it was over £600 for a drum of 2l1.5.
I usually buy old stock or part drums when people clear out their stores.

Mineral insulated would cost an arm and a leg, run all the final circuits using SWA cable.

Non insulated cables, nothing to chew and an instant death.

SWA isn't rodent proof.

They just chew all the outer sheath off, then once enough is removed the armor ends up splaying out and they just go through the strands and continue.

Got a photo somewhere an it's pretty impressive.

Granted, it'll last significantly longer than t&e.

MICC or steel conduit would be my preferred method here.

I know this property doesn't have a thatched roof, but is there still stipulation to only use MICC or steel contained wiring in the 18th?

I don't think that was ever in the regulations, I think it's just a requirement of insurance companies
