So been to look at a job today, several lights to put up around the outside of a house.
there is already 1 light in situ I plan to use to supply the other lights.
no access to fish cables in the house so everything is going to be surface mounted Outside..
money is tight so conduit not an option.
i was thinking white flex clipped under soffit or twin and earth clipped in mortar join...

does anyone have a preferred method ?

FP cable P clipped is also another option possibly depending on money

Conduit would be cheaper in the long run than what you are proposing DD in my opinion.

Run the options past the client. Will probably be dependent on what they think looks best.

they are happy with anything clipped direct.
i mentioned pvc conduit but they don’t want to pay for extra materials for the job.

is FP cable considered suitable for exterior clipped direct ?

Don't think FP cable is recognised by BS7671 as a general wiring cable, could be wrong best check yourself.

It also looks like it was done by DIY Dave.
there is already a load of sky cable , phone cable and old tv cable clipped around the house so what ever I do won’t look too bad :)

You cannot run flat T/E where it will be exposed to sunlight.My preferred method is Hi-tuf.
the last time I did a job in hi tuff I remember it being a right nightmare to strip the outer sheath...

Strikes me as though the client is running this project, and won't listen to your advicel, then do yourself a favour and tell the client to get someone else.

I would think the labour costings of chasing cable into the mortar joints and then repointing, would cost a whole lot more than using black PVC conduit.

no chasing the mortar ,everything will be surface and clipped direct.
i mentioned using black pvc conduit but they don’t want to shell out for the extra materials.
its an old boy we know, so I’m happy to do a basic Job as money is tight...

that’s good to know , I remember I bought a drum of the stuff a few years ago and it was an absolute pig to strip
Not a fair price comparison, if you are doing a Mate a favour is it? will you be testing and issuing a certificate for the work.

I always test my work, and issue A hand written mwc

i have a pad of old dual leaf mwc in my tester box
 
If you are not going to install a wiring system suitable for the environment then I see no point issuing a Certificate, it won't be worth the paper it is written on unless I am misreading this. The fact they cannot afford to have it correctly installed is irrelevant.
 
As an aside, is the existing circuit RCD protected?

I want to do The best job on a tight budget...
Looks like Hi tuff is my best option , relatively inexpensive and I can get cut the exact amount I need so no waste

i Can’t remember off the top of my head , I did some work at the house years ago and iirc was a 16th Ed split board, so lights would be on the non Rcd side.
might have to move the mcb over to the rcd side or fit an rcbo.

Flexishield is another option that is outdoor rated and fairly good at staying put once formed and clipped. You get it in white and black, so might be easier to get it to match.

Down side is I think you only get it on 100m reels, but handy stuff for other jobs as nail-safe if used on non-RCD circuts that might be < 50mm from wall surfaces, etc.

thanks will look into this

thats why I was looking at possibly using FP as it shouldn’t sag like flex

It is similar but possibly a bit cheaper.

They also do cat-urine-flavoured versions of it if you are in an area with rats...

Decent stuff for the job. Just one point, I used some last year for outside lights, clipping every 15 inch or so. Fixed with p clips. It's in the sun a lot and seems to have sagged quite a bit between fixings. I'm calling in a few weeks, needs looking at before the nights close in.

FP is OK for mains installation but NOT outside. In the sun it falls apart over time. I remember some on a factory roof for security lighting. It really was cream crackered, all over the place.

It depends who is doing the considering!

Does the circuit need a fire performance cable? If not then why would you use FP?

A bs8346 cable such as flexshield is of similar size, shape and construction but far better suited to general purpose wiring, and cheaper, than a specialised fire performance cable.

Cables or PVC conduits installed externally should generally be black and not white.

I like my pyros orange.
Yeah good ole cable, just had a look very expensive, over £5 a meter for 2L1.5.
