Loop in method for Lighting Circuits

Please see the lengthy recent discussion here.

Would only ever consider taking the feeds to the light on a difficult re-wire where it is just easier to get 1 cable back to each switch position.

For new work generally always feed the switch or on a rare occasion feed a JB up in the loft space...

Thanks - its still a wooly subject then I see. I like Andy's point about more wires to connect at height means less safe than at the switch.

Loop in method for me is a lazier option. It's easier and cheaper for the "I will only buy twin n earth" brigade I know that but in the current climate an open invite for introducing more risks. Stick to higher standards. Germany and France condone it. Do we go all out Brexit on it ?

Loop in at switches only - yes please

Most of the properties that I work in use the loop in lighting method at ceiling roses with T&E cables. Occasionally I find single insulated and sheathed lighting cables. Mr. D.I.Y.er can still get a shock at the switch if replacing a switch if the supply is run there first. The loop in system can be of use for ceiling light fans. The permanent line is connected to the fan via a small cord switch on the fan light, and the light is controlled independently from a wall switch. There must be millions of homes wired three plate at ceiling roses, proving its popularity.

I do think statistically Mr DIY is more likely to change a pendant than a plate switch - good comments though made by all - many thanks

Dunno about that, see plenty of diy switch swaps usually chrome finish jobs, had one last week where a chap had replaced a two way withs metal front and connected the yellow to the earth terminal, his job is a H&S consultant

Generally on new work I loop the live and neutral through the switch boxes.


But I’m not obsessive about it, if it is more practical to loop through the light fittings I will do so.


Do not start worrying about if a DIYer understands how the lighting is wired, if they don’t they should leave it alone. I have seen an incorrectly wired  plug that had full colour illustrated instructions on a label attached to the flex telling you how to wire the plug within 200 mm of it.


You cannot dumb down electrical installation work to make it possible for idiots to work on it at some future time.
