Rewiring a flat

[Welshsparky36]

Hello I'm Dave, im new here so please be gentle with me. I am looking to do my first job for my cps scheme, rewire flat with plasterboard walls and ceilings. I would like advise on the best way to chase cable routes to minimize repair work, but also allows for cables to be sufficiently fixed throughout the entire length, any pics examples would be fab from you pros thanks a million

is the plasterboard all dot and dab, or on studded walls?

I believe studded many thanks

usually you can fish cables up and down, bearing in mind that x members in the studding walls are usually at about 1200mm. if fitted.

With the 18th including that cables above ceiling should be fixed with fp fixings etc, plus I dont want the risk of the cables floating about in case they were to be inadvertently pulled upon when changing a lamp for example

Fishing would be obviously much easier, however I wanted to avoid cables being unfixed or floating in cavitys, or am I being overzealous??

cables dangling down inside studded walls complies with most new build practices. advantage is if sombody drills into wall, cable/s will move away. no bangs.

From an engineering perspective i agree, many thanks. If I may add the customer has a 60amp plastic wylex isolator at the incomer, the tails are 16mm to my knowledge. The cu is over 3 meters away. The customer is trying to achieve a very minimal look ie kitchen sockets in the kitchen units, operated by gang modules. The customer really has a budget for reconfiguring not rewiring, but due to the fact the wiring is red and black and he wants every socket and switch moves I believe a rewire is better to eliminate jointing of the cables

I am level 3, 18th, 2391 52 just for to confirm. Forgive my questions but due to taking on my own work I really want to ensure I do it to the best of my capabilities. Thanks for your speedy non judgemental expertise

Would you agree?

Always better to re-wire rather than introduce a joint that can fail far easier in the future due to expansion and contraction loosening off the connection.

It's a valid concern, although if cables are behind plasterboard, then generally the concern of premature collapse is less of an issue imo. Vertical runs less so still where they are unlikely to be an entanglement risk.

The more important issue is to have secure fixings at each termination point, fixed suitably to avoid vibration etc. (even with Wagos)...

I assume you mean changing a light fitting rather than a lamp, at each light fitting the cables should be restrained/fixed in some way so this should not cause or become a problem, hope you have a decent set of electricians rods, some more flexible than others to help feed any new cables through.

Like most of you guys probably encounter I have a client with a 25 year old install, that wants so many items moving and reconfiguring (2 bed flat) that to do a eicr and re jig everything plus knowing the odd joint will be concealed I'm not happy with that personally
