Always advised not to put them above showers etc when I have had designs done.

Not above the shower, how about the middle of the ceiling?

I use plastic Hozelock connectors, outside all year round.

600 centres is standard so no worries with that. Insulation, vcl & service void before services.

Black pipe will be imperial, you will need an imperial to mdpe coupler.

I already have the PIR so will use it. Any advantage fitting rockwool in the service void on top of the PIR & VCL?

Thanks for the info, I am curious as to how I should be fitting the PIR under the rafters though. Is there any specific way the sheets should be cut/positioned to line up with rafters etc. It is 15mm plasterboard.

The photo has 170mm PIR in between the rafters, rafters not visible for the tape.

I am at the stage of fitting insulation under the rafters, vcl, 45mm service battens & plasterboard. Is there any particular way the insulation under the rafters should be fitted? Is it better to stagger or is it irrelevant due to service battens? Do the ends of the sheets need to be joined on a rafter or are they ok just on the insulation between the rafters? What is the best spacing for the service battens? 600mm seems quite a bit. The height from the top of the wall to where the ceiling will be is 1280mm. Any photos of previous work or suggestions would be appreciated.

It’s really not difficult to do, sounds like you have all the routes sorted. Give it a go & save the money for something else, plenty of help available on here.

Maybe attach some photos, someone may be able to help.

Can you put up a photo of the sockets once fitted please.

@Pocster’s favourite 😳

Big one yes but there are two smaller ones…

Looking good 😎 What are the small rectangular cut outs for?
