@Taylortwocities so is the rule that if the junction box or accessory is fixed, then strain relief not required? That makes sense.

Hello All I thought that all junctions required strain relief so tend to use Ashley JBs or chocboxes. Is that right? If so, how are back boxes and ceiling roses ok? I guess for back boxes it might be good practice to clip near entry but that's not always possible for plasterboard boxes. I'm...

@Exedon thanks, I thought 10mm was ok but not 15mm. New builds lol. Yes I have ally tape and I know it can't be stuck directly to the pipes.

Anyone?

Hi, any hints & tips on fitting 15mm radiator pipes into thermalite for an extension? I wanted 15mm as the pipes are at the end of a long run so I don't think will balance in 10mm. Walls to be dot & dab over block. Both radiators are to be under windows so my planned route is to go down in the...

How about these, I had omitted some detail for clarity. As above I don't yet know if the live/loop runs directly between the two ceiling roses of if there is another light in the way. I don't have a continuity tester so I think that will require live testing - disconnecting all the wiring at...

Yes. Red 1 core and earth to first switch, red & black twin and earth between switches, and either red or black 1 core and earth from final switch back to the switched live terminal in the rose. Example picture showing 1 core black and earth.

I can do whatever I need to do, I'm asking for advice on the easiest! By loop I mean the perm live radial that goes between each fitting on the circuit. It's often labelled loop on JBs and ceiling roses. I also thought it's interesting that this isn't the usual way of wiring two way lighting...

Hi, I have two separate lighting sub-circuits on the same lighting circuit (i.e. same MCB in CU). I would like to do the following: 1. Remove switch 3 (sw3a and sw3b are separate switches on the same 1g face plate). 2. Can remove switch 1 if necessary or keep if easier. 3. Add another new switch...

A separate building under 50m3 doesn't need permission for demolition but a building over 50m3 does. Therefore I think this is potentially a grey area in that if the garage is attached does it need permission as part of the main house.

You can get restrictors for external doors to stop them slamming open. Home Secure™ uPVC Door Restrictor Stay. 335mm For uPVC, Aluminium, French, Patio Doors https://amzn.eu/d/g7ncl2Y Although for French doors there is something to be said for allowing them to open 180 degrees and use a catch...

@George_engineer are you saying that even the structural fibres... aren't? I thought poly microfibres were for crack control and the wiggly steel structural macrofibres replaced rebar?

It is tempting. Do the swap, pay someone £100 to "service" which would include flue gas check and adjustment if necessary, and keep the £1500 in the bank for any repairs. For a £500 installation it suddenly becomes worth it, not having to take a day of work and getting the warranty.

Yes according to the Worcester datasheet the pipework is identical so might not even be any soldering. Unscrew old, mount new, swap flue, check gases and fill out the benchmark book. Probably a morning's work I would have thought if nothing goes wrong.

Thanks @kidgreen61 I guess what surprises me is that it seems to be possible to get a much higher day rate for boiler swaps than for any other work. I can't imagine you would get £1k for a day of CP15s, services and breakdowns. And I would have thought that a straightforward boiler swap would...
