Soldering Yorkshire fittings

it is LF solder.

But the flux isn't suitable either

I think that depends on the type of flux. Looking at WRAS, it doesnt state fluxes not to be used, that I can see.

EDIT:
As stated I am not in the trade, and I am not advocating the above, just that it works for me.
EDIT2:
Although I cannot find ant WRAS statement that rosin core fluxes cannot be used, I have found a statement that it is not recommended in Potable water supplies... best not to then

I Always clean both pipe and fittings thoroughly with wire wool, don’t use flux, but always use fluxed solder wire. Heat the solder fitting to start, then heat pipe until solder ring starts to appear at joint. Use solder wire to then give a good fillet around joint and to ensure solder flows properly. Very rarely get any problems.

That can't be a correct method to solder.
With no flux until the last minute, the pipe and fitting could tarnish.
I see no advantage to avoiding using flux.
I use flux and never have problems.

Never heard of this technique. Where did you you learn that? I wouldn't even give that a thought, definitely the wrong technique. Do you actually know why we use flux ? Have you ever heard about capillary action ?
Without flux the solder will most likely just stick on the pipe but won't go inside between the pipe and joint. It's not a seal , will definitely leak.

Alright, whatever you do it's your problem. One day, it will be very painful for you - trust me there. Hopefully you do not teach someone such a technique.

If you heard about the capillary action then why do you do it in the totally wrong way? You are not starting to build a house from the roof top do you?

And yes without flux the solder can't run around the pipe there is nothing to suck in the solder that's why capillary action

i didnt say I didnt use flux. but I bow to your eminent collective wisdom

You clearly stated, don't use flux !!! Blow as long as you would like definitely would start thinking of changing your technique
