Replacing basin tap but flexible pipe to replace

[Luca]

Hello,

I'm replacing my hot water tap, but only now I realized that the hose nut is bigger than the tap connector
I'd like to remove the old flexible but I do not know what I have to loosen
Can I keep the old flexible pipe(I know it looks orrible)and buy an extension+adaptor??
The new tap is a Bristan like this

But basin taps are normally 1/2 so a standard 1/2 flexi should do

NO. Those hoses WILL shortly fail. They are at the end of their useful life.

For longevity and reliability install fixed copper tails.

I agree but the problem is what I have to loosen?

The compression nut after the valve on the flexi

Which one?
1, 2 or 3?

2 and 3 undo the nut no 2 and 3 should pull off with the flex

I tried to do it using two wrench but 2 and 3 are so stiff! They seem stuck..
