Just an update...
I decided to go with the uninsulated spade terminals (the type on the existing flex).
For some reason, I assumed that they were 4.8mm. I read the reviews for 4.8mm crimps on Amazon and decided to buy them from a company that specialises in selling electrical connectors. I found CableCraft. Min order for free delivery (next day) is £20 so I purchased 200*4.8, PVC crimp sleeves and 100*2.8.
I then spent hours looking for a ratchet crimper and found a German branded BGS 1419-Ratchet Crimping Tool (probably made in China) for only £14.
I used some off cuts of cable to get the technique right.
I then noticed that my 4.8mm crimps were too small so back to CableCraft for for 200*5.3 crimps, PVC covers and other stuff that I don't really need.
I crimped the new longer flex and put 1 solitary PVC sleeve on the live. The mother was happy and I was confident that the fittings are secure.
I suspect that the insulated crimp set that I previously purchased from Amazon may be rubbish and should be binned. The only crimping I had previously done was blue butt splices from a reputable supplier. As a novice, I like the fact that with the uninsulated crimps, you can do a visual inspection of the crimp before doing the tug test.
Thank for all of the advice offered.
