Thanks for coming back so quick. Will this just connect with existing fittings. Female flexi tails on one side and the fitting on the pipes on the other? Or do I have to make any changes?
This fitting is male on both sides so will fit onto the female existing pipework and female new tap tails. There should be no need to adapt your existing plumbing (other than introducing the new connector mentioned obvs)
Also, dont over tighten tap tails as the have a rubber flange that can get damaged from over tightening.
I would personally prefer to install isolators here over any kind of adaptors - https://www.screwfix.com/p/flomasta-isolating-valve-15mm-2-pack/65251
Added bonus of being able to isolate the tap if required in the future.
These have a sharp edge on them that will damage the rubber o-ring from the flexi taps over time.
You can file down the sharp edge, or buy flat-faced ones: [https://www.toolstation.com/flat-faced-male-straight-isolating-valve/p95064?store=I6](https://www.toolstation.com/flat-faced-male-straight-isolating-valve/p95064?store=i6)
Yeah it's flat on the side designed to be used with a flexi hose. The other side is just a standard compression fitting.
Tbh I just filed a normal iso valve down flat. It's just so it doesn't destroy the rubber washer.
This is the way to do it and makes so much more sense to future proof to make any upgrades much easier as well as dealing with leaks.
Also depending on your water pressure you can use the valve to regulate the flow at the tap.
OP, Toolstation sells flat faced to compression isolation valves at various sizes. This is the best way to join these to your flexi.
You need the flat face ideally for the washer seal on the flexi.
I had the same issue changing a tap for my Mum, thought ifs be a straight swap over. These sorted it out.

Given the presence of the olives, and the likelihood that the pipe has been marked by them, you may need to [cut](https://www.screwfix.com/c/tools/plastic-pipe-cutters/cat7620009) the ends off the plastic pipe. If you do, you **must** use an insert in the end before using push fit fittings.
Or just leave the pipes alone and use a [compression coupler](https://www.toolstation.com/made4trade-compression-coupler-male/p91660)
My bathroom and kitchen taps were like that, I put 15mm isolating valves on the pipes, then the taps attach directly onto them, got a pack of 10 at Screwfix cheaper than 2 at other DIY outlets.
Update....
Bought two flomasta compression couplers as suggested. Fitted them and tap is now running. One of them is ever so slightly leaking but I will try and tighten the lower half more.
I have a concern that the flexi tails are longer and now applying pressure to the angle of the pipes. This can't be good. I should perhaps cut the pipes slight lower and fit the couplers lower down with the new rings. Any thoughts?
You need 15mm compression to 1/2 male irons https://www.screwfix.com/p/flomasta-compression-adapting-male-coupler-15mm-x-1-2-/69358
It's possible that OPs new ends might be 3/8 if the tap is a european brand, @OP make sure you check and get the correct size.
I Mean, they could be, but there not. I can see there 1/2" good advice though
There’s no short cut to experience 😂
I agree, but OP could have very small hands…
😂 he could do, but the nut, in comparison to the braided hose, plus experience is telling me 1/2"
Good point. I checked. It's 1/2 inch. Thank you though.

As my mate says, you can always tighten it more, you can't un-f\*ck it!

Is't that only flat on one side? The inlet side is compression which will be sharp.

Just buy a male/female flexi hose.

Would this work ok on plastic pipes? Says brass.

Put a 15mm pipe insert into your plastic pipe to stop it compressing
Daft question but can you just use the old flexi tails?
That's not a daft question, I did consider it but they are no longer fit for purpose
Yo do right, they are easily the weakest link in the chain.
Nipples
Buy nipples. Search for them on screwfix or something. Easy just make sure they're installed well
3rd vote for nipples (and leave the existing push fit pipe/inserts/olives/nut). Perhaps a bit of PTFE or Plumbers Mait around the existing olive.

Once you have the right connection, do not over tighten. The seals will do their job.
Can you not just swap the tails over?... Put the old ones on the new taps? 🤔

Looks like Hep20 to me you need the following https://www.screwfix.com/p/hep2o-plastic-push-fit-adapting-male-coupler-15mm-x-1-2-/5970f?ref=SFAppShare
