To give you some help this was my experience, I recently repaired mine after taking it for a regas at Kwikfit only to find it stopped working after 2 weeks they told me if I get it repaired they would regas it again for free.
I got a local fella to do leak test for free and it was found to be leaking from long pipe on the P clip, condensor and from the seals on the long pipe after the schrader valve 3 and 9.
He wanted over £300 to replace the condenser and £120 to replace all the pipes in the engine bay with rubber and reroute them around the battery tray, I declined.
There are various companys on the net that will do weld repairs on these pipes for around £25 a weld. A local company to me wanted £140 to replace the sections with ally pipe and regas and test.
Instead I took the two bottom pipes to Pirtek (the long and the short one 3 and 4) and had the sections with the p clips replaced with rubber for £77. Peugeot wanted £190 for both bottom pipes and trade discount would only be 5 to 10 % on these items, Part numbers: Long 6460-40 short 6457-WT. It should be noted that the connections at the end of these pipes are unique so there is no off the shelf non-oem pipes to be found.
I bought a new condensor from GSF for £53 using code "offer10" it turned out to be Valeo item. http://www.gsfcarparts.com/260pc0130
While you are at it you will also need to replace the receiver drier this is the one I bought and it fitted well. http://www.ebay.co.uk/itm/390590662773?s...1439.l2649
I replaced all the seals of the bits that I removed this kit seemed to cover all that I needed. http://www.ebay.co.uk/itm/310354569645?s...1439.l2649
A spring clip tool is required to remove the pipes the long one and another from the condensor 2 and 3. I made my own from some 25mm and 20mm copper pipe I had which used to push back the garter spring to remove the pipe.
Total cost was around £210 to fix including the original cost off the Kwikfit regas.
You could just repair the double pipe but you might find that it will only be a matter of time before either or both the two bottom pipes and the condenser will also start to leak as well.
