I all , i've had same problem but in a semi detached every time my neighbour used his taps or washing machine i got water hammer anyhow i did all the normal things like turning my stop tap down & making sure there wasn't a air lock. Then i bought 3 water hammer arrestors which fitted under the bath ,back of washer & one before the boiler (cold water pipes) IT DIDN'T DO ANYTHING.
After a couple of days later i noticed that when my neighbour started running his taps i could feel the water in my cold water pipe just after the top tap ,like it was running .So i bought a 15mm one way non return valve & fitted it just after the stop tap Magic problem solved
