Since you reside in the UK, your cables are different.
With coaxial cables, its about the same. There should be no major difference with running it near electrical and not. I have a run running with electrical and coax parallel for 100ft. No interference.
If you already experience interference, then go for a more shielded cable.
About the connection, can you provide a picture?
