Hi I am in Manchester too and I feel the need to correct some of the above.
It seems that yes, the majority of the Rabonim hold that the eruv is Kosher albeit after utilising some “kulos” which a frum/bnei Tora community may not be happy with.
Most seem to be saying that the Eruv can be used “bshaas hadechak”.
The inyan of Chinuch is only an issue by one or two but has not been the main focus. (as mentioned above most Manchester people know who the Rabonim referred to are and those who dont, dont need to IMHO.)
The drosho which I heard in Prestwich (north Manchester)also stressed the need not to denigrate those who are machshir and/or those who carry.
