IPM retained some of the Mercury phone boxes but all the blue hooded kiosks were all replaced.
The GPT Marconi telephones were also swapped for IPM's own payphones.
As of today, the same telephones are in use today by the present owner. Marconi still produces and maintains BT and Spectrum Interactive payphones.
