There have been no major changes to the Phoenix network in regards to talk groups since late 2015.
Here's a Retevis RT8 code plug - got the radio yesterday from someone in the Midlands area.
It does not have TG's 83, 84 & 85 but you can add them and modify the code plug to suit.

Local repeaters GB7CT , GB7WL , GB7HR , GB7NS , GB7GF and GB7BK
