I did some digging into the network upgrades - with some areas on 750mhz networks and others on 860mhz I decided to look for figures on this.

At year end 2015 only 13% of homes were on 860mhz capable networks, in 2016 this rose to 25% and at 31/12/2017 this figure was 78%.

I suppose the next question is whether the new kit is 1Ghz capable (approx 65% of the network upgraded since 31/12/2015).
