The four UK cellular operators are busy building up their 5G networks, but as far as I can see none of them are yet operating in the 3.5 GHz band around e.g. LHR or LGW. This could of course change at any time as they compete to gain value from their licence investments.
OFCOM have also been consulting on possible new uses within the 3800 - 4200 MHz band which is primarily used for satellite services. This of course is immediately adjacent to the air radar band.
I'm not sure I would say busy. The four UK networks have been struggling to roll out 5G - UK wants to be a market leader, but government meddling has broken the UK market. It is impossible to say whether the lack of 5G midband is due to airports, because they have not got there yet, or simply in the too hard to tick box. Some of the in-airport coverage is also delivered in a very bespoke way, which I suspect will take time to sort out.
