Just to add a little here as well. UKA is steeped and heavily biased towards Track and Field. T&F has structure in terms of coaching (which we have) and officials (which we haven't).
Not only do they expect officials to go through qualifications, they expect them to continue to renew to validate their qualification.
This year for example has seen a big problem with the long throws at T&F fixtures because the appropriate grade 2 officials to run the long throws events were in short supply and their H&S Modules were in the main out of date (EA had not set up any courses)
So there was a huge problem in the sport nationwide with clubs trying to get their appropriate officials on to a H&S course.
How does that relate to us on the Fells?
Well I'm not sure they see us as athletics tracks in the Sky but it's a nice image

We do have people like Sara Rowell linked in to UKA at a high level so I'm sure we have quite a reasonable voice there.
BUT
with the connection now, I am sure that there will be a growing pressure to follow the mainstream way of having a proper officials structure for the fells such as we have for Cross Country and Road.
In fact I would go farther - I think there would be a need for the FRA to instigate some kind of officials and/or ROs structure regardless of any tie up with UKA.
It's the way the world is going.
