Advice on changing height OCAS
When recieving a Basic service outside controlled airspace from an ATC unit what is the protocol for changing height, do I request a climb or just inform ATC that I am climbing.

Under a basic service. No requirement to say anything unless you have entered into a co-ordinated agreement with the ATCO, possibly due other traffic.
Under a Deconfliction, Traffic or Procedural Service you 'should' advise ATC before any change in level. There are very good obvious reasons for this.

You don't have to but ......
You don't have to do either, in that context. Just bimble about in silence.
If the RT is busy, it would depend on why the RT is busy. If there's a lot of busy sky around I would not start wandering around unpredictably.

The majority of my customers ( Scottish Info on a Basic Service ) apart from advising the level on initial contact never say again if they go up or down.......thats fine by me and keeps the R/T to a min. That said there is always the one that will tell you every time he adjusts even by 50ft!! . Based on that if I give traffic information I tend to ignore the level and just use the geographical location in deciding if I should advise other traffic.....i.e. I may say "a C152 just reported Stirling last reported VFR at 2000ft.

ditto - when getting the usual excellent service from Scottish, if there's someone in the area and I've changed level, I'll drop a little update with my current level - but only if it's someone nearby or they're being told about me.
