To be honest, I'd remove the sycamore and replace it with a tree that is more attractive and creates a less dense shade. Sycamores do grow absolutely huge, the shade underneath is dense, they invariably get a sooty mildew on the leaves so they don't even look attractive and they're not particularly good for wildlife. And then of course there's the problem of the seeds all taking root around the garden ...
While they're perfectly good rural hedgerow trees in my experience they're not really suitable for a garden - I'd take it down while it's still manageable - it'll cost big money to do it when it's bigger, and that will be in just a few years' time.
Sorry, I'm a big fan of most trees in most gardens, but if that was mine Ithat's what I'd do.
