Have implemented this via drone.io. Note that this currently doesn't account for changed dependencies and only runs the gulp production and gulp fractal:export tasks.

This was, in hindsight, closed too quickly.

We encountered issues with drone.io not compiling assets properly. We tried moving this to happen to the pre-deployment stage (allowing us to alleviate the npm memory issues we keep having on production) but drone.io was struggling to do things there.

I've additionally tried using DeployHQ however it encounters permissions errors when their script tries to compile assets serverside.

Will investigate whether it is possible to produce an internal deployment procedure or whether there is a third party service that can suit our needs.
