I'm not sure if the culms are dead or merely defoliated. If the culms are dead, the plant might resprout from the roots next year. When the weather is Septemberish, tip one out of the pot and have a good look at the roots.

Many thanks for your super quick reply!
Some interesting thoughts. The wind could be an issue. We have an Acer on the terrace by our front door and in previous years (like the bamboo) it has thrived. Except this year it is in a sorry state, wind burn seems to be the diagnosis, a possibles cause for the bamboo's ill health.
We have had a fair few vine weevils on the terrace but haven't noticed any on the balcony. Bu then don't spend much time out there as the bamboo looks so sorry! Will wait until the weather is 'Septemberish' to investigate that avenue.
I guess we should prune down the nearly dead/dead culms in the winter to encourage any new growth?
Any further thoughts on that and previous problem much appreciated.
