Yes

Thanks James - how can I set it up? As the internet provider is different it does not seem to work, 

The app itself holds very little data.  The account and system info resides on the Sonos hardware, so the answer is yes.

Thanks. Any idea of the method ?

Is it as simple as using the “add speaker or component” option? When I tried this in Portugal the app did not find my speakers as they were not on the same internet system as the uk? Thanks 

Once you get on the WiFi at the new location, start the app and when it doesn’t find a system, choose “Connect to an existing system” and follow the prompts from there. 

Thanks. Will try. 

Didn’t work as the ISP is not the same as Uk

ISP is irrelevant.

Are the devices brand new or factory reset? If not then reset them if you brought them from the UK and had already been set up.

You need to create a new system in the new location (you can use the same email as your UK system). Now, the new app is unreliable at doing this, but once it does you’ll be fine.

Thanks. All new kit. Will try. 

Thanks all, got this sorted at last. Appreciate all your help. Cheers.
