Interesting... the scheduled outage is from 08:30 to 16:00. I rang them to see if they'd tell me how long they expected the work to actually take- to my mild surprise they did.
Assuming no problems, they expected power to back on by 14:00, getting marginal if the cabinet is affected?
Coincidentally, while I was on the phone a leaflet arrived through the door postponing the work for about a fortnight. Can't help but wonder if the delay is to give OpenReach time to find some bigger batteries
eta: but it solves one problem- my UPS doesn't stand a chance
