You need a back up generator, with fuel in place.

Other than that maybe a call divert to mobiles and pen and paper.

But with the like of Uber, it's not just power that's required, but for the Yanks to never turn off their satellites.

Two machines with screens and a router will take about a kilowatt and a small generator for this wouldn't cost much more than £100.

id allowed £250

BTW, would you know if a computer run off an inverter would need a sine wave (flat 12v) output, i assume an unsmoothed half wave wouldnt work

No you just get a small petrol generator and that generates 240 volts just like the mains supply.
Connect your equipment via a long surge protected extension lead and Bob's your uncle.
We had to run our offices this way a couple of years back.
But only because the kebab shop was closed that day. :lol:

You can get UPS's as well (uninterrupted power supply), basically just backup batteries. Commonly used in IT situations where a power outage would mean data loss.
Advantages are they are on constant charge so always ready and if the power goes off they kick in automatically and instantly.
How long they last depends on the size and type - anything from a couple of hours to days.

I've seen an office with 300+ cars (only about 100 working at the time though) revert to voice on the Auriga system when their office fuse board blew. They wired the radio up to a car sat on the office ! Most of the new ( non English ) drivers went home, didn't have a clue about radio procedure.

Inverters or UPS units are good but without mains power they're only going to work for as long as the batteries last.
We use these at all our sites to keep the power going for just the main dispatch PC and any other critical bits like routers.
They give about half an hour at best but that's generally long enough to get any important stuff out and to get the generator started.
Some ask for bigger UPS units rather than looking at backup generators but where do you draw the line with power cuts?
We had companies in Lancaster and Morecambe with no power for nearly four days recently and a battery backup for that would need to be the size of a substation.
And to just to make matters worse, a lot of the mobile masts ended up failing as their backups failed.:shock:

The thing is, given that small generators can be picked up so cheaply these days, it doesn't make much sense not to have one.
Maybe this will serve as a bit of a wake up call for companies to give some thought to their plan B.

Bill :)

Under their licence would they be able to keep fuel in the office, or even run a genny out the back due to the noise for neighbour's

I doubt that there would be any mention of such things on an operators licence. modern generators are not as noisy as the older ones and they would normally be outside the building but inside an acoustic enclosure if necessary.

fed off a car battery with the car running it would never flatten the battery tho

we are talking what to do in an emergency, so long as the landlines arent down it could work, even then, with some diverts (and a dongle for tinterwebnet) you could theory - maintain a service

I don't think the dongle would be fast enough.
