They will probably be going to use a fairly beefy generator which will be

If they are to be using the generator to power several properties it will
pretty big, to allow for the typical loads of cookers and showers that the
users may power.

Yep, the bigger generators have much more "spinning reserve" due to the
mass of them. They also use hefty copper wire in the windings which
helps voltage regulation. A totally different ball game to the cheap
domestic generators that are really only OK for steady loads
considerably below their quoted output, or for appliances that do not
really care about the quality of the mains.

Therefore the quality of the supply will probably be fine for your
computers, especially if they are fed through UPSs which can protect against
under and overvoltage conditions.

Good advice.

I would hang a multimeter on the mains and monitor voltage excursions
while the work was being done... just in case.
