Conclusion
Certainly do not take the ‘do nothing’ approach.
I personally use, and have done for many years, UPS from APC. These have proven to me to be exceptionally good and reliable. Currently I have a number of the APC Back-UPS ES 700VA 230V which have been protecting my systems. They are also a nice small unit that can easily sit under a desk or somewhere discrete - but note: do not box them in as they need general air flow (don’t we all in the hot weather !)
