What's the application? 12kV arrestors are only a couple hundred bucks each. Not sure about the install side.

You won''t be permitted to install it at the meter like some of the ones you rent from the utility are installed. You can install on at your service equipment. The utility has no say about installing one at the service equipment.

How much is rent?

How well do they provide maintenance, as in how often do they check to see they are still ok?

I'd probably opt out for my own unit if they are going to "rent" it to me, unless maybe rent was 50 cents or less per month, then I may consider it. 50 cents a month is 6 dollars a year, 60 dollars in ten years, 120 dollars in 20 years. If you needed to replace one within that time you are probably either ahead or near break even point on your investment. If you are paying labor to install/replace it you are much more likely to be ahead after 20 years of rent at the rates I mentioned.

What is a "surge protector", and what do you want it to do?

Does your utility provided unit include insurance? If so what does it cover? What are the technical specifications on any unit you might select, commercial or power company?

How do power company specs compare with commercial units?

What do you want to protect against?

Are whole house units better than point of use, or are both needed?

And I could create more questions.

You need to understand how a typical surge protector works. Many surge protector simply use one or more MOVs. These work in conjunction with the source impedance feeding the MOV.

Think about how source impedance in combination with an MOV voltage-current curve provides some protection and how good that protection is.

Some MOV curves are at:

Note that the plots are on log-log scales.
