Seeking comments on email for the replacement of systems

I would like to seek someone’s comments on the sentence structure of the following email written to users for the replacement of the UPS systems. Thanks

Dear Jackson

Regarding the preventive maintenance (PM) service of UPS 1 & 2 at ABC’s building, on 20/F, XXX’s company is the service provider for UPS. They confirmed to us that the UPS was End-Of-Service Life and also no spare parts are available in the UK market. Therefore, XXX replied to us they cannot provide PM services to both UPS at TWP’s building referring to the following email.

For the current situation, the UPS may be breakdown during the battery replacement and is beyond repair. As such, it is not recommended the replacement of the battery and battery rental service for the UPS at ABC’s Building. Please consider replacing new UPS systems to avoid any service interruption.

Regards
