Useful to know
Before we attend.
Can you work on behalf of a UPS agent or dealer?
Yes. UPSSOS offers on-site support on a contractor basis. Scope, customer contact, reporting and commercial terms are agreed for each assignment.
Do you offer emergency attendance?
Emergency call-out enquiries are welcome. Availability and an attendance time must be confirmed before a visit is booked. No fixed response time is promised by this website.
What information is useful for a repair enquiry?
Please provide the site postcode, manufacturer, model, UPS rating, displayed alarms or fault symptoms, and access requirements. Photographs and service history can help once contact is established.
Do you provide battery replacement and installation support?
Yes. UPSSOS offers VRLA battery replacements, impedance testing, battery string installations and UPS or battery upgrade work on a contractor basis. Share your equipment details so compatibility, scope and site arrangements can be confirmed.
Does impedance testing confirm battery runtime?
Impedance readings help assess battery condition and identify changes or unusual readings. They do not directly measure available backup runtime or replace a capacity test. Findings can guide further investigation and maintenance planning.
Can every UPS fault be repaired on the first visit?
A repair depends on the fault, system condition, parts availability and agreed scope. The visit may begin with diagnosis and recommendations before further repair work is arranged.
