FAQs

Common questions

How quickly can you respond if we lose power or have a UPS fault?

Response times depend on your support agreement and location, but we prioritise critical incidents and can provide rapid triage, remote guidance, and on-site attendance where needed.

Do you only support systems you originally installed?

No. We regularly support existing UPS and backup power systems, including legacy installations and multi-brand estates, whether or not we completed the original install.

Can you help us choose the right UPS size before purchase?

Yes. We can review your load profile, runtime targets, growth plans, and site constraints to recommend suitable UPS options with the right capacity and resilience.

Do you offer planned maintenance contracts?

Yes. We provide planned maintenance options that include routine inspections, health checks, reporting, and proactive recommendations to reduce unplanned downtime.

Can you supply and replace UPS batteries?

Yes. We offer battery testing, replacement, and post-install validation to help maintain runtime performance and avoid battery-related failure risks.

Where do you provide service coverage?

We support sites across the UK. If you share your location and requirements, we can confirm coverage and next steps quickly.
