A wealth of experience

At Carter Sullivan, we’ve specialised in UPS installation for over 20 years, handling everything from the initial site survey to full project management and commissioning. As official partners of several major UPS manufacturers, we install systems that are tailored, compliant, and built to last.

Our engineers work to the highest industry standards, and we back it all up with our support and maintenance. When it comes to protecting your critical power, you can trust our experience and partnerships to deliver.

Why install with Carter Sullivan?

Over 20 years of experience
We’ve been setting the standard for the installation and maintenance of UPS systems for over two decades. Whatever your critical-power needs, you’re in safe hands with us.
No cookie-cutter solutions
We devise a bespoke approach for every client. We don’t do cookie-cutter solutions. At best, they waste money – at worst, they risk failing when you need them most.
Free on-site visit
Arguably the most important part of the whole process, our free site survey allows us to meet you, analyse your infrastructure, and understand exactly what it is you want to achieve.
Personalised power audit
Your Carter Sullivan consultant will provide a ‘power audit’ report, detailing potential issues and opportunities. Any questions? We’re always just a quick call away.
Costs, benefits and efficiencies
Before installation commences, we’ll lay out the long-term financial forecast for your UPS solution – from the savings you’ll make to any potential servicing costs.
End-to-end sustainability
We’re proud to be at the forefront of the green revolution in UPS systems. You’ll get a full overview of your solution’s power usage, longevity, and eventual recycling.
In-house training and demos
We have our own on-site demo and training centre in Bedford, complete with batteries, bypass switches and fully operational UPS systems for you to interact with.
Rapid emergency response
We offer 24/7/365 support for any UPS issues. Depending on your maintenance contract, our guaranteed emergency response time ranges from next day to under four hours.

Our partners

We’ve long maintained strong partnerships with the leading manufacturers of UPS systems. These brands trust in our expertise in maintaining their products.

Our accreditations


“Very good experience. Carter Sullivan went above and beyond decommissioning our old APC UPS. They carefully dismantled each of the racks, as our lift was too small to take the whole thing out in one go.”

Our process

Here’s what our standard UPS installation process looks like, from end to end. Bear in mind, however, that we devise a bespoke solution for every client. No two projects have the same life-safety requirements, so we never take a one-size-fits-all approach.

Site visit
Our free on-site survey occurs within a week of you contacting us. It allows us to understand the environment, the life-safety needs, and any future-proofing considerations.
Consultancy
We’ll present you with our ‘power audit’ report, and advise on the best solution to your UPS needs, in terms of price, size, power, efficiency and room layout.

Design
Once you’ve approved your UPS design, two pictorial layouts will be produced: a technical version for our engineers, and a more stripped-back version for you and your team.

Installation
Installation usually takes place three to four weeks after making initial contact with us (although delivery times for certain products may extend this timeframe). In the event of an installation requiring a brief downtime, we’ll work to align with your schedule.

Maintenance and aftercare
A tailored maintenance package ensures the UPS protecting your colleagues, clients or tenants is itself protected. Performance is optimised, downtime is avoided, and savings are made.

Sustainability
We’re proud to be at the forefront of the green revolution in UPS systems. When your solution eventually reaches the end of its life – many years from now! – we’ll decommission and recycle it.
