There are no one-size-fits-all solutions

Optimum experience, Optimum results

A true partnership approach

Specialist engineers at your service.

“OGS are proactive and responsive no matter what time of day or night. They have delivered everything they promised they would and more.”

Property Director – The Leadenhall building

We’ve come a long way since our business began in 1989. From being a small air conditioning and refrigeration company working for commercial customers, we have steadily evolved in response to customer demand.

We now specialise in business critical building services, focused on hard services: heating, air-conditioning, refrigeration, M&E (mechanical and electrical) maintenance and energy systems.

Hard services are crucial for the smooth operation of your business. Your staff and clients will only notice hard services when they fail.

It’s our mission not to be noticed – except for doing a really good job, providing seamless, responsive and proactive engineering services and building maintenance.

 

Total building services management

Our capabilities now include a comprehensive technical support service across London and the South East, delivered by our Specialist Services team, while our Corporate and Real Estate Services divisions provides in-house resident maintenance support during working hours, or even round-the-clock if required.

Our expert Data Centre technicians deliver 24/7 business critical maintenance and support to our clients.

Our Direct Services division takes care of all contracts large enough to require a dedicated Contract Manager. Finally, our Projects Division undertakes a variety of assignments ranging from life-cycle analysis and replacement to turnkey design and build projects.

 

We make business better

Better return on investment. Better equipment performance. Better energy efficiency.

At Optimum, we know every business needs something different. Our answer is to give our customers exactly what they need. Plus a bit more that they don’t yet realise they want: visibility, responsiveness and trust.

There are no one-size-fits-all solutions. We prefer the tailor-made approach. We aim to become culturally aligned to our customers. We don’t just win contracts and sit back. Instead, our management team works proactively on-site.

The others are good. We are Optimum.

A growing client base

We have an expanding portfolio of clients including Wellcome Trust, Savills, TelecityGroup, Financial Times, Lloyds Register, Disney, Telstra and Volta as well as many key mobile customers.

Our revenue has more than doubled over the last three years, with April 2016 audited accounts showing a turnover of over £50 million for the previous year.

Key people

Every member of our management team is extremely hands-on. It helps us get closer to our customers.

Our directors and managers know that getting on site regularly in person is the best way to keep everything running smoothly.

Community

We’ve always believed that it’s important to put something back into the communities in which we work.

Over the years, we’re learned that pursuing corporate and social responsibility within the community in a hands-on way is a much more effective approach than simply ticking boxes.

How we do it

At Optimum, we know every business needs something different.

We go the extra mile for our customers. We give them exactly what they need, but also a bit extra that they didn’t realise they want.
