We 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-operations 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. Optimum Group Services provides seamless, responsive and proactive engineering services and building maintenance. Optimum Group Services started out as a small family-owned air conditioning company in 1989. We now deliver full building services, focused primarily on hard services. Our business turnover for the last financial year was 62 million. Whether you need a total building services solution, a maintenance contract or just a check-up, our core values of visibility, responsiveness and trust mean that we will deliver tailor-made services that exceed your expectations. (See the Services tab above for more information about our Building Services, Project Management, Mobile Services and Energy Services.) Each client wants something different from us. Our answer is to give them exactly what they want. 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.
