Protecting & connecting people for 25 years
We care about people and helping them protect their homes and businesses. Our expertise allows us to design, install, commission and maintain security and life safety systems that help keep people’s homes and businesses safe. Our team understand the different needs and systems that work best from securing a home to a large scale commercial premises.
Our history
RES Limited was formed in 1997 by Stephen Donaldson to meet the security and fire safety needs of clients that were having electrical works carried out by Richmond Electrical, Stephen’s original company formed in 1977 with the support of his wife Linda.As our client’s needs grew so rapidly, Richmond Electrical no longer reflected the full scope of the services we offered and expertise we had.
Since that time Stephens daughter, Leeanne, and son, Paul have both joined the company and our family business has developed to deliver solutions across many industries and sectors and we continue to evolve our services with new, ever-changing technologies to meet the needs of our customers.
Our commitment
The constant evolution across all the latest types of systems available and the need to solve ever more challenging solutions has allowed us to develop specialisms in fire safety, access control, security, CCTV and electrical systems. We are always striving to innovate and make best use of the technologies available to us as we offer our clients greater protection.

Our Reach
We work with clients across a wide range of sectors including residential, industrial, commercial, entertainment and healthcare. Our healthcare systems are in specialist care facilties and residential care homes throughout Northern Ireland.
