About Us

Established since 2003 and as an approved NIC EIC Company for over 10 years, we undertake a wide range of installations to keep all the project needs under one roof. This allows us to pass on discounts and give competitive rates whilst maintaining full control of the project to provide an unrivalled service to our clients.


We can design electrical installations to meet the most up to date Building Control requirements for Energy Efficiency and can offer the latest systems for Digital Television, Monitored Access Control, Intruder and Fire Alarm systems and TV-Tel Door Entry, etc.


The main benefit our clients have found valuable is that they only need one point of contact to resolve any issues across the board on projects.


In the last 13 years we have completed over 60 new build residential developments in London ranging from 6 to 140 units. A vast majority of these we still maintain for our Clients. We have also completed a wide variety of large commercial office and retail fit outs. Being able to undertake works from early design, installation of site temps and welfare facilities to complete project delivery, on time and on budget. This is what drives us and we are proud of the fact that we have never missed a deadline. Something we believe all our clients deserve!


We have gathered together a great team and are always looking to supply our services to new clients.
