About Us

QDP has been in existence for more than 23 years and has developed two focus areas:
- Consulting Electrical Engineering
- Specialist lighting design.

As Consulting Electrical Engineers, we are able to assist in all aspects of electrical and electronic design, however to provide both of the above services, we employ staff with qualifications in architecture and electrical engineering.

As part of the lighting design service we can evaluate new and existing lighting installations and then provide alternative, more efficient lighting systems, together with the capital costs, pay back periods, energy savings, etc.
