About us

Commercial engineers in the South East

With over 40 years' experience in the ventilation, air conditioning & electrical engineering industries, JJ Engineering Co. has grown steadily from a small concern into a thriving business.

About our business

The Company was jointly founded in 1972 by Fred Kidley and Peter Bailes. They started as two partners based from home, but as worked increased and they took on more employees, the company moved to its present address in Dagenham East, Essex. Paul Kidley, Fred’s son, started as an apprentice in 1982 and is now managing the business. Peter took early retirement in 1998, followed by Fred in 2010 at the age of 77. Business continues to improve and the workforce is still growing.

We feel that part of our success over the years is not only the continuity of management that a family business brings, but also that we have been able to maintain a loyal and hardworking workforce. Many of our employees have started with us as apprentices and remain with us to this day.

A complete engineering package

Today JJ Engineering Co. offers a complete package to our clients including design, installation and maintenance services for ventilation, air conditioning & electrical systems.

We mainly supply to the industrial and commercial sectors, and our clients include hotels, public houses, hospitals, offices and industrial premises. In recent years, with the increase in domestic air conditioning installations, we have developed our understanding of new technologies (i.e. inverter and heat recovery systems) and have branched into this area.

Experienced commercial engineers

We are members of the HVCA (Heating & Ventilation Contractors Association), and have passed their stringent inspection & assessment audits which include additional assessments of our health and safety provisions, giving us registration with the CHAS scheme national database. We are also members of NICEIC and are annually inspected by their auditing team. We have full REFCOM F Gas certification and are currently registered with Construction Line and are working towards full accreditation with them in the next few months.

We have recently achieved Business Partner status with Mitsubishi Electric and benefit from their wealth of experience and innovation.

Our customers are comfortable with the personal service they receive, and some of our clients have remained with us for over twenty five years. In today’s cutthroat business market, few companies can claim to have retained such loyalty.

We too have remained highly loyal to our business suppliers who, in turn, pass discounts and lower production costs on to us, enabling us to offer competitive prices to you. With this we are maintaining a cycle of success for all involved.
