About Us

We are a fire engineering company specialising in design, project management, installation and maintenance of fixed fire protection systems. Our projects range from individual dwellings and services to large scale distribution warehouses. J&J operate throughout the UK and Ireland.

What we do

J&J Design Ltd began over 25 years ago as a subcontract installation company. The number of clients steadily grew, leading to the company bringing in new staff with expertise within the sprinkler protection industry.

By 2016 the company had grown substantially and the variety of work increased to cover many services and products. J&J Design was rebranded J&J Fire Engineering (trading as J&J Design Ltd) to better reflect the work undertaken.

J&J Fire Engineering is now regarded as a key player in the fixed fire protection industry with an exemplary catalogue of clients and projects that has helped cement the company’s reputation as an experienced and trusted firm.
