About TGA

Who Are TGA

TGA were established as T G Armstrong and Partners in Durham in 1962 and are now based in offices in Durham, Stevenage, Central London, Newcastle upon Tyne and Leeds.

We currently employ approximately 40 staff, all directly employed in the delivery of building services and spread across all of our offices.

Our experience covers many sectors including healthcare, education (schools, colleges and universities), leisure, commercial offices, historic buildings, museums and galleries, retail accommodation, laboratories, industrial developments and others.

We work on a wide range of project types including new build and refurbishments, procured via traditional design team led commissions and via design and build contractors.

As a wholly owned private limited liability partnership, each Director is actively involved in each project and is directly accessible throughout the course of all projects.

Our engineers strive to understand the needs and expectations of the Client, and to create environments for improved performance, comfort and efficiency.

Our success is born from our ability to adapt in a continually changing environment, staying abreast of the latest technology, legislation and, of course, by maintaining close relationships with our Clients.
