Company History

Since its inception as a labour provider in 1995, ISTL has grown to become a full service mechanical and electrical contractor with an impressive portfolio of high profile projects.

Right from the outset, the ISTL team were prepared to work hard and follow employment where necessary, sometimes travelling as far afield as London from their Cardiff base. From the beginnings as an electrical company they branched out to offer mechanical services in 2000 and soon became very much in demand. The explosion in the development of luxury apartments in the Cardiff area ensured that ISTL were working flat out and the success achieved quickly established the company’s reputation as a reliable and highly skilled team.

Historically, the company has been active in the industrial and commercial sectors whilst being able to offer a number of specialist services to clients that place them in a highly competitive position. These services include installation of data and media cabling, air conditioning and CCTV and more, allowing ISTL to offer almost every conceivable building service.

ISTL’s experience in new build domestic projects such as Prospect Place, the major Bellway Homes
development in Cardiff Bay totalling over 900 luxury units, Admiral House for Midas Construction in Newport Rd, Cardiff and more recently the 304 luxury apartment contract for Bovis Lend Lease, St David's 2 Residential Development has provided the bedrock for the company to move into other markets.

Quickly noticing the market conditions and with great foresight ISTL, has built an extensive portfolio of projects in the assisted living sector for Jehu, Ty-Croes and most notably for Leadbitter Construction - bringing together the expertise gained from previous industrial, commercial and residential projects and giving the client and end users a safe and functional environment to care for and house the elderly and infirm.

More recent developments have seen movement in to the design and installation of sprinkler installations and the provision of sustainable energy and water with ISTL Green. Never losing sight of the client’s demands and offering vast project experience, ISTL can offer the most complete and professional building services package in the M&E market.
