Why choose us?
We are dedicated to building long-lasting relationships both within our company and with our clients, based on trust, integrity and a shared commitment to success.
TSL Contractors is a well-established SME which has been operating within the construction sector since 1979.
Founded on the Isle of Mull, we have built a strong reputation for delivering high-quality civil engineering and construction projects across the West Coast of Scotland and beyond.
Our operations are centred around Oban and Fort William but our project reach extends from Inveraray in South Argyll, to Inverpolly in Wester Ross.
Our ability to mobilise quickly across such a wide geographical area demonstrates both our capacity and flexibility to meet client needs across the West Highlands and Islands.
We employ a predominantly self-delivery model, with a direct workforce of approximately 150 skilled operatives, the majority of whom are based locally. This model is supported by a significant modern fleet of plant and equipment, allowing us to maintain high levels of control, quality and responsiveness across all projects.
Our proven track record, extensive resources and commitment to quality and safety position TSL Contractors as a trusted delivery partner for building, civil engineering and energy infrastructure projects of all scales.
Whether working on a one-off project or forging and nurturing long term working relationships, we strive for excellence and outstanding client care on each and every project we undertake.
