Dominic O'Connor Ltd team

About Us

Specialist mechanical services built around real project needs

We help clients plan and deliver mechanical engineering work with a clear, practical process from the first enquiry through to completion. Our team focuses on understanding the building, the scope, and the site conditions before recommending the right approach, so the work is grounded in what the project actually needs. That keeps communication straightforward and helps clients feel confident about the next step.

Our approach is to stay organised, communicate clearly, and manage the work with care across each stage of the project. We handle specialist mechanical services for new build and live environments, and we also support decarbonisation and retrofit upgrades for existing buildings. The result is a service that is technical, dependable, and centered on delivering work that fits the project in front of us.
