Quality Assurance

We strive to not only complete our client’s projects in a timely and cost-effective manner, but we also aim to build a relationship with them that is based on mutual trust and respect. In our experience, honest and open lines of communication lead to more seamless workflows and higher outputs which is beneficial to both client and contractor.

We implement a strict Quality Assurance System which all of our teams adhere to and we ensure that our clients internal needs are captured within our work systems and that Quality, Reliability and Performance are maintained throughout the duration of any project undertaken by us.

Copies of our tailored Quality Plans are issued prior to works commencement on all sites.

Our Values – Environment / Sustainability / People

At Gaffney Mechanical we are fully committed to not only meeting all our environmental and sustainability requirements, but we aim to exceed them whenever possible. We always ensure that any potential environmental impacts due to our actions while undertaking works are kept to a minimum and through our continuous investment in our people, our processes and our products we actively seek out opportunities for delivering improvements in this area wherever possible.

We believe in the process of designing or operating our systems with the aim of using energy and resources responsibly and with as little impact to the natural environment as is possible. We approach every project with a comprehensive and systematic plan which includes a provision to monitor and enhance our products and improve on our recycling efforts, waste reduction, materials management and prevent unnecessary pollution.

Our aim is to develop long term, close working relationships with our suppliers, our business partners, and our employees.

We care about our people and we believe that they are our most valuable asset. The health, safety and wellbeing of our staff and colleagues is always our Number One Priority.

Our value system is built upon mutual trust and respect and we aim to provide equal opportunity to all and to encourage and support every individual to develop both personally and professionally.

Each year through active or financial involvement, we like to support various selected initiatives – educational, charitable, sporting etc. that are important to our colleagues or our community in some way. We will look forward to continuing to develop our involvement with many more of these projects going forward.
