About Diploma Plumbing
Located in Perth, Western Australia Diploma Plumbing has been working with the AGI group from 2011 when Frank DiCosta from AGI and Ron Grant discussed solar hot water for the perth builders market and sister company Diploma Solar was created to carry out installs for AGI builders. The relationship was started on a handshake and is still strong and still growing. Frank Dicosta and his team are market leaders and have strong support for their contractors. Diploma Plumbing and Solar are proud members of that group and look forward to working with Frank for many years to come.
Its our experience and dedication to our clients that sets us apart. Our MD Ron Grant has been in the plumbing business for 40 years and is current VP of Master Plumbers WA, a member of the MBA Safety Committee and represents MPA on the PIRG committee to government. Diploma Plumbing and Solar are a family owned and operate business with a dedicated staff and contractor base.
