About Duncan Renewables - Renewable Energy in Yorkshire

Our History

Duncan Renewables is a division of Duncan Plumbing, Heating & Electrics Limited. We have been installing and servicing plumbing and heating systems for over 20 years and have installed renewable energy systems for over 15 years.

With our combined expertise in both heating and renewables, no one is better placed to help businesses and homeowners make the most of the Feed-in Tariff and Renewable Heat Incentives to protect you against escalating energy costs.

Our People

With origins as a plumbing and heating business, established by sole-trader Stuart Duncan, Duncan Renewables has rapidly grown into an award winning SME with over 50 employees. Mark Duncan, a chartered accountant, joined Stuart in the company having been previously employed at KPMG (Leeds and New York) and as a Finance Director with Lloyds Banking Group. Through the unique combination of Stuart’s technical plumbing and heating skills and Mark’s financial background, we are able to offer customers a complete service package.

We have a committed and reliable workforce who consistently produce high-quality workmanship. We also minimise our use of sub-contractors which enables us to offer service level reassurance and responsive flexibility.

Both the Feed-in Tariff and Renewable Heat Incentive are financial products and should be considered in the same way as any other investment. We have the financial knowledge to explain how you can make the incentives work for you both on a personal level, or for your business and through our established funding relationships we can ensure you achieve the right funding solution.

Our Future

As the renewable energy industry is such a relatively new market, it is constantly changing. With the ever changing incentive rates, Government policies, new product releases, fresh research papers, this industry keeps us on our toes! In addition to keeping our workforce fully trained, we work closely with BioVale (an innovation cluster that supports development of the region’s bio-based economy), and Mark is a member of the Green Economy Panel for Leeds City Region’s Local Enterprise Partnership (LEP).
