"Frontline Energy has worked with Custom House Square Management Company since 2013. Frontline was instrumental in negotiating a significant six figure sum from Bord Gáis Heat for dilapidations. Since taking on the management of the District Heating at Custom House Square, Frontline has also secured a refund of €80,000 from BGE/Gas Networks Ireland, for overcharging on gas bills for sites charges. Frontline continues to assist the Owners Management Company with valuable, measured advice, and assistance and I have no hesitation in recommending Frontline to manage any District Energy Scheme."

Energy Innovation

We implement and service energy solutions and technologies that reduce carbon emissions and improve cost efficiencies, enhancing the business of our customers and the lives of end users.


Cleaner, more efficient means of powering and heating residential and commercial buildings will help to reduce consumer energy bills and the costs associated with disposing the waste created from its generation.

Climate Change

Identifying new energy technologies or improving efficiencies of current heating solutions will help reduce the level of carbon emissions into the environment that lead to climate change.

Reduced Air Pollution

Finding energy alternatives to fossil fuels to heat and power our homes and businesses will lower emissions of harmful gases like carbon dioxide.


With global energy requirements increasing, energy innovation is concerned with identifying means of energy production that are reliable and dependable enough to meet the needs of a growing population, and which are cleaner to generate and store.
