Frontline Energy team

“Frontline Energy was founded in 2007 to provide an end-to-end maintenance and energy management solution for the built environment.”

Frontline Energy was founded in 2007 to provide an end-to-end maintenance and energy management solution for the built environment. Ireland’s most experienced district heating provider, we design tailored solutions for our customers that focus on enhancing their business performance and reducing their running costs.

Energy is quite possibly the most valuable commodity on the planet. Without it, nothing else in our everyday lives can function or be produced. So we see it as our responsibility to advise our customers on ways of minimising their energy use, costs, and environmental impact.

From District Heating systems to Lean Heat, HVAC to Energy Consultancy, our diverse range of services coupled with our expertise is focused on implementing sustainable energy solutions and reducing carbon emissions for some of Ireland’s most recognisable companies.

At Frontline Energy, we directly employ and train our own plumbers, electricians, service technicians and energy consultants. This enables us to guarantee a high level of service within a fast response time, while our 24/7 help desk acts as a single point of contact for all of our energy customers.

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.

Case Study

Heuston South Quarter Biomass Feasibility

Due to the volatility in the gas markets Frontline Energy were engaged to perform a feasibility study to look at firing a previously unused biomass boiler that was installed when the building was first constructed but never ran because commercial gas was historically cheaper.
