HES Electrical Services Ltd., trading as HES Energy, was formed in 2001. We began as a small electrical service company but quickly expanded to provide plumbing services, ventilation services and renewable energy services also.

We serve home-owners, businesses and landlords in the mid-east region: Dublin and surrounding counties. Our team is friendly, informative and easily recognisable with our uniforms.

Our Experience

Our team has over 50 years combined experience in plumbing, over 25 years in electrical and over 15 years in ventilation services. We also provide the highest quality renewable systems service in Dublin. We can combine these skills to ensure that your needs are fully met, whatever the job.

Quality and Coordination

HES Energy has grown in response to the changing needs of our clients.
