H&A Group

H&A Group is a family-owned, multi-disciplinary business delivering mechanical, electrical, renewable energy, and property maintenance services across Ireland. Founded in 1993, the company has grown to employ over 200 people and is driven by strong values, innovation, sustainability, and a commitment to quality, safety, and community impact.

Originally established by Hugh and Anne McWilliams as a mechanical services provider, H&A has strategically diversified in recent years to include electrical services, renewable energy solutions, and property maintenance. This expansion has enabled the business to support a broad and growing client base, delivering everything from private one-off installations to large-scale social housing projects, as well as commercial, industrial, and government schemes focused on tackling fuel poverty.

From initial design and installation through to ongoing maintenance and repair, H&A delivers a fully integrated, end-to-end service. As a family-owned business, the team takes pride in a hands-on approach and a “right first time” philosophy, ensuring every project is completed to the highest standard while building strong, long-term client relationships.
