About Reillys Renewables

Reillys Renewables is a family-run engineering business based in Glasgow, Scotland. We design and install solar photovoltaic roof arrays, modular battery storage, and air-source heat pump systems for homes across the west of Scotland. Our work weaves a high-performance, sustainable energy nervous system into the fabric of each property we touch — modelled down to the kilowatt-hour before a single rail is fixed.

This site is built for Glasgow homeowners and landlords who want to understand exactly what a renewable retrofit means for their property: the real yield of a JA Solar array on a west-facing roof, the buffer a EcoFlow Power Ocean battery gives against peak tariffs, and the low-carbon heat a Vaillant aroTHERM Plus heat pump delivers through a Scottish winter. It is a technical briefing, not a brochure — we show the specifications, the accreditations, and the deployment sequence so you can make an informed decision.

We are MCS certified, RECC members, and PAS203 retrofit compliant, with Gas Safe registration for the heating work that surrounds a full-system install. The business is owned and operated by the Reilly family — a small, accountable team of engineers and installers who have spent years fitting renewable systems into Glasgow's tenements, terraces, and detached homes. We believe smarter energy builds a better future, and that future is built one well-engineered home at a time.
