What Energlaze does

Energlaze is a privately held Irish home energy upgrades installer headquartered in Wexford, Ireland, founded in 2012. The company designs, supplies, and installs retrofit and replacement energy efficiency products for the Irish residential, commercial, and agricultural markets, with a portfolio spanning insulated glazing, uPVC windows, composite doors, solar PV systems, heat pumps, and multiple insulation categories (external wrap, cavity wall, attic). Its proprietary technology includes the trademarked Low-E-Plus™ and Low-E-Plus2™ heat-retaining glass units (U-values of 1.0 and 0.9 W/m²K respectively) and a partnership with AGC for Fineo vacuum glazing (0.7 W/m²K at 7.7mm thickness for heritage timber frames). The company acts as a SEAI-registered One Stop Shop, managing grant administration, technical assessment, installation, and project management for whole-home renovations targeting a minimum B2 BER rating.

The company's product stack is anchored by tier-one technology partnerships rather than in-house R&D across hardware: Huawei FusionSolar inverters, Luna2000 modular LiFePO4 battery storage, and per-panel optimisers for solar PV; Mitsubishi Ecodan air source heat pumps; Jinko all-black solar panels (25-year warranty); Palladio composite doors; and Guardian Warm Roof conservatory conversions. Energlaze's core technical differentiator is its proprietary low-emissivity glass coatings combined with retrofit-first installation methods that preserve existing frames, reducing customer disruption and project cost versus full window replacement. Commercial solar PV is offered up to 1MW system size with SEAI non-domestic grants up to €162,600.

Energlaze operates a direct-to-consumer, sales-led go-to-market model through a nationwide field network of energy consultants who conduct free in-home surveys and produce no-obligation quotations. Revenue is generated almost entirely through one-time installation projects priced per quote, with grant values (up to €32,000 for One Stop Shop packages, €12,500 for heat pumps, €1,800 for residential solar, €8,000 for external insulation) typically deducted upfront. Pricing is not publicly disclosed on the website. The company supplements direct lead generation with content marketing, SEO, organic social (Facebook, Instagram, LinkedIn, YouTube), press coverage in Irish national media, and a referral partnership with Bord Gáis Energy. Marketing reach was materially extended in 2025 through a featured appearance on RTÉ's Room To Improve programme for the Julian Benson CF Foundation project.
