ERG Scotland

What ERG Scotland does

ERG Scotland Limited (Company No. SC195590) is a privately held Scottish home improvement installer headquartered in Invergordon, Scotland, operating continuously since 1974. The company designs, supplies, and installs made-to-measure double-glazed windows, doors, conservatories, home extensions, and replacement roofs for residential customers, primarily across the Scottish Highlands and Inverness region. Core product lines include Extreme UPVC windows (A+ rated), Eclipse Aluminium slimframe windows, Envisage Flush casement windows, composite/UPVC/aluminium doors, bi-folding and French doors, conservatories, tiled and glass roofs, lantern roofs, flat roofs, and roofline systems, all manufactured in the UK. Differentiated features include multi-point locking, GRP-skinned composite doors with 25–35 year lifespans, aluminium windows rated for 30–40 years, and U-values as low as 1.2 W/m²K.

ERG Scotland generates revenue primarily through one-time, project-based installation contracts priced on a quote basis and dependent on specifications, dimensions, materials, and installation requirements; a secondary commission stream arises from FCA-regulated credit brokerage through a finance partnership with Novuna Personal Finance (trading style of Mitsubishi HC Capital UK PLC). Distribution is omnichannel within a regional footprint: customers engage via an Invergordon retail showroom, in-home consultations by field sales representatives, online quote requests, and an online Door Designer configurator. Marketing emphasises 50 years of heritage, energy efficiency (A+ ratings, reduced heating costs), comprehensive guarantees covering moving and non-moving parts, a 14-day price promise, and flexible finance options to broaden access. Customer concentration is entirely on individual residential homeowners, with named testimonials spanning period-property renovations, 1930s home extensions, and Scottish bungalow roofline upgrades. No AI/ML capabilities are disclosed; technology differentiation rests on physical product engineering and aftercare guarantees rather than software.
