What CI Group does
CI Group (legal entity Conservatory Insulations Northwest Limited) is a privately held UK home-improvement services company headquartered in Manchester, specializing in retrofit conservatory roof insulation and roof-replacement solutions for residential homeowners. The company positions itself as the UK market leader in its niche, claiming over 30,000 installations completed across UK Mainland over approximately nine years of trading, supported by a 4.9-star rating across more than 4,300 reviews and ISO 9001, BBA, TrustMark, Checkatrade, FairTrades, and HomePro accreditations.
The product platform is built on the proprietary C.H.R.I.S® (Conservatory Heat Reduction Insulation System), a six-layer quilt combining true aluminium foil, thermowadding membrane, and vapour control membrane with a purpose-built Internal Finish Board (IFB). The flagship is extended into two adjacent SKUs: SkyTherm®, a premium orangery-style roof replacement with Firestone EPDM and a glass lantern or rooflight; and ThermaTile®, a lightweight composite slate tiled roof (12 kg/m²) carrying a 40-year warranty. C.H.R.I.S® is the only conservatory insulation independently tested at Salford University's Energy House 2.0, where it demonstrated up to 82% improvement in roof U-values and a 32% reduction in heat transfer coefficient. Pricing is quote-based and not publicly disclosed; due to energy-saving classification, qualifying installations carry no VAT, and CI Group also operates as an FCA-authorized credit broker (Register no. 784951) offering up to seven years of interest-free finance.
The go-to-market is direct-to-consumer field sales: surveyors conduct nationwide home consultations, take measurements, and quote, followed by in-house installation teams. Marketing combines paid TV, broad social presence (Facebook, X, YouTube, Instagram, LinkedIn, Pinterest, TikTok), a Knowledge Hub content property, exhibitions such as the Homebuilding & Renovating Show, and heavy use of customer testimonials. The company operates as part of a family of related businesses that includes Elite Garden Studios, Tile Your Conservatory, Eton Property and Storage, and We Need Solar, with revenue not publicly disclosed.
