What The Radiator Company UK does

The Radiator Company UK is a UK-based specialist retailer of designer radiators and heated towel rails, operating as a trading brand of IRSAP UK Limited, a subsidiary of Italy's IRSAP Group. The company sells a portfolio of 52+ designs spanning column, modern designer, traditional, flat fronted, tube, and curved formats, manufactured in cast iron, steel, and aluminium, with both wet-system and electric variants. Signature lines include the Ancona column range, the Linton cast iron range (BS EN442 / UKCA certified, 2-3 column, 4 heights, up to 40 sections), and the Linton Towel Rail collection. Customers can specify bespoke dimensions, 188+ RAL colours, and special finishes (Polished, Burnished, Antique Brass, Galvanised Copper) via a made-to-order service.

The business runs a direct-to-consumer e-commerce model via its website, supported by physical showrooms, phone-based sales (01342 302250 / 01342 305555), and content marketing through a 48+ piece Advice Centre. Revenue is generated from one-time hardware sales priced per unit (e.g., Linton Cast Iron from £191.12, Linton Towel Rail from £1,624.90, Cylinder Valves from £165.98), with Klarna financing available to spread cost and free mainland UK delivery on orders over £60 inc VAT. Customer-facing tools include a BTU Calculator and a Radiator Builder for custom configuration, with minimum 10-year guarantees on core products.

The customer base is residential UK homeowners, including a secondary segment of period-property owners undertaking heritage renovations, with no disclosed enterprise, trade, or B2B accounts. Operations are limited to the UK market (mainland England, Wales, and Scotland for free delivery; Northern Ireland and offshore islands at surcharge), with products over 2200mm not shipped off the UK mainland. The 25-year UK heritage combined with the IRSAP Group's 60+ year Italian manufacturing pedigree positions the business as a mid-market designer radiator specialist rather than a budget or premium-luxury player.
