Traditional Strength, Scaled for Larger Spaces
The Oversized Sovereign 6 Tube 26" Cast Iron Radiator brings classic Victorian styling and powerful heat output to a larger scale—perfect for expansive rooms, long feature walls, or open-plan interiors where performance and period character go hand in hand. With its substantial 6-tube design and balanced mid-height profile, this extended version delivers both impressive warmth and timeless appeal.
Faithfully cast in Europe using original late 19th-century patterns, each radiator is hand-finished to order in our workshop. Available in a wide selection of finishes—including painted, powder-coated, metallic, and hand-polished options—the Sovereign range combines robust construction with exceptional craftsmanship and customization.
To ensure safe and practical delivery, oversized Sovereign radiators are shipped in two or more sections and come complete with joining threads, gaskets, an assembly tool, and clear reassembly instructions. Fully pressure-tested to 8 bar, compliant with EN442 standards, and backed by a 25-year guarantee, this is a reliable, high-output radiator designed to make a statement.

Hand Polished Cast Iron Radiators

Hand polishing cast iron radiators is a very time consuming process. Each section is individually polished with a series of bespoke polishing wheels.
We only polish the visible areas - the front, the top and on the end sections but not on the back which would be placed against the wall.
