Traditional Grandeur, Extended Heat Output
The Oversized Sovereign 4-Tube 30" Cast Iron Radiator takes one of our most popular heights and extends it for larger spaces—perfect for long walls, spacious interiors, and statement rooms where high heat output and timeless style are essential. Standing 30 inches tall, it fits neatly beneath most windows while delivering powerful performance and striking period detail.
Expertly cast in a European foundry using original late Victorian and Edwardian patterns, each oversized radiator is hand-assembled to order and finished to your exact specifications. Choose from a wide selection of painted colors, metallics, powder-coated finishes, or hand-polished options to complement both heritage properties and design-led modern homes.
For safe transport and easy installation, oversized Sovereign radiators are supplied in two or more sections, complete with joining threads, gaskets, a radiator assembly tool, and clear step-by-step reassembly instructions. Each unit is fully pressure-tested, backed by a 25-year guarantee, and designed for use with both hot water (hydronic) and steam heating systems.
Built using time-honored casting techniques and premium European materials, the Sovereign range is celebrated for its superior build quality, dependable performance, and authentic period charm.

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.
