Stelrad has been manufacturing radiators since 1936, beginning life as a small British engineering business committed to producing dependable heating products for homes and commercial buildings. From our earliest steel panel radiators to today’s advanced designer and energy‑efficient ranges, our story has been shaped by craftsmanship, innovation and a dedication to quality that has lasted for more than 90 years.

Our headquarters remain in Rotherham, South Yorkshire, close to where the business was originally founded. Over the decades, Stelrad has grown from a local manufacturer into the largest radiator supplier in the UK and Ireland, trusted by millions of households, installers, merchants and national housebuilders.

We now employ over 500 people across our production plant, National Distribution Centre, engineering teams and customer support departments. Our Mexborough manufacturing site has been a cornerstone of British heating production for generations, combining traditional expertise with modern technology to deliver over 2.5 million radiators every year.

Quality and safety have always been central to our heritage. Every Stelrad radiator is fully tested and certified to EN442, the European standard for radiator performance, ensuring consistent heat output, efficiency and durability. We also provide a Declaration of Performance (DoP) for every product, giving customers complete transparency and confidence in the technical standards behind their purchase.

Throughout our history, we’ve continually expanded our product offering. Today, we provide one of the most comprehensive energy‑efficient and sustainable heating solutions. Our radiator ranges include:

• Standard steel panel radiators

• Decorative and coloured radiators
• Steel column radiators
• Cast iron column radiators
• Towel rails

Our heritage is built on reliability, and that continues today with sector‑leading delivery performance, offering 99% of orders delivered within 72 hours across the UK and Ireland. Customers choose Stelrad for our combination of choice, quality, reliability and availability, values that have defined our brand for nearly a century.
