What Stelrad does
Stelrad Group plc is Europe's leading specialist manufacturer of steel panel radiators and heat emitters, headquartered in Newcastle upon Tyne, UK, and listed on the London Stock Exchange (ticker: STLR) since November 2021. The group operates through five core brands — Stelrad, Henrad, Termo Teknik, DL Radiators, and Hudevad — which are tailored to specific channels and regional end-markets. Its product portfolio spans 178 ranges including standard, premium and low surface temperature (LST) steel panel radiators, towel warmers, decorative steel tubular radiators, steel multicolumn radiators, aluminium radiators, and hydronic, hybrid, dual fuel and electrical heat emitters, the latter including low-temperature designs compatible with heat pumps and renewable energy sources.
Manufacturing is conducted across four sites in the UK (Mexborough), the Netherlands (Nuth), Turkey (Çorlu) and Italy (Moimacco), with combined capacity of approximately six million radiators per year, and additional distribution facilities in Poland and Denmark. Sales personnel cover five further countries. Stelrad serves over 500 B2B customers across more than 40 countries via a sales-led, specifier-driven go-to-market that combines direct enterprise relationships with specialist distributor channels; pricing is negotiated B2B rather than list-based.
The business generated £279.6m of revenue in FY2025 (down 3.8% YoY), with an adjusted operating margin of 11.6% (up from 10.8%) and a 1.16x leverage profile (£51.2m net debt). The group holds a 24.2% volume share of the European steel panel radiator market excluding Russia and Belarus, and is the #1 player by volume in seven European countries.

Stelrad competitors and assessment
Company assessmentBroad incumbents
- BDR Thermea Group: European heating solutions group (Baxi, De Dietrich, Remko) focused on boilers, heat pumps and integrated systems. Adjacent to Stelrad with overlapping distribution and end-customers but not a direct radiator specialist.
- Glen Dimplex Group: Irish-headquartered manufacturer of electric heating, radiators and renewable thermal solutions. Overlaps with Stelrad's electric radiator range but is broader in scope, covering storage heaters and heat pumps.
- Ideal Heating (Bosch): UK-based boiler and heating manufacturer, part of Bosch Home Comfort. Competes with Stelrad indirectly through heating system packages but does not focus on the radiator category at Stelrad's scale.
Emerging players
- Fondital: Italian aluminium and steel radiator producer focused on the Mediterranean market. Smaller than Stelrad but a meaningful regional competitor in Southern Europe where Stelrad operates through DL Radiators.
Direct peers
- Rettig Group (Purmo): Finnish family-owned group and Europe's largest radiator manufacturer, owning brands including Purmo and Radson. Direct competitor to Stelrad in steel panel radiators across the Nordics, Central Europe and Eastern Europe.
- IRSAP: Italian designer radiator manufacturer with a broad portfolio of steel tubular, decorative and heated towel rail products. Comparable to Stelrad's DL Radiators and Hudevad design-led ranges across Southern Europe.
- Zehnder Group: Swiss manufacturer of radiators, towel warmers and indoor climate systems. Overlaps directly with Stelrad's premium and design-led radiator ranges, particularly Hudevad and DL Radiators, across Western Europe.
- Vasco (Rettig): Belgian design-radiator brand owned by Rettig, specialising in steel tubular and towel radiators. Closely comparable to Stelrad's decorative and towel warmer categories in Benelux and wider Western Europe.
- Arbonia AG (Kermi): Swiss-listed building products company with a sizeable radiator division including the Kermi brand (Germany) and Vasco. Competes head-to-head with Stelrad in steel panel radiators and design radiators across DACH and Benelux.
- Jaga Group: Belgian radiator manufacturer known for low-H2O and heat-pump-compatible emitters. Directly comparable to Stelrad's LST and heat-pump-ready product lines, competing across Benelux, Germany and the UK.
