Radiator manufacturer Stelrad is expecting to report a 3% rise in adjusted operating profit to £32.5m when it publishes its annual results, in line with market expectations.

This would represent an adjusted operating profit margin of 11.6%, up from 10.8% in the year previously.

Stelrad, which manufactures and distributes central heating radiators, was issuing a trading update for 2025 ahead of reporting its annual results on 13 March.

The company said it had delivered a year of profit growth despite an “ongoing suppression of volumes” across its core UK and European markets.

Stelrad’s revenue for the year is forecast to be £280m, reflecting a small improvement in volumes in H2 compared to H1. Although overall volumes declined by 4% year-on-year, the company said it had seen “encouraging progress” in several of its markets.

“During 2025, Stelrad continued to demonstrate and enhance its operational excellence, underpinned by our core competitive advantages of a flexible, low-cost manufacturing footprint, outstanding customer service and unmatched product availability,” Stelrad chief executive, Trevor Harvey, commented.

“These allowed us to continue to deliver growth in operating profits and margins, despite the subdued market environment.

“While persisting market headwinds remain frustrating, our performance in the last year further evidences Stelrad’s ability to continue to deliver against our strategy irrespective of market conditions.

“The ongoing execution of our strategy underpins my confidence that Stelrad is well-placed to deliver sustained growth and, longer term, is incredibly well positioned to benefit from the eventual market recovery.”
