AGA Rangemaster – the UK group behind iconic British brands AGA, Rangemaster, Rayburn and Leisure Sinks – has achieved Gold status under the Future Net Zero (FNZ) Standard after cutting its verified carbon footprint by more than 50% in four years. 

Independently audited data shows total emissions of 4,360 tonnes CO₂e for the 2024 reporting year, down from a 2019 baseline of 8,746 tonnes CO₂e – a reduction of 4,386 tonnes. Exceeding the FNZ Gold requirement for a 30% or more carbon-reduction position the business firmly on the UN-backed Race to Zero pathway, a global campaign to halve emissions by 2030.

Operating from three British manufacturing centres – Leamington Spa for Rangemaster range cookers, Telford for AGA and Rayburn, and Long Eaton for Leisure Sinks – the group’s lower-carbon production helps kitchen studios, retailers, housebuilders, and developers shrink the embodied emissions of the products they specify and progress towards their own Scope 3 targets.

The reduction stems from an ongoing continuous improvement programme that reviews processes, energy use and equipment specifications across the group’s sites. Regular cross-site ‘Delivering Excellence’ meetings identified low-cost efficiency gains on the production lines, while a group-wide switch from fluorescent and high-intensity discharge lighting to LED technology lowered electricity demand. End-of-life plant and handling equipment were replaced with models designed to minimise fossil-fuel consumption, and real-time monitoring now highlights anomalies before they become energy drains.

“The FNZ Gold accreditation is proof, not promise,” said Ian Mincher, business excellence director at Middleby Residential – AGA Rangemaster’s parent company. “We set ourselves a challenge to make meaningful cuts and we have delivered – but Gold status is a milestone, not the finish line. Kitchens are the heart of a home, and our appliances, sinks and taps must be part of a genuinely low-carbon future.”

The FNZ Standard independently validates a company’s carbon footprint annually and recognises sustained progress. Gold status is awarded to organisations that achieve audited, year-on-year reductions of at least 30% against a verified baseline.
