Callerton Enters a New Chapter:
Farewell to a Founder,
Welcome to a New Leader
​
Callerton, one of the UK’s leading independent kitchen manufacturers, is announcing a significant leadership transition that marks both a celebration of its heritage and a confident step into the future.
After more than four decades of passion, craftsmanship and commitment, James Herriot, co-founder of Masonhouse Manufacturing Ltd (trading as Callerton), is stepping back from the business and entering retirement. His shares have been acquired by the Stanger-Leathes and Short families, ensuring Callerton remains proudly family-owned and independent.
In an open message to the business and the wider industry, James shared:
James Herriot
“I’ve loved every minute of the last 40+ years. But now is the right time to prioritise my family, writing, and charity work. I remain incredibly proud of everything we’ve built, and I’m excited to see the business thrive in new hands. Callerton has always been about people, teamwork and long-term partnerships — that will never change.”
​
Driving Future Growth:
Ali Zair Joins the Leadership Team
​
As part of this transition, Ali Zair joins the senior leadership team. With a strong background in strategic growth, customer experience, and people development, Ali brings a fresh perspective and new energy to the business. Her career spans commercial, brand, and leadership roles across diverse sectors — from retail to consulting, including senior positions at World Challenge and the Forward Institute, where she worked with FTSE 100 companies and leading institutions.

“I’ve watched this business grow for a lifetime and feel both energised and humbled to now be part of its story,” Ali said. “Callerton is built on creativity, care and relationships. I’m here to listen, learn, and help the team build on that legacy as we shape the next chapter together.”
​
Design-Led.
British-Made.
Future-Focused
Product development at Callerton continues apace, with new ranges and innovations set to launch later this year. The brand remains committed to offering retailers and designers market-leading quality, flexibility and service — and is looking forward to continuing its long-standing partnerships with studios, suppliers and collaborators across the KBB sector.
​
This moment marks a proud continuation of Callerton’s journey: rooted in British manufacturing, driven by design, and focused on the future.
