Judith Leary-Joyce

Judith Leary-Joyce – climate advocate and Author

Judith Leary-Joyce is a powerful voice in the UK’s sustainability movement who proves that climate action begins at home. Judith has been an eco worrier and eco warrior, since the early 1970s. For decades, she has searched for the next step in climate action. She has embraced plant-based eating, rewilding, sustainable travel, preloved shopping and minimal plastic consumption. Retrofit is the most recent discovery that has quickly become transformative.

Her life mission is to help others explore how they can support the damaged planet, contributing to the solution, rather than be part of the problem.

Before retirement, Judith worked for 20 years in Leadership Development, and this showed her that everyone has a core talent with multiple applications. When people identify this talent, they can use it for good at work, at home and for the planet. She enjoys working with groups – large and small – to identify that talent and how it can be used to support environmental change.

From Eco Worrier to Green Mission

What began as a personal project has grown into a mission. Judith is determined to inspire and enable others to green their lives, whether that is changing shopping habits or improving their homes. She speaks passionately about the responsibility we carry for “all the grandkids to come” and believes individuals and homeowners hold far more power than they realise.

Her work has earned national recognition. Judith is included in the Top 100 most influential UK voices shaping conversations and driving change across the built environment. She has been named Home Sustainability Advocate of the Year by the

UK’s Build Magazine Award for three consecutive years, was Highly Commended by BBC Three Counties Radio at the Making a Difference Awards and has been named in the Built List: the Top 100 Influencers in the Built Environment.

These accolades reflect her credibility, persistence and ability to translate green living in all its forms into a language people can understand and trust.

Author of Practical Self Development and Eco Renovation Guides

In support of her leadership work, Judith wrote The Psychology of Success where she identified the common behaviours that enable people to adapt to circumstance and be successful.

During her own retrofit, Judith longed for a clear, honest guide written for beginners. When she couldn’t find it, she wrote it.

Her book, Beginner’s Guide to Eco Renovation, is written in her natural, accessible style. It covers the essentials homeowners need to know to achieve the best outcomes, without overwhelm or jargon. The book empowers readers to ask better questions, make informed decisions and avoid costly mistakes.

At the end of 2025, she published What the Builder Won’t Tell You, a practical and candid guide that covers everything from choosing the right builder to handling waste responsibly and avoiding landfill. The book reflects her commitment to transparency and to helping homeowners feel confident throughout the renovation process.

Together, her books position Judith Leary-Joyce as both a relatable and trusted guide in the green living space.

Engaging, Conversational Speaking Style

Judith Leary-Joyce is known for her conversational speaking style. She connects quickly with audiences because she speaks directly to the challenges they face. She shares stories from her own experience, including the mistakes, the frustrations and the lessons learned along the way.

Her talks are practical, motivating and grounded in real-life results. Audiences leave with clarity about how they can make changes in their own lives and an enthusiasm to begin their own journey.

She speaks to:

• The ‘climate concerned’ who want to be part of the solution
• Sustainability-focused organisations
• Built environment professionals
• Community groups and climate networks
• Businesses seeking practical climate action stories

A Strong Digital Voice for Green Living

Judith’s influence extends far beyond the stage. With 175,000 followers on  Instagram, where her family affectionately call her “InstaGran”, she shares insights on green living, retrofit and natural building materials.

Her content combines education with personality, making sustainable living feel achievable rather than overwhelming. She also writes a regular blog, is building her presence on YouTube and continues to give talks that support others in developing their own green journey.

Her platform demonstrates that sustainability is not a trend for her. It is a lifelong commitment.
