From Eco Pioneer to Social Media Star
Judith Leary-Joyce, a 76-year-old author, grandmother, and dedicated environmental advocate, has lived in her St Albans, Hertfordshire home since 1979. Her commitment to sustainability began in the 1970s, evolving from vegetarianism to veganism, driving an electric vehicle, favoring trains over flights, and avoiding single-use plastics.
Inspired to share her knowledge with younger generations, she posted an Instagram reel showcasing her eco-upgraded home. The video exploded in popularity, boosting her followers from 311 to 30,000 in the first month and now standing at 176,000. Her family affectionately calls her InstaGran.
Homeownership Journey and Challenges
Judith purchased the property for £27,000 while earning £1,100 annually as a qualified teacher. Back then, her income did not factor into the mortgage calculation—limited to 2.5 times her then-husband’s salary—because she was a woman and could not sign documents without his presence. She now co-owns it with her second husband of 43 years, with the mortgage fully paid off after 25 years at a 16% interest rate.
£25,000 Retrofit Transforms Energy Use
The couple invested £25,000 in a full retrofit, insulating the home, making it airtight, adding ventilation, a heat pump, and solar panels. Energy consumption dropped dramatically from 25,500 kWh annually—for the house and car—to just 6,000 kWh. The home stays warmer, and experts estimate its value exceeds comparable non-retrofitted properties by over 10%.
Solar panels now cover energy bills and car charging, achieving a 75% reduction in usage. Judith authored two books from this experience: Beginner’s Guide to Eco Renovation and What the Builder Won’t Tell You.
Influencer Rise Starts with a Dishwasher
Her influencer path began with a reel of her emptying the dishwasher, which garnered 5 million views. Despite brand deal offers, Judith prioritizes her message over monetization. She aims to show young people practical home upgrades, emphasizing function over aesthetics.
Self-taught through trial and error, she consults experts and challenges builders on topics like breathability and clay plaster for moisture control. Both daughters live nearby—one opposite, one around the corner—allowing easy grandkid visits.
Personal Touches and Favorite Spaces
The home reflects their lives with story-filled ornaments: singing bowls from Nepal, a wire tree from South Africa, a Bhutan painting, and a musical bird from Peru. Judith’s favorites include a sleek Louis XVI-style sideboard, a shell-shaped white leather sofa, and the extended family kitchen where she cooks amid loved ones.
Future Plans and Practical Tips
Upcoming upgrades include clay plaster in the bathroom for better moisture management with the heat recovery ventilation and a water conditioner against limescale. No major issues plague the old house post-retrofit.
Judith advises homebuyers: conduct a thorough survey including energy efficiency, understand every detail, check roof orientation for solar panels (south-facing ideal), and avoid overspending. For energy savings, open windows twice daily to expel moist air, preventing condensation and easing heating.
She calls it her forever home: “They will carry me out of here in a box!”
