Rebecca Boyle
BPharm (Hons) PhD
Accredited NatHERS & Scorecard Assessor
Thermal Performance & Energy Efficiency Specialist
Rebecca is an accredited NatHERS Thermal Performance Assessor, Residential Efficiency Scorecard Assessor and one of the first to be accredited to deliver NatHERS Home Energy Ratings for Existing Homes.
Originally trained as a pharmacist, Rebecca completed her PhD in pharmacy and ecology in 1999. In 2006, driven by a deep concern for climate change, she transitioned into the field of home energy—where she has since helped hundreds of households reduce energy bills, improve comfort, and make informed, sustainable choices.
Rebecca brings a blend of scientific rigour and practical insight to every assessment. She works closely with homeowners, architects, and designers to deliver NatHERS certificates for building approvals and provides tailored advice for improving the performance of existing homes. Her assessments are grounded in technical accuracy but always delivered with a focus on what matters most to her clients.

TESTIMONIALS
“Aspire Sustainability and Rebecca Boyle have made a big difference for our home. We were given simple tasks to make our home warmer. The steps have been incremental and affordable; and have made our home warmer by at least 8 degrees during winter before heating.”
“As an architect focused on sustainable design, I have the pleasure of working with Rebecca, whose expertise in optimising the energetic performance of buildings has been invaluable. Her in-depth analysis of thermal insulation, renewable energy integration, and efficient heating and hot water systems consistently results in homes that not only reduce energy consumption but also significantly cut costs for clients.
By fine-tuning energy models and recommending cutting-edge, eco-friendly solutions, she helps transform our designs into truly sustainable living spaces. Their proactive, data-driven approach ensures that every project aligns with our commitment to environmental responsibility while maximising savings for homeowners.”
“On moving back into my old weatherboard house in Upper South Hobart last year, I found it to be much colder than I had remembered it. I then commissioned Rebecca to do an energy audit and was delighted with the results. She’s extremely approachable, efficient and cost-effective. I would recommend her highly to anyone who is looking to passively warm up their house by identifying sources of drafts and blocking them up, and/or is looking for professional advice on solar panels and insulation options.”
