Key Takeaways
- Mykor has raised £4 million in a round led by Clean Growth Fund, bringing total funding to £7.5 million, to scale its mycelium biofabrication platform for low-carbon construction products.
- The round included the British Business Bank's South West Investment Fund via The FSE Group, Green Angel Ventures, and Innovate UK's investor partnership programme.
- Mykor's MykoSIP partition wall delivers approximately 23kgCO₂e per m² in carbon savings versus incumbent systems, uses 90% less water and 40% less electricity than polystyrene counterparts, and stores biogenic carbon.
- The company has secured two offtake agreements worth a combined £338 million with UK and European contractors and is already delivering live construction projects.
- The funding supports production scale-up ahead of the UK Future Homes Standard (2027) and EU Energy Performance of Buildings Directive requirements.
Mykor Raises £4 Million to Scale Mycelium Construction Materials Platform
Mykor, a biotechnology company that grows low-carbon construction products from agricultural and industrial waste using mycelium biofabrication, has completed a £4 million funding round. The raise was led by Clean Growth Fund, with participation from the British Business Bank's South West Investment Fund via The FSE Group, Green Angel Ventures, and Innovate UK's investor partnership programme, bringing total funding to £7.5 million.
The company focuses on the industrialisation challenge in low-carbon biomaterials: manufacturing construction products at commercial scale from biological waste streams while meeting fire, acoustic, and performance standards required by mainstream construction supply chains.
“We've built Mykor around the idea that decarbonising construction cannot come at the expense of cost, performance or practicality. The challenge has never just been inventing a biomaterial — it's been manufacturing these systems at industrial scale and integrating them into real construction supply chains. This funding allows us to scale that model further alongside major contractors and manufacturing partners globally,” said Olivia Page, CEO and Co-founder of Mykor.
How Mykor's Biofabrication Process Works
Mykor's process combines engineered mycelium strains, green chemistry additives, and closed-loop automated manufacturing to grow construction products from agricultural and industrial waste within days. The company operates as a technology and process platform rather than a single-product manufacturer, enabling contractors and manufacturers to integrate its biomaterials into existing production lines. This model allows scale-up through existing industrial infrastructure rather than requiring new centralised manufacturing capacity.
Mykor's first product, MykoSIP, is a preassembled partition wall system that delivers an estimated carbon saving of approximately 23kgCO₂e per m² compared to incumbent systems — at least 50% lower, with additional benefit from biogenic carbon storage — while maintaining comparable thermal and acoustic performance. The panels use 90% less water and 40% less electricity than polystyrene counterparts, and unlike synthetic insulation products, do not emit toxins as they degrade.
Commercial Traction and Use of Funds
Mykor is already delivering live construction projects and has secured two offtake agreements with UK and European contractors worth a combined £338 million. The new funding will support production scale-up and the establishment of a replicable manufacturing deployment model across key markets.
“Mykor addresses one of construction's most pressing challenges: reducing embodied carbon without adding cost or complexity. Their solution integrates seamlessly into existing building practices and is cost-competitive with conventional materials,” said Susannah McClintock, Investment Partner at Clean Growth Fund.
Regulatory Tailwinds Driving Demand
The raise comes as building standards in the UK and EU tighten on energy performance and embodied carbon. The UK Future Homes Standard requires all new homes to be highly energy efficient from 2027, while the EU's Energy Performance of Buildings Directive mandates zero-emission new buildings and large-scale retrofit. The built environment accounts for approximately 39% of global emissions, with around 11% from embodied carbon in materials and 28% from operational energy use.
