Solar and roof refurbishment
Zestec has partnered with Kingspan, to combine roof refurbishment and on-site solar generation into a single coordinated solution
A funded, integrated solar roof refurbishment solution for commercial and industrial building owners.
Across the UK, ageing building stock, rising energy costs and tightening insurer and EPC requirements are converging. When addressed in isolation, these pressures can slow investment, increase operational risk and limit the ability to deploy on-site renewable energy.
Zestec and Kingspan transform this challenge into an opportunity, enabling buildings to unlock long-term energy value while strengthening asset resilience and performance.

The Zestec and Kingspan advantage
Delivered through a funded Power Purchase Agreement (PPA), the model aligns long-term energy generation with asset renewal. Building owners access clean, on-site electricity at predictable, below market rates, while significantly reducing the upfront capital typically associated with roof and solar upgrades.
As a global leader in high-performance insulation and roofing systems, Kingspan brings decades of technical expertise to the partnership. Its FM approved roof solutions are designed to deliver long term durability, fire safety and compliance, while providing a robust platform for integrated solar PV generation.
Zestec and Kingspan manage the entire project lifecycle, from feasibility and design through to installation, commissioning and long-term operations. This model simplifies delivery, reduces interface risk and ensures consistent outcomes with minimal disruption.
