Innovative and transparent

Zestec makes a difference in the fight against climate change as an asset manager and developer of high quality new energy assets in the UK.

We are one of the UK’s most innovative asset management and development companies, with a team comprising a unique blend of financial, commercial, technical skills and over 30 years’ experience in renewable energy.

Our Mission

‘To create the value for UK businesses of power generating and storage technologies without the need for any capital expenditure’


The supply of fossil fuels is limited. Providing decentralised electricity generation, where power is generated at the point of use is as important for the UK’s future energy security as cutting carbon emissions.


Through constant innovation, strong partnerships and service clarity. By monitoring the latest investment and technology trends in our sector, we provide objective advice with optimal solutions

  • By providing access to funding solutions which enable businesses to generate and use their own clean, green electricity
  • By pioneering the development of commercial solar PV systems without reliance or requirement for government subsidies
  • By being aligned with all of our clients and stakeholders. Our approach only works for us if it works for them

Our Values

We have a common set of values at the heart of how we do business. Our values are not new, but define who are and guide our actions and behaviour. They influence the way we work with each other and the way we serve our clients.


Transparency is important to our clients and partners, we aim to be clear at all times, with an ethical approach to business.


Being easy to work with is crucial for our partners. We share clear criteria for the deployment of funds, helping our clients in assessing projects against these and then work together for successful deployment.


The renewables market is still young and will continue to develop. We will be at the forefront of new innovation, creating funding models for our partners and their clients.
