Meeting the Sustainability Criteria is an essential part of the UK’s renewable energy support scheme.

Our expert understanding of this process will help your project meet and exceed the necessary threshold, to ensure you qualify for full payments.

The importance of sustainability in the day-to-day management and operation of an AD plant is demonstrated in three key ways:

  1. Financial benefits: Ensuring your plant complies with the sustainability criteria and regulations that govern the renewable energy industry means you will benefit from the subsidiary regimes.
  2. Environmental impacts: Managing the impact on the environment is a primary goal for every AD facility and is something we can help you to achieve.
  3. Net Zero goals: To reduce your carbon footprint, we will work with you towards your goals and the targets laid down by governments.

Despite the numerous benefits, it can be a challenge for already busy AD plant operators to meet the ever-increasing sustainability criteria. We can support you with the administrative burden by guiding you through this process to help you achieve your sustainability goals.

Our extensive experience in accreditation delivery and ongoing compliance is demonstrated by a 100% record in achieving RHI and Feed-in Tariff (FIT) certification for 48 accounts. Ixora-managed plants consistently score highly in independent Ofgem sustainability audits. This highlights how we can put in place our tried and tested processes, so you can be confident that your plant meets its sustainability goals.
