About Integravolt

Precision energy consultancy backed by 15 years of electrical engineering excellence.

David Richards, Founder of Integravolt and Principal Electrical Engineering Consultant

David Richards

Founder & Principal Consultant

Integravolt was founded by David Richards to solve the most pressing challenge in modern construction: bridging the technical gap between rigorous energy compliance and intelligent system design.

With a career spanning over 15 years in the electrical engineering sector through Flexitest Ltd, David recognised a recurring failure in the UK market. As building regulations tightened and renewable technologies evolved, self-builders and renovation leads were being left to navigate a disjointed landscape of solar installers, heating engineers, and automation specialists who rarely spoke the same technical language.

From Compliance to Strategy

What began as a foundation in electrical safety and statutory testing naturally evolved into comprehensive energy consultancy. As the UK's 2026 Future Homes Standard redefines how we power our lives, Integravolt provides the steady hand required to steer complex projects from blueprint to reality.

We don't just install hardware; we deliver end-to-end energy strategy. Our expertise covers the critical technical milestones that determine a project's success:

  • Regulatory Precision: Navigating SAP calculations and Part L compliance with engineering accuracy.
  • Infrastructure Management: Managing complex DNO applications to ensure your site has the power it requires.
  • System Integration: Precision heat pump sizing and solar array optimisation that actually meets the thermal demands of the building.
  • Intelligent Automation: Designing smart-grid ready homes that utilise Octopus Agile automation to turn energy from a fixed cost into a managed asset.

The Integravolt Standard

David Richards' approach is defined by the belief that every kilowatt-hour matters. In a world of rising energy costs and climate accountability, "close enough" is no longer good enough.

Every cable size we specify is justified by load calculations; every renewable recommendation is backed by a decade and a half of electrical compliance work. We combine the foresight of a consultant with the pragmatism of an engineer, ensuring that your energy systems are not only compliant and sustainable but truly intelligent.
