Birmingham-based energy consultants committed to sustainable business transformation
Founded in 2012, marsh-starling emerged from a straightforward observation: too many businesses were struggling to navigate the complex landscape of energy efficiency and renewable adoption without impartial guidance.
What began as a small consultancy serving local Birmingham businesses has grown into a recognised regional practice, though our core principle remains unchanged. We believe sustainable energy decisions should be grounded in rigorous analysis rather than sales pressure or assumptions.
Our team combines engineering expertise with commercial awareness, ensuring that every recommendation we make balances environmental impact with practical business considerations. We have never sold energy products or received commissions from suppliers, preserving the independence that our clients depend upon.
Principles that guide every engagement and recommendation
We maintain strict separation from product suppliers and installers, ensuring our advice reflects your interests rather than commercial relationships.
Every recommendation is supported by data and analysis. We quantify expected outcomes and acknowledge uncertainties rather than offering vague promises.
Theoretical perfection means little if it cannot be implemented. We focus on solutions that work within your operational constraints and budget realities.
We explain our methodology, share our assumptions, and welcome scrutiny. Clients who understand our reasoning make better decisions.
A structured methodology that delivers consistent, measurable results
We begin by understanding your current energy profile, business objectives, and constraints. This includes site surveys, utility analysis, and stakeholder interviews to build a complete picture.
Using industry-standard tools and our accumulated regional data, we model potential interventions and their expected impacts on energy consumption, costs, and carbon emissions.
We synthesise findings into a prioritised roadmap that sequences interventions for maximum impact while respecting capital constraints and operational continuity.
For clients who require it, we provide oversight during implementation, from tender management and contractor selection through to commissioning and performance verification.
Energy systems require continuous attention. We offer monitoring services and periodic reviews to ensure your investments continue delivering projected returns.
