Independent energy consulting rooted in engineering practice and Edinburgh's built environment
OnyxCliff was established in 2019 by engineers and sustainability advisors who had spent years implementing renewable projects across Scotland. We recognised a gap between high-level net zero commitments and the practical steps organisations needed to take.
Our team combines technical expertise in building systems, renewable integration, and energy modelling with direct experience navigating Edinburgh's planning environment and Scottish regulatory frameworks.
We start by understanding your current energy profile, operational constraints, and investment horizons. Then we model scenarios that balance capital cost, payback period, and carbon impact.
Our assessments include site surveys, utility data analysis, and stakeholder interviews. We deliver findings in formats that work for both technical teams and executive decision-makers.
Where appropriate, we support implementation by liaising with contractors, reviewing proposals, and monitoring early-stage performance against modelled expectations.
We base advice on measured data, validated models, and documented case studies, not vendor marketing or generic best practices.
Scottish climate patterns, Edinburgh planning policies, and regional grid characteristics shape what solutions are viable.
We model lifecycle costs, account for maintenance, and stress-test assumptions about energy price trends and incentive availability.
The energy transition unfolds over years. We support clients through multiple project phases, not just initial assessments.
Office buildings, retail premises, and mixed-use developments seeking to reduce operational carbon and energy costs.
Manufacturing facilities, warehouses, and logistics centres with high thermal or process energy demand.
Council buildings, educational institutions, and healthcare facilities navigating public procurement frameworks.
