Energy Efficiency Surveys

A site visit by an experienced energy engineer

A site visit by an experienced energy engineer includes:

• A full walkthrough of the building to observe key systems and operational behaviours
• Review of existing energy data, controls, and maintenance records
• Identification of visible inefficiencies, equipment issues, and quick-win opportunities
• Application of sector-specific knowledge to assess building performance in context
• On-site discussions with facilities staff to understand usage patterns and constraints
• Optional photographic documentation to support findings and recommendations

This hands-on assessment ensures that every survey is grounded in real-world conditions and tailored to your organisation’s needs.

Data collection and analysis of energy use

During the site visit, our engineers gather detailed information to build a comprehensive picture of your building’s energy performance. This includes:

 
• Energy consumption patterns across key systems and zones
• Equipment performance and operational settings
• Occupancy behaviours and usage trends
• Review of existing energy data, controls, and maintenance records
• Identification of anomalies, inefficiencies, and areas for optimisation

Identification of low-cost and capital improvement measures

Our engineers highlight a range of potential interventions, from quick wins requiring minimal investment to larger capital projects that deliver long-term savings and sustainability benefits.  Recommendations may include:

• Low-cost operational changes such as control adjustments or behavioural improvements
• Upgrades to lighting, HVAC controls, or insulation with short payback periods
• Replacement of outdated or inefficient equipment with modern, energy-saving alternatives
• Capital projects such as boiler upgrades, renewable energy installations, or BMS enhancements
• Prioritised action plans based on impact, feasibility, and return on investment

Estimated energy and carbon savings

For each recommended measure, we provide clear estimates of the potential reductions in energy use and associated carbon emissions. This helps you understand the environmental impact of your choices and prioritise actions that deliver the greatest benefit.
 
Our estimates typically include:

 

• Projected annual energy savings (kWh or GJ)
• Associated carbon reductions (tonnes CO₂e)
• Indicative cost savings based on current tariffs
• Payback periods and return on investment
• Contribution to net-zero and ESG targets

Budget-level costings and payback periods

We include indicative costings and expected payback periods for each recommended measure, giving you the financial insight needed to prioritise actions and plan investments with confidence.
 
Our financial analysis typically includes:

 

• Estimated capital and operational costs for each intervention
• Expected annual savings based on current energy tariffs
• Payback periods and return on investment calculations
• Comparative cost-benefit analysis across multiple options
• Support for funding applications and business case development

Clear recommendations

The final report presents a concise set of tailored recommendations, designed to be practical, actionable, and aligned with your operational goals. Each recommendation is prioritised to help you focus on the most impactful measures first.
 
Our recommendations typically include:

 

• A summary of key findings and improvement opportunities
• Specific actions for operational changes, upgrades, or capital investment
• Estimated costs, savings, and payback periods
• Projected carbon and energy reductions

Alignment with funding criteria

Where relevant, our recommendations are mapped against current funding schemes and incentives, helping you unlock financial support for energy efficiency improvements and capital upgrades.
 
We help you:

 

• Identify eligible measures under local, regional, and national funding programmes
• Align recommendations with scheme requirements and application criteria
• Provide supporting evidence and documentation for grant submissions
• Highlight co-benefits such as carbon reduction, improved resilience, and social value
• Strengthen business cases for internal approval and external funding
