Case Studies

Evidence of outcomes

A good case study is evidence. It shows how decisions were made, what was delivered and what changed as a result.

Estate Asset Intelligence & As-Built Validation Study

Challenge

New leadership inherited a complex estate with inconsistent records and limited confidence in what equipment was actually installed, what condition it was in, and whether drawings reflected reality. They needed a rapid, structured baseline to regain control, prioritise risk, and plan next steps

Our Approach:

  • Surveyed 23 district plantrooms across the estate with a consistent methodology

  • Captured asset data to sub-asset level (manufacturer, model, serials, ratings, key attributes, photos as required)

  • Conducted drawing validation against site conditions and identified discrepancies

  • Produced as-built drawing amendments where required to reflect services and plant layout accurately

  • Applied RAG condition grading during the walkdown to highlight immediate issues, emerging risks, and priority assets

  • Collated findings into a structured asset intelligence output suitable for handover to estates teams and leadership review

Outcome

  • Delivered a verified baseline of plant and assets across the estate, giving leadership clarity on “what’s really out there”

  • Updated drawings to reflect as-built conditions, reducing reliance on outdated or incorrect information

  • Provided condition and risk visibility through RAG grading, enabling prioritised maintenance and investment planning

  • Improved traceability and future planning capability through structured sub-asset level capture

Result

The estate moved from uncertain records to a clear, evidence-based understanding of its plantrooms, with validated documentation and prioritised risks enabling confident decision-making, improved maintenance control, and a practical foundation for lifecycle and CAPEX planning.

Renewables Feasibility Study Client

Approved premises facility with high energy consumption

Challenge: Evaluate viability of solar PV, BESS, and backup generator for energy efficiency and resilience.

Our Approach: Conducted non-intrusive data logging for 118 hours to capture load, phase balance, and consumption metrics Analysed voltage stability, peak demand, and annual projections Evaluated system options including G98-compliant PV, Li-ion BESS, and diesel generator Calculated financials, CO2 savings, and compliance with BS 7671 and PAS 63100:2024

Outcome: Recommended 11 kWp PV with 7-year payback and 90% self-consumption Suggested 38 kWh BESS for 4-6 hour backup and 67% ROI Identified phase imbalance for 12-15% bill reduction via <£1000 fix Result: Delivered study in 7 days post-P.O.; client achieved required outcomes plus additional savings from phase correction.

Lifecycle Feasibility Study Client

Industrial production facility with aging heat pump system

Challenge: Should they invest in a repair (£28k) or replace the system (£50k)?

Our Approach: Surveyed system condition and reliability history (Gathered from CAFM) Calculated efficiency deltas between old vs. modern units Collected warranty periods and service intervals for both options Calculated energy and running cost forecasts over 5 years

Outcome: Replacement would reduce monthly energy usage by 22% Manufacturer warranty + maintenance bundle lowered exposure Payback < 3 years versus repair Result: Client opted for a full system replacement, which we helped specify and procure. Delivering savings and long-term resilience.
