Energy Efficiency & Carbon Reduction
Reduce energy use, cut operating costs and improve building performance with practical, evidence-led energy efficiency support. We help commercial landlords, managing agents and occupiers identify quick wins and longer-term projects—focused on how your building actually operates, not just equipment replacement.
-
Building optimisation (controls, operation and maintenance) to unlock savings without unnecessary capex
-
Energy audits, feasibility and business cases to justify investment and prioritise projects
-
Optional design-to-tender and delivery support, with measurement & verification (M&V) to prove savings

Trusted building performance specialists for organisations across Greater London, the South East and the wider UK.
What is building energy efficiency support?
Building energy efficiency support is a structured approach to reducing energy consumption and carbon emissions by improving how building systems operate (HVAC, ventilation, lighting, controls), identifying and developing projects, and verifying that savings are delivered.
On this page, “energy efficiency” includes:
-
Operational optimisation (controls, schedules, setpoints, maintenance alignment)
-
Targeted upgrades (lighting, BMS improvements, plant improvements where justified)
-
Business-case development (capex planning, paybacks, risk and disruption management)
-
Verification (baseline + M&V to prove outcomes)
Who needs energy efficiency and carbon reduction support?
You’ll typically benefit if:
-
You’re seeing rising energy costs or inconsistent comfort complaints
-
You suspect systems are running longer than needed or fighting each other (heating/cooling overlap)
-
You want a clear pipeline of projects with realistic paybacks and minimal disruption
-
You manage multiple buildings and need consistent, portfolio-wide priorities
-
You want energy efficiency work aligned with TM44, ESOS or SECR obligations
What you get
Your scope can be light-touch or end-to-end, but a typical engagement includes:
-
A clear summary of where energy is going (energy balance / key drivers)
-
Prioritised measures: quick wins, medium-term improvements, capex options
-
Estimated impact: energy, cost and carbon, plus practical considerations (access, disruption, controls changes)
-
A roadmap you can action internally, tender, or deliver with our support
-
Optional DEC / advisory report support where relevant

Our approach
Step 1 – Opportunity review (quick, low disruption)
A focused on-site review to understand systems, controls, occupancy patterns and “what’s running when”—and to identify the most likely savings opportunities.
Step 2 – Baseline + energy balance
We compare design intent vs actual operation, build an energy balance and establish a baseline so opportunities are based on evidence, not assumptions.
Step 3 – Feasibility + business case (ready for sign-off)
We develop the chosen measures into a clear plan—costs, savings, payback, disruption, sequencing, and (where needed) detailed designs suitable for tender and implementation.
Step 4 – Delivery support + verification (optional)
If required, we can support procurement, commissioning and savings verification via a tailored M&V plan, so outcomes are measured and maintained over time.
