Protecting the value of commercial property in a net-zero economy
From statutory survey to net zero — one accountable partner for your portfolio's energy performance, and one team that stays to keep it performing.
Better building performance. Built around your responsibilities.
Whether you own, manage or operate buildings, we help you understand their performance, prioritise improvements and demonstrate progress—from a single property to an entire estate.
Owners and investors
Protect asset value. Plan investment with confidence.
Understand compliance exposure, improve energy performance and prioritise investment across your portfolio. We connect assessments, engineering advice and ongoing optimisation to support lettability, control operating costs and protect long-term value.

Public-sector and education estates
Make limited budgets work harder across your estate.
Build a clearer picture of compliance, energy use and building condition across council properties, schools, academies and other public-service buildings. We help estates teams prioritise surveys and improvements, plan work around operational needs and track progress against energy and carbon objectives.

A decade of mandatory upgrade, and a fragmented supply chain
Owners face converging pressures on asset value. Meeting them piecemeal, through a dozen disconnected suppliers, is slow, costly and hard to evidence.
Regulatory deadlines
MEES tightening toward EPC B by 2031. Sub-standard assets risk becoming unlettable and stranded.
Rising energy cost
Ageing plant and inefficient HVAC quietly erode net operating income year after year.
ESG & investor scrutiny
Owners must evidence carbon performance to funds, lenders and occupiers, with real data.
Fragmented delivery
Surveyors, consultants, designers and contractors rarely join up. No single line of accountability.
Assess
Statutory compliance surveys and performance benchmarking — EPC, DEC, TM44 and NABERS UK.
Where we startAdvise
Decarbonisation, MEES strategy and CAPEX planning, with a costed, prioritised route to compliance.
The planDesign
M&E and HVAC engineering design, lifecycle plant replacement and electrification of heat.
The solutionDeliver
Client-side technical project management and retrofit delivery, coordinating contractors from design to completion.
The worksOptimise
Prevent energy drift. Close the performance gap. Keep the asset performing.
OngoingPortfolio intelligence
Know where to act. Invest with confidence
Which buildings need attention first? Where is information missing? Which improvements deserve investment?
CSR Sustain brings property information, energy assessments and engineering insight together to help owners and estate managers understand their position and prioritise action across a portfolio.
Identify exposure
Understand where certification gaps, poor energy performance and incomplete information require attention. Distinguish confirmed issues from areas needing further investigation.
Prioritise surveys and investment
Focus assessments on the buildings where better evidence will make the greatest difference. Develop a programme of improvements informed by compliance needs, building condition, energy-saving opportunities and available budgets.
Track progress across your estate
Establish a clear baseline and maintain a consistent view of assessments, recommended actions and completed improvements. Use updated evidence to review priorities and demonstrate progress.
Start with the information you already hold
We’ll help identify the gaps, agree what needs checking and set out practical next steps.

CSR PEAK — we don't just certify your building, we keep it performing
Most providers hand you a certificate and leave. PEAK combines continuous monitoring with expert HVAC engineering advisory — turning a one-off survey into year-on-year performance.
Continuous fault detection
Automated fault detection and diagnosis (aFDD) identifies faults and efficiency losses as they happen.
Expert HVAC advisory
Our engineers translate the data into practical interventions — not just dashboards.
Evidenced performance
Hard data for ESG and investor reporting — and to protect asset value.
Built around the owner — not the transaction
One accountable partner
From survey to optimisation, one team owning the outcome from baseline to results.
Real engineering depth
Full M&E design and delivery capability sits alongside our compliance expertise.
Data-driven & independent
CSR PEAK turns building performance into objective evidence for funds, lenders and occupiers — measured, not asserted.
Aligned to your asset value
Protecting lettability, net operating income and long-term asset value through better building performance.
A low-friction way to begin
Most owner relationships begin with a single building or a compliance review, then grow as we prove value.
