Welcome to CSR Sustain

Nationwide providers of Commercial Energy Saving Surveys - helping you to save energy and reduce costs for your organisation.

Who We Are

CSR Sustain was established in 2008 to provide energy assessment services to property professionals throughout the UK in providing compliance energy assessments and audits mandated under the Energy Performance in Buildings Directive (EPBD).

The team is led by Managing Director Gary Cleary, supported by Technical Director Craig Kefford and Operations Manager Michelle Booth. We have been providing compliance documentation such as EPCs and DECs and Air Conditioning Inspections (TM44) since 2008.

We are known as a no nonsense, reliable provider with the experience of dealing with all manner of building and energy compliance related issues.

We have developed to provide bespoke energy audits, consultancy roles including CRC Energy Efficiency Scheme and now provide support as ESOS Lead Assessors.

Working nationally and increasingly in the South – (recently creating a base in London), we have developed a national team of associates who can deal with both volume assignments and a high level of consultancy services to meet the ever increasing demand for C02 reduction targets, fuel cost savings, design stage assessments and funding applications for renewable technologies.

We welcome enquires for all energy related audits and consultancy services and actively seek to work in a partnering arrangement with all our clients.

We pride ourselves on providing “flexible solutions to complex problems”.
