Our ESOS Audit
• Same data as collected for CSR reporting
• Used energy cost to exclude more small
offices
• Best fit for business – included buildings
we own as more scope for savings
• Auditing 7 offices & business car travel
• 11 excluded but <10% energy use
• Fleet cars excluded <1% energy use & high
comparative cost to audit
