Why do an Energy Audit?

Financial benefits

Energy audits benefit companies by informing directors how much energy is costing their business and crucially where it is being used. Armed with this information it is generally possible to identify low and no cost saving measures through better energy management. Furthermore the audit provides the information needed to assess investment in energy saving opportunities. While energy costs are often a small part of the business’s total costs the saving feed through to the bottom line profits. The real measure of the benefits of energy cost saving is the increase in turnover that would be required to achieve the same increase in profits.

Improving the company’s green credentials

While directors rightly focus on profits and return on investments, it is becoming increasingly important to be seen to be taking steps to protect the environment. Investors and customers want to know how the business is going to reduce greenhouse gas emissions. Investment funds are transferring funds from polluting companies to more sustainable businesses resulting in higher borrowing costs for polluting companies.  Our energy audit provides the essential information and insight into where and how energy is used in order to begin to address these issues

Our audit includes all energy use in buildings, by process and by transport


Colin Lillicrap Associates has been auditing large companies since the introduction of the Energy Saving Opportunities Scheme (ESOS) in 2014. Colin Lillicrap is a CIBSE Certified Low Carbon Consultant with 22 years’ experience of research into energy intensive industrial processes followed by a period at the Building Research Establishment managing the non-domestic part of the Energy Efficiency Best Practice programme. We have audited large offices, a construction group, factories, a logistics company, service companies and developers – case study.

An audit starts with a survey of all buildings including factories and warehouses to gather information on the building fabric and glazing, HVAC system, domestic hot water, lighting, and IT equipment. We calculate 12 months electricity and gas consumption from meter readings or utility invoices. Vehicle fuel consumption is obtained from fuel cards or recorded mileage. Where gas oil or LPG is used consumption will usually be based on recorded deliveries.

Tariffs for electricity, gas and water

We analyse the utility invoices and research the best tariffs for your business. Simply provide us with a sample utility bills and we will compare your current tariffs with the best available in the market. If you have half hour meter readings we can investigate the possibility of load shifting to further reduce you tariffs.


Vehicle Fleet Reviews

Company vehicle often account for a significant part of the total energy consumption and greenhouse gas emissions. With the phasing out of diesel and petrol vehicles from 2030 it is time to review your fleet management and the vehicle you operate. We analyse the information  we gather during the audit and advise on measure to reduce emissions and make the business case for progressively replacing your fleet with electric alternatives.

Energy Saving opportunities

The data from the audit is the starting point for analysing where energy is used and identifying energy saving opportunities.
