Commercial Energy Audit in London(MEES compliant)

Question: What is a commercial energy audit?

Answer: A commercial energy audit is a systematic assessment of how a building or organisation uses energy and where savings can be made. The auditor reviews energy bills and meter data, surveys the building fabric, heating, cooling, ventilation, lighting and equipment, and identifies energy-saving opportunities with estimated savings, costs and payback periods.

Energy audits are used to reduce running costs, improve EPC ratings for MEES compliance, satisfy ESOS obligations and inform net zero carbon plans.

Question: What are the Minimum Energy Efficiency Standards (MEES)?

Answer: The Minimum Energy Efficiency Standards, introduced under the Energy Efficiency (Private Rented Property) Regulations 2015, make it unlawful to let non-domestic property in England and Wales with an EPC rating below E, unless an exemption applies. Since April 2023 this has applied to all existing leases, not just new lettings. The Government has consulted on raising the minimum standard to EPC C by 2027 and B by 2030, which would affect a large proportion of the commercial building stock.

Landlords with buildings rated E or below, or at risk under future standards, need a clear improvement plan.

Question: How does an energy audit help with MEES compliance?

Answer: A MEES-focused audit identifies the measures that will most cost-effectively improve the EPC rating, such as LED lighting, heating and cooling upgrades, controls, insulation and renewables, and models their effect on the EPC using SBEM. This allows landlords to prioritise investment, plan works around lease events and avoid the financial penalties and letting restrictions of non-compliance. Where improvements are not cost-effective, the audit can support a valid exemption.

Question: What is ESOS and does it require an energy audit?

Answer: The Energy Savings Opportunity Scheme (ESOS) requires large UK organisations, those with 250 or more employees or turnover over £44 million and a balance sheet over £38 million, to carry out energy audits every four years. ESOS Phase 3 compliance was required by 2024 and Phase 4 by December 2027. Audits must cover at least 95 per cent of energy consumption and be signed off by a registered Lead Assessor, and organisations must now publish action plans and annual progress updates.

Question: What does an energy audit include?

Answer: A typical audit includes:

• Analysis of energy consumption data and benchmarking
• Site survey of building fabric and services
• Assessment of controls, operating hours and maintenance
• Identification of energy conservation measures
• Estimated savings, costs and payback for each measure
• EPC rating improvement modelling where required
• Prioritised action plan
• Recommendations for monitoring and verification

Audits may be carried out to BS EN 16247 for ESOS compliance.

Question: What savings can be achieved from a commercial energy audit?

Answer: Most commercial buildings can achieve savings of 10 to 30 per cent through a combination of low-cost operational measures and targeted capital investment. Lighting upgrades, controls optimisation and heating system improvements typically offer the fastest payback, while heat pumps, fabric improvements and renewables deliver the greatest carbon reductions over the longer term.
