EPC Recommendations Explained: Which Ones Actually Matter?

Understanding EPC Recommendations: A Detailed Breakdown

A commercial EPC has always incorporated a Recommendations Report (RR) that immediately follows the coloured graph grade, this has been the case since the EPC national measurement system started in 2008.The RR is a largely computer-generated document and normally contains no more than one side of A4 suggested areas for improvement. It was never intended as a definitive document; it merely gives a landlord suggested areas to investigate.

Vital produces bespoke EPC Plus upgrade reports for commercial landlords to establish a definite pathway to EPC grade C, B and A. Vitals EPC plus report also contains estimated capital costings for each improvement measure. This is a uniform nationwide service for both small and large commercial buildings.

An EPC recommendation report is generated by accredited energy assessors using methodologies like the Simplified Building Energy Model (SBEM) for commercial properties. This report, valid for 10 years, provides suggestions for improving energy efficiency, categorised by payback periods—typically under 3 years for cost-effective measures and up to 7 years for longer-term investments. Unlike domestic EPCs, which might suggest minor changes like replacing light bulbs, commercial EPC recommendations are tailored for larger-scale operations, addressing offices, retail spaces, and industrial buildings.

The recommendations are not mandatory but are designed to help property owners identify cost-saving opportunities and potential upgrades. They cover a range of areas, including lighting, heating, ventilation, air conditioning (HVAC), insulation, and renewable energy integration. For instance, a typical EPC recommendation report might suggest upgrading to LED lighting, improving insulation, or installing solar panels, each with estimated savings and potential rating improvements. This process ensures that property owners can make informed decisions, balancing cost, benefit, and regulatory compliance.

Key Recommendations That Matter: Prioritising Impact

Given the diversity of commercial properties, not all EPC recommendations will have equal impact. Below, we explore the most significant areas, supported by research and industry insights, to help property owners prioritise effectively.

Lighting Efficiency: A Bright Start

Lighting is a major energy consumer in commercial buildings, accounting for approximately 20% of total energy use, according to the Building Energy Efficiency Survey 2016. EPC recommendations often suggest switching from incandescent or fluorescent bulbs to LED lighting, which consumes 70-90% less energy and has a lifespan of 50,000-100,000 hours. Additionally, installing lighting controls—such as motion sensors, dimmer switches, and timers—can reduce energy consumption by up to 30%, enhancing both efficiency and cost savings. For example, a dimmer switch might cost around £90, while motion sensors range from £20-£100, with tax relief available through Enhanced Capital Allowances (ECA) schemes, making this a cost-effective measure with a short payback period.

Heating and Cooling Systems: Balancing Comfort and Efficiency

HVAC systems are another critical area, often responsible for 55-60% of annual energy spend in commercial properties. EPC recommendations frequently advise upgrading to high-efficiency boilers (92% efficient since April 2018) or heat pumps and implementing variable speed drives for better control. Regular maintenance, such as cleaning filters and checking for leaks, can extend system lifespan and reduce energy bills. Moreover, lowering thermostat settings by 1°C can save 8% on heating costs, a simple yet effective measure. For properties seeking innovative solutions, passive heating and cooling techniques, such as natural ventilation and thermal mass, can complement these systems, reducing reliance on mechanical cooling and heating.

Insulation and Building Fabric: Sealing the Deal

Improving insulation is a cornerstone of energy efficiency, particularly for older commercial buildings built before the 1990s, which may not meet current standards. EPC recommendations often include enhancing roof, wall, and floor insulation to minimise heat loss, as well as upgrading to double or triple glazing to improve thermal performance. Sealing gaps and cracks enhances airtightness, reducing drafts and maintaining indoor temperatures. These measures can significantly lower heating and cooling demands, with potential savings highlighted in the recommendation report, making them a priority for properties with poor thermal efficiency.

Renewable Energy: Harnessing the Future

Incorporating renewable energy sources, such as solar photovoltaic (PV) panels or wind turbines, is another common EPC recommendation, especially for properties with suitable roof space or open areas. Solar panels, costing between £1,500-£8,000, can generate electricity and reduce grid reliance, with a lifespan of over 25 years. This measure, though initially costly, aligns with sustainability goals and can enhance property value, attracting tenants who prioritise green credentials.

Passive Heating and Cooling Techniques: Leveraging Natural Design

Passive heating and cooling techniques, utilise building design and natural elements to regulate indoor temperatures, reducing energy demands. These methods are particularly relevant for commercial properties, where large spaces and high occupancy can lead to significant heating and cooling needs. Examples include:

Building Orientation and Layout: Designing the building to maximise solar gain in winter, using south-facing windows, and minimising it in summer through strategic shading, such as overhangs or awnings.
Thermal Mass: Incorporating materials like concrete or brick to absorb heat during the day and release it at night, stabilising indoor temperatures.
Natural Ventilation: Implementing operable windows, vents, or atriums to promote airflow, reducing the need for mechanical cooling, especially in warmer months.
Shading: Using external shading devices or vegetation to block direct sunlight, preventing overheating and reducing air conditioning demands.
Insulation: While also covered earlier, proper insulation enhances passive temperature regulation by maintaining indoor conditions without additional energy input.

These techniques are often recommended in EPCs for new builds, where design can be optimised, but can also be retrofitted into existing buildings, such as adding shading devices or improving ventilation systems. By integrating passive heating and cooling techniques, property owners can enhance occupant comfort, reduce energy bills, and potentially improve their EPC rating, aligning with sustainability objectives.

Implementing Recommendations: A Strategic Approach

Deciding which EPC recommendations to implement requires a strategic approach, considering several factors:

Cost vs. Benefit: Evaluate the initial investment against expected energy savings and potential increases in property value. For instance, LED lighting upgrades might have a payback period of 3 years, while solar panels could take longer but offer long-term benefits.
Payback Period: Prioritise measures with shorter payback periods for quicker returns, such as lighting controls or insulation improvements, while longer-term investments like renewables can be planned for future budgets.
Regulatory Compliance: Ensure compliance with current and future standards, such as the proposedupcoming EPC C rating by 2027, to avoid penalties, which can range from £500 to £5,000 based on rateable value for non-compliance.
Occupant Impact: Consider how changes will affect building users, aiming for minimal disruption during implementation, such as scheduling HVAC upgrades outside business hours.
Government Incentives: Explore available grants or schemes, such as Enhanced Capital Allowances for energy-efficient equipment, to offset costs and enhance feasibility.

By assessing these factors, property owners can create a phased implementation plan, aligning with financial resources and sustainability goals, ensuring both compliance and cost-effectiveness.

Taking Action for Efficiency

EPC recommendations, as explained throughout this article, provide a roadmap for enhancing the energy efficiency of commercial properties, crucial for reducing operational costs, meeting regulatory requirements, and contributing to environmental sustainability. Key areas like lighting efficiency, HVAC upgrades, insulation, renewable energy, and passive heating and cooling techniques offer significant potential, with varying impacts based on property specifics.
