Smart meters are rapidly becoming the standard across UK households and commercial premises, enabling better energy monitoring and accurate billing. But do they actually improve your Energy Performance Certificate (EPC) rating?
Here’s what property owners, landlords, and developers in London need to know about the link between smart meters and EPC assessments.
🧾 What Is an EPC Rating Based On?
Your EPC rating is calculated based on permanent building features, including:
Wall, floor and roof insulation
Heating systems and controls
Glazing and draught-proofing
Lighting (specifically low-energy bulbs)
Importantly, energy usage behaviour or billing does not influence the rating directly — even if your smart meter shows low consumption. That’s because EPCs are based on theoretical energy efficiency, not real-time usage.
📡 So, Do Smart Meters Help or Not?
Technically, smart meters do not directly increase your EPC rating — they’re not a rated element within the Standard Assessment Procedure (SAP) used for domestic EPCs, or SBEM for commercial properties.
However, here’s how they can indirectly benefit your energy efficiency:
✅ Enable Targeted Energy Improvements
Smart meters allow homeowners and landlords to:
Track energy spikes
Detect inefficiencies
Justify upgrades (like switching to low-energy lighting or heating controls)
By acting on smart meter insights, you can make changes that do improve your EPC score.
✅ Support Future Smart Home Integration
Some advanced heating systems or zoning controls that are EPC-relevant (e.g., smart thermostats) may benefit from integration with smart meters — allowing more precise energy management and better rating potential.
🔌 What About Commercial Properties?
For non-domestic EPCs, energy monitoring systems (EMS) and Building Management Systems (BMS) play a similar role. While not scored directly, they help identify inefficiencies and support EPC-improving retrofits.
🏙️ EPCs in London: What Our Assessors Say
At EPCrate, our accredited London EPC assessors often advise clients using smart meters to:
Pair them with heating upgrades or insulation
Install zoned heating controls or timers
Transition to high-efficiency LEDs (which are counted in your EPC)
Though a smart meter alone won’t boost your score, it becomes a valuable tool in an energy upgrade journey.
💡 Summary: Smart Meter = Smart Planning
| Element | Affects EPC Rating? | Benefit |
|---|---|---|
| Smart Meter Alone | ❌ No | Insight for improvements |
| Smart Heating Controls | ✅ Yes | Can raise EPC |
| LED Lighting | ✅ Yes | Direct score improvement |
| Energy Monitoring | ✅ Indirect | Informs strategic upgrades |
