When striving for a high Energy Performance Certificate (EPC) rating, many property owners overlook one critical detail: outdated heating controls. Manual thermostats and old dial-based systems are still prevalent in UK homes, but these seemingly minor components can significantly impact your EPC score.
Why Do Manual Thermostats Lower Your EPC Rating?
EPC assessors evaluate a property’s ability to regulate and optimise energy use. Heating controls are a key factor because they influence how efficiently a heating system operates. Manual thermostats:
Lack precision in maintaining consistent indoor temperatures.
Do not support zonal heating (controlling individual rooms independently).
Offer no automation, often leading to unnecessary energy use.
As a result, homes with basic or manual heating controls are marked down in the EPC software calculations, especially when compared to properties equipped with programmable or smart thermostats.
How Much Can Heating Controls Affect My EPC?
While the exact impact varies, outdated heating controls can downgrade your EPC rating by one to two bands, especially in older properties with no other modern energy-saving upgrades. This downgrade can make the difference between a compliant property and one that fails rental or sale requirements under the Minimum Energy Efficiency Standards (MEES).
Simple Upgrade, Big Gains: The Case for Smart Controls
Upgrading to programmable or smart heating controls is a relatively low-cost improvement with a high return on EPC scoring. Benefits include:
Zonal Control: Heat only the rooms in use.
Automation: Scheduled heating reduces waste.
Remote Access: Manage your heating via smartphone apps.
Modern controls signal to the EPC assessor that the property has better operational efficiency, potentially boosting your score significantly.
Do I Need a New EPC After Upgrading My Heating Controls?
Yes. Any improvement to your heating system, including the addition of smart thermostats or TRVs (thermostatic radiator valves), warrants an EPC reassessment. At Urgent EPC, we offer same-day EPC assessments to ensure your upgraded property reflects its true efficiency potential. Book your reassessment now and avoid the risk of an outdated certificate impacting your compliance or property value.
