Heritage or listed properties are cherished for their character, history, and architectural features. However, when it comes to Energy Performance Certificates (EPCs), these homes often face unique challenges. Even minor renovations may not lead to significant EPC improvements, leaving homeowners and landlords frustrated.

At Urgent EPC, we work with owners of heritage properties to explain why these homes struggle with EPC ratings and how to approach energy efficiency without compromising historical value.

Understanding the EPC Challenge for Heritage Homes

EPCs assess a property’s energy efficiency based on:

• Insulation levels

• Heating systems

• Windows and doors

• Airtightness and ventilation

• Renewable energy sources

For heritage homes, meeting modern energy efficiency standards can be difficult because:

1. Original Materials Cannot Be Altered
   Many heritage properties have restrictions on replacing windows, doors, or walls. Upgrading to modern double glazing or wall insulation may be prohibited, leaving the property inherently less energy-efficient.

2. Solid Walls Limit Insulation Options
   Older buildings often have solid walls rather than cavity walls. Installing insulation without damaging the structure or appearance is challenging, which directly impacts EPC scores.

3. Conservation Rules Restrict Alterations
   Planning and conservation regulations may prevent certain interventions, such as roof insulation or external wall cladding. EPC assessors have to rate the property based on existing materials and permitted upgrades.

4. Inefficient Heating Systems
   Heritage homes may rely on older boilers, radiators, or fireplaces. Retrofitting modern heating systems without affecting the building’s fabric can be complicated and expensive.

5. Complex Layouts and Extensions
   Heritage properties often have multiple floors, extensions, and irregular layouts, which complicate energy assessments. Thermal bridging and uneven insulation can further reduce EPC scores.

How Heritage Homeowners Can Improve EPC Ratings

Even with restrictions, there are ways to improve energy efficiency without compromising character:

• Internal Wall Insulation: Non-invasive insulation can reduce heat loss while preserving external facades.

• Secondary Glazing: Enhances window performance without altering original windows.

• Efficient Heating Controls: Smart thermostats and zoned heating systems can optimise energy use.

• Loft Insulation: Often permitted and highly effective.

• Renewable Energy Integration: Solar panels or heat pumps where regulations allow.

Documentation of all interventions is crucial for EPC assessors to accurately reflect improvements.
