Older homes often carry charm and character, but they can struggle with energy efficiency due to outdated insulation, heating systems, and construction standards. An Energy Performance Certificate (EPC) for an older property may reveal lower ratings, which can translate into higher energy bills, reduced comfort, and even compliance issues for landlords.
Fortunately, with the right targeted EPC upgrades, you can improve comfort, reduce running costs, and increase the value of your property. If you need a professional assessment, you can book an EPC with EPCrate.
Why Older Homes Often Have Lower EPC Ratings
Older homes were built before modern energy efficiency standards. Common issues include:
Poor Insulation
Loft insulation may be minimal or uneven
Walls may be solid or cavity but uninsulated
Floors often lack thermal protection
Inefficient Heating
Old boilers or storage heaters
Lack of thermostatic radiator valves (TRVs)
No programmable controls
Single-Glazed Windows
Heat escapes more quickly compared to double or triple glazing
Draughts and Thermal Bridges
Gaps around doors, windows, and chimneys
Exposed beams or poorly insulated extensions
These factors can reduce your EPC rating significantly, often placing older homes in Bands E–G.
Key EPC Upgrades to Maximise Comfort and Savings
Even minor upgrades can significantly impact both comfort and your EPC rating. Here are the most effective improvements:
1. Improve Loft and Wall Insulation
Loft insulation: Aim for at least 270mm
Cavity wall insulation: For homes with cavity walls
Solid wall insulation: Either internal or external, depending on property structure
Insulating the property reduces heat loss, improves comfort, and is highly valued by EPC assessors.
2. Upgrade Heating Systems
Replace old boilers with condensing models
Install thermostatic radiator valves (TRVs)
Use programmable or smart thermostats for more efficient heating
Heating upgrades can drastically reduce energy bills and EPC scores.
3. Enhance Windows and Doors
Replace single-glazed windows with double or triple glazing
Seal gaps and draughts around doors and frames
Add secondary glazing if full replacement isn’t feasible
These improvements improve thermal retention and overall comfort.
4. Insulate Hot Water Systems
Add jackets to hot water cylinders
Lag exposed pipes, especially in lofts or unheated areas
Upgrade immersion heaters for better efficiency
These measures reduce energy waste and improve EPC ratings.
5. Install Small Energy-Efficiency Measures
Replace incandescent bulbs with LED lighting
Install radiator reflectors to minimise heat loss
Ensure heating zones are optimised using timers
Even small improvements are recognised in EPC calculations and increase overall energy efficiency.
6. Consider Renewable Energy Options
Solar panels or solar water heating can boost ratings
Heat pumps may be suitable for properties with high heating demands
Renewable solutions also future-proof the home against stricter energy efficiency regulations.
EPC Assessment: Why Professional Guidance Matters
Older homes have unique challenges. A professional EPC assessor can:
Identify high-impact improvements for your specific property
Recommend upgrades that provide the best cost-to-benefit ratio
Issue an official EPC certificate for compliance or sale purposes
Book your assessment with EPCrate for accurate guidance:

Benefits of EPC Upgrades in Older Homes
Lower Energy Bills: Efficient insulation and heating reduce annual costs.
Increased Comfort: Better thermal performance means warmer winters and cooler summers.
Improved EPC Rating: Boosts property value and attractiveness to buyers or tenants.
Compliance: Meets legal requirements for rented properties.
Environmental Impact: Reduces carbon footprint and contributes to sustainability.
Final Thoughts
Even older properties can achieve high EPC ratings and energy efficiency with targeted upgrades. Focus on insulation, heating, windows, hot water, and small efficiency measures to maximize comfort and savings.
