Top 10 Ways to Achieve an EPC Rating of C

Top 10 Ways to Achieve an EPC Rating of C

From 2030, most rental properties in England and Wales must reach an EPC rating of C before they can be legally let.

While you cannot change how an EPC is calculated, you can make sure your property is assessed accurately and scores as highly as possible.

These simple steps often make the difference between passing and failing.

1. Provide All Upgrade Evidence

EPC assessors must use assumptions if no proof is supplied. Provide invoices, certificates and warranties for:

  • Loft, cavity or solid wall insulation
  • Boilers and heating systems
  • Double or triple glazing
  • Solar panels or renewables

Missing paperwork can push a property down a whole EPC band

2. Ensure Full Property Access

A critical step for landlords seeking EPC C compliance is making sure the assessor can access all areas of the property. This includes lofts, boiler cupboards, meters, and basements. If assessors cannot inspect, these areas are marked as “unknown,” which reduces your EPC score and could prevent reaching band C.

3. Highlight Hidden Improvements

Many landlords install energy-saving features that are not immediately visible. Items such as underfloor insulation, pipe lagging, hot water tank jackets, and smart heating controls can significantly improve your EPC rating. Make sure the assessor knows about these improvements to accurately credit your property.

4. Install Modern Heating Controls

Landlords can gain important EPC points by installing smart thermostats, programmable timers, thermostatic radiator valves (TRVs), and zoning controls. These modern heating upgrades are cost-effective and can make a real difference in achieving EPC band C for your rental property.

5. Fit LED or Low-Energy Lighting

Even lighting contributes to EPC scoring. Landlords should replace traditional halogen or incandescent bulbs with LED or other energy-efficient alternatives. This simple step can earn extra points and is an easy way to move closer to EPC C compliance.

6. Upgrade Loft Insulation

Proper loft insulation is a high-return improvement for landlords aiming for EPC C. The recommended standard is 270mm or more, and topping up insulation is one of the most effective ways to improve your property’s energy efficiency score.

7. Lag All Hot Water Pipes

Landlords can improve an EPC rating by insulating all hot water pipes. Unlagged pipes waste heat and reduce overall energy efficiency, whereas pipe lagging is inexpensive and contributes directly to achieving EPC band C.

8. Improve or Evidence Glazing

Windows play a major role in a property’s EPC rating. Landlords should consider upgrading to double or triple glazing if necessary, or at the very least provide proof of existing glazing. Proper documentation ensures the assessor credits these improvements toward a higher EPC score.

9. Draught-Proof the Property

Landlords can increase EPC scores by sealing gaps around doors, windows, loft hatches, and letterboxes. Draught-proofing prevents heat loss, improves energy efficiency, and is a low-cost measure to help achieve EPC band C compliance.

10. Use an EPC-Aware Assessor

Not all EPC assessors understand the specific requirements landlords face. LandlordEPCs has extensive experience with landlord compliance and EPC band C requirements. We ensure your evidence is correctly recorded, all energy-saving improvements are fully credited, and your property has the best possible chance of achieving a C rating.

Don’t Wait Until 2030

Landlords risk losing rental income if their properties fail to meet the EPC C requirement. A pre-EPC inspection identifies the cheapest improvements, avoids unnecessary work, and ensures full compliance.
