Start onlineDoes anything on your EPC look wrong?
If one of these sounds like your certificate, we can help you establish what has happened.
Wrong EPC rating
Your rating appears lower or different from what you expected.
Unexpectedly low EPC score
Significant improvements may have been made to the property but the score does not appear to reflect them.
Incorrect property type
Your certificate appears to describe the wrong type or configuration of property.
Missing insulation
Loft, wall, floor or other insulation may not appear to have been recognised.
Incorrect heating system
The EPC may list the wrong boiler, heating type, controls or other system.
Wrong wall construction
The property construction recorded on the EPC may not reflect the building accurately.
Wrong floor type
Suspended, solid or other floor construction may appear incorrectly recorded.
Incorrect glazing information
Double glazing, triple glazing, window age or glazing proportion may appear inaccurate.
Incorrect property measurements
Floor area or dimensional information may appear inconsistent with the property.
Recommendations that do not make sense
The EPC may recommend improvements that appear inappropriate or already completed.
Previous EPC significantly different
Your property may previously have been rated C but is now rated D or E without an obvious explanation.
An EPC affecting a sale, letting or remortgage
An unexpected EPC may cause delays or questions during a transaction.
Your EPC can matter for more than energy bills
An EPC may influence decisions around selling, letting, buying, remortgaging and improving a property. Some mortgage lenders offer particular products, incentives or affordability treatment for more energy-efficient homes, while landlords must also comply with minimum energy-efficiency requirements when letting qualifying properties. That means an EPC containing inaccurate property information could potentially have consequences beyond the certificate itself.
Mortgages & remortgaging
Some lenders offer green mortgage products, incentives or lending benefits linked to qualifying EPC ratings, and a rating can form part of how energy costs are considered.
Concerned about your EPC rating?Renting your property
Energy-efficiency rules can restrict the letting of qualifying properties with very low EPC ratings unless a valid exemption applies.

Buyers increasingly consider running costs and energy performance alongside a property's price and condition.

Energy efficiency can be one factor affecting how buyers and investors perceive a property.
Request an EPC second opinionIf your EPC is genuinely inaccurate, the consequences could be bigger than a letter on a certificate.
A better EPC can create opportunities. An inaccurate EPC can create unnecessary problems. In England and Wales the current minimum for letting most qualifying private rented homes is band E, not C — we will always explain what applies to your property rather than quote future proposals as if they are already law.
A lower EPC rating does not necessarily mean an assessor has made a mistake.
Our job is not to assume the EPC is wrong. Our job is to help you understand whether it makes sense.

- Physical changes to the property since the last assessment
- The approved assessment methodology and how it treats each element
- RdSAP methodology updates between one certificate and the next
- Default assumptions that must be applied where evidence is unavailable
