Can I Reach the Highest EPC Rating by Doing Only the Final Recommendation?
Not necessarily.
The improvement measures listed in an Energy Performance Certificate (EPC) are designed to show a range of possible upgrades, and each measure contributes differently to the overall energy rating. Because of this, carrying out only the final or last recommendation will not usually result in the highest possible EPC rating.
How EPC Improvements Work
Each recommendation in an EPC is based on how the property’s energy performance is modelled. Some measures have a greater impact than others, and the most effective improvements are often those that reduce heat loss first, such as insulation, before addressing heating system efficiency.
For this reason, EPC improvement measures are usually designed to work together rather than in isolation.
Why the Final Recommendation Alone May Not Be Enough
Later-stage recommendations often assume that earlier improvements have already been made. As a result, completing only the final suggested measure may:
Deliver a limited improvement in energy rating
Not address underlying heat loss or efficiency issues
Provide less benefit than a combined approach
What This Means in Practice
To achieve the highest possible EPC rating, it is often necessary to consider a combination of improvements, rather than relying on a single measure.
However, all EPC recommendations are optional, and property owners can choose which improvements to carry out based on budget, practicality, and priorities.
Summary
Completing only the final recommendation is unlikely to result in the maximum possible EPC rating. A more effective approach is usually a combination of measures that work together to improve overall energy performance.
At A1 Home Inspectors, we present EPC recommendations clearly so property owners can understand how different improvements contribute to the overall rating and make informed decisions.
