How to Improve Your EPC Rating
Find the most practical and cost-effective improvements for your property before committing to expensive upgrades
Improving an EPC rating is rarely about making one single change.
​
A property’s energy performance is influenced by a combination of factors including insulation, heating, hot water, glazing, ventilation, controls and renewable technologies. The right improvements depend on the construction of the property, its current condition, its existing EPC rating and how much you are prepared to invest.
​
That is why the best way to improve an EPC rating is usually to look at the property as a whole rather than simply choosing the first improvement recommended on an EPC certificate.
​
Which improvements can increase an EPC rating?
Depending on the property, improvements may include:
-
loft and roof insulation
-
internal or external wall insulation
-
floor insulation
-
improved windows and glazing
-
more efficient heating systems
-
heating controls and smart thermostats
-
hot-water improvements
-
heat pumps
-
solar panels
-
battery storage
-
improved ventilation
-
energy-efficient lighting
​
Some measures are relatively inexpensive. Others can cost many thousands of pounds.
​
The important question is not simply:
​
What can I install?
​
It is:
​
Which improvements are most appropriate for this particular property, and which should be carried out first?
​
​
Improving an EPC from D to C
Many property owners are specifically looking for ways to move a property from EPC D to EPC C.
​
In some properties this may be achieved through a combination of relatively straightforward improvements such as insulation, heating controls or hot-water upgrades.
​
In others, reaching a higher rating may require more substantial improvements to the building fabric, heating system or renewable energy provision.
​
The most cost-effective route will depend on what is already installed and where the greatest areas of energy loss are occurring.
​
​
Improving an EPC from E to C
Moving from EPC E to EPC C can require a more substantial programme of improvement.
​
Older properties may have poorly insulated roofs, solid walls, inefficient heating systems or outdated glazing. Simply replacing one element may not provide the improvement expected.
​
A coordinated approach can help identify which upgrades are likely to provide the greatest benefit and avoid spending money on measures that deliver relatively little improvement.
​
​
Should you follow the recommendations on your EPC?
Your EPC is a useful starting point, but the recommendations should not necessarily be treated as a shopping list.
​
Two apparently similar properties can perform very differently depending on their construction, orientation, heating system, ventilation and previous alterations.
​
Before investing heavily in insulation, new windows, solar panels, a heat pump or another major improvement, it is sensible to consider how that measure fits into the overall performance of the property.

​
Get the whole picture before you spend
APN Green Homes provides an independent Green Home Assessment designed to help you understand which improvements may be most suitable for your property.
​
We consider the home as a complete system, looking at areas such as:
-
insulation and heat loss
-
walls, floors and roofs
-
windows and glazing
-
heating and hot water
-
ventilation
-
solar panels and battery storage
-
heat pumps
-
cooling
-
available grants and incentives
-
the order in which improvements should be considered
​
The aim is to help you make informed decisions before committing thousands of pounds to individual products or installations.
​
​
Independent advice, not product sales
APN Green Homes does not need to sell you a heat pump, solar panels, windows or insulation.
​
Our role is to help you understand what is appropriate for your property.
​
That independence is particularly important when different installers may naturally recommend the product or service they provide.
​
A whole-home assessment allows you to step back and consider the bigger picture first.

If you are looking to improve your EPC rating and want to understand which upgrades should take priority, our Green Home Assessment provides a practical starting point.
​
Your personalised report will review the information you provide about your property and set out the improvements and technologies that may be worth considering, together with suggested priorities and relevant grant or incentive information.
