How Many UK Properties Are Still Below EPC C?

How Many UK Properties Are Below EPC C?

It is estimated that around 60%–65% of UK residential properties currently fall below an EPC rating of C.

This means that the majority of homes in the UK are not yet meeting the level of energy efficiency that is increasingly being targeted by policymakers and the wider property market.

If you’re unsure where your property stands, you can book an EPC assessment here to find out your current rating.

What EPC Ratings Do Most UK Homes Have?

The most common EPC ratings across the UK are:

• D (most common)
• C (increasing, but not yet dominant)
• E (still significant in older housing stock)

Many properties, particularly older homes, sit just below the EPC C threshold — meaning relatively small improvements could push them into compliance.

Why Are So Many Properties Below EPC C?

There are several reasons why such a large proportion of UK homes remain below EPC C:

• Older housing stock with poor insulation
• Solid wall construction (harder to upgrade)
• Outdated heating systems
• Historic lack of energy efficiency requirements

Areas with older terraces and period properties — such as Liverpool, Manchester, and Sheffield — often have a higher proportion of lower EPC ratings.

What Does This Mean for Landlords?

For landlords, this data is particularly important.

There have been ongoing discussions around requiring rental properties to meet a minimum EPC rating of C in the future. While timelines and specifics may change, the direction of travel is clear: energy efficiency standards are tightening.

Properties below EPC C may:

• Require investment to remain lettable long-term
• Become less attractive to tenants
• Face increased running costs

Understanding your current EPC position now allows you to plan ahead rather than react later.

Regional Differences in EPC Ratings

EPC ratings can vary significantly depending on location.

• Urban areas with newer developments tend to have higher ratings
• Rural and older industrial areas often have lower ratings
• Property type and age are major influencing factors

For example, cities like London often have a mix of high-performing new builds and older properties with lower ratings.

How Easy Is It to Reach EPC C?

For many properties currently rated D or low C, reaching EPC C is achievable without major structural changes.

Common improvements include:

• Loft and wall insulation
• Upgrading heating systems
• Installing better glazing
• Improving heating controls

In many cases, targeted upgrades can move a property up a band without excessive cost.

How Much Does an EPC Cost?

Before making improvements, the first step is understanding your current rating.

EPC assessments across the UK typically range between £75 and £125, depending on property size and location.

You can arrange an EPC in areas such as Preston, Birmingham, and nationwide through a simple online booking process.

Why This Matters for the Future of UK Property

With a large percentage of UK homes still below EPC C, there is a significant gap between current housing stock and future expectations.

This creates both a challenge and an opportunity:

• Challenge: Upgrading millions of homes will require time and investment
• Opportunity: Early action can add value and improve property appeal

As awareness grows, EPC ratings are likely to play an increasingly important role in buying, selling, and renting property.

Final Thoughts

The reality is clear — most UK properties are still below EPC C.

Whether you're a landlord, homeowner, or investor, understanding your EPC rating is becoming essential.

The sooner you assess your property, the easier it is to plan improvements and stay ahead of future changes.
